11 | This package provides official Python Database API 2.0-compliant driver for the open
12 | source relational database Firebird®. In addition to the minimal feature set of
13 | the standard Python DB API, this driver also exposes the new (interface-based)
14 | client API introduced in Firebird 3, and number of additional extensions and
15 | enhancements for convenient use of Firebird RDBMS.

25 | ## Installation
26 |
27 | Requires: Firebird 3+
28 |
29 | ```console
30 | pip install firebird-driver
31 | ```
32 | See [firebird-lib](https://pypi.org/project/firebird-lib/) package for optional extensions
33 | to this driver.
34 |
35 | ## License
36 |
37 | `firebird-driver` is distributed under the terms of the [MIT](https://spdx.org/licenses/MIT.html) license.
38 |
39 | ## Documentation
40 |
41 | The documentation for this package is available at [https://firebird-driver.readthedocs.io](https://firebird-driver.readthedocs.io)
42 |
43 | ## Running tests
44 |
45 | This project uses [hatch](https://hatch.pypa.io/latest/) , so you can use:
46 | ```console
47 | hatch test
48 | ```
49 | to run all tests for default Python version (3.11). To run tests for all Python versions
50 | defined in matrix, use `-a` switch.
51 |
52 | This project is using [pytest](https://docs.pytest.org/en/stable/) for testing, and our
53 | tests add several options via `tests/conftest.py`.
54 |
55 | By default, tests are configured to use local Firebird installation via network access.
56 | To use local installation in `embedded` mode, comment out the section:
57 | ```
58 | [tool.hatch.envs.hatch-test]
59 | extra-args = ["--host=localhost"]
60 | ```
61 | in `pyproject.toml`.
62 |
63 | You can also use firebird driver configuration file to specify server(s) that should be
64 | used for testing, and then pass `--driver-config` and `--server` options to `pytest`.

6 | Installation
7 | ************
8 |
9 | Firebird-driver is written as pure-Python module (requires Python 3.8+) on top of
10 | Firebird client library (fbclient.so/dll) using ctypes_. Driver supports Firebird version
11 | 3.0 and higher.
12 |
13 | Firebird-driver is distributed as `setuptools`_ package and the preferred installation
14 | method is via pip_ tool.
15 |
16 | Installation from PYPI_
17 | =======================
18 |
19 | Run pip::
20 |
21 | $ pip install firebird-driver
22 |
23 | Quick-start Guide
24 | *****************
25 |
26 | This brief tutorial aims to get the reader started by demonstrating elementary usage of
27 | Firebird-driver. It is not a comprehensive Python Database API tutorial, nor is it
28 | comprehensive in its coverage of anything else.
29 |
30 | The numerous advanced features of Firebird-driver are covered in another section of this
31 | documentation, which is not in a tutorial format, though it is replete with examples.
32 |
33 | Driver configuration
34 | ====================
35 |
36 | The driver uses configuration built on top of `configuration system
`
37 | provided by `firebird-base`_ package. In addition to global settings, the configuration
38 | also includes the definition of connection parameters to Firebird servers and databases.
39 |
40 | The default configuration connects to embedded server using direct/local connection method.
41 | To access remote servers and databases (or local ones through remote protocols), it's
42 | necessary to adjust default configuration, or `register` them in configuration manager.
43 |
44 | You can manipulate the configuration objects directly, or load configuration from files or
45 | strings (in `.ini-style` `ConfigParser` format).
46 |
47 | Connecting to a Database
48 | ========================
49 |
50 | **Example 1:**
51 |
52 | A simple database connection is typically established with code such as this:
53 |
54 | .. sourcecode:: python
55 |
56 | from firebird.driver import connect
57 |
58 | # Attach to 'employee' database/alias using embedded server connection
59 | con = connect('employee', user='sysdba', password='masterkey')
60 |
61 | # Attach to 'employee' database/alias using local server connection
62 | from firebird.driver import driver_config
63 | driver_config.server_defaults.host.value = 'localhost'
64 | con = connect('employee', user='sysdba', password='masterkey')
65 |
66 | # Set 'user' and 'password' via configuration
67 | driver_config.server_defaults.user.value = 'SYSDBA'
68 | driver_config.server_defaults.password.value = 'masterkey'
69 | con = connect('employee')
70 |
71 | **Example 2:**
72 |
73 | A database connection typically uses specific configuration, and is established with code
74 | such as this:
75 |
76 | .. sourcecode:: python
77 |
78 | from firebird.driver import connect, driver_config
79 |
80 | # Register Firebird server
81 | srv_cfg = """[local]
82 | host = localhost
83 | user = SYSDBA
84 | password = masterkey
85 | """
86 | driver_config.register_server('local', srv_cfg)
87 |
88 | # Register database
89 | db_cfg = """[employee]
90 | server = local
91 | database = employee.fdb
92 | protocol = inet
93 | charset = utf8
94 | """
95 | driver_config.register_database('employee', db_cfg)
96 |
97 | # Attach to 'employee' database
98 | con = connect('employee')
99 |
100 | .. note::
101 |
102 | Some parameters like 'user' and 'password' could be overridden with keyword parameters.
103 | Few parameters like 'crypt_callback' or 'no_db_triggers' could be specified **ONLY**
104 | as keyword arguments.
105 |
106 | Creating a Database
107 | ===================
108 |
109 | A database is created using `~firebird.driver.core.create_database()` function.
110 | Like `~firebird.driver.core.connect()`, this function uses configuration for specification of
111 | database parameters like page size, sweep interval etc.
112 |
113 | Executing SQL Statements
114 | ========================
115 |
116 | For this section, suppose we have a table defined and populated by the following SQL code:
117 |
118 | .. sourcecode:: sql
119 |
120 | create table languages
121 | (
122 | name varchar(20),
123 | year_released integer
124 | );
125 |
126 | insert into languages (name, year_released) values ('C', 1972);
127 | insert into languages (name, year_released) values ('Python', 1991);
128 |
129 | **Example 1**
130 |
131 | This example shows the *simplest* way to print the entire contents of
132 | the `languages` table:
133 |
134 | .. sourcecode:: python
135 |
136 | from firebird.driver import connect
137 |
138 | con = connect('test.fdb', user='sysdba', password='masterkey')
139 |
140 | # Create a Cursor object that operates in the context of Connection con:
141 | cur = con.cursor()
142 |
143 | # Execute the SELECT statement:
144 | cur.execute("select * from languages order by year_released")
145 |
146 | # Retrieve all rows as a sequence and print that sequence:
147 | print(cur.fetchall())
148 |
149 | Sample output:
150 |
151 | .. sourcecode:: python
152 |
153 | [('C', 1972), ('Python', 1991)]
154 |
155 | **Example 2**
156 |
157 | Here's another trivial example that demonstrates various ways of fetching a single row at a time from a `SELECT`-cursor:
158 |
159 | .. sourcecode:: python
160 |
161 | from firebird.driver import connect
162 |
163 | con = connect('test.fdb', user='sysdba', password='masterkey')
164 |
165 | cur = con.cursor()
166 | SELECT = "select name, year_released from languages order by year_released"
167 |
168 | # 1. Iterate over the rows available from the cursor, unpacking the
169 | # resulting sequences to yield their elements (name, year_released):
170 | cur.execute(SELECT)
171 | for (name, year_released) in cur:
172 | print(f'{name} has been publicly available since {year_released}.')
173 |
174 | # 2. Equivalently:
175 | cur.execute(SELECT)
176 | for row in cur:
177 | print(f'{row[0]} has been publicly available since {row[1]}.')
178 |
179 | Sample output:
180 |
181 | .. sourcecode:: python
182 |
183 | C has been publicly available since 1972.
184 | Python has been publicly available since 1991.
185 | C has been publicly available since 1972.
186 | Python has been publicly available since 1991.
187 | C has been publicly available since 1972.
188 | Python has been publicly available since 1991.
189 |
190 | **Example 3**
191 |
192 | The following program is a simplistic table printer (applied in this example to `languages`):
193 |
194 | .. sourcecode:: python
195 |
196 | from firebird.driver import connect, DESCRIPTION_NAME, DESCRIPTION_DISPLAY_SIZE
197 |
198 | TABLE_NAME = 'languages'
199 | SELECT = f'select * from {TABLE_NAME} order by year_released'
200 |
201 | con = connect('test.fdb', user='sysdba', password='masterkey')
202 |
203 | cur = con.cursor()
204 | cur.execute(SELECT)
205 |
206 | # Print a header.
207 | for fieldDesc in cur.description:
208 | print(fieldDesc[DESCRIPTION_NAME].ljust(fieldDesc[DESCRIPTION_DISPLAY_SIZE]), end='')
209 | print() # Finish the header with a newline.
210 | print('-' * 78)
211 |
212 | # For each row, print the value of each field left-justified within
213 | # the maximum possible width of that field.
214 | fieldIndices = range(len(cur.description))
215 | for row in cur:
216 | for fieldIndex in fieldIndices:
217 | fieldValue = str(row[fieldIndex])
218 | fieldMaxWidth = cur.description[fieldIndex][DESCRIPTION_DISPLAY_SIZE]
219 |
220 | print(fieldValue.ljust(fieldMaxWidth), end='')
221 |
222 | print() # Finish the row with a newline.
223 |
224 |
225 | Sample output:
226 |
227 | .. sourcecode:: python
228 |
229 | NAME YEAR_RELEASED
230 | ------------------------------------------------------------------------------
231 | C 1972
232 | Python 1991
233 |
234 |
235 | **Example 4**
236 |
237 | Let's insert more languages:
238 |
239 | .. sourcecode:: python
240 |
241 | from firebird.driver import connect
242 |
243 | con = connect('test.fdb', user='sysdba', password='masterkey')
244 |
245 | cur = con.cursor()
246 |
247 | newLanguages = [
248 | ('Lisp', 1958),
249 | ('Dylan', 1995),
250 | ]
251 |
252 | cur.executemany("insert into languages (name, year_released) values (?, ?)",
253 | newLanguages
254 | )
255 |
256 | # The changes will not be saved unless the transaction is committed explicitly:
257 | con.commit()
258 |
259 |
260 | Note the use of a *parameterized* SQL statement above. When dealing with repetitive
261 | statements, this is much faster and less error-prone than assembling each SQL statement
262 | manually. (You can read more about parameterized SQL statements in the section on
263 | :ref:`Prepared Statements `.)
264 |
265 | After running Example 4, the table printer from Example 3 would print:
266 |
267 | .. sourcecode:: python
268 |
269 | NAME YEAR_RELEASED
270 | ------------------------------------------------------------------------------
271 | Lisp 1958
272 | C 1972
273 | Python 1991
274 | Dylan 1995
275 |
276 |
277 | Calling Stored Procedures
278 | =========================
279 |
280 | Firebird supports stored procedures written in a proprietary procedural SQL language.
281 | Firebird stored procedures can have *input* parameters and/or *output* parameters. Some
282 | databases support *input/output* parameters, where the same parameter is used for both
283 | input and output; Firebird does not support this.
284 |
285 | It is important to distinguish between procedures that *return a result set* and procedures
286 | that *populate and return their output parameters exactly once*. Conceptually, the latter
287 | "return their output parameters" like a Python function, whereas the former "yield result
288 | rows" like a Python generator.
289 |
290 | Firebird's *server-side* procedural SQL syntax makes no such distinction, but *client-side*
291 | SQL code (and C API code) must. A result set is retrieved from a stored procedure by
292 | `SELECT`-ing from the procedure, whereas output parameters are retrieved with an
293 | `EXECUTE PROCEDURE` statement.
294 |
295 | To *retrieve a result set* from a stored procedure with Firebird-driver, use code such as this:
296 |
297 | .. sourcecode:: python
298 |
299 | cur.execute("select output1, output2 from the_proc(?, ?)", (input1, input2))
300 |
301 | # Ordinary fetch code here, such as:
302 | for row in cur:
303 | ... # process row
304 |
305 | con.commit() # If the procedure had any side effects, commit them.
306 |
307 |
308 | To *execute* a stored procedure and *access its output parameters*, use code such as this:
309 |
310 | .. sourcecode:: python
311 |
312 | cur.callproc("the_proc", (input1, input2))
313 |
314 | # If there are output parameters, retrieve them as though they were the
315 | # first row of a result set. For example:
316 | outputParams = cur.fetchone()
317 |
318 | con.commit() # If the procedure had any side effects, commit them.
319 |
320 |
321 | This latter is not very elegant; it would be preferable to access the procedure's output
322 | parameters as the return value of `Cursor.callproc()`. The Python DB API specification
323 | requires the current behavior, however.

3 | The Python driver for Firebird
4 | ##############################
5 |
6 | The `firebird-driver` package provides official `Python Database API 2.0`_-compliant driver
7 | for the open source relational database `Firebird`_ ®. In addition to the minimal feature
8 | set of the standard Python DB API, this driver also exposes the new (interface-based) client
9 | API introduced in Firebird 3, and number of additional extensions and enhancements for
10 | convenient use of Firebird RDBMS.
11 |
12 | This documentation set is not a tutorial on SQL or Firebird; rather, it is a topical
13 | presentation of driver's feature set, with example code to demonstrate basic usage patterns.
14 | For detailed information about Firebird features, see the
15 | `Firebird documentation `__, and especially
16 | the excellent `The Firebird Book `__
17 | written by Helen Borrie and published by IBPhoenix_.
18 |
19 | .. seealso:: `firebird-lib`_ package for optional extensions to this driver.
20 |
21 | .. note:: Requires Python 3.11+

7 | Full text of Python Database API 2.0 (PEP 249) is available at
8 | `http://www.python.org/dev/peps/pep-0249/ `__
9 |
10 | Unsupported Optional Features
11 | =============================
12 |
13 | `Cursor.nextset`
14 |
15 | This method is not implemented because the database engine does not support
16 | opening multiple result sets simultaneously with a single cursor.
17 |
18 | Supported Optional Features
19 | ===========================
20 |
21 | - `Connection.Error`, `Connection.ProgrammingError`, etc.
22 |
23 | All exception classes defined by the DB API standard are exposed on the Connection objects
24 | as attributes (in addition to being available at module scope).
25 | - `Cursor.connection`
26 |
27 | This read-only attribute return a reference to the Connection object on which the cursor was created.
28 |
29 |
30 | Nominally Supported Optional Features
31 | =====================================
32 |
33 | `.Cursor`
34 |
35 | `~.Cursor.arraysize`
36 |
37 | As required by the spec, the value of this attribute is observed with
38 | respect to the `fetchmany` method. However, changing the value of this
39 | attribute does not make any difference in fetch efficiency because
40 | the database engine only supports fetching a single row at a time.
41 |
42 | `~.Cursor.setinputsizes`
43 |
44 | Although this method is present, it does nothing, as allowed by the spec.
45 |
46 | `~.Cursor.setoutputsize`
47 |
48 | Although this method is present, it does nothing, as allowed by the spec.
49 |
50 |
51 | Caveats
52 | =======
53 |
54 | Firebird-driver offers a large feature set beyond the minimal requirements
55 | of the Python DB API. This section attempts to document only those
56 | features that overlap with the DB API.
57 |
58 |
59 | `.Connection`
60 |
61 | `~.Connection.commit(retaining=False)`
62 | `~.Connection.rollback(retaining=False, savepoint=None)`
63 |
64 | The `commit` and `rollback` methods accept an optional boolean parameter `retaining`
65 | (default `False`) that indicates whether the transactional context of the transaction
66 | being resolved should be recycled. For details, see the Advanced
67 | Transaction Control: Retaining Operations section of this document.
68 | The `rollback` method accepts an optional string parameter `savepoint`
69 | that causes the transaction to roll back only as far as the designated
70 | savepoint, rather than rolling back entirely. For details, see the
71 | Advanced Transaction Control: Savepoints section of this document.
72 |
73 |
74 | `.Cursor`
75 |
76 | `~.Cursor.description`
77 |
78 | Firebird-driver makes absolutely no guarantees about `description` except those
79 | required by the Python Database API Specification 2.0 (that is, `description`
80 | is either `None` or a sequence of 7-element sequences). Therefore, client
81 | programmers should *not* rely on `description` being an instance of a particular
82 | class or type. Firebird-driver provides several named positional constants to be
83 | used as indices into a given element of `description` . The contents
84 | of all `description` elements are defined by the DB API spec; these
85 | constants are provided merely for convenience.
86 |
87 | .. sourcecode:: python
88 |
89 | DESCRIPTION_NAME
90 | DESCRIPTION_TYPE_CODE
91 | DESCRIPTION_DISPLAY_SIZE
92 | DESCRIPTION_INTERNAL_SIZE
93 | DESCRIPTION_PRECISION
94 | DESCRIPTION_SCALE
95 | DESCRIPTION_NULL_OK
96 |
97 | Here is an example of accessing the *name* of the first field in the
98 | `description` of cursor `cur`:
99 |
100 | .. sourcecode:: python
101 |
102 | nameOfFirstField = cur.description[0][firebird.driver.DESCRIPTION_NAME]
103 |
104 | For more information, see the documentation of Cursor.description in
105 | the `DB API Specification `__.
106 |
107 | `~.Cursor.rowcount`
108 |
109 | Although `Cursor` in Firebird-driver implement this attribute,
110 | the database engine's own support for the determination of
111 | "rows affected"/"rows selected" is quirky. The database engine only
112 | supports the determination of rowcount for `INSERT`, `UPDATE`,
113 | `DELETE`, and `SELECT` statements. When stored procedures become
114 | involved, row count figures are usually not available to the client.
115 | Determining rowcount for `SELECT` statements is problematic: the
116 | rowcount is reported as zero until at least one row has been fetched
117 | from the result set, and the rowcount is misreported if the result set
118 | is larger than 1302 rows. The server apparently marshals result sets
119 | internally in batches of 1302, and will misreport the rowcount for
120 | result sets larger than 1302 rows until the 1303rd row is fetched,
121 | result sets larger than 2604 rows until the 2605th row is fetched, and
122 | so on, in increments of 1302. As required by the Python DB API Spec,
123 | the rowcount attribute "is -1 in case no executeXX() has been
124 | performed on the cursor or the rowcount of the last operation is not
125 | determinable by the interface".
126 |
127 | .. note::
128 |
129 | This attribute is just an alias for `.Cursor.affected_rows` property.

5 | firebird.driver.config
6 | ======================
7 |
8 | This module defines the configuration system for the firebird-driver.
9 | It uses an INI-style format managed via the `DriverConfig` class, which
10 | allows defining settings for the driver itself, default server/database
11 | parameters, and named configurations for specific servers and databases.
12 |
13 | Configuration can be loaded from files, strings, or dictionaries, and
14 | supports environment variable interpolation. The primary interaction point
15 | is usually the global `driver_config` instance.

2 | :synopsis: Interface wrappers for Firebird new API
3 |
4 | ==========================
5 | firebird.driver.interfaces
6 | ==========================
7 |
8 | This module contains interface wrappers for Firebird new API.
9 |
10 | .. important::
11 |
12 | 1. Firebird OO API interfaces use inheritance, i.e. they could be inherited from other
13 | interface. In fact, all interfaces returned by Firebird are inherited from `IVersioned`
14 | interface.
15 |
16 | 2. Firebird OO API interfaces are versioned. Any addition to particular interface
17 | increases its version number. Application developers are responsible to check the
18 | version of returned interface to verify that it supports methods they want to use.
19 |
20 | If you want to use Firebird OO API interfaces directly in you application, read next
21 | section very carefuly.
22 |
23 | In Python driver, interfaces are represented as instances of interface wrapper classes
24 | that expose the methods provided by particular Firebird interface version. The wrapper
25 | class hierarchy thus represent not only inheritabce between Firebird interfaces, but also
26 | between versions of particular Firebird interface.
27 |
28 | Because all interfaces returned by Firebird are inherited from `IVersioned` interface,
29 | all wrapper classes have `VERSION` class attribute that contain version number of wrapped
30 | interface.
31 |
32 | Each Firebird interface has it's "canonical" Python wrapper with coresponding name. For
33 | example interface `IService` has wrapper class `.iService`. However, if there are multiple
34 | public versions of Firebird interface, there are multiple wrapper classes for each published
35 | interface version (interim, non-public versions used during Firebird development are skipped).
36 | These wrapper classes have names based on their canonical name with suffix that represent
37 | the interface version they wrap. It means that canonical wrapper **always** represents
38 | the highest interface version.
39 |
40 | Whenever Firebird interface is returned from Firebird OO API call, it's wrapped to its
41 | Python wrapper class according to interface type and version. The Python driver ensures
42 | that correct wrapper class is used according to returned interface version.
43 |
44 | However, this architecture has several important consequences:
45 |
46 | 1. The interface wrapper classes may change between driver releases as new interface versions
47 | are introduced. For example, driver versions up to 1.5.2 had only canonical `.iService`
48 | (version 3), but in version 1.6.0 it was renamed to `.iService_v3`, new wrappers
49 | `.iService_v4` and (new canonical) `.iService` (version 5) were added.
50 | 2. Instead using `isinstance` to check interface versions, you should always use
51 | `VERSION` attribute on wrapper class instance.

36 | """firebird-driver - Driver Hooks
37 |
38 | This module defines specific hook points (events) within the firebird-driver
39 | lifecycle where custom functions can be registered and executed. These hooks
40 | allow for extending or modifying driver behavior, logging, or monitoring.
41 |
42 | Hooks are registered using `firebird.driver.add_hook()` or the `firebird.base.hooks.hook_manager`.
43 | The specific signature required for each hook function and the context in which
44 | it's called are documented within the driver methods that trigger these hooks
45 | (primarily in `firebird.driver.core`).
