My payment details can be found here: https://p32929.github.io/SendMoney2Me/ 27 | 28 | ## Installation 29 | Add it in your root build.gradle at the end of repositories: 30 | ``` 31 | allprojects { 32 | repositories { 33 | maven { url 'https://jitpack.io' } 34 | } 35 | } 36 | ``` 37 | 38 | Add the dependency 39 | ``` 40 | dependencies { 41 | implementation 'com.github.p32929:AndroidEasySQL-Library:1.4.1' 42 | } 43 | ``` 44 | 45 | ## Basic Usage 46 | Steps to follow: 47 | * Initialize 48 | * Set Table Name (Not mandatory) 49 | * Add columns 50 | * Call done method 51 | 52 | After that you can do: 53 | * Add data 54 | * Read data 55 | * Edit data 56 | * Delete data 57 | * & so much more 58 | 59 | ## Code example 60 | ### Initialization, Set Table Name, Add columns, altogether: 61 | 62 | ``` 63 | EasyDB easyDB = EasyDB.init(this, "TEST") // TEST is the name of the DATABASE 64 | .setTableName("DEMO TABLE") // You can ignore this line if you want 65 | .addColumn("C1", "text") // Contrains like "text", "unique", "not null" are not case sensitive 66 | .addColumn("C2", "text", "unique") 67 | .addColumn("C3", "text", "unique", "not null") 68 | .doneTableColumn(); 69 | ``` 70 | 71 | or 72 | 73 | ``` 74 | EasyDB easyDB = EasyDB.init(this, "TEST") // "TEST" is the name of the DATABASE 75 | .setTableName("DEMO TABLE") // You can ignore this line if you want 76 | .addColumn(new Column("C1", "text", "unique")) // Contrains like "text", "unique", "not null" are not case sensitive 77 | .addColumn(new Column("C2", "text", "not null")) 78 | .addColumn(new Column("C3", "text")) 79 | .doneTableColumn(); 80 | ``` 81 | 82 | ** Saving the ```easyDB``` object into a variable will make easier to work with the database later. ** 83 | 84 | ** You don't have to add any primary key. The library does it by default (as ```ID``` column) ** 85 | 86 | ### Adding data: 87 | You can call the ```addData()``` in two ways: 88 | 89 | > addData(columnNumber, data) // ```columnNumber``` is an integer 90 | 91 | > addData(columnName, data) // ```columnName``` is a String 92 | 93 | ```data``` parameter in ```addData()``` can be either integer or string. After adding all the data, call ```doneDataAdding()``` method. 94 | 95 | Example: 96 | ``` 97 | boolean done = easyDB.addData(1, "Data1") 98 | .addData(2, "Data2") 99 | .addData(3, "Data3") 100 | .doneDataAdding(); 101 | ``` 102 | 103 | or 104 | 105 | ``` 106 | boolean done = easyDB.addData("C1", "Data1") 107 | .addData("C2", "Data2") 108 | .addData("C3", "Data3") 109 | .doneDataAdding(); 110 | ``` 111 | 112 | Thus, it will return a boolean value. 113 | ```True``` means data added successfully, 114 | ```False``` means data isn't added successfully. 115 | 116 | ### Get/Read All Data: 117 | To get all data as a ```Cursor``` object, call ```getAllData()``` or ```getAllDataOrderedBy()``` like this: 118 | 119 | ```Cursor res = easyDB.getAllData();``` 120 | 121 | or 122 | 123 | ```Cursor res = easyDB.getAllDataOrderedBy(columnNumber, ascendingOrDescending);``` 124 | 125 | ```ascendingOrDescending``` parameter in ```getAllDataOrderedBy()``` is a boolean value. To get all data in ascending order pass ```true```, or to get all data in descending order pass ```false``` as the parameter. 126 | 127 | Later use a while loop like this: 128 | 129 | ``` 130 | while (res.moveToNext()) { 131 | // Your code here 132 | } 133 | ``` 134 | 135 | To get an integer from ```res``` call ```getInt(columnIndex)``` and to get a String call ```getString(columnIndex)``` like this: 136 | ``` 137 | int anIntegerVariable = res.getInt(columnIndex); 138 | String aStringVariable = res.getString(columnIndex); 139 | ``` 140 | 141 | here ```columnIndex``` is an integer, starts from 0. 142 | 143 | Example: 144 | 145 | ``` 146 | Cursor res = easyDB.getAllData(); 147 | while (res.moveToNext()) { 148 | int anIntegerVariable = res.getInt(columnIndex); 149 | String aStringVariable = res.getString(columnIndex); 150 | } 151 | ``` 152 | 153 | or 154 | 155 | ``` 156 | Cursor res = easyDB.getAllDataOrderedBy(columnNumber, false); 157 | while (res.moveToNext()) { 158 | int anIntegerVariable = res.getInt(columnIndex); 159 | String aStringVariable = res.getString(columnIndex); 160 | } 161 | ``` 162 | 163 | 164 | ### Get/Read one row data: 165 | To get data from a row, call ```getOneRowData(rowID)```. It will return the data as a Cursor object. You can then retrieve each column data from the cursor. 166 | Example: 167 | ``` 168 | Cursor res = easyDB.getOneRowData(1); 169 | if (res != null) { 170 | res.moveToFirst(); // Because here's only one row data 171 | String ID = res.getString(0); // Column 0 is the ID column 172 | String c1 = res.getString(1); 173 | String c2 = res.getString(2); 174 | } 175 | ``` 176 | 177 | ### Get/Read/Search one/multiple row data by matching a column data: 178 | To get data from one/multiple rows by matching data with a column, call ```searchInColumn(columnNumber, valueToSearch, limit)``` or ```searchInColumn(columnName, valueToSearch, limit)``` 179 | example: 180 | ``` 181 | Cursor res = easyDB.searchInColumn(1, "data", 1); // Here we passed limit = 1. Thus it will return only one row data with the matched column value 182 | if (res != null) { 183 | res.moveToFirst(); // Because here's only one row data 184 | String ID = res.getString(0); // Column 0 is the ID column 185 | String c1 = res.getString(1); 186 | String c2 = res.getString(2); 187 | } 188 | ``` 189 | 190 | or 191 | 192 | ``` 193 | Cursor res = easyDB.searchInColumn("ID", "data", -1); // Here we passed limit = -1. Thus it will return all the rows with the matched column values 194 | if (res != null) { 195 | while (res.moveToNext()) { 196 | String ID = res.getString(0); // Column 0 is the ID column 197 | String c1 = res.getString(1); 198 | String c2 = res.getString(2); 199 | } 200 | } 201 | ``` 202 | 203 | > Please DO NOT pass ```limit = 0``` as the parameter 204 | 205 | ### Match data from multiple columns: 206 | To check if some values exist or not in the database, first call ```getAllColumns()``` to get all the column names like this: 207 | 208 | ```String columns[] = easyDB.getAllColumns();``` 209 | 210 | Now, You may create an array of ```String``` defining which columns you want to match with some values, like this: 211 | 212 | ``` 213 | String columnsToMatch[] = new String[]{columns[1], columns[2]}; 214 | ``` 215 | And an array of values(String) you want to match, like this: 216 | 217 | ``` 218 | String valuesToMatch[] = new String[]{valueToSearchInColumn1, valueToSearchInColumn2}; 219 | ``` 220 | 221 | Now call ```matchColumns()``` like this: 222 | 223 | ```boolean matched = easyDB.matchColumns(columnsToMatch, valuesToMatch);``` 224 | 225 | Thus, it will return a boolean value. So, you can know if your given values are matched or not. 226 | 227 | ** Creating these two array variables(```columnsToMatch``` & ```valuesToMatch```) will make it easier to pass them into ```matchColumns()``` method. ** 228 | 229 | ### Update / Edit data: 230 | To update / Edit, call ```updateData(columnNumber, data)``` method. 231 | Example: 232 | ``` 233 | boolean updated = easyDB.updateData(1, "UpdatedData1") 234 | .updateData(2, "UpdatedData2") 235 | .updateData(3, "UpdatedData3") 236 | .rowID(id); 237 | ``` 238 | 239 | UpdatedData can be either integer or String. 240 | Thus, it will return a boolean value. So, you can know if your data is updated or not... 241 | 242 | ### Delete data: 243 | To delete a row data, call ```deleteRow(rowId)``` like this: 244 | 245 | ```boolean deleted = easyDB.deleteRow(rowId);``` 246 | 247 | or 248 | 249 | ```boolean deleted = easyDB.deleteRow(columnNumber, valueToMatch)``` 250 | 251 | or 252 | 253 | ```boolean deleted = easyDB.deleteRow(columnName, valueToMatch)``` 254 | 255 | Thus, it will return a boolean value. So, you can know if your data is updated or not... 256 | 257 | ### Delete all data from the Table: 258 | To delete the table and its all data, call ```deleteAllDataFromTable``` like this: 259 | 260 | ```easyDB.deleteAllDataFromTable();``` 261 | 262 | Hope you'll enjoy using the library :) 263 | 264 | > Thanks 265 | 266 | ## License: 267 | ``` 268 | MIT License 269 | 270 | Copyright (c) 2018 Fayaz Bin Salam 271 | 272 | Permission is hereby granted, free of charge, to any person obtaining a copy 273 | of this software and associated documentation files (the "Software"), to deal 274 | in the Software without restriction, including without limitation the rights 275 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 276 | copies of the Software, and to permit persons to whom the Software is 277 | furnished to do so, subject to the following conditions: 278 | 279 | The above copyright notice and this permission notice shall be included in all 280 | copies or substantial portions of the Software. 281 | 282 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 283 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 284 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
