functions](https://SQLsharp.com/) (by Sql Quantum Lift) 10 | 11 | The common language runtime (CLR) is the heart of the Microsoft .NET Framework and provides the execution environment for all .NET Framework code. Code that runs within the CLR is referred to as managed code. The CLR provides various functions and services required for program execution, including just-in-time (JIT) compilation, allocating and managing memory, enforcing type safety, exception handling, thread management, and security. 12 | 13 | With the CLR hosted in Microsoft SQL Server (called CLR integration), you can author stored procedures, triggers, user-defined functions, user-defined types, and user-defined aggregates in managed code. Because managed code compiles to native code prior to execution, you can achieve significant performance increases in some scenarios. 14 | 15 | Enabling CLR Integration: 16 | 17 | ```tsql 18 | EXEC sp_configure 'clr enabled', 1; 19 | RECONFIGURE; 20 | GO 21 | ``` 22 | -------------------------------------------------------------------------------- /CLR/Regex/Fill_Factor/InstallRegex.sql: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/CLR/Regex/Fill_Factor/InstallRegex.sql -------------------------------------------------------------------------------- /CLR/Regex/SqlRegularExpressions_SQLServerProject_QuickDeployment.zip: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/CLR/Regex/SqlRegularExpressions_SQLServerProject_QuickDeployment.zip -------------------------------------------------------------------------------- /Errors/Backup/Be aware of 701 error if you use memory optimized table variable in a loop.maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/Be aware of 701 error if you use memory optimized table variable in a loop.maff -------------------------------------------------------------------------------- /Errors/Backup/CREATE DATABASE – I’ve not seen that before..maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/CREATE DATABASE – I’ve not seen that before..maff -------------------------------------------------------------------------------- /Errors/Backup/Case study Troubleshooting Doomed Transactions.maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/Case study Troubleshooting Doomed Transactions.maff -------------------------------------------------------------------------------- /Errors/Backup/Compressed backup errors and TF 3042.maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/Compressed backup errors and TF 3042.maff -------------------------------------------------------------------------------- /Errors/Backup/Nuance of datetime data type in SQL Server.maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/Nuance of datetime data type in SQL Server.maff -------------------------------------------------------------------------------- /Errors/Backup/SQL SERVER - Disabling 15000 Partitions (15k).maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/SQL SERVER - Disabling 15000 Partitions (15k).maff -------------------------------------------------------------------------------- /Errors/Backup/SQL SERVER - FIX Error Msg 8672 - The MERGE Statement Attempted to UPDATE or DELETE the Same Row More Than Once.maff: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Errors/Backup/SQL SERVER - FIX Error Msg 8672 - The MERGE Statement Attempted to UPDATE or DELETE the Same Row More Than Once.maff -------------------------------------------------------------------------------- /Errors/Backup/SQL SERVER - FIX Error 913, Severity 16 - Could Not Find Database ID 3.

Also, the purge is "smart" and will not cause blocking and concurrency problems on instances with many, frequent SQL Agent jobs. Includes tsqlt unit tests. 9 | 10 | `seeddata.sql` is the only file that should need to be customized. You place your jobs and categories and their custom retention settings here. 11 | 12 | `DBA_sysjobhistory_config_tbl.sql` builds the table that handles the custom sysjobhistory retention configuration. 13 | 14 | `DBA_sysjobhistory_driver.sql` configures SQL Agent for unlimited history retention, since we'll be handling that now. It then examines each job in turn and runs `DBA_sp_jobhistory_row_limiter` to retain the custom settings for this job/category. This procedure should be scheduled to run every day (or so, depending on your requirements). 15 | 16 | `DBA_sp_jobhistory_row_limiter.sql` is more or less a copy of MS-provided sp_jobhistory_row_limiter with our custom logic. 17 | 18 | `DBA_sysjobhistory_driver_Tests.sql` is the tsqlt unit tests for this feature. 19 | -------------------------------------------------------------------------------- /Solution/SysJobHistory/seeddata.sql: -------------------------------------------------------------------------------- 1 | IF NOT EXISTS (select * from DBA_PM_sysjobhistory_config) 2 | BEGIN 3 | --insert base seed data, but only if this is the first run of SFU installer 4 | INSERT INTO DBA_sysjobhistory_config VALUES (NULL,'ETL',1,90) 5 | INSERT INTO DBA_sysjobhistory_config VALUES ('(default)','(default)',3,90) 6 | INSERT INTO DBA_sysjobhistory_config VALUES (NULL,'SFU TOOL',1,90) 7 | END; 8 | -------------------------------------------------------------------------------- /Solution/dbWarden/README.md: -------------------------------------------------------------------------------- 1 | # Microsoft SQL Server dbWarden Solution 2 | 3 | Original link: http://www.sqlservercentral.com/articles/Monitoring/98106/ 4 | Author: Michael Rounds 5 | 6 | This script creates a dbWarden database and all objects necessary to setup a database monitoring and alerting solution that notifies via email/texting. 7 | -------------------------------------------------------------------------------- /Stored_Procedure/Recover_Deleted_Data_Proc.sql: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Stored_Procedure/Recover_Deleted_Data_Proc.sql -------------------------------------------------------------------------------- /Stored_Procedure/dbo.sp_Defrag_Indexes.sql: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/exajobs/SQL-server-collection/79c63e7fe83e8f9b80fd0c15e641e56b7c996b27/Stored_Procedure/dbo.sp_Defrag_Indexes.sql -------------------------------------------------------------------------------- /Stored_Procedure/dbo.sp_Example_RegisterAssembly_PDFCLR.sql: -------------------------------------------------------------------------------- 1 | CREATE PROCEDURE dbo.spExample_RegisterAssembly_PDFCLR 2 | AS 3 | BEGIN 4 | DECLARE @FilePath varchar(1024) 5 | SET @FilePath = 'c:\ServerEnvironment\' 6 | 7 | CREATE TABLE #References (AssemblyName sysname, FQFileName varchar(1024)) 8 | INSERT INTO #References (AssemblyName, FQFileName) VALUES ('System.Drawing', 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll') 9 | INSERT INTO #References (AssemblyName, FQFileName) VALUES ('itextsharp', @FilePath + 'itextsharp.dll') 10 | 11 | DECLARE @DropWrapperSQL varchar(MAX) 12 | SET @DropWrapperSQL = ' 13 | IF OBJECT_ID(''dbo.udfRenderPDF'') IS NOT NULL BEGIN 14 | DROP FUNCTION dbo.udfRenderPDF; 15 | END 16 | ' 17 | 18 | DECLARE @CreateWrapperSQL varchar(MAX) 19 | SET @CreateWrapperSQL = ' 20 | CREATE FUNCTION [dbo].[udfRenderPDF]( 21 | @TemplatePDF varbinary(MAX), 22 | @FieldsXML xml 23 | ) 24 | RETURNS [varbinary](max) WITH EXECUTE AS CALLER 25 | AS 26 | EXTERNAL NAME [PDFCLR].[Functions].[RenderPDF] 27 | ' 28 | 29 | --C# Source Code. 30 | --Paste CLR source in below.
