Tracks object history in SQL Servers.
This is a set of scripts which allow you to track changes in most system objects across all databases in a SQL Server installation.
Scripts have been tested on SQL Server 2008 R2 only, but they should work on versions as earlier as SQL Server 2005 and later with few modifications.
| Type | Description |
|---|---|
| C | CHECK constraint |
| D | DEFAULT (constraint or stand-alone) |
| F | FOREIGN KEY constraint |
| FN | SQL scalar function |
| IF | SQL inline table-valued function |
| P | SQL Stored Procedure |
| PK | PRIMARY KEY constraint |
| TF | SQL table-valued-function |
| U | Table (user-defined) |
| UQ | UNIQUE constraint |
| V | View |
| IX | Index (not a SQL Server object type) |
| Type | Description |
|---|---|
| AF | Aggregate function (CLR) |
| FS | Assembly (CLR) scalar-function |
| FT | Assembly (CLR) table-valued function |
| IT | Internal table |
| PC | Assembly (CLR) stored-procedure |
| PG | Plan guide |
| R | Rule (old-style, stand-alone) |
| RF | Replication-filter-procedure |
| S | System base table |
| SN | Synonym |
| SQ | Service queue |
| TA | Assembly (CLR) DML trigger |
| TR | SQL DML trigger |
| X | Extended stored procedure |
- prereq_DefaultTraceEnabled.sql : Helps verifying and enabling default trace.
- install.sql : Creates table ObjectHistories, stored procedures DatabaseObjectGetDefinition and ObjectHistoriesPopulate
- init_ObjectHistories.sql : Initializes ObjectHistories table with all database object descriptions (may take a while)
- schedule_ObjectHistoriesPopulate.sql : Sample for scheduling the execution of ObjectHistoriesPopulate hourly
Tracking relies on 'default trace enabled' advanced setting being enabled.
If your server's default trace gets corrupted, you will lose changes until it clears out.
If an object is changed more than once between two scheduled updates, you will lose the changes that happened in between.
- Make sure you have default trace enabled. File prereq_DefaultTraceEnabled.sql should help.
- Open file install.sql
- Edit the database ([_Maintenance] by default) and schema ([dbo] by default) you want to install on
- Run
- Run init_ObjectHistories.sql if you would like to prepopulate [ObjectHistories] table with all database's object descriptions (may take a while)
- You will have to setup a scheduled task to run [ObjectHistoriesPopulate] every hour. There is a sample on schedule_ObjectHistoriesPopulate.sql
- Add more definitions (stored procedure [DatabaseObjectGetDefinition])
- Build create scripts instead of listing object details (stored procedure [DatabaseObjectGetDefinition])
- Test and make code compatible in SQL Server 2005 and later
