Managing Data Collection Using Transact-SQL

The data collector provides an extensive collection of stored procedures that you can use to perform any data collection task. In addition, there are functions and views that you can use to get configuration data for the msdb and management data warehouse databases, execution log data, and data that is stored in the management data warehouse.

You can use the stored procedures, functions, and views that are provided to create your own end-to-end data collection scenarios.

Important

Unlike regular stored procedures, the data collector stored procedures use strictly typed parameters and do not support automatic data type conversion. If these parameters are not called with the correct input parameter data types, as specified in the argument description, the stored procedure returns an error.

You can use SQL Server Management Studio to create and execute the provided code samples. For more information, see Using Object Explorer. As an alternative you can create the query in any editor and save it in a text file that has a .sql file name extension. You can execute the query from the Windows command prompt using the sqlcmd utility. For more information, see Using the sqlcmd Utility.
