SET STATISTICS TIME (Transact-SQL)

Displays the number of milliseconds required to parse, compile, and execute each statement.

Topic link icon Transact-SQL Syntax Conventions


SET STATISTICS TIME { ON | OFF }

When SET STATISTICS TIME is ON, the time statistics for a statement are displayed. When OFF, the time statistics are not displayed.

The setting of SET STATISTICS TIME is set at execute or run time and not at parse time.

Microsoft SQL Server is unable to provide accurate statistics in fiber mode, which is activated when you enable the lightweight pooling configuration option.

The cpu column in the sysprocesses table is only updated when a query executes with SET STATISTICS TIME ON. When SET STATISTICS TIME is OFF, 0 is returned.

ON and OFF settings also affect the CPU column in the Process Info View for Current Activity in SQL Server Management Studio.

To use SET STATISTICS TIME, users must have the appropriate permissions to execute the Transact-SQL statement. The SHOWPLAN permission is not required.

For more information, see Showplan Security.

This example shows the server execution, parse, and compile times.

USE AdventureWorks;
GO       
SET STATISTICS TIME ON
GO
SELECT * 
FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;
GO
SET STATISTICS TIME OFF;
GO

Here is the result set:

SQL Server parse and compile time: 
   CPU time = 0 ms, elapsed time = 1 ms.
SQL Server parse and compile time: 
   CPU time = 0 ms, elapsed time = 1 ms.

(269 row(s) affected)

SQL Server Execution Times:
   CPU time = 0 ms,  elapsed time = 2 ms.
SQL Server parse and compile time: 
   CPU time = 0 ms, elapsed time = 1 ms.
