Calculate Execution Time of a SQL Query

Measure the time it takes to execute a t-sql query

One simplistic approach to measuring the "elapsed time" between events is to just grab the current date and time.

In SQL Server Management Studio

SELECT GETDATE();
SELECT /* query one */ 1 ;
SELECT GETDATE();
SELECT /* query two */ 2 ;
SELECT GETDATE();

To calculate elapsed times, you could grab those date values into variables, and use the DATEDIFF function:

DECLARE @t1 DATETIME;
DECLARE @t2 DATETIME;

SET @t1 = GETDATE();
SELECT /* query one */ 1 ;
SET @t2 = GETDATE();
SELECT DATEDIFF(millisecond,@t1,@t2) AS elapsed_ms;

SET @t1 = GETDATE();
SELECT /* query two */ 2 ;
SET @t2 = GETDATE();
SELECT DATEDIFF(millisecond,@t1,@t2) AS elapsed_ms;

That's just one approach. You can also get elapsed times for queries using SQL Profiler.

Calculate execution time of a SQL query?

We monitor this from the application code, just to include the time required to establish/close the connection and transmit data across the network. It's pretty straight-forward...

Dim Duration as TimeSpan
Dim StartTime as DateTime = DateTime.Now

'Call the database here and execute your SQL statement

Duration = DateTime.Now.Subtract(StartTime)
Console.WriteLine(String.Format("Query took {0} seconds", Duration.TotalSeconds.ToString()))
Console.ReadLine()

How to calculate a MSSQL query execution time using python

toc = time()
print toc - tic

SQL Server Management Studio, how to get execution time down to milliseconds

I was struggling with that until i found this...

http://blog.sqlauthority.com/2009/10/01/sql-server-sql-server-management-studio-and-client-statistics/

Also, if you open the Properties window you may find some magical "Connection elapsed time" that may give you some execution time...
Hope it helps...

How can I get the execution time of an SQL query using MySQL Connector in Python?

Just calculate the time it takes to complete the query.

from time import time

# your code here

tic = time()
cursor.execute("select * from db.clients")
toc = time()
print toc - tic

Calculate Teradata Query Execution Time

Years ago the datataype for the timestamps in DBQL changed from TIMESTAMP(2) to TIMESTAMP(6), now when you try to get SECOND(2) in your result it overflows. To fix this either use SECOND(6) or ``SECOND`.

Btw, depending on your release, you'll find ElapsedTime & DelayTime pre-calculated in dbc.QryLogV.
