How does SQL Server View the execution time of SQL statements?

In the SQL Server database, how can I view the execution time of SQL statements? This article will introduce you to the query method for your reference.

The following is a simple SQL statement execution time query method in SQL Server. It is calculated based on the time difference between the query time and the query time:

Declare @ begin_date datetime
Declare @ end_date datetime
Select @ begin_date = getdate ()
<Write your statement here...>
Select @ end_date = getdate ()
Select datediff (MS, @ begin_date, @ end_date) as 'time/millisecond'
 

2: The following method is comprehensive. The steps taken when each statement is executed are returned as a row set and are displayed in the form of a hierarchy tree.

Set statistics profile on
Set statistics Io on
Set statistics time on
