Introduction:
ROWCOUNT uses to stop processing the query after the
specified number of rows is returned means its returned rows by query as Top
keyword in sql.
Data for Query:
SELECT Id,Name,SALARY FROM EMPLOYEE
Use Top Keyword:
Query uses top keyword to return specified number of rows.
SELECT TOP
5 Id,Name,SALARY
FROM EMPLOYEE
Use RowCOUNT:
DECLARE
@NoOfRows INT =
5
SET ROWCOUNT @NoOfRows
SELECT Id,Name,SALARY FROM EMPLOYEE
Here ROWCOUNT uses to stop processing the query after the
specified number of rows is returned. When we use more than one select statement then both
select statement will work according to ROWCOUNT means both select statement
will have effect of ROWCOUNT and both select statement will return fix according
to ROWCOUNT.
Use @@ROWCOUNT:
It returns number of affected rows by last statement but it does not return this value to client.
DECLARE
@NoOfRows INT =
5
SET ROWCOUNT @NoOfRows
SELECT Id,Name,SALARY FROM EMPLOYEE
SELECT @@ROWCOUNT AS [Number Of Rows]
