Using Cursor in SQL

In this post i will show how to use a cursor in SQL. Cursor works on a row by row basis.

In the below example for cursor i will print the name of the employees from the employee table using cursor.


DECLARE cur CURSOR
FOR
SELECT empname
FROM empDataDetails

DECLARE @name VARCHAR(1000)

OPEN cur 

FETCH NEXT
FROM cur
INTO @name

WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @name

FETCH NEXT
FROM cur
INTO @name
END

CLOSE cur

DEALLOCATE cur
