Error handling means if our stored procedure generates any error while running,we can handle that error.So that it will not show the error.

For eg.

insert into emp(sno,name,age) values(10,'Vasanth',26);

Consider field "sno" is primary key.When we are giving duplicate input to the sno it will show the error.

If you dont want to show the error ,you can capture the error and display as below.

BEGIN TRY
insert into emp(sno,name,age) values(10,'Vasanth',26);

END TRY

BEGIN CATCH
SELECT @err = @@error
IF @err <> 0
BEGIN
RETURN @err
END
END CATCH

Here in this case,it will capture the error and display.
