Help With Cursor To Insert 100 Rows At A Time

Hi all,

Can one of you help me with using a cursor that would insert only 100 rows at a time from source table 1 to target table 2. I am not able to loop beyond the first 100 rows.

Here is what I have till now:


CREATE procedure Insert100RowsAtaTime
AS
SET NOCOUNT ON

declare @Col1 int
declare @Col2 char(9)
DECLARE @RETURNVALUE int
DECLARE @ERRORMESSAGETXT varchar(510)
DECLARE @ERRORNUM int
DECLARE @LOCALROWCOUNT int

declare Insert_Cur cursor local fast_forward
FOR
SELECT top 100 Col1,Col2 from Table1
WHERE Col1 not in ( SELECT Col1 /* Col1 is PK. This statement is used to prevent the same rows from being inserted in Table 2*/
from Table2)

set @RETURNVALUE = 0
set @ERRORNUM = 0

BEGIN

open Insert_Cur
fetch NEXT from Insert_Cur into @Col1, @Col2
while (@@FETCH_STATUS = 0)
insert into Table2 (Col1,Col2) select @Col1,@Col2

SELECT @ERRORNUM = @@ERROR, @LOCALROWCOUNT = @@ROWCOUNT
IF @ERRORNUM = 0
BEGIN
IF @LOCALROWCOUNT >= 1
BEGIN
SELECT @RETURNVALUE = 0
END
ELSE
BEGIN
SELECT @RETURNVALUE = 1
RAISERROR ('INSERT FAILS',16, 1)
END
END
ELSE
BEGIN
SELECT @ERRORMESSAGETXT = description FROM [master].[dbo].[sysmessages]
WHERE error = @@ERROR
RAISERROR (@ERRORMESSAGETXT, 16, 1)
SELECT @RETURNVALUE = 1
END

fetch NEXT from Insert_Cur into @Col1, @Col2
end

close Insert_Cur
deallocate Insert_Cur

RETURN @RETURNVALUE
END
