Hi. We are using Microsoft SQL Server 2000. The code below does work to update an image field in the Shipper table with the corresponding serial numbers, but when I tried a long list of serial numbers, I counted only 50 characters entered into the field.

What can I do to improve the trigger so all of the information can be entered?

Thanks.
CREATE   TRIGGER ABC_UPDATE_PACK_LIST_SN ON [dbo].[SHIPPER_LINE] 

FOR INSERT 

AS
 

                      DECLARE @ROWID		VARCHAR(15) 

	DECLARE @CUST_ORDER_ID	VARCHAR(10)

	DECLARE @CUST_ORDER_LINE	VARCHAR(2)

	DECLARE @APG_SERIAL_NUM	 VARCHAR(50)	

	DECLARE @LONG_DESC		VARCHAR(50)

	DECLARE @PACKLIST_ID		VARCHAR(10)

	DECLARE @PACKLIST_LINE	VARCHAR(4)

	

	

	SELECT @ROWID = I.ROWID, @CUST_ORDER_ID = I.CUST_ORDER_ID,

		@CUST_ORDER_LINE = I.CUST_ORDER_LINE_NO,

		@PACKLIST_ID = I.PACKLIST_ID, 

		@PACKLIST_LINE = I.LINE_NO

		FROM INSERTED I
 

	SELECT @ABC_SERIAL_NUM=ABCDE.dbo.ABC_SERIAL_NUMBERS.SERIAL_NUMBERS

	        FROM ABCDE.dbo.ABC_SERIAL_NUMBERS

		WHERE (@CUST_ORDER_ID = CUST_ORDER) AND (@CUST_ORDER_LINE = CUST_ORDER_LINE)
 

	IF @ABC_SERIAL_NUM IS NOT NULL
 

		BEGIN

		

		UPDATE SHIPPER_LINE SET LONG_DESCRIPTION = @ABC_SERIAL_NUM WHERE PACKLIST_ID = @PACKLIST_ID and LINE_NO = @PACKLIST_LINE
 

		END

I presume the problem is because of the variable in the code defined as VARCHAR(50) ?

apart from that, change the code like this:
CREATE   TRIGGER ABC_UPDATE_PACK_LIST_SN ON [dbo].[SHIPPER_LINE] 
FOR INSERT 
AS 
  UPDATE sl 
     SET LONG_DESCRIPTION = sn.SERIAL_NUMBERS
    FROM INSERTED i
    JOIN ABCDE.dbo.ABC_SERIAL_NUMBERS sn
      ON sn.CUST_ORDER = i.CUST_ORDER_ID
     AND sn.CUST_ORDER_LINE = i.CUST_ORDER_LINE_NO
    JOIN SHIPPER_LINE sl 
      ON sl.PACKLIST_ID = i.PACKLIST_ID
     AND sl.LINE_NO = i.LINE_NO
   WHERE sn.SERIAL_NUMBERS IS NOT NULL

Thanks. When I increased the field to VARCHAR(8000) I could see the rest of the text.
