Hi,
I've a column Event_Desc(255)nvarchar in a table. If I insert a record in it through stored procesure which is more than 255 chars, it gives error.
Can any one give me the code in stored proc format which will check if length of event_desc entered by user not more than 255 & that if it is it'll just accept first 255 chars & insert it into database.
I'm using SQL Server 2000.
Here is my existing stored proc:
CREATE PROCEDURE [dbo].[AddSystemEvent]
(
@ScannerID As Int,
@TimeDate DateTime,
@EventID As Int,
@EventDesc NVarchar(256)
)
AS
Begin
Insert Into tb_system_event
(Scanner_ID, Time_Date, Event_ID, Event_Description)
Values (@ScannerID, @TimeDate, @EventID, @EventDesc)
End
Appreciate any help!!!!
Thanks!!!

maybe i'm just misreading it, but you want to insert just 255 chars right?

CREATE PROCEDURE [dbo].[AddSystemEvent]

(

@ScannerID As Int,

@TimeDate DateTime,

@EventID As Int,

@EventDesc NVarchar(256)

)

AS

Begin

Insert Into tb_system_event

(Scanner_ID, Time_Date, Event_ID, Event_Description)

Values (@ScannerID, @TimeDate, @EventID, LEFT(@EventDesc,255))

End

Replace @EventDesc NVarchar(256) with @EventDesc NVarchar(255). If you limit the input to only 255 character, you should not be requiring any extra functions.

from Query analyzer or SQL 2005 Management Studio:

exec AddSystemEvent 12,'06/09/2008',-21,'Some Bad Event Occured that probably should not have.'

note the scanner id example i put in an arbitrary number of 12, and did something similar with The EventId (-21)
