Ah...well I'm familiar with FOO but I didn't know about FOOBAR...must be a programmer joke....sorry I didn't get it the first time...:)

He is referring to FOOBAR which is a reference often used with perl and probably most of the older programming languages. _____ From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] On Behalf Of L.

I have wanted to create something like this for a while... so I just wrote this SQL Server 2000 function that returns the checksum of an attachment field (actually any field of Image data type. The current and new values could be compared to see if it changed. You can also use this to find duplicates in the attachment fields in your system. CREATE FUNCTION dbo.udf_GetImageChecksum ( @ImageField IMAGE ) RETURNS INT AS BEGIN DECLARE @Len BIGINT, @Pos BIGINT, @CheckSum VARCHAR(8000) SET @Len = DATALENGTH(@ImageField) SET @Pos = 1 SET @CheckSum = '' WHILE @Pos < @Len BEGIN SET @CheckSum = @CheckSum + CONVERT(VARCHAR, BINARY_CHECKSUM(SUBSTRING(@ImageField, @Pos, 8000))) IF LEN(@CheckSum) > 7900 SET @CheckSum = CONVERT(VARCHAR, CHECKSUM(@CheckSum)) SET @Pos = @Pos + 8000 END RETURN CHECKSUM(@CheckSum) END In a Set Fields SQL command: SELECT dbo.udf_GetImageChecksum(c536880912) FROM b611c536880912 WHERE entryId = 'ATTACH000016929' HTH someone.

The "value" contains the file size in bytes, the compressed size in the DB and the full filename on the client. Also note that user cannot change the attachment from the attachment field without re-attaching it. Just changing the attachment (open->edit->save) doesn't update the DB, it only updates the local temporary copy of the file.

Remedy stores the attachments in the following way <number of characters>,<no of bytes>(i am sure. but it might bytes),<filename with extenstion>.
