hi! we have sybase (ASE/11.9.2.5 set on NT4).i have a stored proc where i am retrieving two sets of values from a table and inserting into a temp table. both the values and the destination field are of datatype "image". based on certain conditions, i need to concatenate the two values and populate the destination field. when i try to concatenate, i get an error "the once aggregate operation cannot take a image datatype as an argument". can someone advise how i can concatenate / update fields with "image"?

thx in advance

You cannot issue distinct or group by statements on image datatypes.
You will need to use writetext function to deal with image datatype.

See example,

Sort of saying the same thing in a different way:

You can't do that in a stored procedure.  If you want to manipulate IMAGE data, your best option is probably to write a simple open client application that can read in the two IMAGE values, concatentate them in a buffer on the client side, then insert the resulting value using writetext.

Bret,

I think writetext can be used with stored procedure. Need to get text pointer and then loop thru to insert.

you can't concatenate image data type, however as BRET suggested you can use WRITETEXT
