Why not define it as a text column? No. The problem is axactly what the message says: A quoted string exceeds 256 bytes. This is a message from your tool. Define a variable LIKE the column or as CHAR(4096). Then assign your text to this variable in segments of upto 256 chars at a time, such as: LET var = "first string.....", "second string.....", "etc....." Then use the variable in your INSERT statement. Hope that helps, -- Mark. +-------------------------------------------------------------------------+ |Mark D.
