Oracle has varchar and varchar2 both ... <tfm> The VARCHAR2 subtypes below have the same range of values as their base type. For example, VARCHAR is just another name for VARCHAR2.
STRING VARCHAR You can use these subtypes for compatibility with ANSI/ISO and IBM types. Note: Currently, VARCHAR is synonymous with VARCHAR2. However, in future releases of PL/SQL, to accommodate emerging SQL standards, VARCHAR might become a separate datatype with different comparison semantics. So, it is a good idea to use VARCHAR2 rather than VARCHAR. </tfm> http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96624/03_types.htm#10824 HTH Raj -------------------------------------------------------------------------------- Rajendra dot Jamadagni at nospamespn dot com All Views expressed in this email are strictly personal.

True enough. I'd forgotten about COBOL. The semantics of COBOL's PIC X fields match up pretty closely (exactly?) to SQL CHAR fields. DW> My understanding is that VARCHAR2 is not even a SQL standard The keyword VARCHAR2 is not in the standard, but a variable-length type is. I think the standard uses CHARACTER VARYING, or something like that. I don't have time to look it up right now. DB2 uses VARCHAR, without the "2". I'm not sure why Oracle is so outspoken against that same keyword. I'd be interested in finding out.
