Comply with SQLJ
The syntax of Java™ UDRs
that the HCL Informix® database
server supports usually follows the SQLJ specification. Where syntactic
differences and missing features occur, the differences are mostly
due to differences between Informix SQL
and the SQL-3 standards. The following table summarizes the level
of SQLJ compliance.
