Java database connectivity and embedded SQL for Java

Db2 provides two standards-based Java™ programming APIs: Java Database Connectivity (JDBC) and embedded SQL for Java (SQL/OLB or SQLJ). Both can be used to create Java applications and applets that access Db2.

Static SQL cannot be used by JDBC. SQLJ applications use JDBC as a foundation for such tasks as connecting to databases and handling SQL errors, but can contain embedded static SQL statements in the SQLJ source files. An SQLJ file has to be translated with the SQLJ translator before the resulting Java source code can be compiled.
