Hmm. "String nativeSQL(String sql) . . . converts the . . . JDBC SQL grammar into . . . the native form of the statement"

From the JavaDoc:
nativeSQL

String nativeSQL(String sql) throws SQLException

Converts the given SQL statement into the system's native SQL
grammar. A driver may convert the JDBC SQL grammar into its system's
native SQL grammar prior to sending it. This method returns the
native form of the statement that the driver would have sent.


Anybody here know what that's all about? Is there some unified JDBC SQL
standard that somehow homogenizes things like RRN in DB2/400, and LIMIT
in MySQL?

Also, does anybody know of a way, via a JDBC connection, to find out
(other than by trial-and-error) whether a given database system supports
things like RRN and LIMIT, and whether a given table has a primary key?
