Hold cursors

When transaction logging is used, HCL Informix® generally closes all cursors and releases all locks when a transaction ends. In a multiuser environment, this behavior is not always desirable.

HCL Informix JDBC Driver had already implemented holdable cursor support with Informix extensions. Informix database servers (5.x, 7.x, SE, 8.x, 9.x, and 10.x, or later) support adding keywords WITH HOLD in the declaration of the cursor. Such a cursor is referred to as a hold cursor and is not closed at the end of a transaction.

HCL Informix JDBC Driver, in compliance with the JDBC 3.0 specifications, adds methods to JDBC interfaces to support holdable cursors.
