Causes an application to wait until notified of an event occurrence. Available in gpre.

EVENT WAIT request_name;
Argument Description

<request_name>

Application event handle declared in a previous EVENT INIT statement

Description: EVENT WAIT is the second step in the InterBase two-part synchronous event mechanism. After a program registers interest in an event, EVENT WAIT causes the process running the application to sleep until the event of interest occurs.

Examples: The following embedded SQL statements register an application event name and indicate the program is ready to receive notification when the event occurs:

EXEC SQL
EVENT INIT ORDER_WAIT EMPDB ('new_order');
EXEC SQL
EVENT WAIT ORDER_WAIT;
