The CURRENT TIMESTAMP special register specifies a timestamp that is based on a reading of the time-of-day clock when the SQL statement is executed at the application server. If this special register is used more than once within a single SQL statement, or used with CURRENT DATE or CURRENT TIME within a single statement, all values are based on a single clock reading.
Insert a row into the IN_TRAY table. The value of the RECEIVED column should be a timestamp that indicates when the row was inserted. The values for the other three columns come from the host variables SRC (char(8)), SUB (char(64)), and TXT (varchar(200)).
INSERT INTO IN_TRAY
VALUES (CURRENT TIMESTAMP, :SRC, :SUB, :TXT)
