> I'm having problems will calling functions from within a trigger.
> The problem seems to be with the outer function call (FLOOR() in this case, but it also happens with other functions). It works fine in the SELECT statement, but when used in the trigger it throws a ArrayIndexOutOfBoundsException.
> Remove the FLOOR() part from the trigger and it works fine.
> {code}
> -- create source table and some data
> CREATE TABLE foo (name VARCHAR(20), val DOUBLE);
> INSERT INTO foo (name, val) VALUES ('A', 10), ('A', 20), ('B', 30), ('C', 40);
> -- calling the function works fine here
> SELECT name, FLOOR(AVG(LOG10(val))), COUNT(*)
> FROM foo
> GROUP BY name;
> -- create target table for trigger
> CREATE TABLE summary (name VARCHAR(20), aver DOUBLE, size INT);
> -- create the trigger
> CREATE TRIGGER trg_foo AFTER INSERT ON foo
> REFERENCING NEW TABLE AS changed FOR EACH STATEMENT MODE DB2SQL
> INSERT INTO summary (name, aver, size)
> SELECT name, FLOOR(AVG(LOG10(val))), COUNT(*)
> FROM changed
> GROUP BY name;
> -- insert rows to cause trigger to fire
> INSERT INTO foo (name, val) VALUES ('A', 10), ('A', 20), ('B', 30), ('C', 40);
> SELECT * FROM foo;
> SELECT * FROM summary;
> {code}
