• Component/s: SQL
• Affects Version/s: 10.0.2.0

Description

Two triggers on same table may lead to self-recursion:

ij> create table t3(i integer primary key, j integer, t timestamp);
0 rows inserted/updated/deleted
ij> create trigger tr3i after insert on t3 referencing new as new for each row mode db2sql update t3 set t = current_timestamp where i = new.i;
0 rows inserted/updated/deleted
ij> insert into t3 values (1, 1, NULL);
1 row inserted/updated/deleted
ij> create trigger tr3u after update on t3 referencing old as old for each row mode db2sql update t3 set t = current_timestamp where i = old.i;
0 rows inserted/updated/deleted
ij> insert into t3 values (2, 1, NULL);
ERROR 54038: Maximum depth of nested triggers was exceeded.
ij> update t3 set j=j+1;
1 row inserted/updated/deleted
ij> create trigger tr3u2 after update on t3 referencing old as old for each row mode db2sql update t3 set j = 0 where i = old.i and j > 2;
0 rows inserted/updated/deleted
ij> update t3 set j=j+1;
