#
|
|
# When both a main database table and a TEMP table have the same name,
|
|
# and a main database trigge is created on the main table, the trigger
|
|
# is incorrectly bound to the TEMP table. For example:
|
|
#
|
|
# CREATE TABLE t1(x);
|
|
# CREATE TEMP TABLE t1(x);
|
|
# CREATE TABLE t2(z);
|
|
# CREATE TRIGGER main.r1 AFTER INSERT ON t1 BEGIN
|
|
# INSERT INTO t2 VALUES(10000 + new.x);
|
|
# END;
|
|
# INSERT INTO main.t1 VALUES(3);
|
|
# INSERT INTO temp.t1 VALUES(4);
|
|
# SELECT * FROM t2;
|
|
#
|
|
# The r1 trigger fires when the value 4 is inserted into the temp.t1
|
|
# table, rather than when value 3 is inserted into main.t1.

# CREATE TRIGGER xyz.trig BEFORE UPDATE ON xyz.tab BEGIN ...

# But a long-standing bug does allow it. And the "xyz.tab" slips into
