Description

If a reference to a transition table in a statement trigger has a correlation name, and that correlation name is equal to the name of the transition table, the CREATE TRIGGER statement fails with a syntax error.

To reproduce:

ij version 10.10
ij> connect 'jdbc:derby:db;create=true';
ij> create table t1(x int);
0 rows inserted/updated/deleted
ij> create table t2(x int);
0 rows inserted/updated/deleted
ij> create trigger tr1 after insert on t1 referencing new table as n insert into t2 select x from n as n;
ERROR 42X01: Syntax error: Encountered "as" at line 1, column 89.
Issue the 'help' command for general information on IJ command syntax.
Any unrecognized commands are treated as potential SQL commands and executed directly.
