> If a trigger action references a transition variable and has whitespace around the period sign that separates the transition variable name from the column name, it fails with a syntax error.
> For example:
> {noformat}
> ij> create table t1(x int);
> 0 rows inserted/updated/deleted
> ij> create table t2(x int);
> 0 rows inserted/updated/deleted
> ij> --fails
> create trigger tr1 after insert on t1 referencing new as new
> for each row insert into t1 select x from t2 where x = new . x;
> ERROR 42X01: Syntax error: Encountered "x" at line 1, column 150.
> Issue the 'help' command for general information on IJ command syntax.
> Any unrecognized commands are treated as potential SQL commands and executed directly.
> Consult your DBMS server reference documentation for details of the SQL syntax supported by your server.
> ij> --succeeds
> create trigger tr2 after insert on t1 referencing new as new
> for each row insert into t1 select x from t2 where x = new.x;
> 0 rows inserted/updated/deleted
> {noformat}
> The only difference between the failing trigger definition and the successful one, is that the former says "new . x" and the latter "new.x".
> Both should succeed.
