schema
Merged revision 1527963 from trunk.
> CREATE TRIGGER doesn't detect all illegal references to SESSION schema
> ----------------------------------------------------------------------
>
> Key: DERBY-6357
> URL: https://issues.apache.org/jira/browse/DERBY-6357
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.10.1.1
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
> Attachments: d6357-1a.diff
>
>
> The reference manual's section on the DECLARE GLOBAL TEMPORARY TABLE
> statement says: Temporary tables cannot be referenced in a
> triggered-SQL-statement
> It detects most cases and reports:
> ERROR XCL51: The requested function can not reference tables in SESSION
> schema.
> However, some references are not detected if they are in a subquery. For
> example:
> ij version 10.10
> ij> connect 'jdbc:derby:memory:db;create=true';
> ij> declare global temporary table temptable(x int) not logged;
> 0 rows inserted/updated/deleted
> ij> create table t1(x int);
> 0 rows inserted/updated/deleted
> ij> create table t2(b boolean);
> 0 rows inserted/updated/deleted
> ij> create trigger tr1 after insert on t1 insert into t2 values exists(select
> * from session.temptable);
> 0 rows inserted/updated/deleted
> This CREATE TRIGGER statement should have raised an error.
