> dblook doesn't qualify identifiers in the trigger action if they weren't explicitly qualified
in the original CREATE TRIGGER statement.
> Example:
> ij version 10.10
> ij> connect 'jdbc:derby:db;create=true';  
> ij> create table s1.t1(x int);
> 0 rows inserted/updated/deleted
> ij> create table s2.t2(x int);
> 0 rows inserted/updated/deleted
> ij> set schema s1;
> 0 rows inserted/updated/deleted
> ij> create trigger tr1 after insert on t1 insert into s2.t2 select * from t1;
> 0 rows inserted/updated/deleted
> ij> set schema s2;
> 0 rows inserted/updated/deleted
> ij> create trigger tr2 after insert on s1.t1 insert into t2 select * from s1.t1;
> 0 rows inserted/updated/deleted
> ij> exit;
> Then run dblook on the created database:
> -- Timestamp: 2013-10-04 12:46:14.974
> -- Source database is: db
> -- Connection URL is: jdbc:derby:db
> -- appendLogs: false
> -- ----------------------------------------------
> -- DDL Statements for schemas
> -- ----------------------------------------------
> CREATE SCHEMA "S1";
> CREATE SCHEMA "S2";
> -- ----------------------------------------------
> -- DDL Statements for tables
> -- ----------------------------------------------
> CREATE TABLE "S1"."T1" ("X" INTEGER);
> CREATE TABLE "S2"."T2" ("X" INTEGER);
> -- ----------------------------------------------
> -- DDL Statements for triggers
> -- ----------------------------------------------
> CREATE TRIGGER "S1"."TR1" AFTER INSERT ON "S1"."T1" FOR EACH STATEMENT insert into s2.t2
select * from t1;
> CREATE TRIGGER "S2"."TR2" AFTER INSERT ON "S1"."T1" FOR EACH STATEMENT insert into t2
select * from s1.t1;
> dblook should either qualify all identifiers in the trigger actions, or contain SET SCHEMA
statements before each of the CREATE TRIGGER statements to ensure the correct implicit schema
is chosen.
