insert into test select x, '' from system_range(1, 10000);
-- fast
update test set name = 'y' where cast(id as varchar) like '1%';
-- slow
update test set name = 'x' where id in (select x from system_range(1, 10000) where cast(x as varchar) like '1%');
drop table test;
Optimize IN(...), IN(select), ID=? OR ID=?: create temp table and use join
Bug:
H2 1.0.62 (2007-11-25) has regressed on this query. Parser syntax error is returned (query is OK for derby, oracle, and earlier H2 versions).
SELECT COUNT(*) FROM (
SELECT TT.id,TT.table_name FROM (
SELECT DISTINCT id, table_name FROM information_schema.tables WHERE id=-8 UNION SELECT DISTINCT id, table_name FROM information_schema.tables WHERE id=-8) AS TT
) AS AWR WHERE AWR.id=-8
Remove the final predicate and the query parses & runs fine:
SELECT COUNT(*) FROM (
SELECT TT.id,TT.table_name FROM (
SELECT DISTINCT id, table_name FROM information_schema.tables WHERE id=-8 UNION SELECT DISTINCT id, table_name FROM information_schema.tables WHERE id=-8) AS TT
) AS AWR
write more tests for the command line tools
Changelog:
Certain setting in the Server didn't work (see bug...)
