Hi there, I am using H2 in my project (dhis2.org) and its serving our needs very well.
However from version 1.2.130 there is a change in behavior for select queries with IN-conditions with indexes. The following query used to return 4 distinct rows but is now returning 8 rows, where each row is duplicated. The same query is returning 4 rows in PostgreSQL and is breaking our cross-database tests. I have created a test case: --------------------------------------------------------------------------------------------------- create table test ( a integer not null, b integer not null, c varchar(30) ); create index index_test on test (a,b); insert into test values (1,1,'a'); insert into test values (1,2,'b'); insert into test values (2,1,'c'); insert into test values (2,2,'d'); select * from test where a in (1,2) and b in (1,2); --------------------------------------------------------------------------------------------------- I am interested to hear whether this is a bug or expected behavior. Thanks a lot for your help. -- You received this message because you are subscribed to the Google Groups "H2 Database" group. To post to this group, send email to [email protected].
