Hi List; I've found that if I run this select (below) I get a table returned named 'dma' een though I specified like 'dm_%' : select tablename from pg_tables where tablename like 'dm_%'; tablename ------------------------------ dm_service_provider_dim dma Am I missing something or is this a bug ? Thanks in advance.. /Kevin >> the '_' character is a especial character like the '%'.... Try use this >>select * from table where name ilike('dm\\_%')
