Hello All! I used MySQL for a long time. There is SET() conception. I can define SET('one','two','three') and use that type: CREATE TABLE "test" ( "a" SET('one','two','three') }; And then: SELECT * FROM test WHERE a = 'one'; or SELECT * FROM test WHERE a like 'one,three'; How can I do it in PgSQL? I need it so much! -- with respection Andrey Feofilactovich. e-mail: [EMAIL PROTECTED], [EMAIL PROTECTED] ICQ: 28073807
