simplyi Posted January 15, 2010 Share Posted January 15, 2010 Please advise me a sample query or good tutoral to read about selecting distinct values from multimple tables. I have tree tables A,B,C all linked by id. table B has id of A table C has id of B If I run a query select a.name, b.address, c. phone then from a,b,c order by a.id then I get a selection form all three tables but I NEED a.NAME to be distinct. Please advise..... Thank you Link to comment https://forums.phpfreaks.com/topic/188591-select-distinct-values-from-multiple-tables/ Share on other sites More sharing options...
dreamwest Posted January 16, 2010 Share Posted January 16, 2010 Grouping is important when select * distinct $res = mysql_query( "SELECT distinct * FROM table_a as a, table_b as b, table_c as group by a.name ORDER BY a.id ASC"); Otherwise try this assumed method: $res = mysql_query( "SELECT distinct name FROM table_a as a, table_b as b, table_c as group by a.name ORDER BY a.id ASC"); Link to comment https://forums.phpfreaks.com/topic/188591-select-distinct-values-from-multiple-tables/#findComment-995926 Share on other sites More sharing options...
