you need a sql book: you sumarized your question so well, you can find the answer in any sql book in a minute, literally: select a.some, a.someelse, a.reference, b.referee, b.somesome, b.somesomeelse from tableA a, tableB b where b.referee = a.refference hope helps.

Not every row in the first tablehas a reference to the second table. I now want to make a query to get all information of the first table and, if thereis a reference, the corresponding information of the second table in that row. In another programming language I wouldjust make an if-clause but how can I do this in SQL? > > Thanks for your help > > Michael >
