hello all! <br><br>i don't know how to get this update statement in sqlserver7<br>running. i guess it's a syntax problem... <br><br>table A (field1 Id, field2 Data,...)<br>table B (field1 Id, field2 Data)<br><br>B is a "temporary" table that has a corresponding "Data"<br>for each Id. in table A this field is empty:<br><br>A.Id ¦ A.Data B.Id ¦ B.Data<br>------------- ----------------<br>1 ¦ NULL 1 ¦ Value1<br>2 ¦ NULL 2 ¦ Value2<br>3 ¦ NULL 3 ¦ Value3<br><br>now i want to copy B.Data to A.Data which looks very simple<br>but... i could not find the correct update-syntax. how do i<br>"join" an update and a join?<br><br>any help would be greatly appreciated! TIA<br><br>--ralf<br>
