not sure if such question are on-topic here. (where would this
question be on-topic ?)
I need to join two tables with a logical "if-statement". If for a
certain row in table1 there is a related row in table2, then take the
row from table2 else take it from table1. The relation is a simple
equal on one column.
example:
table1:
uid | name
----+-----
1 | bob
2 | jim
3 | tom
table2:
uid | name
----+-----
2 | frank
the final join should return:
uid | name
----+-----
1 | bob
2 | frank
3 | tom
I played around with joins and intersects and distincts but only ended
up in complex unperformant queries that didnt do what I intended. I
miss the basic idea how to solve this.
thnx,
peter
