Hi all,

I have this tricky (for me) table join to make. I need to get the info field out of tables Type1Clients and Type2Clients so I have the resultTable shown at the bottom.

I could join AllClients to Type1Clients then union this with AllClients joined to Type2Clients but that won't give me all the information in one row. How can I do this?
Thanks.


AllClients
idType1 idType2
1_0001  2_0001
1_0002  2_0002


Type1Clients
id              info
1_0001  i101
1_0002  i102

Type2Clients
id              info
2_0001  i201
2_0002  i202

resultTable
idType1 idType2 infoTyp1        infoTyp2
1_0001  2_0001  i101            i201
1_0002  2_0002  i201            i201
