Question

I am fairly new to SQL joins, but I have a tricky issue here. I have tried to resolve this on my own, and searched as well, but unsuccessful.

I have two primary SQL tables

CustProfile

ClientID || ClientName 

CustTransaction

CorpID || DivID || DeptID 

I need to display my output as follows:

`CorpID` `CorpIDClientName` `DivID` `DivIDName` `DeptID` `DeptIDName`  

CustTransaction.CorpID join on CustProfile.ClientID to get `CorpIDClientName`  
CustTransaction.DivID join on CustProfile.ClientID to get `DivIDName`  
CustTransaction.DeptID join on CustProfile.ClientID to get `DeptIDName`  

I hope someone can provide the join query. Thanks in advance

try this one:

SELECT  a.CorpID,
        b.ClientName AS CorpIDClientName,
        a.DivID,
        c.ClientName AS DivIDName,
        a.DeptID,
        d.ClientName AS DeptIDName
FROM    CustTransaction a
            INNER JOIN CustProfile b
                on a.CorpID = b.ClientID
            INNER JOIN CustProfile c
                on a.DivID = c.ClientID
            INNER JOIN CustProfile d
                on a.DeptID = d.ClientID
