You're welcome. I had the exact same reaction when I learned the name. :)

>Thank you, Hank. Now that I know the name, it is easier to Google and find all kinds of postings.

>>>Hi,

>>>How I would create a SQL Select for the following case:
>>>Table 1
>>>

>>>PART_NO   PART_PK    PART_QTY
>>>"123"          1                 34
>>>"ABC"         2                 0
>>>"NBZ"         3                 12
>>>

>>>
>>>Table 2
>>>

>>>PART_PK       QTY
>>>1                    3
>>>1                    4
>>>1                    10
>>>3                     1
>>>2                     6
>>>3                     2
>>>2                     35
>>>

>>>
>>>Resulting query should be
>>>

>>>PART_NO         PART_QTY      ACT_QTY   (Act Qty is SUM of QTY in Table 2 field QTY)
>>>"123"                34                   17
>>>"ABC"               0                      41
>>>"NBZ"              12                     3
>>>

>>>
>>>TIA
>>>
>>>UPDATE: I know that the SQL Select should consist of two SQL Select:
>>>

>>>select PART_NO, PART_QTY ..... (SELECT SUM(QTY) AS ACT_QTY from Table2 GROUP BY PART_PK) AS ACT_QTY FROM Table1
>>>

>>>
>>>But I don't know how to "connect" the main SQL Select with the SUB-SQL Select
