Question

I want a query to select more than 4 AccountId repetitions from table2 having distinct name in table1

Here are the table structures:

table1                             |       Table2
ID   AccountNumber  Name           |       ID       AccountNumber AccountID
1     12345         John Jeff      |        1          12345        A467T
1     12345         Patrick Jones  |        1          12345        A467T

ID and AccountNumber are the same on both tables

• Table1 has Name
• Table2 has AccountID

Answer 1

Here’s a query to find AccountID’s with more than 4 different names:

select  t2.AccountID
from    Table1 as t1
join    Table2 as t2
on      t1.AccountNumber = t2.AccountNumber
        and t1.ID = t2.ID
group by
        t2.AccountID
having  count(distinct t1.Name) > 4

If that’s not what you were looking for, please clarify the question! For examole, you could add desired output.

EDIT: In reply to your comment, you could query the ID and Numbers with a subquery:

select  distinct 
        ID
,       AccountNumber
,       AccoutnID
from    Table2
where   AccountNumber in 
        (
