Question

I have a table MYTABLE.
This contains customers and locations.

What Sql statement can I use to find out what customers have more than 1 location
and only display on those with more than 1 location? A location can be used for several different customers.

This did not work: this only showed the number of Occurances

SELECT CU _NO, LOC_NO, COUNT(LOC_NO) AS NUMBEROCC
FROM MYTABLE
GROUP BY LOC_NO
HAVING (COUNT(LOC_NO)>1)

The table has more than one row of of the same customer(sorry this was important)

Answer 1

SELECT m.CU_NO
     , m.LOC_NO
     , grp.NUMBEROCC
FROM MYTABLE AS m
  JOIN
    ( SELECT CU_NO
           , COUNT(DISTINCT LOC_NO) AS NUMBEROCC
      FROM MYTABLE
      GROUP BY CU_NO
      HAVING COUNT(DISTINCT LOC_NO) > 1
    ) AS grp
    ON grp.CU_NO = m.CU_NO
ORDER BY m.CU_NO
