How do I remove “duplicate” rows from a view?

Question

I have a view which was working fine when I was joining my main table:

LEFT OUTER JOIN OFFICE ON CLIENT.CASE_OFFICE = OFFICE.TABLE_CODE.

Instead of using DISTINCT, you could use a GROUP BY.

• Group by all the fields that you want to be returned as unique values.
• Use MIN/MAX/AVG or any other function to give you one result for fields that could return multiple values.

Example:

SELECT Office.Field1, Client.Field1, MIN(Office.Field1), MIN(Client.Field2)  
FROM YourQuery  
GROUP BY Office.Field1, Client.Field1
