Hi,

I am running a SQL query in Excel with an external parameter PARAM from a cell with values 'Yes' or 'No':


SELECT A,B,C
FROM Table

The C column either contains NULL or 1

How do I filter in the WHERE clause so that I get:
ALL results if PARAM is 'No'
C= 1 if the PARAM is 'Yes'

I tried several things with SELECT CASE, but up until now without any results.
Can anyone help me out here ?

Thx,
Arnold

Try this

SELECT A,B,C
FROM Table
WHERE (PARAM ='No') or
(C= 1 AND PARAM ='Yes')

simply this would do it right


SELECT A,B,C
FROM Table
WHERE (@PARAM = 'No'
OR C = 1)

Assuming PARAM allows only values as Yes and No
