your where condition looks flawed:
select count (*) as NEWCOL
from table1
where COL1 = 'val1'
and COL2 = 'val1'
and (COL3 = 'val1' or COL3 = 'val2')
;
Question
New to SQL and I am struggling with a query to have multiple values from a column counted and added together. Here is the query
select count (*) as NEWCOL
from table1
where COL1 = 'val1' and COL2 = 'val1' and COL3='val1' or 'val2'
La solution

Autres conseils
Try this:
SELECT
COUNT(y.*) as NewCol
,x.[allfields] as WhatyouWantitToBe
FROM
table1 y
OUTER APPLY
(SELECT
x.col1 + ' ' + x.col2 + ' ' + x.col3 AS [allFields]
FROM
table1 x
WHERE
x.col1 = y.col1
AND
x.col2 = y.col2
AND
x.col3 = y.col3) AS x
WHERE
y.COL1 = 'val1'
AND y.COL2 = 'val1'
AND (y.COL3 = 'val1'
OR
y.COL3 = 'val2')
And then again, that's what can be done with what you mentioned. A concatenation of varchar field as well as a count.
