Question

I need to create a query that will sum the number of True(1) and False(0) into two separate columns from one bit field.

I’m joining 3 tables and need it to be something like:

Attribute | Class | Pass | Fail

I will be grouping on Attribute and Class.

Answer 1

Something like this:

SUM(CASE WHEN ColumnName = 1 THEN 1 ELSE 0 END) AS Pass, 
SUM(CASE WHEN ColumnName = 0 THEN 1 ELSE 0 END) AS Fail
