As a total beginner who has for decades used an application that would allow type mismatches like boolean*numeric I
triedthe following select:
SELECT sum(cost*quantity)*(sales_type=1) AS sales_type1, sum(cost*quantity)*(sales_type=2) AS sales_type2 FROM etc etc
In the above, cost and quantity are TYPE numeric(9,2), sales_type is smallint.
PostgreSQL does not allow numeric*boolean. The error message ends with "You might need t" which kinda leaves me
hanging.
Any clues would be most welcome.
