CAST to DECIMAL in MySQL

Question

I am trying to cast to Decimal in MySQL like this:

CAST((COUNT(*) * 1.5) AS DECIMAL(2))

I\'m trying to convert the number of rows in a tabl

Answer 1

From MySQL docs: Fixed-Point Types (Exact Value) - DECIMAL, NUMERIC:

In standard SQL, the syntax DECIMAL(M) is equivalent to DECIMAL(M,0)

So, you are converting to a number with 2 integer digits and 0 decimal digits. Try this instead:

CAST((COUNT(*) * 1.5) AS DECIMAL(12,2))
