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

DECIMAL has two parts: Precision and Scale. So part of your query will look like this:

CAST((COUNT(*) * 1.5) AS DECIMAL(8,2))

Precision represents the number of significant digits that are stored for values.
Scale represents the number of digits that can be stored following the decimal point.
