Do yourself a big favor: don't convert, avoid using string types where you should use numeric types.

Solution 2

Try this:

SQL

CONVERT(NUMERIC(18, 2), YourData)

Or

SQL

CASTE(YourData as NUMERIC(18, 2))

I would suggest you to read Data Type Conversion (Database Engine)[^] and CAST and CONVERT (Transact-SQL)[^] functions.

Hope it helps!
