Question

I have a DB of raw data that has everything as varchar, one of the columns contains a price, which for the most part would convert into FLOAT easily. However, there are a few rows that have trash in that column with a bunch of characters and would not convert to float.

Is there a way to select only that rows that would convert to float (i.e. only the ones taht actually have a number)?

Thanks

Note: It is important to include the + 'e0' in the numeric test, as things like '+', '$', '.' and '3e8' would otherwise all return 1.

SELECT *
    FROM YourTable
    WHERE ISNUMERIC(YourColumn + 'e0') = 1
