Review comment:
This doesn't appear to be the case. For example if the query is:
`SELECT count(*) from mytable WHERE intColumn < 3000000000.453`
then `stringValue` gets set to 3000000000.453 and the current code would
throw exception because 3000000000.453 is not a valid integer.
After the change, the above query will evaluate successfully (which is
expected SQL behavior). Same with other queries such as:
`SELECT count(*) from mytable WHERE intColumn = 5.0`
