Ops,

This is mistake in docs.
In the C SDK there is no need delete returned strings,
But you must copy them into own buffer immediately.

Yes, but note.

You should escape ONLY string constants.

        WHERE fld = 'string to be escaped'
        
There is no need escape the whole sql query string
