Construct SQL SELECT Query inside SQLStatementUpdateCheck

Instead of running complex SQL Select query that is being passed from SQLEngine to SQLStatementUpdate and then to SQLStatementUpdateCheck. That sql SELECT query involves the joins which is useless because we only need to run the update failure check on the table on which we are running update query in SQLStatementUpdate.

So now there is no need to pass sql from SQLEngine to SQLStatementUpdate and then to SQLStatementUpdateCheck. Now we are building the SELECT sql query inside SQLStatementUpdateCheck.

Will add patch after adding few comments.
