Java 1.7 CachedRowSet.populate() turns MySQL TINYINT(1) into Boolean. Can this be disabled?

Question

As the title states, feeding a ResultSet that contains a TINYINT(1) column to a CachedRowSet throught its populate() method will convert the values in that column to booleans with values false for 0 and true for anything above. This loses the original value and makes a getInt() call for that column throw an exception.

Can this behaviour be disabled? TINYINT(1) is also very useful for hardcoded types and statuses. It's a number with 1 digit, not a number where 1 is max value. No reason to treat it as boolean, really.

Anything I can do to disable this when instantiating CachedRowSetImpl?

在SQL中使用强制转换 ，这样您就可以返回普通的int了：

select cast(tinyIntColumn as int) from someTable
