9.3.7 INTEGER

The JDBC type INTEGER represents a 32-bit signed integer value ranging between -2147483648 and 2147483647.
The corresponding SQL type, INTEGER, is defined in SQL-92 and is widely supported by all the major databases. The SQL-92 standard leaves the precision of INTEGER up to the implementation, but in practice all the major databases support at least 32 bits.
The recommended Java mapping for the INTEGER type is as a Java int.
