oracle INTEGER, INT is converted to mysql as INT(11), but Oracle's extreme data cannot be accepted

[asiroliu]

Steps to reproduce the issue

1. oracle sql

CREATE TABLE TEST.INTEGER_COLUMNS(col1 INT, col2 INTEGER);
INSERT INTO TEST.INTEGER_COLUMNS VALUES (1, -9999999999999999999999999999999999999999);
INSERT INTO TEST.INTEGER_COLUMNS VALUES (2, 9999999999999999999999999999999999999999);

2. dest dtle log

Oracle INT/INTEGER类型最大数值存储可到127位数（十进制），MySQL 没有数值类型可以存储最大值。 目前使用统一INT来做类型映射。极值问题不处理
