四、oracle表结构移植到mysql中需要的类型转换
MYSQL ORACLE
BLOB(220) RAW(220)BLOB (20) RAW(20)BLOG(1024) RAW(1024) VARCHAR(n) VARCHAR2(n)CHAR CHARFLOAT(22,6) NUMBER(22,6)DOUBLE(44,12) NUMBER(44,12)TINYINT (3) NUMBER(3)SMALLINT(5) NUMBER(5)MEDIUMINT(8) NUMBER(8)INT(10) NUMBER(10)BIGINT(20) NUMBER(20)DATATIME DATA五、mysql和oracle数据类型对应关系参照表
