报错信息

用户USER2对表USER1.T1本身有DML权限。

用户USER2往USER1的表T1插入数据报错 ORA-01950：

 Error : 1950, Position : 20, SQL = INSERT INTO USER1.T1 (L_DATE)VALUES (:1 ) RETURNING ROWID INTO :2  [SQL INCLUDES EXPRESSIONS ADDED BY THE ORACLE JDBC DRIVER], Original SQL = INSERT INTO USER1.T1 (L_DATE)VALUES (?) RETURNING ROWID INTO ?, Error Message = ORA-01950: 对表空间 'TBS1' 无权限

授权但是没用？

对用户USER2授予表空间TBS1的使用权限：

-- 三种授权方式任意一种都可
alter user USER2 quota unlimited on TBS1;	
grant unlimited tablespace to USER2;<
