oracle怎么批量授权用户表

要批量授权用户表，您可以使用Oracle的GRANT语句来实现。以下是一个示例：
```sql
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table_name TO user_name;
```
其中，`schema_name`是用户表所在的模式名称，`table_name`是要授权的表名称，`user_name`是要授权的用户名。
如果要为多个用户表进行批量授权，可以使用循环或者用逗号分隔的方式来授权多个表，例如：
```sql
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table1 TO user_name1;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table2 TO user_name1;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table3 TO user_name1;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table1 TO user_name2;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table2 TO user_name2;
GRANT SELECT, INSERT, UPDATE, DELETE ON schema_name.table3 TO user_name2;
```
您可以根据实际情况修改上述语句来适应您的需求。
