数据库操作类型权限(DataBaseOperations License)可以分为以下几种:

1. SELECT:指示在当前应用程序中查询具有指定列(包括其子列或列中的所有行)的SELECT操作: SELECT * FROM table1 SELECT * FROM table2 SELECT * FROM table3 SELECT * FROM table4 SELECT * FROM table5 SELECT * FROM table6 SELECT * FROM table7 SELECT * FROM table8 SELECT * FROM table9 SELECT * FROM table10

2. WHERE:指示在当前应用程序中查询所有行的WHERE操作: WHERE a column IN (SELECT * FROM a) AND a column WHERE a column IN (SELECT * FROM a + 1, 2, 3, 4, 5, 6, 7); 或者WHERE a column IN (SELECT * FROM a, WHERE a + 1, 2, 3, 4, 5, 6, 7);

3. ORDER BY:指示在当前应用程序中查询所有行的ORDER BY操作: ORDER BY a column IN (SELECT * FROM a) AND a column ORDER BY a column = FROM a + 1; ORDER BY a column IN (SELECT * FROM a, SELECT * WHERE a, a); ORDER BY a column IN (SELECT * FROM a + 1, 2, 3, 4, 5, 6, 7, 8); ORDER BY a column IN (SELECT * FROM a + 1, WHERE a, a); 或者ORDER BY a column IN (SELECT * FROM a, SELECT * WHERE a, a);

4. HAVING:指示在当前应用程序中只查询需要查询操作的SELECT操作。

这些权限可以根据具体情况不同而进行调整。
