Php sqlplus中的嵌套查询

我需要创建一个名为salary的新表，它包含两列：第一列是e_id，第二列是salary

但首先我需要根据这个等式计算每个员工的工资

---

Sal=e_bsal+suma_val–sumd_val

您的问题标题是SQL plus；意思是甲骨文。您正在为mysql和MSSQL添加标记。选择employee.e_id，employee.e_bsal+子问题1.total_allow-subqueary2.total_从employee中扣除，选择e_id，suma_val作为总允许从津贴中扣除，津贴交易，其中津贴.a_id=津贴，按e_id子项1交易，a_id分组，其中子项1.e_id=员工.e_id，并选择e_id，sumd_val作为从扣除中扣除的总额，扣除交易，其中扣除.d_id=按e_id子项2扣除，其中子项2.e_id=员工.e_id；按e_id分组第12行的子问题2错误：ORA-00936:缺少表达式您可以对表格和数据进行修改吗
