sql查询报错：[Err] ORA-00913: too many values

 查询sql：

SELECT * from T_QL_CASE q 
where q.CASE_OID IN(
select f.CASE_OID,f.FINAL_STATUS 
from T_QL_CASE_APPROVAL_FINAL f 
where FINAL_STATUS='2' 
OR  FINAL_STATUS='33' 
OR  FINAL_STATUS='43' 
OR  FINAL_STATUS='34' 
OR  FINAL_STATUS='5');

问题缘由：

SELECT * from T_QL_CASE q 
where q.CASE_OID IN(
select f.CASE_OID,f.FINAL_STATUS 
from T_QL_CASE_APPROVAL_FINAL f 
where FINAL_STATUS='2' 
OR  FINAL_STATUS='33' 
OR  FINAL_STATUS='43' 
OR  FINAL_STATUS='34' 
OR  FINAL_STATUS='5');

两个红色的地方，where后面的列数应该和 in(select cloum1,clounm2)中select的列数相同。

 

当INSERT报这个错误时，通常是插入数据的列数不一致。

 

原sql：
insert into abc.employees select * from employees where employee_id=100; 
报错：
Error starting at line 1 in command:
insert into abc.employees select * from employees where employee_id=100; 

Error at Command Line:1 Column:25
Error report:
SQL Error: ORA-00913: too many values
00913. 00000 -  "too many values"
*Cause:    
*Action:



解决办法：：：

应按以下所示指定列名称
insert into abc.employees (col1,col2) 
select col1,col2 from employees where employee_id=100; 



若是employees有112列（原文如此！）尝试在下面运行以选择比较两个表的列
select * 
from ALL_TAB_COLUMNS ATC1
left join ALL_TAB_COLUMNS ATC2 on ATC1.COLUMN_NAME = ATC1.COLUMN_NAME 
                               and  ATC1.owner = UPPER('2nd owner')
where ATC1.owner = UPPER('abc')
and ATC2.COLUMN_NAME is null
AND ATC1.TABLE_NAME = 'employees'
而后您应该将表升级为具备相同的结构
