sql查詢報錯：[Err] ORA-00913: too many values

 查詢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');

問題緣由：

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');

兩個紅色的地方，where後面的列數應該和 in(select cloum1,clounm2)中select的列數相同。

 

當INSERT報這個錯誤時，通常是插入數據的列數不一致。

 

原sql：
insert into abc.employees select * from employees where employee_id=100; 
報錯：
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:



解決辦法：：：

應按以下所示指定列名稱
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！）嘗試在下面運行以選擇比較兩個表的列
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'
而後您應該將表升級爲具備相同的結構
