我正在尝试在表格列上应用 sum 函数，但我收到错误消息

ORA-00934: group function is not allowed here
00934. 00000 -  "group function is not allowed here"
*Cause:    
*Action:
Error at Line: 46 Column: 5

这是查询

select LOSA_APP.app_ref_no AS "App.Ref.No.",  
   CODE_BRANCH.branch_name AS "BRANCH",
   CODE_STAFF.staff_name AS "Officer Name",
   LOSA_CUST.full_name AS "Borrower",
   LOSA_FACILITIES.fac_type AS "Facility Type",
   losa_facilities.amt_appr AS "Limit"
from losa_app LOSA_APP
...
INNER JOIN
    losa_facilities LOSA_FACILITIES
ON
    LOSA_APP.app_ref_no = LOSA_FACILITIES.app_ref_no
where 
    LOSA_APP.app_status='A' 
and 
    .....
and 
    sum(losa_facilities.amt_appr)

第 46 行sum(losa_facilities.amt_appr)我也试过sum(losa_facilities.amt_appr) group by losa_facilities.amt_appr，但没有用。

为什么这么说group function is not allowed here ?。我做错了什么？

谢谢

错误

ORA-00936: missing expression
00936. 00000 -  "missing expression"
*Cause:    
*Action:
Error at Line: 46 Column: 5

第 46 行是GROUP BY (LOSA_APP.app_ref_no, CODE_BRANCH.branch_name,...

我也试过这个

select LOSA_APP.app_ref_no AS "App.Ref.No.",  
   CODE_BRANCH.branch_name AS "BRANCH",
   CODE_STAFF.staff_name AS "Officer Name",
   LOSA_CUST.full_name AS "Borrower",
   LOSA_FACILITIES.fac_type AS "Facility Type",
   sum(LOSA_FACILITIES.amt_appr) AS "Limit"
from losa_app LOSA_APP
INNER JOIN
....

只需在 select 子句中使用 sum，但在这种情况下，我会收到错误消息

ORA-00937: not a single-group group function
00937. 00000 -  "not a single-group group function"
*Cause:

要使用聚合函数（如 SUM/AVERAGE 等），您需要使用GROUP BY子句对结果进行分组。要基于列的聚合过滤结果，您应该GROUP BY对选定的列执行 a，然后使用HAVING子句指定过滤器

select LOSA_APP.app_ref_no AS "App.Ref.No.",  
   CODE_BRANCH.branch_name AS "BRANCH",
   CODE_STAFF.staff_name AS "Officer Name",
   LOSA_CUST.full_name AS "Borrower",
   LOSA_FACILITIES.fac_type AS "Facility Type",
   losa_facilities.amt_appr AS "Limit"
from losa_app LOSA_APP
...
INNER JOIN
    losa_facilities LOSA_FACILITIES
ON
    LOSA_APP.app_ref_no = LOSA_FACILITIES.app_ref_no
where 
    LOSA_APP.app_status='A' 
and 
    .....
GROUP BY <all the columns in the  SELECT clause above, except those on which aggregate functions are applied>
HAVING sum(losa_facilities.amt_appr) <relational operator and value>

SUM() 和其他分组依据函数必须出现在 HAVING 子句中，而不是 WHERE 子句中。
