Question

Когда я выполняю запрос

SELECT Settlement_Fees.Participant_Name, Settlement_Fees.Account, Settlement_Fees.Billing_Account, Settlement_Fees.Descr1, Settlement_Fees.Market, Settlement_Fees.Instrum
--, IIf(Settlement_Fees.Instr_Type='Internal','bsinternal',Settlement_Fees.Instr_Type) AS Expr1
,(case when Settlement_Fees.Instr_Type='Internal' then 'bsinternal'
  else Settlement_Fees.Instr_Type
 end )
, Settlement_Fees.Country, Settlement_Fees.Nr_Instr_Business_Unit, Settlement_Fees.Nr_Instr_Account, Settlement_Fees.Avg_EUR_Rate, Settlement_Fees.Fee_Amount_EUR, Settlement_Fees.Value_Date_Adj
FROM Settlement_Fees)
union all
 (select '','',Billing_Account,'','','',
( case when Instr_Type like '%Bridge%' or Instr_Type = '%Internal%' then 'Bszridge/Internal'
else  Instr_Type
end )
 ,'','',Nr_Instr_Account  ,'',Fee_Amount_EUR ,'' 
from Settlement_Fees group by Settlement_Fees.Billing_Account,Settlement_Fees.Instr_Type
,Settlement_Fees.Nr_Instr_Account,Fee_Amount_EUR)
union all 
(select '','',Billing_Account,'','','','Total','','',sum(Nr_Instr_Account),'',sum(Fee_Amount_EUR) ,''
from Settlement_Fees group by Billing_Account

Работает нормально

но когда я выполняю команду select * from (), это дает мне ошибку "Msg 102, Level 15, State 1, Line 33 Неверный синтаксис рядом с ')'. "Для следующего запроса

SELECT *

Answer 1

Вы должны назвать свой подзапрос:

Выберите * из () имя подзапроса

 select * from(
(SELECT Settlement_Fees.Participant_Name, Settlement_Fees.Account, Settlement_Fees.Billing_Account, Settlement_Fees.Descr1, Settlement_Fees.Market, Settlement_Fees.Instrum
--, IIf(Settlement_Fees.Instr_Type='Internal','bsinternal',Settlement_Fees.Instr_Type) AS Expr1
,(case when Settlement_Fees.Instr_Type='Internal' then 'bsinternal'
  else Settlement_Fees.Instr_Type
 end )
, Settlement_Fees.Country, Settlement_Fees.Nr_Instr_Business_Unit, Settlement_Fees.Nr_Instr_Account, Settlement_Fees.Avg_EUR_Rate, Settlement_Fees.Fee_Amount_EUR, Settlement_Fees.Value_Date_Adj
FROM Settlement_Fees)
union all
 (select '','',Billing_Account,'','','',
( case when Instr_Type like '%Bridge%' or Instr_Type = '%Internal%' then 'Bszridge/Internal'
else  Instr_Type
end )
 ,'','',Nr_Instr_Account  ,'',Fee_Amount_EUR ,'' 
from Settlement_Fees group by Settlement_Fees.Billing_Account,Settlement_Fees.Instr_Type
,Settlement_Fees.Nr_Instr_Account,Fee_Amount_EUR)
union all 
(select '','',Billing_Account,'','','','Total','','',sum(Nr_Instr_Account),'',sum(Fee_Amount_EUR) ,''
from Settlement_Fees group by Billing_Account
)) subqueryName

Answer 2

Вам необходимо указать псевдоним таблицы для производной таблицы. например добавьте as t в самый конец запроса.

Дополнительно, чтобы исправить проблему, поднятую в комментарии, измените

( CASE
                   WHEN settlement_fees.instr_type = 'Internal' THEN
                   'bsinternal'
                   ELSE settlement_fees.instr_type
                 END )

до

   CASE
       WHEN settlement_fees.instr_type = 'Internal' THEN
       'bsinternal'
       ELSE settlement_fees.instr_type
     END AS Foo

Answer 3

Вам необходимо дать имя производной таблице. Неважно, что. Например:

SELECT
   ...
FROM
   (...derived table) myDerivedTableName

Answer 4

У вас есть дополнительный набор (), и псевдоним для встроенного представления / производной таблицы также помогает, например,

select * from(
    SELECT 
        Settlement_Fees.Participant_Name, 
        Settlement_Fees.Account, 
        Settlement_Fees.Billing_Account, 
        Settlement_Fees.Descr1, 
        Settlement_Fees.Market, 
        Settlement_Fees.Instrum,
        (case when Settlement_Fees.Instr_Type='Internal' then 'bsinternal'
            else Settlement_Fees.Instr_Type
        end ) as SomthingHere, 
        Settlement_Fees.Country, 
        Settlement_Fees.Nr_Instr_Business_Unit, 
        Settlement_Fees.Nr_Instr_Account, 
        Settlement_Fees.Avg_EUR_Rate, 
        Settlement_Fees.Fee_Amount_EUR, 
        Settlement_Fees.Value_Date_Adj
    FROM Settlement_Fees
    UNION ALL select 
        '',
        '',
        Billing_Account,
        '',
        '',
        '',
        ( case when Instr_Type like '%Bridge%' or Instr_Type = '%Internal%' then 'Bszridge/Internal'
        else  Instr_Type
        end ),
        '',
        '',
        Nr_Instr_Account  ,
        '',
        Fee_Amount_EUR ,
        '' 
    from 
        Settlement_Fees 
    group by 
        Settlement_Fees.Billing_Account,
        Settlement_Fees.Instr_Type,
        Settlement_Fees.Nr_Instr_Account,
        Fee_Amount_EUR
    union all select 
        '',
        '',
        Billing_Account,
        '',
        '',
        '',
        'Total',
        '',
        '',
        sum(Nr_Instr_Account),

        Settlement_Fees
