CTE 错误：逗号附近的语法不正确

Question

谁能给点灯：

逗号附近出现错误：

  ;with cteClaims as (
    select a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
      FROM [spd].[claims].[Population] a                    
      group by a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
      having a.ClaimStatus not in ('Closed', 'Denied', 'Paid')                  
      ), ctePopulation as (  
      select a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                 
      FROM [spd].[claims].[Population] a                    
      join cteClaims b on a.LoanId = b.LoanId                   
      group by a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription)  
       select loanid as cteLoanId 
        from [spd].[claims].[Population] where id in (select id from ctePopulation)
   /// Error is here near this comma  below 
     , cteLoanBase as (
        select 
               a.LoanId as [Loan#]
             , a.AcquisitionDt as [AcquisitionDt]
             , a.CorpRecoverableBalanceAmt as [CorpRecoverableBalanceAmt]
             , a.EscrowBalance as [EscrowBalance]
             , a.FirstPaymentDueDt as [FirstPaymentDueDt]
             , a.InvestorLoanId as [InvestorLoanId]
             , a.InvestorPoolId as [InvestorPoolId]
             , a.LoanStatusId as [LoanStatusId]

Answer 1

如果你更好地缩进你的代码也许会有所帮助......

您的代码：

 ;with 
    cteClaims as (
        SELECT a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
        FROM [spd].[claims].[Population] a                    
            GROUP BY a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
              HAVING a.ClaimStatus not in ('Closed', 'Denied', 'Paid')),
    ctePopulation as (  
        SELECT a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                 
        FROM [spd].[claims].[Population] a                    
        JOIN cteClaims b on a.LoanId = b.LoanId                   
        GROUP BY a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription)  

    SELECT loanid as cteLoanId 
        FROM [spd].[claims].[Population] 
    WHERE id in (select id from ctePopulation)

   /// Error is here near this comma  below 


     , cteLoanBase as (
        select 
               a.LoanId as [Loan#]
             , a.AcquisitionDt as [AcquisitionDt]
             , a.CorpRecoverableBalanceAmt as [CorpRecoverableBalanceAmt]
             , a.EscrowBalance as [EscrowBalance]
             , a.FirstPaymentDueDt as [FirstPaymentDueDt]
             , a.InvestorLoanId as [InvestorLoanId]
             , a.InvestorPoolId as [InvestorPoolId]
             , a.LoanStatusId as [LoanStatusId]

我的猜测：

 ;with 
    cteClaims as (
        SELECT a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
        FROM [spd].[claims].[Population] a                    
            GROUP BY a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
              HAVING a.ClaimStatus not in ('Closed', 'Denied', 'Paid')),
    ctePopulation as (  
        SELECT a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                 
        FROM [spd].[claims].[Population] a                    
        JOIN cteClaims b on a.LoanId = b.LoanId                   
        GROUP BY a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription),
    cteLoanBase as (
        SELECT 
                   a.LoanId as [Loan#]
                 , a.AcquisitionDt as [AcquisitionDt]
                 , a.CorpRecoverableBalanceAmt as [CorpRecoverableBalanceAmt]
                 , a.EscrowBalance as [EscrowBalance]
                 , a.FirstPaymentDueDt as [FirstPaymentDueDt]
                 , a.InvestorLoanId as [InvestorLoanId]
                 , a.InvestorPoolId as [InvestorPoolId]
                 , a.LoanStatusId as [LoanStatusId]
    FROM ???  )


    SELECT loanid as cteLoanId 
        FROM [spd].[claims].[Population] 
    WHERE id in (select id from ctePopulation)

很难猜出你想要什么......

• 最后缺少一个括号。
• 您应该在进行主选择之前定义“With”子句（cteLoadBase 在主选择之后定义）。
• 您缺少 FROM

Answer 2

只有在cte 定义完成后，您才应该select。该代码在 cte 定义之间有一个select。

 ;with cteClaims as (
select a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
  FROM [spd].[claims].[Population] a                    
  group by a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                   
  having a.ClaimStatus not in ('Closed', 'Denied', 'Paid')                  
  ), ctePopulation as (  
  select a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription                 
  FROM [spd].[claims].[Population] a                    
  join cteClaims b on a.LoanId = b.LoanId                   
  group by a.LoanId, a.ID, a.ClaimType, a.ClaimStatus, a.ClaimTypeDescription)  
 , cteLoanBase as ( ...)

 select loanid as cteLoanId 
 from [spd].[claims].[Population] where id in (select id from ctePopulation)

这里还要提到一件事：group by 被用于cte，尽管没有在任何列上使用聚合。应该避免这种情况。
