Question

任何人都可以帮助我吗？我收到了语法错误＆＃34; Msg 102，Level 15，State 1，Line 26语法不正确＆＃39; =＆＃39;。＆＃34;

    {Insert Into [Mortgage_CDriveDW].[dbo].[Dim_LoanX]
    ([Loan_ID],
    [LoanDate],
    [LoanYear],
    [LoanMonth],
    [LoanWeek])}

        {Select Distinct
        [Loan_ID] = CAST(ISNULL([Loan_ID], -1) As Int),
        [LoanDate] = CAST(ISNULL([LoanDate], '01/01/1900')  As Date), 
        CONVERT(INT,DATEPART(YEAR,[LoanDate])) As [LoanYear] = CAST(ISNULL(CONVERT(INT,DATEPART(YEAR,[LoanDate])) As [LoanYear] -1) As Int),
    CONVERT(INT,DATEPART(MONTH,[LoanDate])) As [LoanMonth] = CAST(ISNULL(MONTH,[LoanDate], -1) As Int),
    CONVERT(INT,DATEPART(WEEK,[LoanDate]))  As [LoanWeek] = CAST(ISNULL(WEEK,[LoanDate], -1) As Int)
    From            [dbo].[ODS]}

{SET IDENTITY_INSERT [Mortgage_CDriveDW].[dbo].[Dim_LoanX] ON
GO
Insert Into [Mortgage_CDriveDW].[dbo].[Dim_LoanX]
(               [Loan_Key],
                [Loan_ID],
                [LoanDate],
                [LoanYear],
                [LoanMonth],
                [LoanWeek]
)
Select  -1, -1, -1, -1, -1 
SET IDENTITY_INSERT [Mortgage_CDriveDW].[dbo].[Dim_LoanX] OFF
GO}

我还尝试使用Set Identity_Insert ON / OFF在插入和尺寸加载期间考虑空值。 ODS表将LoanYear / Month / Week作为空值，我使用convert和datepart在列中插入值。这是插入加载到Dim_LoanX表时抛出错误的地方。

Answer 1

这样的行是无效的语法

CONVERT(INT,DATEPART(YEAR,[LoanDate])) As [LoanYear] = CAST(ISNULL(CONVERT(INT,DATEPART(YEAR,[LoanDate])) As [LoanYear] -1) As Int)

有两种语法可用于在查询中定义列

1 AS Col1

或 Col1 = 1

你们俩都有

＆＃39; =＆＃39;附近的语法错误不正确
