TSQL情況下語法

Question

您好我需要這個代碼的語法幫助：

IF OBJECT_ID('TEMPDB..#LTS_MAP') IS NOT NULL 
BEGIN DROP TABLE #LTS_MAP END 


SELECT 
dtMicIssue as LATE_CHARGE_FACTOR 
,CASE 
WHEN (dtMicIssue is NOT NULL) AND (dtMicIssue <> '1900-01-01 00:00:00') 
THEN CONVERT(SMALLDATETIME,dtMicIssue) 
    ELSE NULL END 


INTO #LTS_MAP 
FROM SBAURSQL001.LTSArchive.dbo.LoanMaster_0609 

receiving error: Msg 8155, Level 16, State 1, Line 5 No column was specified for column 2 of '#LTS_MAP'.

嘗試情況下的功能與選擇的dtMicIssue的和語法搞亂結合...

Answer 1

您需要別名CASE語句，以便它有一個列名：

IF OBJECT_ID('TEMPDB..#LTS_MAP') IS NOT NULL 
BEGIN DROP TABLE #LTS_MAP END 


SELECT 
dtMicIssue as LATE_CHARGE_FACTOR 
,CASE 
WHEN (dtMicIssue is NOT NULL) AND (dtMicIssue <> '1900-01-01 00:00:00') 
THEN CONVERT(SMALLDATETIME,dtMicIssue) 
    ELSE NULL END AS DATE 


INTO #LTS_MAP 
FROM SBAURSQL001.LTSArchive.dbo.LoanMaster_0609 

Answer 2

正是它說

每列需要在你所創建表#LTS_MAP姓名...

SELECT 
dtMicIssue as LATE_CHARGE_FACTOR 
,CASE 
WHEN (dtMicIssue is NOT NULL) AND (dtMicIssue <> '1900-01-01 00:00:00') 
THEN CONVERT(SMALLDATETIME,dtMicIssue) 
    ELSE NULL END AS SomethingMeaningfulHere --you're missing this: a column name! 


INTO #LTS_MAP 
FROM SBAURSQL001.LTSArchive.dbo.LoanMaster_0609 

Answer 3

既然你正在做一個SELECT INTO，SQL Server需要知道每列的名稱。您的第二列（與CASE一起）沒有明確的名稱。決定你想叫什麼，然後把

AS ColumnName 

表示結束CASE

Answer 4

試試這個

SELECT dtMicIssue as LATE_CHARGE_FACTOR, 
    CASE WHEN (dtMicIssue is NOT NULL) AND 
      (dtMicIssue <> '1900-01-01 00:00:00') 
     THEN CONVERT(SMALLDATETIME,dtMicIssue) 
     ELSE NULL END As SomeColumnName 

INTO #LTS_MAP 
FROM SBAURSQL001.LTSArchive.dbo.LoanMaster_0609
