Question

您好我需要有关此代码语法的帮助：

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

收到错误：消息8155，级别16，状态1，行5 没有为'#LTS_MAP'的第2列指定列。

尝试将案例功能与选择的dtMicIssue结合起来并弄乱语法......

Answer 1

正是它所说的

每个列都需要您正在创建的表#LTS_MAP中的名称...

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 2

由于您正在执行SELECT INTO，因此SQL Server需要知道每列的名称。您的第二列（具有CASE的列）没有明确的名称。决定你想要什么，然后把

AS ColumnName

在结束END

的CASE之后立即

Answer 3

试试这个

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

Answer 4

您需要为CASE语句设置别名，以使其具有列名：

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
