我在SQL Server的存储过程中有以下查询：

SELECT  TLI.LESNumber
    ,COUNT(TLT.PL)
INTO #PWCM
FROM #tmpLESImport TLI
INNER JOIN tbl_LES L 
    on TLI.LESNumber=L.NUMB
WHERE ISNULL(L.DELT_FLAG,0)=0
    AND L.SCHL_PK=@SCHL_PK
    AND TLI.PL IS NOT NULL
    AND LEN(TLI.PL)>0
GROUP BY LESNumber 
HAVING COUNT(PL)>1

运行查询时，出现以下错误：

An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name.

谁能告诉我为什么？#PWCM在此查询之前不会出现在任何地方。
