DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)
DECLARE @DynamicQuery AS NVARCHAR(MAX)

--Get distinct values of the PIVOT Column 
SELECT @ColumnName= ISNULL(@ColumnName + ',','') 
       + QUOTENAME(CovCode)
FROM (SELECT  distinct
    CovCode

 FROM Construct.dbo.View_Claim_SummaryPTS4PTS5Diamond where system in (4,5)) AS ClaimSummary

--Prepare the PIVOT query using the dynamic 
SET @DynamicPivotQuery = 
  N'SELECT vehicleid, ' + @ColumnName + '
    FROM Construct.dbo.View_Claim_SummaryPTS4PTS5Diamond
    PIVOT(max(Claim_Exp_Nbr) 
          FOR CovCode IN (' + @ColumnName + ')) AS PVTTable'

Set @DynamicQuery = 'Select * into #tmpcde from openrowset(''SQLNCLI'', ''Server=HPL-DSQL2\HPLDSQL2;Trusted_Connection=yes;'', '''Exec @DynamicPivotQuery''')'
exec (@DynamicQuery)

Select * from #tmpcde

我想你想要这样：

Set @DynamicQuery = 'Select * into #tmpcde from openrowset(''SQLNCLI'', ''Server=HPL-DSQL2\HPLDSQL2;Trusted_Connection=yes;'', '''+@DynamicPivotQuery+''')';
