对一个透视表进行分组

Question

我想将下表分为两个范围。为此，我转动了表格，但它显示了一些NULL字段。我如何对表进行分组，以便只向我显示非空值？

这是SQL查询：

SELECT RangoCuotas, [0   -21  ],[21  -42  ],[42  -79  ],[79  -158 ],[158  -9999]
FROM(
    SELECT IdTasaSeguro, Valor, CONVERT(CHAR(4),MontoMinimo)+'-'+CONVERT(CHAR(4),MontoMaximo) AS RangoMonto, CONVERT(CHAR(4),CASE WHEN CuotaMin = 0 THEN 1 ELSE CuotaMin END)+'-'+CONVERT(CHAR(4),CuotaMax) AS RangoCuotas
    FROM [BEFE_SistemaGestionMDP].[dbo].[TasaSeguro]
    WHERE IdTipoSeguro = 1
) AS SourceTable
PIVOT 
(
SUM(Valor) FOR RangoMonto IN ([0   -21  ],[21  -42  ],[42  -79  ],[79  -158 ],[158 -9999])
) AS PivotTable1
GROUP BY RangoCuotas,[0   -21  ],[21  -42  ],[42  -79  ],[79  -158 ],[158 -9999]

Answer 1

如果您使用SELECT作为主(...) SourceTable语句，那么您就会看到原因。

解决方案：从IdTasaSeguro派生的表中删除不必要的列（例如FROM( SELECT Valor, CONVERT(CHAR(4),MontoMinimo)+'-'+CONVERT(CHAR(4),MontoMaximo) AS RangoMonto, CONVERT(CHAR(4),CASE WHEN CuotaMin = 0 THEN 1 ELSE CuotaMin END)+'-'+CONVERT(CHAR(4),CuotaMax) AS RangoCuotas FROM [BEFE_SistemaGestionMDP].[dbo].[TasaSeguro] WHERE IdTipoSeguro = 1 ) AS SourceTable ）
