我正在使用 sql 存储过程编写基于参数的报告。问题是有几个“可选”参数，用户可以在其中选择一个值，或者完全忽略该参数。我需要将存储的过程用作 asp.net 报告中的数据集。我想到的唯一方法是从结果中创建一个表。但我一无所知。

如何将其转换为“创建表”存储过程？非常感谢任何帮助。

这是我到目前为止所拥有的 -

ALTER PROCEDURE [dbo].[rspSCL]

@RRID as int,
@State as nchar(2),
@Sub as varchar(75),

@thirdapp as bit)

DECLARE @SQL as varchar(4000)

--what fields need to be seen
SET @SQL = 'SELECT C.CRID, C.DOT, C.RR, C.Pref, C.MP, C.Division,  C.Subdivision,C.City, C.Street,
