在选择查询中合并两个SQL脚本使用(如果条件)

sql

我有2个脚本,如下所示:

第一:

SELECT [Fm].[Id], [Sdp].[FirstName], [Sdp].[LastName], [Sdp].[SSN],
[Sdp].[StoreName], [Sdp].[PostalCode], [Fc].[Id], [Sdp].[Address]
FROM [SRM].[SiteMembers].[DProfile] AS [Sdp]
INNER JOIN [SRM].[SiteMembers].[Member] AS [Sm]
ON [Sdp].[Member_Id] = [Sm].[Id]
INNER JOIN [FRM].[Members].[Member] AS [Fm]
ON [Sm].[UserId] = [Fm].[UserId]
INNER JOIN [SRM].[General].[City] AS [Sc]
ON [Sdp].[City_Id]=[Sc].[Id]
INNER JOIN [FRM].[General].[City] AS [Fc]
ON [Fc].[Title]=[Sc].[Title] 
COLLATE SQL_Latin1_General_CP1_CI_AS
WHERE ISNUMERIC([Sdp].[PostalCode])=1;

第二个:

SELECT [Fm].[Id], [Sdp].[FirstName], [Sdp].[LastName], [Sdp].[SSN],
[Sdp].[StoreName], 0, [Fc].[Id], [Sdp].[Address]
FROM [SRM].[SiteMembers].[DProfile] AS [Sdp]
INNER JOIN [SRM].[SiteMembers].[Member] AS [Sm]
ON [Sdp].[Member_Id] = [Sm].[Id]
INNER JOIN [FRM].[Members].[Member] AS [Fm]
ON [Sm].[UserId] = [Fm].[UserId]
INNER JOIN [SRM].[General].[City] AS [Sc]
ON [Sdp].[City_Id]=[Sc].[Id]
INNER JOIN [FRM].[General].[City] AS [Fc]
ON [Fc].[Title]=[Sc].[Title] 
COLLATE SQL_Latin1_General_CP1_CI_AS
WHERE ISNUMERIC([Sdp].[PostalCode])=0;

这2个脚本之间的区别在于,第一个脚本选择带有数字邮政编码的列,第二个脚本选择非数字邮政编码的0,所以我如何将这2个脚本合并到一个脚本中,我不是在谈论Union,我很有趣在非数字邮政编码的选择查询中使用某些条件时,请选择0。任何人有任何想法吗?

case在选定的列列表中使用一条语句,然后删除该where子句:

SELECT [Fm].[Id], [Sdp].[FirstName], [Sdp].[LastName], [Sdp].[SSN],
[Sdp].[StoreName],
case when isnumeric([Sdp].[PostalCode]) = 1 then [Sdp].[PostalCode] else 0 end,
[Fc].[Id], [Sdp].[Address]
FROM [SRM].[SiteMembers].[DProfile] AS [Sdp]
INNER JOIN [SRM].[SiteMembers].[Member] AS [Sm]
ON [Sdp].[Member_Id] = [Sm].[Id]
INNER JOIN [FRM].[Members].[Member] AS [Fm]
ON [Sm].[UserId] = [Fm].[UserId]
INNER JOIN [SRM].[General].[City] AS [Sc]
ON [Sdp].[City_Id]=[Sc].[Id]
INNER JOIN [FRM].[General].[City] AS [Fc]
ON [Fc].[Title]=[Sc].[Title] 
COLLATE SQL_Latin1_General_CP1_CI_AS
