sql把字符數組轉換成表

需求：把字符串1,2,3變成表里的行數據

方法：用自定義函數實現

/*
       獲取字符串數組的 Table
*/
if exists (select 1 from sysobjects where id = object_id('Get_StrArrayStrOfTable' ))
   drop Function Get_StrArrayStrOfTable
go
CREATE function Get_StrArrayStrOfTable(
       @SourceSql varchar (max),
       @StrSeprate varchar (10)
)
returns @temp table( F1 varchar (100))
as
begin
       declare @i int
       set @SourceSql =rtrim( ltrim(@SourceSql ))
       set @i =charindex( @StrSeprate,@SourceSql )
       while @i >=1
       begin
             insert @temp values(left( @SourceSql,@i -1))
             set @SourceSql =substring( @SourceSql,@i +1, len(@SourceSql )-@i)
             set @i =charindex( @StrSeprate,@SourceSql )
       end
      
       if @SourceSql <>''
             insert @temp values( @SourceSql)
            
       return
end
GO

用法：

SELECT * from dbo.Get_StrArrayStrOfTable('1,2,3',',')
