自定义 sql Split函数 / 自定义mp_helptext查看存储

1. 分割函数：

    --Split 表函数将一个字符串按指定分隔符进行分割，返回一个表。  
    create function split(  
        @string varchar(255),--待分割字符串  
        @separator varchar(255)--分割符  
    )returns @array table(item varchar(255))  
    as  
    begin  
        declare @begin int,@end int,@item varchar(255)  
        set @begin = 1  
        set @end=charindex(@separator,@string,@begin)  
        while(@end<>0)  
        begin  
            set @item = substring(@string,@begin,@end-@begin)  
            insert into @array(item) values(@item)  
            set @begin = @end+1  
            set @end=charindex(@separator,@string,@begin)  
        end  
        set @item = substring(@string,@begin,len(@string)+1-@begin)  
        if (len(@item)>0)  
            insert into @array(item) values(substring(@string,@begin,len(@string)+1-@begin))  
        return  
    end

2005 以上版本XQuery

create function func_splitid
(@str varchar(max),@split varchar(10))
RETURNS @t Table (c1 int)
AS
BEGIN
    DECLARE @x XML
    SET @x = CONVERT(XML,'<items><item id="' + REPLACE(@str, @split, '"/><item id="') + '"/></items>')
    INSERT INTO @t SELECT x.item.value('@id[1]', 'INT') FROM @x.nodes('//items/item') AS x(item)
    RETURN 
END

执行结果:

2. mp_helptext

    create procedure mp_helptext(  
        @name varchar(255)  
    )  
    as  
    declare @object_id int,  
                    @sourcecode varchar(max),  
                    @line varchar(max),  
                    @end int,  
                    @rn varchar(2),  
                    @tab varchar(1)  
                      
    declare @source table(  
        source varchar(max)  
    )  
      
    set @rn = char(13)+char(10)  
    set @tab = char(9)  
      
      
    select @sourcecode = definition from sys.sql_modules where object_id=object_id(@name)  
      
    while(charindex(@rn,@sourcecode)!=0)  
    begin  
        set @end=charindex(@rn,@sourcecode)  
        set @line = replace(substring(@sourcecode,1,@end-1),@tab,@tab+@tab)  
        if(charindex('create',@line)<>0 and (charindex('proc',@line)<>0 or charindex('view',@line)<>0 or charindex('function',@line)<>0 or charindex('trigger',@line)<>0))  
        begin  
            set @line = replace(@line,'create','alter')  
        end  
        insert into @source(source) values(@line)  
        set @end = @end + 2  
        set @sourcecode = substring(@sourcecode,@end,len(@sourcecode))  
    end  
    insert into @source(source) values(@sourcecode)  
      
    select * from @source
