SQL写数据绑定生成

ALTER FUNCTION [dbo].[GenCode]
(
    @TbName NVARCHAR(200),@strFormat NVARCHAR(200)
)
RETURNS @Table TABLE (Code  nvarchar(4000))
as
BEGIN
    DECLARE @className NVARCHAR(200)

    IF(@TbName LIKE '%_%') BEGIN
        SET @className=RIGHT(@TbName,LEN(@TbName)-CHARINDEX('_',@TbName))
    END 
    INSERT INTO @Table ( Code )
SELECT  REPLACE(REPLACE(REPLACE(@strFormat,'{T}',@className),'{C}',c.name),'{N}',CAST( ISNULL(e.[value],'xxxx') AS NVARCHAR(200)))
 FROM sys.objects o
INNER JOIN sys.columns c ON o.object_id=c.object_id and o.Type='U' 
LEFT JOIN sys.extended_properties e on e.major_id=c.object_id and e.minor_id=c.Column_id and e.class=1 
WHERE o.type='U' AND o.name=@TbName
    
    RETURN 
END

接触一个项目,有几个表都是有好几十个字段,做数据绑定时太烦神了,花个几分钟写了个函数,批量生成下
