将数据库表中的数据生成Insert脚本的存储过程

工作中遇到租用别的的服务器，操作sql是件很头痛的事，有的管理员什么也不让你做，有时真急人！
下面这个存储过程就是把一个数据表里的数据生成insert语句，这样就好多了！！

CREATE Procedure DBGenData
    @tableName Varchar(100)--表名
AS
    DECLARE @IsIdentity INT
    DECLARE @columnName VARCHAR(100)--列名
    DECLARE @TypeName VARCHAR(100)--数据类型
    DECLARE @columns VARCHAR(3000)--
    DECLARE @columnsAndhead VARCHAR(3000)--

    SET @columnsAndhead = \'INSERT INTO \'+@tableName+\'([\'
    SET @columns = \'\'

    --获取表的所有字段名称
    DECLARE a CURSOR FOR
        SELECT COLUMNPROPERTY( a.id,a.name,\'IsIdentity\') AS IsIdentity, a.[NAME] AS ColumnName ,b.[NAME] AS TypeName
        FROM syscolumns a INNER JOIN systypes b ON a.xtype=b.xtype AND b.xtype=b.xusertype
        WHERE a.[id]=(SELECT [id] FROM sysobjects WHERE [NAME]=@tableName)

    OPEN a

    FETCH NEXT FROM a INTO @IsIdentity, @columnName ,@TypeName
        WHILE @@FETCH_STATUS = 0
            BEGIN
                IF @IsIdentity =0
                    BEGIN
                        IF @TypeName IN (\'bigint\',\'bit\',\'decimal\',\'float\',\'int\',\'money\',\'numeric\',\'real\',\'smallint\',\'smallmoney\',\'tinyint\')
                            BEGIN
                                SET @columns = @columns + \'ISNULL(CAST([\'+@columnName +\'] AS VARCHAR),\'\'NULL\'\')+\'\',\'\'+\'
                            END
                        ELSE
                            BEGIN
                                SET @columns = @columns+ \'\'\'\'\'\'\'\'\'+ ISNULL(CAST([\'+@columnName +\'] AS VARCHAR),\'\'NULL\'\')+ \'\'\'\'\'\'\'\'+\'\',\'\'+\'
                            END
                        SET @columnsAndhead = @columnsAndhead + \'\'+ @columnName +\'],[\'
                    END
                FETCH NEXT FROM a INTO @IsIdentity, @columnName ,@TypeName
             END

SELECT @columnsAndhead = left(@columnsAndhead,len(@columnsAndhead)-2) +\') VALUES(\'\'\'
SELECT @columns = left(@columns,len(@columns)-5)

CLOSE a
DEALLOCATE a

exec(\'select \'\'\'+@columnsAndhead+\'+\'+@columns +\'+\'\')\'\' as InsertSQL from \'+@tableName)

GO
