将数据库表中的数据生成Insert脚本的存储过程（改版）

项目中用到需要把表中的数据生成Insert脚本，从网上搜到了个存储过程，但是在执行时报错，就修改调试通过

添加对字段名为SQL关键字或是字段名带空格的支持，同时忽略自增长字段数据。

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
