自动生成INSERT语句的SQL存储过程

这是建立一个存储过程，通过执行这个存储过程，将指定的数据表中的数据导成Insert语句形式 无 CREATE PROCEDURE #usp_GenInsertSql (@tablename VARCHAR(256))AS BEGIN DECLARE @sql VARCHAR(MAX) DECLARE @sqlValues VARCHAR(MAX) SET @sql =' (' SET @sqlVa

 CREATE PROCEDURE #usp_GenInsertSql (@tablename VARCHAR(256))
AS
 BEGIN
 DECLARE @sql VARCHAR(MAX)
 DECLARE @sqlValues VARCHAR(MAX)

 SET @sql =' ('
 SET @sqlValues = 'values (''+'

 SELECT @sqlValues = @sqlValues + cols + ' + '','' + ',
 @sql = @sql + QUOTENAME(name) + ','
