为数据库生成某个字段充填随机数的存储过程

代码如下:

Declare @CurrentRecord int,@BeginNum int, @EndNum int, @TotalCount int,@Value int 
set @BeginNum=0 
set @EndNum=500 
set @TotalCount=80 
set @CurrentRecord=1 
While @CurrentRecord<=@TotalCount 
Begin 
set @Value= @BeginNum+(@EndNum - @BeginNum)*rand() 
update [tableName] set [columnName] = @Value where [IDColumnName] = @CurrentRecord 
set @CurrentRecord=@CurrentRecord+1 
End
