如何使用表名做为参数实现存储过程的设计

Answer 1

但是，可以利用系统的两个存储过程来实现。 CREATE Procedure GetHighByTeam @tableName nvarchar(20) ,@startDate nvarchar(20),@endDate nvarchar(20),@teamNo nvarchar(1) AS//功能：通过班次得到温度最高值 declare @sSql nvarchar(4000),@i int set @sSql = 'select 'set @i = 1while @i < 16beginset @sSql = @sSql + ltrim(convert(varchar(3), @i))+ ' AS Seq,tempDate,tempTime,p'+ltrim(convert(varchar(3), @i))+' AS Point From ' + @tableName set @sSql = @sSql + ' Where p'+ltrim(convert(varchar(3),@i)) + ' = ( Select Max(p'+ltrim(convert(varchar(3),@i))+')From'+@tableName+'Where teamNo = ' + @teamNo + ' and (TempDate between ' + @startDate + ' And '+@endDate+'))' set @sSql = @sSql + ' and teamNo =' + @teamNo set @sSql = @sSql + ' Union Select ' set @i = @i+1endset @sSql = @sSql + ltrim(convert(varchar(3), @i)) + ' AS Seq ,tempDate,tempTime,p'+ltrim(convert(varchar(3), @i)) + ' AS Point From ' + @tableName set @sSql = @sSql + ' Where p'+ltrim(convert(varchar(3), @i)) + '= (Select Max(p'+ltrim(convert(varchar(3), @i))+') From '+@tableName +' Where teamNo = ' + @teamNo + ' and (TempDate between ' + @startDate + ' And '+@endDate+'))' set @sSql = @sSql +' and teamNo =' + @teamNo EXECUTE sp_executesql @sSqlGO这个存储过程的实现大家可以不去考虑，只需要注意标红的地方，使用系统的存储过程 储过程的实现大家可以传递表名称，从而实现所需要的传递表名作为参数的需要。
