Temporary tables are created in tempdb. The name "temporary" is slightly misleading, for even though the tables are instantiated in tempdb and backed by physical disk and are even logged into the transaction log. They act like regular tables i
SqlServer循环语句 declare @i int set @i =1 while(@i<5) begin set @i = @i+1 insert into text(id,name) values('1','王麻子') end SqlServer批量倒数据 如果两张表字段相同的话: insert into text1 select * from text如果两张表字段不同的话: insert into text1(fid,fname,fage...) select fid,fnam
有两个著名的是:ipairs和pairs,双方都认为,我们都非常熟悉的.其中ipairs刮(idx=1)从明年序遍历,经验nil那退出循环:和pairs遍历,仅仅要里面有值都能够遍历的到. 那假如我须要顺序遍历并且即使中间有nil也能完整遍历到最后呢? 接下来就说这个:通过maxSize = table.maxn(pTable)获取到table最后一个元素的所在位置(或理解为最大长度.包含当中的nil).然后: for idx=1, maxSize do if pTable[idx] ~= ni
