比如一个自由表,可以不移动指针取得某个记录的某个字段的值吗?
比如自由表“abc”的第5个记录、字段“neirong”的值。
谢谢

SQL 不会移动指针的啊。
又或者,你可以恢复指针。

你可以一次性存入数组,通过数组下标引用数据

这样的要求比较呆板。

Keep notes [url=http://www.mmopowerlevel.net]wow power leveling[/url] of how much a stack of resources (light leather from skinning, copper ore from mining,
silverleaf and [url=http://www.mogxe.com/PowerLevel.php?gid=1]wow power leveling[/url] peaceblossom from herbalism) sell to an NPC vendor
[url=http://www.mmopowerlevel.net/buy.php]wow gold uk[/url] but dont sell to the vendor. Check [url=http://www.mmopowerlevel.net/powerlist.php?fid=688]wow
power leveling[/url] the Auction House prices using the search facility and [url=http://www.mogxe.com/BuyGold.php?gid=21]aion kinah[/url] take note of the
starting and buyout prices for the stacks of resources you are selling. Many items [url=http://www.mogxe.com]wow power leveling[/url] have a buy-out price
upto 10-20 times [url=http://www.mmopowerlevel.net/powerlist.php?fid=7422]aion power level[/url] the price an NPC vendor will buy from you. I
[url=http://www.mogxe.com/PowerLevel.php?gid=21]aion power level[/url] personally set my prices as follows .... starting price 2x the NPC vendor buy value
(around 1.5-2.5s per stack) and [url=http://www.mogxe.com/PowerLevel.php?gid=21]aion powerleveling[/url] a buyout price 5-6 times the NPC buy value unless
all the competitor sellers buyout [url=http://www.mogxe.com/BuyGold.php?gid=1]buy wow gold[/url] prices are way above or below that, then I set my buyouts at
just below theirs.
