to 楼主:你这样好像会执行sql 多次……
其中$string可以是SQL SERVER存储过程的调用.这样就要自己写一个类似于limit的存储过程,在SQL SERVER他虽有TOP这项功能,但它的翻页,我们那时有个写VB的同事封装了一个用游标翻页的存储过程,由于年事以久,且不是自己封装的所一存储过程的代码找不见了,现在说一下调用过程,望能引发大家的一些思维:应该不是误导^_^
$string="exec web_ScrollPage 'fo03t001','complex,description,isroomreqd,isexcludegrp,isautoassign','complex,description,isroomreqd,isexcludegrp,isautoassign',".$PAGE_ROWS.",".$AddValue;
exec web_ScrollPage 'fo03t001',---这一段是掉用存储过程,及所要访问的table
'complex,description,isroomreqd,isexcludegrp,isautoassign',----要读的字段
'complex,description,isroomreqd,isexcludegrp,isautoassign',----存储过程中建立临时表所要的字段
".$PAGE_ROWS.",".$AddValue-----每页的行数,及开始的位置在存储过程中是先建临时表,移游标到$AddValue所在的位置,然后移动游标一条条将记录读到临时表里,最后再读一次临时,删掉临时表,就这样是不是很烦.
不过在读大量数据是用数组翻页就不如这样了^_^
是呀,我在忙着呢,没细看:(
