ACCESS有个BUG，那就是在使用 like 搜索时如果遇到日文就会出现“内存溢出”的问题，提示“80040e14/内存溢出”。
以前也遇到过了，不过那时没怎么在意把含有日文的数据删除了就好了，现在这次的都是些重要的资料不可能删除的，就需要想办法来解决了。
那导致出问题的26个日文：ゴ ガ ギ グ ゲ ザ ジ ズ ヅ デ ド ポ ベ プ ビ パ ヴ ボ ペ ブ ピ バ ヂ ダ ゾ ゼ
说一下解决办法：
1、最笨的方法：删除含有日文的数据
这就不用解释了；
2、替换方法：
思路：就是存储进入数据库时把那26个日文替换成别的编码，在从数据库取出来后在反替换回来；
从网上找了个现成的函数：
编码:
Function Jencode(byVal iStr)
if isnull(iStr) or isEmpty(iStr) then
Jencode=""
Exit function
end if
dim F,i,E
’ F=array("ゴ","ガ","ギ","グ","ゲ","ザ","ジ","ズ","ヅ","デ",_
’ "ド","ポ","ベ","プ","ビ","パ","ヴ","ボ","ペ","ブ","ピ","バ",_
’ "ヂ","ダ","ゾ","ゼ")
E=array("Jn0;","Jn1;","Jn2;","Jn3;","Jn4;","Jn5;","Jn6;","Jn7;","Jn8;",
"Jn9;","Jn10;","Jn11;","Jn12;","Jn13;","Jn14;","Jn15;","Jn16;","Jn17;",
"Jn18;","Jn19;","Jn20;","Jn21;","Jn22;","Jn23;","Jn24;","Jn25;")
F=array(chr(-23116),chr(-23124),chr(-23122),chr(-23120),_
chr(-23118),chr(-23114),chr(-23112),chr(-23110),_
chr(-23099),chr(-23097),chr(-23095),chr(-23075),_
chr(-23079),chr(-23081),chr(-23085),chr(-23087),_
chr(-23052),chr(-23076),chr(-23078),chr(-23082),_
chr(-23084),chr(-23088),chr(-23102),chr(-23104),_
chr(-23106),chr(-23108))
Jencode=iStr
for i=0 to 25
Jencode=replace(Jencode,F(i),E(i))
next
End Function
解码:
Function Juncode(byVal iStr)
if isnull(iStr) or isEmpty(iStr) then
Juncode=""
Exit function
end if
dim F,i,E
’ F=array("ゴ","ガ","ギ","グ","ゲ","ザ","ジ","ズ","ヅ","デ",_
’ "ド","ポ","ベ","プ","ビ","パ","ヴ","ボ","ペ","ブ","ピ","バ",_
’ "ヂ","ダ","ゾ","ゼ")
E=array("Jn0;","Jn1;","Jn2;","Jn3;","Jn4;","Jn5;","Jn6;","Jn7;","Jn8;",
"Jn9;","Jn10;","Jn11;","Jn12;","Jn13;","Jn14;","Jn15;","Jn16;",
"Jn17;","Jn18;","Jn19;","Jn20;","Jn21;","Jn22;","Jn23;","Jn24;","Jn25;")
F=array(chr(-23116),chr(-23124),chr(-23122),chr(-23120),_
chr(-23118),chr(-23114),chr(-23112),chr(-23110),_
chr(-23099),chr(-23097),chr(-23095),chr(-23075),_
chr(-23079),chr(-23081),chr(-23085),chr(-23087),_
chr(-23052),chr(-23076),chr(-23078),chr(-23082),_
chr(-23084),chr(-23088),chr(-23102),chr(-23104),_
chr(-23106),chr(-23108))
Juncode=iStr
for i=0 to 25
Juncode=replace(Juncode,E(i),F(i))’□
next
End Function
3、处理SQL语句：
不要使用like语句，举个例子：
会出问题的SQL： where title like ’%"&keyword&"%’
现在换成下面的就不会出现内存溢出了：where InStr(1,LCase(Title),LCase(’"&keyword&"’),0)<>0
问题应该可以解决。飞飞As.p技术乐园
