在web开发中经常遇到多关键词对对单个字段查询，我一般是通过动态数组来实现的。当然多个关键词的一般是用空格或,隔开，我这几假设多个关键词用空格隔开,关键字字符串为keyStr，具体代码为。

程序代码：

关键字的搜索
str="select * from tableName where id>4"
if srhKey<>"" then
keyArr=split(srhKey," ")
j=UBound(keyArr)
t=0
dim keystrArr()
for i=0 to j
if keyArr(i)<>"" then
redim preserve keystrArr(t)
strfilter="(empZw like %"&keyArr(i)&"% or empDep like %"&keyArr(i)&"% or empGz like %"
strfilter=strfilter&keyArr(i)&"% or empWy1 like %"&keyArr(i)&"% or empWy2 like %"&keyArr(i)
strfilter=strfilter&"% or empYq like %"&keyArr(i)&"% or com_name like %"&keyArr(i)&"%)"
keystrArr(t)=strfilter
t=t+1
end if
next
keystr=join(keystrArr," and ")
str=str&" and "&keystr
end if
