web開發(fā)中經(jīng)常遇到多關(guān)鍵詞對單個字段的查詢，我們一般是通過動態(tài)數(shù)組來實(shí)現(xiàn)的。當(dāng)然多個關(guān)鍵詞的一般是用空格或,隔開，本文假設(shè)多個關(guān)鍵詞用空格隔開,關(guān)鍵字字符串為keyStr，具體代碼為。

程序代碼：

以下為引用的內(nèi)容：

'關(guān)鍵字的搜索
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
