ASP處理多關鍵詞查詢

在web開發中經常遇到多關鍵詞對對單個欄位查詢，我一般是通過動態數組來實現的。當然多個關鍵詞的一般是用空格或,隔開，我這幾假設多個關鍵詞用空格隔開,關鍵字字串為keyStr，具體代碼為。

'多關鍵字的搜尋
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
