这段代码怎么解释
可以为我解读下面这段代码么,不是很明白,特别是红色部分的代码,不知道有什么作用!for i=0 to ubound(keywordlist)
keywordlist(i) = Trim(keywordlist(i))
sql=sql &" WEBSITE.title like '%" & keywordlist(i) & "%' or "
sql=sql &" WEBSITE.keyword like '%" & keywordlist(i) & "%' or "
sql=sql &" like '%" & keywordlist(i) & "%' or "
sql=sql &" WEBSITE.url like '%" & keywordlist(i) & "%' or "
Next
sql=Left(sql,(LEN(sql)-3))
search_sql="1=1 and ("&sql&") order by click desc"
rs.open "SELECT ID,TITLE,URL,COMMENT FROM WEBSITE WHERE "&search_sql,conn,1,1
