//orcl為你的數(shù)據(jù)庫(kù)的sid
string user="scott";
string password="tiger";
connection conn= drivermanager.getconnection(url,user,password);
statement stmt=conn.createstatement(resultset.type_scroll_sensitive,resultset.concur_updatable);
string sql="select * from test";
resultset rs=stmt.executequery(sql);
while(rs.next()) {%>
您的第一個(gè)字段內(nèi)容為：<%=rs.getstring(1)%>
您的第二個(gè)字段內(nèi)容為：<%=rs.getstring(2)%>
<%}%>
<%out.print("數(shù)據(jù)庫(kù)操作成功，恭喜你/");%>
