换个写法试试
<%
try{
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ");
}
catch(ClassNotFoundException e)
{
out.print( "类找不到! "+e);
}
try{
String url= "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs ";
//pubs 为你的数据库的
String user= "sa ";
String password= "6261046 ";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select job_id,job_desc from jobs ";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {
您的第一个字段内容为： <%=rs.getString(1)%> <br/>
您的第二个字段内容为： <%=rs.getString(2)%> <br/>
}
out.print( "数据库操作成功，恭喜你 ");
