要在Connection对象conn上创建Statement对象,可以使用________: Statement statement = Connection.createStatement();|Statement statement = conn.createStatement();|Statement statement = conn.statement();|Statement statement = connection.create();

以下语句可以创建Statement接口对象的是（ ） A: Statement sm = new Statement() B: Statement sm = conn. createStatement(); （注：conn为数据连接对象） C: Statement sm = conn. getStatement ();（注：conn为数据连接对象） D: Statement sm = conn. prepareStatement ();（注：conn为数据连接对象）

以下语句可以创建Statement接口对象的是（ ）（注：conn为数据连接对象） A: Statement sm = new Statement() B: Statement sm = conn. createStatement(); C: Statement sm = conn. getStatement (); D: Statement sm = conn. prepareStatement ();

现在已经有一个Connection类的对象conn，建立一个Statement对象stat的语句是：__________________。

建立一个Connection对象的正确方法是( )。 A: Dim conn As ADODB.Connection conn=ADODB.Connection B: Dim conn As ADODB.Connection Set conn=New ADODB.Connection C: Dim conn As ADODB.Connection Set conn=ADODB.Connection D: Dim conn As Connection Set conn=New Connection

建立一个Connection对象的正确方法是( )。 A: Dim conn As ADODB.Connection<br>conn=ADODB.Connection B: Dim conn As ADODB.Connection<br>Set conn=New ADODB.Connection C: Dim conn As ADODB.Connection<br>Set conn=ADODB.Connection D: Dim conn As Connection<br>Set conn=New Connection

编写一个程序，查询Access数据库Database1中Student表中的信息，其中数据库Database1对应的数据源为myData。 import java.sql.*; public class DataDemo { public static void main(String args[]) throws Exception { Class.forName(______(1)_______); //加载JDBC-ODBC驱动程序 Connection conn = DriverManager.getConnection(_____(2)____,””,””); //连接ODBC数据源myData Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery(____(3)_____); //返回Student表所有行 while (rs.next()) { System.out.println(rs.getString(2)); } if (rs!=null)) rs.close(); if(stmt!=null) ____(4)_____; //关闭stmt对象 if(conn!=null) ____(5)_____; //关闭conn对象 } }

如果SqlConnection对象为conn,SqlCommand对象为cmd,请写出将cmd的连接属性设置为conn的代码:______

连接对象的创建方法中，正确的是（）。 A: Conn=CreateObjet（“ADODConnection”） B: Conn=Server.CreateObjet（“ADODConnection”） C: SetConn=Server.CreateObjet（“ADODConnection”） D: SetConn=Server.CreateObjet（ADODConnection）

The CORRECT data flow from one financial statement to the next is: A: statement of retained earnings, income statement, balance sheet, statement of cash flows. B: balance sheet, statement of retained earnings, income statement, statement of cash flows. C: statement of retained earnings, income statement, statement of cash flows, balance sheet. D: income statement, statement of retained earnings, balance sheet, statement of cash flows.
