Question

SQL与java问题

编译java程序;
mport java.sql.*;

public class TestSQLServer {
public static void main(String[] args) {
try {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Connection con = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://127.0.0.1:1433", "yht", "yht");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("select * from mytable1");

while (rs.next()) {
System.out.print("sid：" + rs.getInt(1));
System.out.print("\tname：" + rs.getString(2).trim());
System.out.print("\tsex：" + rs.getString(3).trim());
System.out.println();
}
rs.close();
stmt.close();
con.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}

出现错误:

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
at com.microsoft.jdbc.base.BaseExceptions.createException(Unknown Source)

是什么原因啊?

Answer 1

con = DriverManager.getConnection("jdbc:odbc:Driver={SQL Server};server=127.0.0.1;database=pubs","yht", "yht");

stmt=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);

catch(SQLException e)
{e.printStackTrace();}

Answer 2

jdbc中的数据库连接没有创建成功啊。可能是你的sql server的sp4补丁没有安装吧。

Answer 3

Connection con = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://127.0.0.1:1433", "yht", "yht");
有问题？？/！！！！！
