以下代码给了我这个抽象方法错误.谁能建议我如何使用jdbc获取默认数据库名称?

The following code gives me this abstract method error. Can anyone suggest me how I can get default database name using jdbc?

Exception in thread "main" java.lang.AbstractMethodError: com.teradata.jdbc.jdk6.JDK6_SQL_Connection.getSchema()Ljava/lang/String;

public class TestTDConnection {

    public static void main(String args[]) {

        String tdConnString = "jdbc:teradata://xx/database=xx";

        try {
            Connection conn = DriverManager.getConnection(tdConnString,"xx","xx");
            System.out.println(conn.getSchema());
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

推荐答案

如果您查看

If you look at the javadoc for getSchema(), you will notice the following:

由于:
1.7

Since:
1.7

这意味着您需要Java 7驱动程序，并且错误消息中的类名明显表明您正在使用Java 6驱动程序:

That means you need a Java 7 driver, and the classname in the error message is an obvious indication that you're using a Java 6 driver:

com.teradata.jdbc.jdk6.JDK6_SQL_Connection

用兼容Java 7(JDBC 4.1)的驱动程序替换驱动程序.jar文件.

Replace the driver .jar file with a Java 7 (JDBC 4.1) compliant driver.

或者不使用Java 7功能.

Or don't use Java 7 features.
