在Java 中执行下面SQL语句没有响应,DEBUG 无法跟踪代码,但此语句在SQL DEVELOPER 执行没问题,在Java代码中执行其他 SQL 语句基本也没问题。
insert into T1 (ID, VALUE) select ID, VALUE from T2
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import oracle.jdbc.driver.OracleDriver;
public class TestOracleUtil {
public static void main(String[] args) throws SQLException { String sql = "insert into T1 (ID, VALUE) select ID, VALUE from T2"; update(getConnection(), sql); } public static Connection getConnection() { new OracleDriver(); String serverName = "192.168.1.3"; String portNumber = "1521"; String sid = "ORCL"; String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid; String username = "test"; String password = "test"; try { Connection conn = DriverManager.getConnection(url, username, password); return conn; } catch (SQLException e) { e.printStackTrace(); return null; } } static void update(Connection conn, String sql) throws SQLException{ Statement smt = conn.createStatement(); smt.executeUpdate(sql); }
