如何使用JDBC API从Oracle数据库中删除表？
您可以使用INSERT查询将记录插入表中。
语法
INSERT INTO TABLE_NAME (column1, column2, column3,...columnN) VALUES (value1, value2, value3,...valueN); Or, INSERT INTO TABLE_NAME VALUES (value1, value2, value3,...valueN);
要使用JDBCAPI将记录插入数据库的表中，您需要-
注册驱动程序：使用DriverManager 类的 registerDriver()方法注册驱动程序类。将驱动程序类名称作为参数传递给它。
建立连接：使用DriverManager 类的getConnection()方法连接到数据库。将URL（字符串），用户名（字符串），密码（字符串）作为参数传递给它。
创建语句：使用Connection 接口的createStatement()方法创建一个Statement对象。
执行查询：使用executeUpdate()Statement接口的方法执行查询。
让我们使用CREATE语句在Oracle数据库中创建一个带有名称调度 的表，如下所示-
CREATE TABLE dispatches( PRODUCTNAME VARCHAR2(20), CUSTOMERNAME VARCHAR2(20), DISPATCHDATE DATE, DELIVERYTIME TIMESTAMP(6), PRICE NUMBER(38), LOCATION VARCHAR2(20) );
以下JDBC程序建立与Oracle数据库的连接，并在Dispatches表中插入5条记录-
示例
import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Time;
public class InsertData_Oracle {
public static void main(String args[]) throws SQLException {
//注册驱动程序
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
//获得连接
String oracleUrl = "jdbc:oracle:thin:@localhost:1521/xe";
Connection con = DriverManager.getConnection(oracleUrl, "system", "password");
System.out.println("Connection established......");
//将值插入表格
String query = "INSERT INTO dispatches VALUES (?, ?, ?, ?, ?, ?)";
PreparedStatement pstmt = con.prepareStatement(query);
pstmt.setString(1, "Key-Board");
pstmt.setString(2, "Raja");
pstmt.setDate(3, new Date(1567315800000L));
pstmt.setTime(4, new Time(1567315800000L));
pstmt.setInt(5, 7000);
pstmt.setString(6, "Hyderabad");
pstmt.execute();
pstmt.setString(1, "Earphones");
pstmt.setString(2, "Roja");
pstmt.setDate(3, new Date(1556688600000L));
pstmt.setTime(4, new Time(1556688600000L));
pstmt.setInt(5, 2000);
pstmt.setString(6, "Vishakhapatnam");
pstmt.execute();
pstmt.setString(1, "Mouse");
pstmt.setString(2, "Puja");
pstmt.setDate(3, new Date(1551418199000L));
pstmt.setTime(4, new Time(1551418199000L));
pstmt.setInt(5, 3000);
pstmt.setString(6, "Vijayawada");
pstmt.execute();
pstmt.setString(1, "Mobile");
pstmt.setString(2, "Vanaja");
pstmt.setDate(3, new Date(1551415252000L));
pstmt.setTime(4, new Time(1551415252000L));
pstmt.setInt(5, 9000);
pstmt.setString(6, "Chennai");
pstmt.execute();
pstmt.setString(1, "Headset");
pstmt.setString(2, "Jalaja");
pstmt.setDate(3, new Date(1554529139000L));
pstmt.setTime(4, new Time(1554529139000L));
pstmt.setInt(5, 6000);
pstmt.setString(6, "Goa");
pstmt.execute();
System.out.println("Records inserted......");
}
}输出结果
Connection established...... Records inserted......
如果使用select语句验证分发表的内容，则可以在其中找到插入的记录，如下所示：
SQL> select * from dispatches; PRODUCTNAME CUSTOMERNAME DISPATCHDATE DELIVERYTIME PRICE LOCATION ------------------------------------------------------------------------------------------ Key-Board Raja 01-SEP-19 01-SEP-19 11.00.00.000000 AM 7001 Hyderabad Earphones Roja 01-MAY-19 01-MAY-19 11.00.00.000000 AM 2000 Vishakhapatnam Mouse Puja 01-MAR-19 01-MAR-19 10.59.59.000000 AM 3000 Vijayawada Mobile Vanaja 01-MAR-19 01-MAR-19 10.10.52.000000 AM 9001 Chennai Headset Jalaja 06-APR-19 06-APR-19 11.08.59.000000 AM 6000 Goa
