How to set the initial value of an auto-incremented column in MySQL using JDBC?

While creating a table, in certain scenarios, we need values to column such as ID, to be generated/incremented automatically. Various databases support this feature in different ways.
In MySQL database you can declare a column auto increment using the following syntax.
CREATE TABLE table_name(
   ID INT PRIMARY KEY AUTO_INCREMENT,
   column_name1 data_type1,
   column_name2 data_type2,
   column_name3 data_type3,
   column_name4 data_type4,
   ............ ...........
);
While inserting records in a table there is no need to insert value under the auto-incremented column. These will be generated automatically.
By default, the initial value of the auto-incremented column will be 1. You can change it using the ALTER TABLE query as shown below −
alter table table_name AUTO_INCREMENT = 1001
Let us create a table with name sales in MySQL database, with one of the columns as auto-incremented, using CREATE statement as shown below −
CREATE TABLE Sales(
   ID INT PRIMARY KEY AUTO_INCREMENT,
   ProductName VARCHAR (20),
   CustomerName VARCHAR (20),
   DispatchDate date,
   DeliveryTime time,
   Price INT,
   Location VARCHAR(20)
);
Following JDBC program sets the initial value of the auto-incremented column to 1001 and inserts 6 records into it.
import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class SettingInitialValue_AutoIncrement_Pstmt {
   public static void main(String args[]) throws SQLException {
      //Registering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/sample_database";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
      System.out.println("Connection established......");
      //Setting the initial value of the auto-incremented column
      Statement stmt = con.createStatement();
      stmt.execute("alter table Sales AUTO_INCREMENT = 1001");
      //Query to Insert values to the sales table
      String insertQuery = "INSERT INTO Sales (ProductName, CustomerName, DispatchDate, DeliveryTime, Price, Location) VALUES (?, ?, ?, ?, ?, ?)";
      //Creating a PreparedStatement object
      PreparedStatement pstmt = con.prepareStatement(insertQuery,Statement.RETURN_GENERATED_KEYS);
      pstmt.setString(1, "Key-Board");

      pstmt.addBatch();
      pstmt.setString(1, "Earphones");

      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.addBatch();
      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.addBatch();
      System.out.println("Records inserted......");
      //Executing the batch
      pstmt.executeBatch();
   }
}
Connection established......
Records inserted......
If you verify the contents of the Sales table using SELECT statement, you can see the inserted records with ID value starting from 1001 as −
mysql> select * from sales;
