How to insert only a single column into a MySQL table with Java?

Use INSERT INTO statement in the Java-MySQL connection code to insert a column.

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Name varchar(20)
   -> );
Query OK, 0 rows affected (0.54 sec)

Here is the Java code to insert only a single column into a MySQL table.

Example

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class InsertOneColumnDemo {
   public static void main(String[] args) {
      Connection con = null;
      PreparedStatement ps = null;
      try {
         con = DriverManager.getConnection("jdbc:mysql://localhost:3306/web?" + "useSSL=false", "root", "123456");
         String query = "insert into DemoTable(Name) values(?) ";
         ps = con.prepareStatement(query);
         ps.setString(1, "Robert");
         ps.executeUpdate();
         System.out.println("Record is inserted successfully......");
      }
      catch (Exception e) {
         e.printStackTrace();
      }
   }
}

This will produce the following output −

Now let us check the records inserted in the table using select statement −

mysql> select * from DemoTable;

This will produce the following output −

+--------+
| Name   |
+--------+
| Robert |
+--------+
