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 | +--------+ 1 row in set (0.00 sec)
