In this section, we are describing how to list all table names of a database using JDBC API.
List Tables name in Database :
DatabaseMetaData is an interface, implemented by driver which helps user to
know the capabilities of DBMS.
Some DatabaseMetaData methods gives you list of information to the ResultSet
Objects.
Method getMetaData() contains metadata about the database and also contains
information about the database's tables. So you can list all tables name by
using method getTables().
Following is the way to list the tables -
DatabaseMetaData md = con.getMetaData();
ResultSet rs = md.getTables(null, null, "%", null);
Example : In this example we are listing all the tables in the students databse.
package jdbc;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
class GetTableName {
public static void main(String[] args) {
System.out.println("Get all tables name in JDBC...");
Connection con = null;
ResultSet rs = null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "students";
String driverName = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "root";
try {
Class.forName(driverName);
// Connecting to the database
con = DriverManager.getConnection(url + dbName, userName, password);
try {
// Getting all tables name
DatabaseMetaData md = con.getMetaData();
rs = md.getTables(null, null, "%", null);
System.out.println("List of tables in database students -");
while (rs.next()) {
System.out.println(rs.getString(3));
}
} catch (SQLException e) {
System.out.println(e);
}
con.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Output :
Get all tables name in JDBC... List of tables in database students - course student
