Java DatabaseMetaData supportsTransactions() method with example
The supportsTransactions() method of the DatabaseMetaData interface is used to determine whether the underlying database supports transactions.
This method returns a boolean value which is −
True, when the underlying database supports stored procedures.
False, when the underlying database doesn't support stored procedures.
To determine whether the underlying database supports stored procedures−
Make sure your database is up and running.
Register the driver using the registerDriver() method of the DriverManager class. Pass an object of the driver class corresponding to the underlying database.
Get the connection object using the getConnection() method of the DriverManager class. Pass the URL the database and, user name, password of a user in the database, as String variables.
Get the DatabaseMetaData object with respect to the current connection using the getMetaData() method of the Connection interface.
Finally, invoke the supportsTransactions() method of the ResultSetMetaData interface and save the value it returns in a boolean variable say, bool. If this value is true, underlying database supports stored procedures else it doesn't.
Following JDBC program establishes connection with MySQL database, and determines and prints whether it supports transactions.
Example
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DatabaseMetadata_supportsTransactions {
public static void main(String args[]) throws SQLException {
//Registering the Driver
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//Getting the connection
String url = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(url, "root", "password");
System.out.println("Connection established......");
//Retrieving the meta data object
DatabaseMetaData metaData = con.getMetaData();
//Determining whether the underlying database support transactions
boolean bool = metaData.supportsTransactions();
if(bool) {
System.out.println("Underlying database support transactions");
} else {
System.out.println("Underlying database does not support transactions");
}
}
}Output
Connection established...... Underlying database support transactions
