Check database Batch support
This is an example of how to check if a database supports batch updates. Checking if a database supports batch updates implies that you should:
- Load the JDBC driver, using the
forName(String className)
API method of the Class. In this example we use the MySQL JDBC driver. - Create a Connection to the database. Invoke the
getConnection(String url, String user, String password)
API method of the DriverManager to create the connection. - Get the DatabaseMetaData, with the
getMetaData()
API method of the Connection. It contains metadata about the database to which this Connection object represents a connection. The metadata includes information about the database’s tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, and so on. - To check whether this database supports batch updates or not invoke the
supportsBatchUpdates()
of the DatabaseMetaData.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core; import java.sql.Connection; import java.sql.DatabaseMetaData; import java.sql.DriverManager; import java.sql.SQLException; public class BatchSupport { public static void main(String[] args) { Connection connection = null; try { // Load the MySQL JDBC driver String driverName = "com.mysql.jdbc.Driver"; Class.forName(driverName); // Create a connection to the database String serverName = "localhost"; String schema = "test"; String url = "jdbc:mysql://" + serverName + "/" + schema; String username = "username"; String password = "password"; connection = DriverManager.getConnection(url, username, password); System.out.println("Successfully Connected to the database!"); } catch (ClassNotFoundException e) { System.out.println("Could not find the database driver " + e.getMessage()); } catch (SQLException e) { System.out.println("Could not connect to the database " + e.getMessage()); } try { DatabaseMetaData dmd = connection.getMetaData(); if (dmd.supportsBatchUpdates()) { System.out.println("Batching is supported"); } else { System.out.println("Batching is NOT supported"); } } catch (SQLException e) { System.out.println("Could not get database metadata " + e.getMessage()); } } }
Example Output:
Successfully Connected to the database!
Batching is supported
This was an example of how to check if a database supports batch updates in Java.
