Re: Use Driver to Create database?

How to create database with JDBC on PostgreSQL RDMS:

For a complete example that works:

//-- Note that this string ends on "postgres".  That is
//   the name of the default database that can always
//   be connected to.
String dbUrl = "jdbc:postgresql://localhost:8988/postgres";
String dbDriver = "org.postgresql.Driver";
String dbUsername = "Db_test_client";
String dbPassword = "Db_test_pwd";
try { //-- Checks that database driver is loaded
     Class.forName(dbDriver);
}  catch (ClassNotFoundException ex) {
     throw new DbWriteException( ex );
}
try {
     //-- Connect to database
     Connection dbConnection =
DriverManager.getConnection(dbUrl,dbUsername,dbPassword);

     //--Make SURE auto commit is on, because you cannot
     //  add a database to a transaction block.  A trans-
     //  action block is a collection of SQL statements
     //  that are only executed when dbConnection.commit()
     //  is called.
     dbConnection.setAutoCommit(true);
     String sql = "CREATE DATABASE testDatabase";
     Statement cs = dbConnection.createStatement();
     cs.execute(sql);
     cs.close();
     dbConnection.close();

//-- If this code still fails your login account probably
//   does not have privileges to create databases
