Columns

You can use the getColumns method of the DatabaseMetaData interface to retrieve column information. You can restrict the results by the table name. The code example below retrieves the column names for the AdAudiences table:

String connectionString = "jdbc:twitterads:InitiateOAuth=GETANDREFRESH;";

Connection conn = DriverManager.getConnection(connectionString);
DatabaseMetaData table_meta = conn.getMetaData();
ResultSet rs = table_meta.getColumns(null,null,"AdAudiences", null);
while(rs.next()){
  System.out.println(rs.getString("COLUMN_NAME")); 
}

The getColumns method returns the following columns:
