Connecting
To connect to Google Data Catalog, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.
Connect to a DSN
To connect using a DSN:
$cnx = odbc_connect("CData GoogleDataCatalog Sys", "", "");
Provide a Driver Connection String
To connect using an ODBC connection string:
$cnx = odbc_connect("DRIVER={CData ODBC Driver for Google Data Catalog};InitiateOAuth=GETANDREFRESH;ProjectId=YourProjectId;", "", "");
