dbAddDatabase

Purpose

Adds a database to the list of database connections using the driver type or a connection URL.

Format

db_id = dbAddDatabase(driver_type)

db_id = dbAddDatabase(connection_url)

Parameters:

• driver_type (string) –

  supported options include:

  • DB2

  • IBASE

  • MYSQL

  • OCI

  • ODBC

  • PSQL

  • SQLITE

  • SQLITE2

  • TDS

• connection_url (string) – with the following format: driver://username:password@hostname:port/database_name

Returns:

db_id (scalar) – index into a table of all opened database connections, or 0 on failure.

Examples

db_id = dbAddDatabase("MYSQL");

url = "mysql://webuser:pswd@localhost:3306/dev";
db_id = dbAddDatabase(url);

Remarks

Before using the connection, it must be initialized. e.g., call some or all of dbSetDatabaseName(), dbSetUserName(), dbSetPassword(), dbSetHostName(), dbSetPort(), and dbSetConnectOptions(), and, finally, dbOpen().

The exception to this is using a connection URL, since this performs the above mentioned steps. Omitting portions of the connection URL is allowed, but the syntax must remain the same. For example:

id = dbAddDatabase("oci://root:@localhost:/testing");

is a valid connection URL, but will not set the password or port number fields.
