+The essential function ''connect()'' establishes a connection to a database using the provided parameters.
+Since ADOdb 5.21,0, some database drivers support the use of [[v5:reference:connection:setconnectionparameter|setConnectionParameter()]], which should be called before connect() to pass extra, database-specific parameters to the connect statement.
+The traditional description of the connection parameters is as follows:
+-------------------------------------
 ^ Parameter 1  ^ Parameter 2  ^ Parameter 3  ^ Parameter 4  ^
 |  $hostName   |  $userId     |  $password   |  $database   |
-However the actual values of the parameters for some databases are such that the actual requirements can be confusing. See the [[database:connection_matrix|Connection Matrix]] for assistance.

+If the connection is made, $db becomes a database connection object that can be used until the script ends. If the connection fails, the value is set to false.
+To debug the connection, set the value '' $db->debug = true; '' before calling the '' $db->connect '' statement
