• isMinimumVersion() — Method to check whether the installed database version is supported by the database driver
• loadAssoc() — Method to get the first row of the result set from the database query as an associative array of ['field_name' => 'row_value'].
• loadAssocList() — Method to get an array of the result set rows from the database query where each row is an associative array of ['field_name' => 'row_value']. The array of rows can optionally be keyed by a field name, but defaults to a sequential numeric array.
• loadColumn() — Method to get an array of values from the <var>$offset</var> field in each row of the result set from the database query.
• loadNextObject() — Method to get the next row in the result set from the database query as an object.

• loadObject() — Method to get the first row of the result set from the database query as an object.
• loadObjectList() — Method to get an array of the result set rows from the database query where each row is an object. The array of objects can optionally be keyed by a field name, but defaults to a sequential numeric array.
• loadResult() — Method to get the first field of the first row of the result set from the database query.
• loadRow() — Method to get the first row of the result set from the database query as an array. Columns are indexed numerically so the first column in the result set would be accessible via <var>$row[0]</var>, etc.
• loadRowList() — Method to get an array of the result set rows from the database query where each row is an array. The array of objects can optionally be keyed by a field offset, but defaults to a sequential numeric array.
• lockTable() — Locks a table in the database.
• quote() — Quotes and optionally escapes a string to database requirements for use in database queries.
• quoteName() — Wrap an SQL statement identifier name such as column, table or database names in quotes to prevent injection risks and reserved word conflicts.
