Classe: MDB_Manager - X-Ref
The database manager is a class that provides a set of database| raiseError($code = MDB_MANAGER_ERROR, $mode = NULL, $options = NULL,$userinfo = NULL, $nativecode = NULL) X-Ref |
| This method is used to communicate an error and invoke error callbacks etc. Basically a wrapper for PEAR::raiseError without the message string. param: mixed $code integer error code, or a PEAR error object (all param: int $mode error mode, see PEAR_Error docs param: mixed $options If error mode is PEAR_ERROR_TRIGGER, this is the param: string $userinfo Extra debug information. Defaults to the last param: mixed $nativecode Native error code, integer or string depending return: object a PEAR error object |
| captureDebugOutput($capture) X-Ref |
| set a debug handler param: string $capture name of the function that should be used in |
| debugOutput() X-Ref |
| output debug info return: string content of the debug_output class variable |
| resetWarnings() X-Ref |
| reset the warning array |
| getWarnings() X-Ref |
| get all warnings in reverse order. This means that the last warning is the first element in the array return: array with warnings |
| setOption($option, $value) X-Ref |
| set the option for the db class param: string $option option name param: mixed $value value for the option return: mixed MDB_OK or MDB_Error |
| getOption($option) X-Ref |
| returns the value of an option param: string $option option name return: mixed the option value or error object |
| connect(&$dbinfo, $options = FALSE) X-Ref |
| Create a new MDB connection object and connect to the specified database param: mixed $dbinfo 'data source name', see the MDB::parseDSN param: mixed $options An associative array of option names and return: mixed MDB_OK on success, or a MDB error object |
| disconnect() X-Ref |
| Log out and disconnect from the database. |
| setDatabase($name) X-Ref |
| Select a different database param: string $name name of the database that should be selected return: string name of the database previously connected to |
| _createTable($table_name, $table, $overwrite = FALSE) X-Ref |
| create a table and inititialize the table if data is available param: string $table_name name of the table to be created param: array $table multi dimensional array that containts the param: boolean $overwrite determine if the table/index should be return: mixed MDB_OK on success, or a MDB error object |
| _dropTable($table_name) X-Ref |
| drop a table param: string $table_name name of the table to be dropped return: mixed MDB_OK on success, or a MDB error object |
| _createSequence($sequence_name, $sequence, $created_on_table, $overwrite = FALSE) X-Ref |
| create a sequence param: string $sequence_name name of the sequence to be created param: array $sequence multi dimensional array that containts the param: string $created_on_table param: boolean $overwrite determine if the sequence should be overwritten return: mixed MDB_OK on success, or a MDB error object |
| _dropSequence($sequence_name) X-Ref |
| drop a table param: string $sequence_name name of the sequence to be dropped return: mixed MDB_OK on success, or a MDB error object |
| _createDatabase() X-Ref |
| Create a database space within which may be created database objects like tables, indexes and sequences. The implementation of this function is highly DBMS specific and may require special permissions to run successfully. Consult the documentation or the DBMS drivers that you use to be aware of eventual configuration requirements. return: mixed MDB_OK on success, or a MDB error object |
| _addDefinitionChange(&$changes, $definition, $item, $change) X-Ref |
| add change to an array of multiple changes param: array &$changes param: string $definition param: string $item param: array $change return: mixed MDB_OK on success, or a MDB error object |
| _compareDefinitions($previous_definition) X-Ref |
| compare a previous definition with the currenlty parsed definition param: array multi dimensional array that contains the previous definition return: mixed array of changes on success, or a MDB error object |
| _alterDatabase($previous_definition, $changes) X-Ref |
| Execute the necessary actions to implement the requested changes in a database structure. param: array $previous_definition an associative array that contains param: array $changes an associative array that contains the definition of return: mixed MDB_OK on success, or a MDB error object |
| _escapeSpecialCharacters($string) X-Ref |
| add escapecharacters to all special characters in a string param: string $string string that should be escaped return: string escaped string |
| _dumpSequence($sequence_name, $eol, $dump = MDB_MANAGER_DUMP_ALL) X-Ref |
| dump the structure of a sequence param: string $sequence_name param: string $eol return: mixed string with xml seqeunce definition on success, or a MDB error object |
| parseDatabaseDefinitionFile($input_file, $variables, $fail_on_invalid_names = 1) X-Ref |
| Parse a database definition file by creating a Metabase schema format parser object and passing the file contents as parser input data stream. param: string $input_file the path of the database schema file. param: array $variables an associative array that the defines the text param: bool $fail_on_invalid_names (optional) make function fail on invalid return: mixed MDB_OK on success, or a MDB error object |
| _debugDatabaseChanges($changes) X-Ref |
| Dump the changes between two database definitions. param: array $changes an associative array that specifies the list return: mixed MDB_OK on success, or a MDB error object |
| _dumpDatabaseContents($schema_file, $setup_arguments, $dump_arguments, $variables) X-Ref |
| Parse a database schema definition file and dump the respective structure and contents. param: string $schema_file path of the database schema file. param: mixed $setup_arguments an associative array that takes pairs of tag names and values param: array $dump_arguments an associative array that takes pairs of tag names and values param: array $variables an associative array that the defines the text string values return: mixed MDB_OK on success, or a MDB error object |
| getDefinitionFromDatabase() X-Ref |
| Attempt to reverse engineer a schema structure from an existing MDB This method can be used if no xml schema file exists yet. The resulting xml schema file may need some manual adjustments. return: mixed MDB_OK or array with all ambiguities on success, or a MDB error object |
| dumpDatabase($arguments, $dump = MDB_MANAGER_DUMP_ALL) X-Ref |
| Dump a previously parsed database structure in the Metabase schema XML based format suitable for the Metabase parser. This function may optionally dump the database definition with initialization commands that specify the data that is currently present in the tables. param: array $arguments an associative array that takes pairs of tag param: integer $dump constant that determines what data to dump return: mixed MDB_OK on success, or a MDB error object |
| updateDatabase($current_schema_file, $previous_schema_file = FALSE, $variables = array() X-Ref |
| Compare the correspondent files of two versions of a database schema definition: the previously installed and the one that defines the schema that is meant to update the database. If the specified previous definition file does not exist, this function will create the database from the definition specified in the current schema file. If both files exist, the function assumes that the database was previously installed based on the previous schema file and will update it by just applying the changes. If this function succeeds, the contents of the current schema file are copied to replace the previous schema file contents. Any subsequent schema changes should only be done on the file specified by the $current_schema_file to let this function make a consistent evaluation of the exact changes that need to be applied. param: string $current_schema_file name of the updated database schema param: string $previous_schema_file name the previously installed database param: array $variables an associative array that is passed to the argument return: mixed MDB_OK on success, or a MDB error object |
