14 driver => 'mariadb',
15 database => 'dev_db',
16 host => 'localhost',

28 $db = Rose::DB->new; # $db is really a Rose::DB::MariaDB-derived object
30 ...
31
33 Rose::DB blesses objects into a class derived from Rose::DB::MariaDB
34 when the driver is "mariadb". This mapping of driver names to class
35 names is configurable. See the documentation for Rose::DB's new() and
36 driver_class() methods for more information.
37 This class cannot be used directly. You must use Rose::DB and let its
39 new() method return an object blessed into the appropriate class for
40 you, according to its driver_class() mappings.
41 Only the methods that are new or have different behaviors than those in
43 Rose::DB are documented here. See the Rose::DB documentation for the
44 full list of methods.
45
47 coerce_autoincrement_to_serial [BOOL]
48 Get or set a boolean value that indicates whether or not "auto-
49 increment" columns will be considered to have the column type
50 "serial." If true, "integer" columns are coerced to the "serial"
51 column type, and "bigint" columns use the "bigserial" column type.
52 The default value is true.
53 This setting comes into play when Rose::DB::Object::Loader is used
55 to auto-create column metadata based on an existing database
56 schema.
57 max_array_characters [INT]
59 Get or set the maximum length of varchar columns used to emulate
60 the array data type. The default value is 255.
61 MariaDB does not have a native "ARRAY" data type, but this data
63 type can be emulated using a "VARCHAR" column and a specially
64 formatted string. The formatting and parsing of this string is
65 handled by the format_array and parse_array object methods. The
66 maximum length limit is honored by the format_array object method.
67 max_interval_characters [INT]
69 Get or set the maximum length of varchar columns used to emulate
70 the interval data type. The default value is 255.
71 MariaDB does not have a native "interval" data type, but this data
73 type can be emulated using a "VARCHAR" column and a specially
74 formatted string. The formatting and parsing of this string is
75 handled by the format_interval and parse_interval object methods.
76 The maximum length limit is honored by the format_interval object
77 method.

371 Value Parsing and Formatting
373 format_array ARRAYREF | LIST
374 Given a reference to an array or a list of values, return a
375 specially formatted string. Undef is returned if ARRAYREF points
376 to an empty array or if LIST is not passed. The array or list must
377 not contain undefined values.
378 If the resulting string is longer than max_array_characters, a
380 fatal error will occur.
381 format_interval DURATION
383 Given a DateTime::Duration object, return a string formatted
384 according to the rules of PostgreSQL's "INTERVAL" column type. If
385 DURATION is undefined, a DateTime::Duration object, a valid
386 interval keyword (according to validate_interval_keyword), or if it
387 looks like a function call (matches "/^\w+\(.*\)$/") and
388 keyword_function_calls is true, then it is returned unmodified.
389 If the resulting string is longer than max_interval_characters, a
391 fatal error will occur.
392 format_set ARRAYREF | LIST
394 Given a reference to an array or a list of values, return a string
395 formatted according to the rules of MariaDB's "SET" data type.
396 Undef is returned if ARRAYREF points to an empty array or if LIST
397 is not passed. If the array or list contains undefined values, a
398 fatal error will occur.
399 parse_array STRING | LIST | ARRAYREF
401 Parse STRING and return a reference to an array. STRING should be
402 formatted according to the MariaDB array data type emulation format
403 returned by format_array(). Undef is returned if STRING is
404 undefined.
405 If a LIST of more than one item is passed, a reference to an array
407 containing the values in LIST is returned.
408 If a an ARRAYREF is passed, it is returned as-is.
410 parse_interval STRING
412 Parse STRING and return a DateTime::Duration object. STRING should
413 be formatted according to the PostgreSQL native "interval" (years,
414 months, days, hours, minutes, seconds) data type.
415 If STRING is a DateTime::Duration object, a valid interval keyword
417 (according to validate_interval_keyword), or if it looks like a
418 function call (matches "/^\w+\(.*\)$/") and keyword_function_calls
419 is true, then it is returned unmodified. Otherwise, undef is
420 returned if STRING could not be parsed as a valid "interval" value.
421 parse_set STRING | LIST | ARRAYREF
423 Parse STRING and return a reference to an array. STRING should be
424 formatted according to MariaDB's "SET" data type. Undef is
425 returned if STRING is undefined.
426 If a LIST of more than one item is passed, a reference to an array
428 containing the values in LIST is returned.
429 If a an ARRAYREF is passed, it is returned as-is.
431 validate_date_keyword STRING
433 Returns true if STRING is a valid keyword for the MariaDB "date"
434 data type. Valid (case-insensitive) date keywords are:
435 curdate()
437 current_date
438 current_date()
439 now()
440 sysdate()
441 00000-00-00
442 Any string that looks like a function call (matches /^\w+\(.*\)$/)
444 is also considered a valid date keyword if keyword_function_calls
445 is true.
446 validate_datetime_keyword STRING
448 Returns true if STRING is a valid keyword for the MariaDB
449 "datetime" data type, false otherwise. Valid (case-insensitive)
450 datetime keywords are:
451 curdate()
453 current_date
454 current_date()
455 current_time
456 current_time()
457 current_timestamp
458 current_timestamp()
459 curtime()
460 now()
461 sysdate()
462 0000-00-00 00:00:00
463 Any string that looks like a function call (matches /^\w+\(.*\)$/)
465 is also considered a valid datetime keyword if
466 keyword_function_calls is true.
467 validate_timestamp_keyword STRING
469 Returns true if STRING is a valid keyword for the MariaDB
470 "timestamp" data type, false otherwise. Valid (case-insensitive)
471 timestamp keywords are:
472 curdate()
474 current_date
475 current_date()
476 current_time
477 current_time()
478 current_timestamp
479 current_timestamp()
480 curtime()
481 now()
482 sysdate()
483 0000-00-00 00:00:00
484 00000000000000
485 Any string that looks like a function call (matches /^\w+\(.*\)$/)
487 is also considered a valid timestamp keyword if
488 keyword_function_calls is true.
