12           domain   => 'development',

DESCRIPTION

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
38       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
42       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.

CLASS METHODS

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
54           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
58       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
62           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
68       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
72           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.

364           chooses.
365
366           Returns the value of this attribute in the dbh, if one exists, or
367           the value that will be set when the dbh is next created.
368
369           See the DBD::MariaDB documentation to learn more about this
370           attribute.
371
372   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
379           If the resulting string is longer than max_array_characters, a
380           fatal error will occur.
381
382       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
390           If the resulting string is longer than max_interval_characters, a
391           fatal error will occur.
392
393       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
400       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
406           If a LIST of more than one item is passed, a reference to an array
407           containing the values in LIST is returned.
408
409           If a an ARRAYREF is passed, it is returned as-is.
410
411       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
416           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
422       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
427           If a LIST of more than one item is passed, a reference to an array
428           containing the values in LIST is returned.
429
430           If a an ARRAYREF is passed, it is returned as-is.
431
432       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
436               curdate()
437               current_date
438               current_date()
439               now()
440               sysdate()
441               00000-00-00
442
443           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
447       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
452               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
464           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
468       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
473               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
486           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.
