Member Function Documentation

Field_datetimef* Field_datetimef::clone ( MEM_ROOT *  mem_root) const [inline, virtual]

Makes a shallow copy of the Field object.

Note:
This member function must be overridden in all concrete subclasses. Several of the Field subclasses are concrete even though they are not leaf classes, so the compiler will not always catch this.
Parameters:
mem_rootMEM_ROOT to use for memory allocation.
Return values:
NULLIf memory allocation failed.

Implements Field.

Field_datetimef* Field_datetimef::clone ( ) const [inline, virtual]

Makes a shallow copy of the Field object.

Note:
This member function must be overridden in all concrete subclasses. Several of the Field subclasses are concrete even though they are not leaf classes, so the compiler will not always catch this.
Return values:
NULLIf memory allocation failed.

Implements Field.

ulonglong Field_datetimef::date_flags ( const THD *  thd) [protected, virtual]

Flags that are passed as "flag" argument to check_date(), number_to_datetime(), str_to_datetime().

Flags depend on the session sql_mode settings, such as MODE_NO_ZERO_DATE, MODE_NO_ZERO_IN_DATE. Also, Field_newdate, Field_datetime, Field_datetimef add TIME_FUZZY_DATE to the session sql_mode settings, to allow relaxed date format, while Field_timestamp, Field_timestampf do not.

Parameters:
thdTHD
Return values:
sql_modeflags mixed with the field type flags.

Reimplemented from Field_temporal.

bool Field_datetimef::get_date_internal ( MYSQL_TIME *  ltime) [protected, virtual]

Low level function to get value into MYSQL_TIME, without checking for being valid.

Implements Field_temporal_with_date.

type_conversion_status Field_datetimef::store_internal ( const MYSQL_TIME *  ltime,
int *  error 
) [protected, virtual]

Low level routine to store a MYSQL_TIME value into a field. The value must be already properly rounded or truncated and checked for being a valid TIME/DATE/DATETIME value.

Parameters:
INltime MYSQL_TIME value.
OUTerror Error flag vector, set in case of error.
Return values:
falseIn case of success.
trueIn case of error.

Implements Field_temporal.

type_conversion_status Field_datetimef::store_packed ( longlong  nr) [virtual]

Store a temporal value in packed longlong format into a field. The packed value is compatible with TIME_to_longlong_time_packed(), TIME_to_longlong_date_packed() or TIME_to_longlong_datetime_packed(). Note, the value must be properly rounded or truncated according according to field->decimals().

Parameters:
nrtemporal value in packed longlong format.
Return values:
falseon success
trueon error

Reimplemented from Field.

void Field_datetimef::store_timestamp_internal ( const struct timeval *  tm) [protected, virtual]

Store "struct timeval" value into field. The value must be properly rounded or truncated according to the number of fractional second digits.

Implements Field_temporal_with_date_and_time.

longlong Field_datetimef::val_date_temporal ( ) [virtual]

Returns DATE/DATETIME value in packed longlong format. This method should not be called for non-temporal types. Temporal field types override the default method.

Reimplemented from Field_temporal_with_date.
