Member Function Documentation

Field_datetimef* Field_datetimef::clone ( MEM_ROOT *  mem_root ) const

inlinevirtual

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_root

MEM_ROOT to use for memory allocation.

Return values

NULL	If memory allocation failed.

Implements Field.

Definition at line 3043 of file field.h.

Here is the call graph for this function:

Field_datetimef* Field_datetimef::clone ( ) const

inlinevirtual

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

NULL	If memory allocation failed.

Implements Field.

Definition at line 3048 of file field.h.

Here is the call graph for this function:

ulonglong Field_datetimef::date_flags ( const THD *  thd )

protectedvirtual

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

thd

THD

Return values

sql_mode

flags mixed with the field type flags.

Reimplemented from Field_temporal.

Definition at line 6461 of file field.cc.

bool Field_datetimef::get_date_internal ( MYSQL_TIME *  ltime )

protectedvirtual

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

Implements Field_temporal_with_date.

Definition at line 6499 of file field.cc.

Here is the call graph for this function:

type_conversion_status Field_datetimef::store_internal ( const MYSQL_TIME *  ltime, int *  error  )

protectedvirtual

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

IN	ltime MYSQL_TIME value.
OUT	error Error flag vector, set in case of error.

Return values

false	In case of success.
true	In case of error.

Implements Field_temporal.

Definition at line 6507 of file field.cc.

Here is the call graph for this function:

Here is the caller graph for this function:

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

nr	temporal value in packed longlong format.

Return values

false	on success
true	on error

Reimplemented from Field.

Definition at line 6527 of file field.cc.

Here is the caller graph for this function:

void Field_datetimef::store_timestamp_internal ( const struct timeval *  tm )

protectedvirtual

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.

Definition at line 6467 of file field.cc.

Here is the call graph for this function:

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.
