Detailed Description

This file contains basic method for field types.

Note

This file can be imported from both the server and tools like mysqlbinlog, hence its simplicity

Function Documentation

has_signedess_information_type()

bool has_signedess_information_type ( enum_field_types  type )

inline

Test if the field type contains information on being signed/unsigned.

This includes numeric but also YEAR that still contains sign modifiers even if ignored.

Parameters

type	Field type, as returned by field->type()

Returns

true if the type contains info on being signed/unsigned

is_integer_type()

bool is_integer_type ( enum_field_types  type )

inline

Tests if field type is an integer.

Parameters

type	Field type, as returned by field->type()

Returns

true if integer type, false otherwise

is_numeric_type()

bool is_numeric_type ( enum_field_types  type )

inline

Tests if field type is a numeric type.

Parameters

type	Field type, as returned by field->type()

Returns

true if numeric type, false otherwise

is_string_type()

bool is_string_type ( enum_field_types  type )

inline

Tests if field type is a string type.

Parameters

type	Field type, as returned by field->type()

Returns

true if string type, false otherwise

is_temporal_type()

bool is_temporal_type ( enum_field_types  type )

inline

Tests if field type is temporal, i.e.

represents DATE, TIME, DATETIME, TIMESTAMP or YEAR types in SQL.

Parameters

type	Field type, as returned by field->type().

Return values

true	If field type is temporal
false	If field type is not temporal

is_temporal_type_with_date()

bool is_temporal_type_with_date ( enum_field_types  type )

inline

Tests if field type is temporal and has date part, i.e.

represents DATE, DATETIME or TIMESTAMP types in SQL.

Parameters

type	Field type, as returned by field->type().

Return values

true	If field type is temporal type with date part.
false	If field type is not temporal type with date part.

is_temporal_type_with_date_and_time()

bool is_temporal_type_with_date_and_time ( enum_field_types  type )

inline

Tests if field type is temporal and has date and time parts, i.e.

represents DATETIME or TIMESTAMP types in SQL.

Parameters

type	Field type, as returned by field->type().

Return values

true	If field type is temporal type with date and time parts.
false	If field type is not temporal type with date and time parts.

is_temporal_type_with_time()

bool is_temporal_type_with_time ( enum_field_types  type )

inline

Tests if field type is temporal and has time part, i.e.

represents TIME, DATETIME or TIMESTAMP types in SQL.

Parameters

type	Field type, as returned by field->type().

Return values

true	If field type is temporal type with time part.
false	If field type is not temporal type with time part.

is_timestamp_type()

bool is_timestamp_type ( enum_field_types  type )

inline

Recognizer for concrete data type (called real_type for some reason), returning true if it is one of the TIMESTAMP types.
