Member Function Documentation

void Mock_field_timestamp::store_timestamp ( const timeval *  tm )

inlinevirtual

Stores a timestamp value in timeval format in a field.

Note

• store_timestamp(), get_timestamp() and store_time() do not depend on timezone and always work "in UTC".

• The default implementation of this interface expects that storing the value will not fail. For most Field descendent classes, this is not the case. However, this interface is only used when the function CURRENT_TIMESTAMP is used as a column default expression, and currently we only allow TIMESTAMP and DATETIME columns to be declared with this as the column default. Hence it is enough that the classes implementing columns with these types either override this interface, or that store_time(MYSQL_TIME*, uint8) does not fail.

• The column types above interpret decimals() to mean the scale of the fractional seconds.

• We also have the limitation that the scale of a column must be the same as the scale of the CURRENT_TIMESTAMP. I.e. we only allow

[ TIMESTAMP | DATETIME ] (n) [ DEFAULT | ON UPDATE ] CURRENT_TIMESTAMP (n)

Since this interface relies on the caller to truncate the value according to this Field's scale, it will work with all constructs that we currently allow.

Reimplemented from Field.
