public class LastUpdateTimestampField

extends TimestampField

implements ICurrentValueField

TimestampField that sets a new timestamp value when being inserted & updated. Creation date: (2/4/2003 3:29:39 PM) Not necessary since fields now check their FD for *CURRENT insert & update values. A TimestampField with *CURRENT default value & *CURRENT auto update value will do the same thing.

LastUpdateTimestampField

public LastUpdateTimestampField()

Method Detail

getAutoUpdateValue

public Object getAutoUpdateValue(ExecutingContext executingContext)
                          throws CMException

Get the field's auto update value as a Timestamp.

Specified by:

getAutoUpdateValue in interface ICurrentValueField

Overrides:

getAutoUpdateValue in class TimestampField

CMException

getDefaultValue

public Object getDefaultValue(ExecutingContext executingContext)
                       throws CMException

Get the field's default value as a Timestamp.

Specified by:

getDefaultValue in interface ICurrentValueField

Overrides:

getDefaultValue in class TimestampField

CMException

getSQLValue

public String getSQLValue(boolean pUseOriginalValue)

Returns the Field's name and value in SQL format.

Overrides:

getSQLValue in class TimestampField

Parameters:

pUseOriginalValue -

Returns:

String

isChanged

public boolean isChanged()

Returns whether or not this Field's value has changed.

Overrides:

isChanged in class Field

Returns:

boolean

isCurrentValueField

public boolean isCurrentValueField()

Returns whether or not this field's value is provided by the database and therefore must have special consideration for updates. For instance, a field that always has the CURRENT TIMESTAMP for its value would get this value from the database. When we go to update, this field will be updated every time that the row is updated, however it will not cause an update in and of itself. Creation date: (2/4/2003 4:40:42 PM)

Overrides:

isCurrentValueField in class Field

Returns:

boolean
