org.apache.derby.impl.sql.execute .CurrentDatetime

CurrentDatetime
public class CurrentDatetime (Code)
	CurrentDatetime provides execution support for ensuring that the current datetime is evaluated only once for a statement. The same value is returned for every CURRENT_DATE, CURRENT_TIME, and CURRENT_TIMESTAMP in the statement. This is expected to be used by an activation and its result set, and so 'forget' must be called whenever you want to reuse the CurrentDatetime object for additional executions of the statement. author: ames

Constructor Summary
public	CurrentDatetime() The constructor is public; note we wait until evaluation to put any values into the fields.

Method Summary
public void	forget() This is called prior to each execution of the statement, to ensure that it starts over with a new current datetime value.
public Date	getCurrentDate()
public Time	getCurrentTime()
public Timestamp	getCurrentTimestamp()
