Class java.sql.Timestamp
Object

+----java.sql.Timestamp
- public class Timestamp
- extends Date
This class is a thin wrapper around java.util.Date that allows
JDBC to identify this as a SQL TIMESTAMP value. It adds the ability
to hold the SQL TIMESTAMP nanos value and provides formatting and
parsing operations to support the JDBC escape syntax for timestamp
values.
Note: This type is a composite of a java.util.Date and a
separate nanos value. Only integral seconds are stored in the
java.util.Date component. The fractional seconds - the nanos - are
separate. The getTime method will only return integral seconds. If
a time value that includes the fractional seconds is desired you
must convert nanos to milliseconds (nanos/1000000) and add this to
the getTime value. Also note that the hashcode() method uses the
underlying java.util.Data implementation and therefore does not
include nanos in its computation.
-
java.sql.Timestamp(int, int, int, int, int, int, int)
- Construct a Timestamp Object
-
java.sql.Timestamp(long)
- Construct a Timestamp using a milliseconds time value.
-
after(Timestamp)
- Is this timestamp later than the timestamp argument?
-
before(Timestamp)
- Is this timestamp earlier than the timestamp argument?
-
equals(Timestamp)
- Test Timestamp values for equality
-
getNanos()
- Get the Timestamp's nanos value
-
setNanos(int)
- Set the Timestamp's nanos value
-

Timestamp
public Timestamp(int year,
int month,
int date,
int hour,
int minute,
int second,
int nano)
- Construct a Timestamp Object
- Parameters:
- year - year-1900
- month - 0 to 11
- day - 1 to 31
- hour - 0 to 23
- minute - 0 to 59
- second - 0 to 59
- nano - 0 to 999,999,999
Timestamp
public Timestamp(long time)
- Construct a Timestamp using a milliseconds time value. The
integral seconds are stored in the underlying date value; the
fractional seconds are stored in the nanos value.
- Parameters:
- time - milliseconds since January 1, 1970, 00:00:00 GMT
after
public boolean after(Timestamp ts)
- Is this timestamp later than the timestamp argument?
- Parameters:
- ts - the Timestamp value to compare with
before
public boolean before(Timestamp ts)
- Is this timestamp earlier than the timestamp argument?
- Parameters:
- ts - the Timestamp value to compare with
equals
public boolean equals(Timestamp ts)
- Test Timestamp values for equality
- Parameters:
- ts - the Timestamp value to compare with
getNanos
public int getNanos()
- Get the Timestamp's nanos value
- Returns:
- the Timestamp's fractional seconds component
setNanos
public void setNanos(int n)
- Set the Timestamp's nanos value
- Parameters:
- n - the new fractional seconds component
toString
public java.lang.String toString()
- Format a timestamp in JDBC timestamp escape format
- Returns:
- a String in yyyy-mm-dd hh:mm:ss.fffffffff format
- Overrides:
- toString in class Date
valueOf
public static java.sql.Timestamp valueOf(String s)
- Convert a string in JDBC timestamp escape format to a Timestamp value
- Parameters:
- s - timestamp in format "yyyy-mm-dd hh:mm:ss.fffffffff"
- Returns:
- corresponding Timestamp
