Hi,
I have an Oracle (9.2.0) table column that is of type Timestamp...

The DBA declared it as:

ColumnName      Type
CREATETMS       Timestamp(6)

My question is: what does this mean?     Timestamp(6)  ?
Give me an example insert value to insert a value to this column??? (should work)
I am having problem updating this Timestamp with new values from my java program....


Thanks.

From the manual:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/sql_elements2a.htm#47861
---
The TIMESTAMP datatype is an extension of the DATE datatype. It stores the year, month, and day of the DATE datatype, plus hour, minute, and second values. This datatype is useful for storing precise time values. Specify the TIMESTAMP datatype as follows:

TIMESTAMP [(fractional_seconds_precision)]

where fractional_seconds_precision optionally specifies the number of digits Oracle stores in the fractional part of the SECOND datetime field. When you create a column of this datatype, the value can be a number in the range 0 to 9. The default is 6. When you specify TIMESTAMP as a literal, the fractional_seconds_precision value can be any number of digits up to 9, as follows:

TIMESTAMP'1997-01-31 09:26:50.124'
---
An example of an insert would be:
insert into my_table (timestamp_column) values (timestamp'1997-01-31 09:26:50.124');

Hope that helps!

TIMESTAMP [(<precision>)]

The TIMESTAMP datatype stores date and time information with fractional
seconds precision. The only difference between the DATE and TIMESTAMP
datatypes is the ability to store fractional seconds up to a precision of nine digits.
The default precision is 6 and can range from 0 to 9.

>insert into my_table (timestamp_column) values (timestamp'1997-01-31 09:26:50.124');

Is this part ok:   (timestamp'1997-01-31 09:26:50.124'); ?

Should it just be:   ('1997-01-31 09:26:50.124');
