Issue/Introduction
When a row is inserted via RC/Edit and then displayed, the timestamp field is populated down to the second as follows:
DB2_TIMESTAMP_DZ
2017-03-04-14.59.00.000000
How to initialize a timestamp column on an INSERT record so that it will store and display the actual microsecond values instead of defaulting to 00.000000?
Resolution
There is a parameter that can be added to the RCEDIT member of the highlevel.CDBAPARM dataset. The parameter is MICROSEC (Y) and can be included in the RC/Edit-Browse Default Values
section of the RCEDIT member. This parameter will specify whether you want microseconds displayed in the default timestamp.
With the value set to Y, the actual microsecond characters will display if the input was the result of an insert of a new data row where a timestamp column is inserted and the default system
timestamp is used to populate the column in the row.
For example: 2017-03-04-14.59.01.123456
This not only decides on the DISPLAY but also what actual data is stored on the table that will be displayed. This parameter will have no impact on existing rows.
Using the EP function on the main menu:
EP Edit Parmlib Members
Select
S RCEDIT - RC/Update
Enter Y or N here:
Actual microseconds for timestamp> Y
Enter to save the change.
In hlq.CDBAPARM(RCEDIT)
you will see:
MICROSEC (Y) /* MICROSECONDS FOR TIMESTAMP (Y OR N) */
/* Y - USE ACTUAL MIRCOSECONDS FOR */
/* DEFAULT TIMESTAMPS */
/* N - REPLACE MICROSECONDS WITH ZEROES */
/* FOR DEFAULT TIMESTAMPS */
