I would like to have postgres update the last_modified column with the
current_date on an update of the record.
I am not sure if there is a very simple way of doing this?
Or, do I need to create a function and a trigger to call the row and update
with new data and set the last_modified to current_date?
Here is the table.
CREATE TABLE price.price_table (
PRICE_DATE DATE,
ID VARCHAR(13),
OPENING NUMERIC(18,6),
CLOSING NUMERIC(18,6),
HIGHEST NUMERIC(18,6),
LOWEST NUMERIC(18,6),
VOLUME BIGINT,
LAST_MODIFIED TIMESTAMP(6) WITHOUT TIME ZONE DEFAULT current_date,
CONSTRAINT PK_PRICE PRIMARY KEY (PRICE_DATE,ID));
Any help would be appreciated.
Cheers,
Chris
