Good morning list,
I am designing a system that will have a table for security badges, and we want to store the ID badge photo. These are small files, averaging about 500K in size. We have made the decision to store the image as a BLOB in the table itself for a variety of reasons. However, I am having trouble understanding just how to do that.
The table structures:
CREATE TABLE employee
(
employee_id INTEGER NOT NULL,
employee_lastname VARCHAR(35) NOT NULL,
employee_firstname VARCHAR(35) NOT NULL,
employee_mi CHAR(1),
PRIMARY KEY (employee_id)
);
CREATE TABLE security_badge
(
badge_number CHAR(10) NOT NULL,
employee_id INTEGER NOT NULL
REFERENCES employee(employee_id),
badge_photo ????,
PRIMARY KEY (badge_number)
);
What datatype should I use for the badge_photo (bytea?), and what are the commands to insert the picture accessing the server remotely through psql, and to retrieve the photos as well, please?
Thanks,
Nelson
