The following example converts DATE data in the dob column of the employee table to a numeric format.
Note that the best practice is to define date data as a DATE type; do not define date data as a numeric type.
To change the display from date format to integer format, change the statement to:
SELECT name, dob (INTEGER) FROM employee WHERE dob BETWEEN 380307 AND 420825 ORDER BY dob ;
or
SELECT name, CAST (dob AS INTEGER) FROM employee WHERE dob BETWEEN 380307 AND 420825 ORDER BY dob ;
and the display becomes:
Name DOB ---------- ------ Inglis C 380307 Peterson J 420327
