For example, say I’m creating a table which stores promo codes for a shipping site. I want to have the table match a promo code with the code’s validator, e.g.
PROMO1: Order must have 3 items
PROMO2: Order subtotal must be greater than $50
I would like to store the query and/or routine in a column in the table, and be able to use the content to validate, in the sense of
SELECT * FROM Orders
WHERE Promo.ID = 2 AND Promo.Validation = True
Or something to that effect. Any ideas?
I wouldn’t save the query in the database, there are far better possibilities.
You have to decide, which best fits your needs (it’s not clear for me based on your question). You can use
Views
or
Prepared Statements
or
Stored Procedures
