Question

INSERT INTO table VALUES (NULL, 45, 12, NOW(), SELECT MAX(current_price) + 1 FROM table)

I want to insert a row having the “current price” equal to the max price of the the same table plus 1.
I’m using SELECT MAX(current_price) + 1 FROM table to do this.

The problem is the it returns an error.
Can someone help?

Use brackets around sub-query:

INSERT INTO table 
VALUES (NULL, 45, 12, NOW(), (SELECT MAX(current_price) + 1 FROM table));

Better way to do this:

INSERT INTO table 
SELECT NULL, 45, 12, NOW(), MAX(current_price) + 1 FROM table;
