I am not familiar with the $ syntax for prepared argument placeholders. What database system do they come from?
I have only ever seen ? used for prepared statement placeholders

Here is an example from pgsql's document.
PREPARE fooplan (int, text, bool, numeric) AS
INSERT INTO foo VALUES($1, $2, $3, $4);
EXECUTE fooplan(1, 'Hunter Valley', 't', 200.00);However, only numbers follow the $.
Then I found that there was a need for $foo in the issue. #145 (comment)
So the final product is this:
SELECT * FROM student WHERE id = $Id1;Maybe there can't be a separate $placeholder here.
Thank you even more for your continued contribution. I'm just a spoon of water in the ocean :-)
