QUESTION
I am using sql with Javascript to make a simple CRUD project, but when i need to update a user from de DB I get an error saying: "could not prepare statement (1 no such column: (new name))", so I ended up using a DELETE and INSERT instead, but the UPDATE statement is better in terms of time, so I'd like to use the UPDATE.

QUESTION
All.
I got SQL query that sorts the given data inside query.xml file.
As I test on SQLD(Oracle), it gives me back the sorted data as expected.
ANSWER
Answered 2021-Jan-26 at 15:36This is because ?
designates a placeholder value, so you always sort by constant.
Oracle distinguishes between constant int (that you pass via ?
) and integer position of the column, that you put when you do select * from ... order by 1
. For the latter 1 is a part of syntax and acts like an identifier. You can check this with below code.
As you see, the first query treats 1 as column position and sorts by the first column, when the second actually sorts by the second column.
