I'm using golang with Postgresql.
It says here that for operations that do not return rows (insert, delete, update) we should use exec()
If a function name includes Query, it is designed to ask a question of the database, and will return a set of rows, even if it’s empty. Statements that don’t return rows should not use Query functions; they should use Exec().
Then it says here:
Go creates prepared statements for you under the covers. A simple db.Query(sql, param1, param2), for example, works by preparing the sql, then executing it with the parameters and finally closing the statement.
If query() uses under the covers prepared statements why should I even bother using prepared statements?
