Query optimization option for SQL statement would need to add the LOCKING ROW FOR ACCESS.

We need an enhancement request submitted in Aha to get query optimization options like
Prefixes that go before the "Select" keyword, i.e. to enable "locking row for access"

    Hello @Marcus Boone
    Currently, users are unable to add query optimization prefixes like LOCKING ROW FOR ACCESS before a SELECT statement. This limitation prevents the fine-tuning of queries to improve performance in environments where many users are concurrently reading from the same table. The absence of this option can lead to unnecessary lock contention, slowing down query execution and impacting overall system performance.


    Example:
    SELECT
    customer_name,
    order_date
    FROM
    customer_orders
    FOR READ ONLY WITH LOCKING ROW FOR ACCESS
    WHERE
    customer_id = 123;

    The enhancement would do:

    This prefix tells the database to run the query with a "read-only lock" that does not block other users from performing write operations. The query gets its data, and other users can continue their work without interruption.

    The enhancement would provide a way for users to add this kind of prefix (or select it from a menu of options) before their SELECT statement to optimize its behavior.
