How to determine if sql script is executed parallel or not?

Question

I am wondering if this sql is going to execute in parallel or not? This is going to be a new sql stored procedure, which will call other three procedures. I want every procedure to start when the previous one has completed.

BEGIN

IF (new_times_flag = TRUE) THEN
    CALL PROCEDURE1(dateFor);
ELSE 
    UPDATE kt_zones_timeslots_settings SET date_for = dateFor WHERE date_for = oldDateFor;
END IF;
    
CALL PROCEDURE2(dateFor);
CALL PROCEDURE3(dateFor);

END

I have read how does sql works in procedure, but I can't find answer of this case exactly. Every next procedure is dependent on the previous so that why I want them to work not in parallel. Something more, these procedures are consist of creating temporary tables, updates, deletes, selects and inserts. I was thinking about something like this (transaction), too:

BEGIN
    BEGIN TRY
        BEGIN TRANSACTION
            IF (new_times_flag = TRUE) THEN
                CALL CalcActualZoneUTR(dateFor);
            ELSE 
                UPDATE kt_zones_timeslots_settings SET date_for = dateFor WHERE date_for = oldDateFor;
            END IF;
                
            CALL MakeRealShifts(dateFor);
            CALL InsertSeparateShifts(dateFor);
    END TRY
    BEGIN CATCH
        ROLLBACK;
    END CATCH
END

Answer 1

The calls in the procedure are executed one by one, not in parallel.
