Increment order


Increment order

wish helps you Note that the C++ grammar implies that the associativity of the postfix increment is from left to right, and that of the prefix increment is right to left.
The behaviour of b = a / b++; is actually undefined. This is because = is not a sequencing point, so there are simultaneous reads and writes on b.

Order by date and auto increment column (id), but order rows with same value for third column (oid) alphabetically by fo

To fix this issue Following Quassnoi's answer I have edited to show what happens using his advice and added letters to the OID to show the problematic ordering.
code :
SELECT  m.*
FROM    (
        SELECT  date_placed, oid, MAX(id) AS mid
        FROM    mytable
        GROUP BY
                date_placed, oid
        ) md
JOIN    mytable m
ON      (m.date_placed, m.oid) = (md.date_placed, md.oid)
ORDER BY
        m.date_placed DESC, mid DESC, ab DESC
SELECT  *
FROM    mytable
ORDER BY
        date_placed DESC,
        CASE ab WHEN 'A' THEN id - 1 ELSE id END DESC,
        id

may help you . go to magento log file, payment_paypal_express.log
can you check if the same order info was submitted twice?

With these it helps I don't think you can add an incremental number using derived column transformation, you have to use a script component to achieve that.
Simply add a script component, go to Inputs and Outputs tab and add an Output column of type DT_STR. And inside the script editor use a similar script:
code :
int intOrder = 1;
public override void Input0_ProcessInputRow(Input0Buffer Row)
{

if(!Row.OrderNumber_IsNull && !String.IsNullOrEmpty(Row.OrderNumber)){

    Row.outOrderNumber = Row.OrderNumber + "-" + intOrder.ToString();
    intOrder++;

}else{

    Row.outOrderNumber_IsNull = true;

}

}


Order of operations for pre-increment and post-increment in a function argument?

I think the issue was by ths following , Well, there are two things to consider with your example code:
The order of evaluation of function arguments is unspecified, so whether ++a or a++ is evaluated first is implementation-dependent. Modifying the value of a more than once without a sequence point in between the modifications results in undefined behavior. So, the results of your code are undefined.
