Hi guys,

I have a serial owner table which has 1 lakh records and i have serial trans table it has more number of records  says 3 lakhs , I have to update counterpartner field in serial owner from serial trans and I have to select the last recid in the child table.

in short, I have to use updaterecordset  and order by recid .


ttsBegin;

while select forUpdate DMSSerialNumOwner
{
select firstOnly * from DMSSerialNumTrans order by recid desc

where DMSSerialNumTrans.SerialNum == DMSSerialNumOwner.SerialNum; //11052016SAM0011
{
     info(strFmt("%1",DMSSerialNumTrans.RecId));
}

DMSSerialNumOwner.counterpartner = DMSSerialNumTrans.counterpartner ;

DMSSerialNumOwner.update;


}

I want to convert the above code in update record set as it has more than 1 lakhs record.

ttscommit;

    For reference, my reply is in a duplicate thread on another forum. (As with database design, duplicity leads to the same thing done several times, plus maintenance cost to keep data consistent.)

    Hi Rohit,

    You could create a view for DMSSerialNumOwner table with one computed column for counterpartner.

    Instead of updating, you can go for view. Because, the records will be inserted in the DMSSerialNumTrans table after your updation date. If feel, your requirement is different you can create a view and you can link the view with DMSSerialNumOwner table in the update_recordset statement.

    Refer into this link for last record in view

    If you feel it is only for one time, you can directly update in the SQL Management Studio by using update SQL query. Instead of going for sub query, i feel join will improve the performance.

    SQL:

    UPDATE DMSSerialNumOwner
SET counterpartner = T.counterpartner
FROM DMSSerialNumOwner O
INNER JOIN
(
SELECT ROW_NUMBER() OVER (PARTITION BY SerialNum ORDER BY RECID DESC) ROWNUMBER, T.SerialNum, T.counterpartner FROM DMSSerialNumTrans T
) T
ON T.SerialNum == O.SerialNum AND T.ROWNUMBER = 1


    Thanks,

    Hari
