Question

I download an XML file containing 1048 records, and then I successfully create a table($today) in my DB, and load the XML data into the MySQL table.

I then run a second script which contains this query:

INSERT INTO
        t1
(
    modelNumber,
    salePrice

    )
SELECT modelNumber,salePrice
FROM `'.$today.'`

ON DUPLICATE KEY UPDATE t1.modelNumber=`'.$today.'`.modelNumber,
 t1.salePrice=`'.$today.'`.salePrice
");

It works, but I’m losing 11 records. The total count is 1037, while the $today table has the exact amount of records contained in the XML file (1048).

How can I correct this problem?

Answer 1

Runs some queries on the $today to find your 11 duplicates.

The ON DUPLICATE KEY clause will suppress these 11 records.
