VALUES (2987621,'105.03', 'Supplier name')
ON DUPLICATE KEY UPDATE IQ_SUPPLIER =

Thank you for any tips

Answer 1

The update syntax seems a bit off. You’re missing the SET keyword, and multiple columns should be separated by , not AND:

ON DUPLICATE KEY UPDATE 
        IQ_SUPPLIER = IF(IQ_PRICE > 105.03, 'Supplier name', IQ_SUPPLIER) 
        AND IQ_PRICE = IF(IQ_PRICE > 105.03,105.03, IQ_PRICE)
        ^^^

Try this instead:

ON DUPLICATE KEY UPDATE 
SET     IQ_SUPPLIER = IF(IQ_PRICE > 105.03, 'Supplier name', IQ_SUPPLIER) 
,       IQ_PRICE = IF(IQ_PRICE > 105.03, 105.03, IQ_PRICE)
