How to turn on specific delivery delay per product in DB ?

[Marquys]

Hello,

I have imported product by CSV file and I have set a "Délai de livraison des produits épuisés avec commande autorisée:" to some products. The specific delay has been imported and I see it in the back office. Unfortunatly, this delay is not displayed because the option "Specific delivery time for this product" is not selected (no column in the CSV field...).

How to turn on the option "Specific delivery time for this product" in the database ? I have 300 products concerned, I can't modify each one by one...

Thanks for your help
