I did a slight modification but it worked. Many many thanks for your help.
update jos_vm_product set product_sku=concat(product_sku, ' 7') where product_id>'106'
I have another thing I am wanting to accomplish it will make a lot more sense to do it using queries than doing through the Virtuemart interface. I have a client that wants to show 50 stone sizes and instead of just putting in all the stones once and using an option to choose one of the four sizes to order, he wants to show 50 stones in a 7mm category, 50 stones in a 8mm category, 50 stones in a 10mm category, 50 stones in a 12mm category. I advised against it but he is insistent. So now since I do not want to enter 150 stones back into the database using the VM admin, I figured there is some way to insert a copy each of the stones back into the database using a query. So basically there will be four of each kind and then I will go back and add 7mm, 8mm, 10mm, and 12mm to the end of the names to show the difference.
Any suggestions on how I would do that?
