Sql price update

[zos]

Hello,

 

I recently CSV imported several thousand of products into prestashop (1.6). Several hundred of them got the price wrong. Now thats not a big problem cause I can just run SQL statement equivalent of find&replace on those.

 

The problem: in database I can only find pre-tax prices. I am not at all interested in pre-tax prices. I want to mass update FINAL RETAIL prices.

 

I could theoretically manually subtract 22% (my country's tax) from final retail price and enter those. But thats a lot of extra work and I am worried rounding would get messy. My client won't be happy to see his prices go from 9.90€, 19.90€ etc to some botched 9.87€ or whatever.

 

I did a search on the whole database and a part from the table for layered module there is no mention of the final prices at all.

 

Any help would be greatly appreciated.

 

TLDR; I need to mass change final retail prices, but i can only find pre-tax prices, which are pretty much useless.

Create a spreadsheet and deduct tax. Then copy the whole D column with SQL queries:

    A          B                    C            D
1   tax incl.  tax excl.            id_product   SQL query
2   122.00     =ROUND(A2/1.22; 2)   777          ="UPDATE ps_...... SET price = "&B2&" WHERE id_product = "&C2&";"

@tuk66 I am having the same issue (migrated from 1.5.4 to 1.6.11)

All our prices without taxes are correct and even if the price with taxes will be displayed with "weird" cents, that wouldn't be a problem as some of our products actually have final prices such as 8.17€.

 

My issue is more or less the same that a lot of users are trying to fix: apply the tax rule and update the prices.

 

For the first part my solution would be 

update ps_product set id_tax_rules_group = '4';
update ps_product_shop set id_tax_rules_group = '4';

Now for the second part, updating the final prices by (price without tax) * 1.22 I am really not sure about what SQL I have to run.

 

Can anybody help?
