I need an sql query to search "wp_postmeta" table for rows with meta_key "price" and meta_value more than 1 thousand (eg 1.084.51) and delete the first dot of the meta_value.
before: 1.084.51 -> after: 1084.51
I dont know if it is possible to do this with an sql query, anyway I hope it is possible.

Here is a picture:
price

Thanks in advance, Nicolas...

the code is this:
update wp-postmeta
set meta_value = SUBSTR(CONVERT(CONVERT(REPLACE(META_VALUE,'.',''),DECIMAL(16))/100.00,CHAR),1,LENGTH(CONVERT(CONVERT(REPLACE(META_VALUE,'.',''),DECIMAL(16))/100.00,CHAR))-2)
where meta_key = 'price';

Open in new window


It could be improved a lot with regular expressions, but this way uses most basic mysql functions.

Actually accidentally in the first line between wp & postmeta you have add a dash instead of put an underscore.

The code is working 100%, thank you very much Walter Ritzel, appreciate for your time.

This is the code:

update wp_postmeta
set meta_value = SUBSTR(CONVERT(CONVERT(REPLACE(META_VALUE,'.',''),DECIMAL(16))/100.00,CHAR),1,LENGTH(CONVERT(CONVERT(REPLACE(META_VALUE,'.',''),DECIMAL(16))/100.00,CHAR))-2)
where meta_key = 'price';
