Help, I need 3 phpmyadmin sql queries for wordpress database (search & delete etc....)

Help, I need 3 sql queries for phpmyadmin:


I have a wordpress database

1. I need an sql query to search: "wp_terms" & "wp_term_taxonomy" tables
and delete every row that has different term_id except the rows with term_id: 78,32,61,44

Here is 2 pictures from the tables:


2. 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:


3. I need an sql query to search "wp_postmeta" table and delete all rows that has the same post_id that do not include or include partial of the following list of meta_key column:

extraship_Austria, extraship_Belarus, extraship_Belgium, extraship_Brazil, extraship_Canada
extraship_Cyprus, extraship_Czech Republic, extraship_Denmark, extraship_Estonia, extraship_Finland
extraship_France, extraship_Germany, extraship_Greece, extraship_Hungary, extraship_Iceland
extraship_India, extraship_Ireland, extraship_Israel, extraship_Italy, extraship_Latvia
extraship_Luxembourg, extraship_Malta, extraship_Monaco, extraship_Netherlands, extraship_New Zealand
extraship_Norway, extraship_Poland, extraship_Portugal, extraship_Qatar, extraship_Russia
extraship_San Marino, extraship_Spain, extraship_Sweden, extraship_Switzerland, extraship_Turkey
extraship_Ukraine, extraship_United Arab Emirates, extraship_United Kingdom, extraship_United States
extraship_Uruguay, extraship_Vatican City State (Holy See), extraship_Australia

Select allOpen in new window

I want to keep only post_id's that have the full list of meta_key column. It is 42 meta_key records.
Also the post_id record it is included also in wp_posts table in one row only.
I want that row also to be deleted from wp_posts table.
The column header of wp_postmeta table is "post_id" and in wp_posts table is "ID"
I don't know if this is possible but I hope it is.

Here is a big picture edited by me to make you understand the structure:


I know I'm asking a lot and sorry about this. I will try to find what I'm looking for, even with php code but I hope to find a solution here.

Thanks in advance, Nicolas...
