I have Table1 with columns:
- id, data type int 
- owned\_items, data type JSON
Table1 values:
first row:
id: 1
owned\_items: {"picture": ["pfp1","pfp2"]}

Table2 with columns:
- id, data type int
- pfp\_name, data type JSON
- source, data type VARCHAR
Table2 values:
first row:
id: 1
pfp\_name: ["pfp1"]
source: source1
second row:
id: 2
pfp\_name: ["pfp2"]
source: source2

please select all sources from Table2 from pictures from Table1 column "owned\_items" from JSON with key "picture" from that array.

Yes, I can help you with that query. Here's how you can do it:

Assuming both tables are in the same database and you have permissions to read from them.

```
SELECT DISTINCT Table2.source
FROM Table1
JOIN Table2 ON Table2.id = JSON_ARRAY_ELEMENT(Table1.owned_items, 'picture').id;
```

In this query, `JSON_ARRAY_ELEMENT` function is used to access the first element of the `picture` array. The `DISTINCT` clause is used to remove duplicates.

This query will give you all the unique sources where pictures are present in `owned_items` column of `Table1` in JSON format with the key "picture".

Note: This query assumes that the `pfp_name` column doesn't contain duplicate keys. If they do, the results may not be accurate.

To achieve this, you would need to use SQL JSON functions to extract the data from the JSON columns. Here's an example of how you might do it in PostgreSQL:

```sql
SELECT Table2.source
FROM Table1
JOIN jsonb_array_elements_text(Table1.owned_items->'picture') AS owned_picture(picture)
JOIN Table2 ON owned_picture.picture = ANY(Table2.pfp_name);
```

In this query:

- `jsonb_array_elements_text(Table1.owned_items->'picture')` is a function that expands the JSON array in the `owned_items` column into a set of text values.
- `AS owned_picture(picture)` gives a name to this set of values.
- `ANY(Table2.pfp_name)` is a way to compare the `picture` value to any value in the JSON array in the `pfp_name` column.

This query will return all `source` values from `Table2` where the `pfp_name` is in the `owned_items` array in `Table1`.

Please note that the JSON functions can vary between different SQL databases. The above example is for PostgreSQL. If you're using a different database like MySQL or SQL Server, you'll need to use the equivalent JSON functions for that database.

Also, please ensure that your JSON data is properly formatted and that the data types match in your tables for the query to work correctly.
