postcode | UK Postcode parsing and helper methods | Data Visualization library

I have a MySQL table with area and lat/lon location columns. Every area has many locations, say 20.000. Is there a way to pick just a few, say 100, that look somewhat evenly distributed on the map?

The distribution doesn't have to be perfect, query speed is more important. If that is not possible directly with MySQL a very fast algorithm that somehow picks evenly distributed locations might also work.

Thanks in advance.

Edit: answering some requests in comments. The data doesn't have something that can be used, it's just area and coordinates of locations, example:

I'm working with a classic ASP VBScript page that queries post town details for a UK postcode given as a parameter, and I've been adding some additional code to catch error situations, e.g.:

1. A blank postcode - I'd like to handle this by displaying an alert dialog.
2. A postcode supplied without a space is handled by inserting the missing space.

We're also in the process of upgrading our website to Google Chrome and MS Edge, so we need to use JavaScript where possible for scripting - I'd like to tell the user that the postcode is blank using the alert() function and I was thinking that the best way to do this would be as follows:

response.write("")

When I try this, I get one of two outputs in the input text box on the page where the result is saved:

1. An HTML-formatted error message like: Microsoft VBScript compilation error '800a0400' Expected statement line 14
2. The

I have a react App component for editing Order information (customer name, items, address, etc.)

• The address is shown using a sub-component that takes Order data & event handlers as properties.
• Changes to address data are handled in the host component (App) by useEffects.
• There are also address-related helper functions that can be invoked.
• Other App sub-components also take the Order data to work with other parts of it.

Here is a simplified version...

In one table I have a full address which I have to split into the city and postcode to store in other columns.

Here is sample address:

I would like to filter post codes to show only the current active for today.

Problem is there are are cities with old post codes (Example).

My current query shows the old post codes:

How can I set a minimum order amount only for Delivery/Shipments (but not for local pickup) and depending on specific post codes?

Use Case: A Restaurant delivers in the local village without minimum amount. But the neighbor villages should have an order amount. Pickup is always without any minimum amount.

Based on Minimum order amount except for specific shipping method in WooCommerce answer code, this is my attempt:
