The XQuery you are trying to use is effectively being run dynaimcally. Unfortunately, you cannot use dynamic XQuery in SQL Server. Each XQuery must be static.

What you could do in your specific situation, is to break up each node predicate into separate columns. Then in the XQuery you can descend to the relevant node by checking each column. For example:

In short

(1) add the constraint on storyboard.

If you are learning. the simplest here would be to make the constraint from the LEFT OF THE SCREEN to the CENTER OF THE RED BAR

(2) in code, add

Yes, you just have to get the person's NFTs given their wallet address.

To do this, make an API call to the Blockchain API on their "Get Address's NFTs" endpoint. You just have to supply the wallet's public key.

Just use the built-in string converter for doubles:

You can use \

tokenization function can be compared to an hashing function which takes as input the media and outputs the token

This is an incorrect assumption.

You can compare an NFT collection (at least per the most widely used standard - ERC-721) to a key-value dictionary, where the key is an integer ID, and the value is a URL. The standard defines that the URL should lead to a JSON containing the token name, description, and image URL.

But there's no hashing function that would calculate the token parameters based on the image.

Each collection (holding several NFTs) is a smart contract deployed on a different address (e.g. 0x12345). Also, each NFT within its collection has a unique ID (e.g. 1).

Combination of the collection address and the token ID can be used as a unique identificator of each NFT (e.g. 0x12345 / 1).

It's technically possible for multiple different NFTs (no matter whether they're in the same or different collections) to lead to very similar images or even the same image. But the combination of collection address and token ID is always unique.

It turns out that the slowness of boto3 occurs when using Python 2 (which is no longer supported), but not Python 3. With Python 3, boto2 and boto3 have approximately equal speed in my test.

If I correctly understood what you want is basic python tx.py and rx.py which communicate in both real and simulation environment. Then answer is yes.

For Simulation: You can run the 2-node-network.groovy from samples folder.

From the C99 translation phases:

The precedence among the syntax rules of translation is specified by the following phases.

1. Physical source file multibyte characters are mapped, in an implementation- defined manner, to the source character set (introducing new-line characters for end-of-line indicators) if necessary. Trigraph sequences are replaced by corresponding single-character internal representations.
2. Each instance of a backslash character (\) immediately followed by a new-line character is deleted, splicing physical source lines to form logical source lines. Only the last backslash on any physical source line shall be eligible for being part of such a splice. A source file that is not empty shall end in a new-line character, which shall not be immediately preceded by a backslash character before any such splicing takes place.
3. The source file is decomposed into preprocessing tokens and sequences of white-space characters (including comments). A source file shall not end in a partial preprocessing token or in a partial comment. Each comment is replaced by one space character. New-line characters are retained. Whether each nonempty sequence of white-space characters other than new-line is retained or replaced by one space character is implementation-defined.
4. [...]
