Can you create a crypto base on only SQL?

"SQL (Structured Query Language) is a standardized programming language that's used to manage relational databases and perform various operations on the data in them. ... SQL became the de facto standard programming language for relational databases after they emerged in the late 1970s and early 1980s."

SQL is not a general purpose programming language. You must have code that opens the database, creates a table, inserts records, queries records, deletes records, modifies records, and closes it.

MySQL is typically used from server-side PHP, Java, Python etc. or client-side JavaScript.

SQLite is typically used from Android's Java/Kotlin/Xamarin.

It is possible to make changes to the SQL database from the db admin panel by manually typing your own SQL commands.

e.g. mysqladmin for MySQL:

https://dev.mysql.com/doc/refman/8.0/en/mysqladmin.html

Any serious web-hosting company installs such a SQL admin panel, accessible from the HTTP server, to access the database in emergency situations. It is usually used for database backups.
