So, I ask: “which strategy/method should I use to programmatically read the keys from each “block” in the JSON file (in this case, “local”, “coord”, “sentido”, “veiculos”, “modalidade”, “regime”, “pistas” e “medicoes”), create the database with the columns in that same order, and then insert the rows with the proper values”? Fernandes Vieira esquina Protásio Alves",Īnd I have created nice database with a one-to-many relation with these lines of Python code: import sqlite3įoreign key (id) references medicoes(timestamp))''')īUT the problem is, when I was preparing to insert the rows with actual data with something like c.execute("insert into medicoes values(?,?,?,?,?,?,?)" % keys), I realized that, since the dict loaded from the JSON file has no special order, it does not map properly to the column order of the database. My json file is like this (containing traffic data from some crossroads in my city). My intention is to decide later which data container and entry point is best, json (data entry via text editor) or SQLite (data entry via spreadsheet-like GUIs like SQLiteStudio).

Added the sqlite3_error_offset() interface, which can sometimes help to localize an SQL error to a specific character in the input SQL text, so that applications can provide better error messages.The original printf() name is retained as an alias for backwards compatibility. Rename the printf() SQL function to format() for better compatibility.Added the auto modifier and the julianday modifier.Enhancements to date and time functions:.Disable the JSON interface using the new -DSQLITE_OMIT_JSON compile-time option. It is no longer necessary to use the -DSQLITE_ENABLE_JSON1 compile-time option to enable JSON support.

The new operators are compatible with MySQL and PostgreSQL. Added the -> and -> operators for easier processing of JSON.SQLite 3.38 also comes with unixepoch() function for returning a Unix timestamp, sqlite3_error_offset(), virtual table improvements, command-line enhancements, and query planner enhancements. The new operators make it easier for users to work on JSON data that works seamlessly with SQLite, MySQL, and PostgreSQL. The latest version added the -> and -> operations, which makes it easier to process JSON data. JSON1 module was initially added to SQLite 3.9 in 2015. In SQLite 3.38, the JSON module is included by default, eliminating the need for compile-time option.
