2 Ways to Return the Julian Day in SQLite
Here are two methods for returning the Julian Day in SQLite.
The Julian Day is the fractional number of days since noon in Greenwich on November 24, 4714 B.C. It’s the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events.
SQLite ->> Operator
In SQLite, the ->> operator extracts a subcomponent from a JSON document and returns an SQL representation of that subcomponent.
The ->> operator was first introduced in SQLite version 3.38.0 (released on 22 February 2022).
SQLite -> Operator
In SQLite, the -> operator extracts a subcomponent from a JSON document and returns a JSON representation of that subcomponent.
The -> operator was first introduced in SQLite version 3.38.0 (released on 22 February 2022).
SQLite JSON_TREE()
In SQLite, json_tree() is a table-valued function that walks the JSON value provided as its first argument and returns a table consisting of one row for each array element or object member.
We provide the JSON value as an argument when we call the function.
SQLite JSON_EACH()
In SQLite, json_each() is a table-valued function that walks the JSON value provided as its first argument and returns a table consisting of one row for each array element or object member.
We provide the JSON value as an argument when we call the function.
SQLite JSON_TYPE()
The SQLite json_type() function returns the type of the outermost element of the given JSON.
We provide the JSON as an argument when we call the function.
We can optionally pass a path, which allows us to get the type of a specific array element or object member within the JSON.
SQLite JSON_QUOTE()
In SQLite, the json_quote() function converts a number or string into its corresponding JSON representation.
We provide the number or string as an argument when we call the function, and the function returns a JSON representation of that value.
