Sort String To SQL
This is a rust crate to convert 'sort expressions' to SQL expressions that can be used in an 'ORDER BY'. E.g., -date,id will be converted to date DESC NULLS LAST, id ASC NULLS LAST.
It can be used to convert a HTTP query parameter to an expression that can be used in an SQL query. (I'm only using this with Postgres myself, so I can't promise you it will work with other databases.)
Install
# Cargo.toml
[dependencies]
sort_str_to_sql = "1.0.0"
Input Format
Comma separated list of field names. Prepend a '-' for descending order or a '+' for ascending order (which is the default, so it's optional). Append a '-' if you want records with null values first (this sets NULLS FIRST).
You can find some examples in the inline #[test].
