postgres-syntax

This crate provides simple compile-time syntax checking of PostgreSQL queries using the pg_query crate (currently version 5.1 which uses libpg_query 16-5.1.0).

It doesn't know anything about your schema, so it doesn't do type-checking or verify that tables you reference actually exist. It's just checking that the SQL syntax is valid. If you want type and name checking, you might prefer sqlx.

Crate

Example

The crate provides one macro, postgres_syntax::sql, which takes a string literal and passes it through if it's valid SQL syntax, or emits a compiler error if it's not valid SQL.

use postgres_syntax::sql;

let _ = sql!("SELECT name, email_address FROM user WHERE id = $1 BLARG");
error: failed to parse SQL query: syntax error at or near "BLARG"
 --> examples/bad_syntax.rs:4:11
  |
4 |   let _ = sql!("SELECT name, email_address FROM user WHERE id = $1 BLARG");
  |           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
