pg_fake_sqlparser_derive

Procedural macros for the pg_fake_sqlparser fork maintained for pg_fake. This package derives from Apache DataFusion sqlparser-rs and is not an official Apache release. Its Rust library name remains sqlparser_derive.

It provides Visit and VisitMut derives for AST traversal and derive_dialect! for custom SQL dialects.

Recommended use

Enable the corresponding features on the parser crate. It selects the paired derive version automatically:

[dependencies]
sqlparser = { package = "pg_fake_sqlparser", version = "0.63.0", features = ["visitor", "derive-dialect"] }

use sqlparser::derive_dialect;
use sqlparser::dialect::{Dialect, GenericDialect};

derive_dialect!(CustomDialect, GenericDialect, overrides = {
    supports_order_by_all = true,
});

fn main() {
    assert!(CustomDialect::new().supports_order_by_all());
}

Direct dependency and version pairing

If you need a direct dependency on the procedural macros, use both aliases:

[dependencies]
sqlparser = { package = "pg_fake_sqlparser", version = "=0.63.0", features = ["visitor"] }
sqlparser_derive = { package = "pg_fake_sqlparser_derive", version = "=0.6.0" }

Keep the sqlparser dependency key because generated code refers to that name. Derive version 0.6.0 is paired with parser version 0.63.0. Do not substitute the upstream sqlparser or sqlparser_derive packages.

For derive_dialect!, the shipped parser-version file identifies the parser source version. The macro reads src/dialect/mod.rs from the parser repository above derive/, or from the sibling Cargo registry directory pg_fake_sqlparser-0.63.0. It reports an error when that source is missing, instead of selecting another cached parser version. Unversioned vendor layouts are not supported.
