sql-parser

sql-parser is a C++ library that converts SQL query strings into structured C++ objects for parsing and analysis. Originally built for the Hyrise database engine, it can be integrated into other C++ projects requiring SQL statement parsing.

What sql-parser is

A MIT-licensed C++ SQL parser that tokenizes and builds abstract syntax tree (AST) representations of SQL statements. Provides type-safe statement objects (SelectStatement, etc.) accessible via a result container, with compilation to shared library (.so) and straightforward header-only integration.

Quickstart

Get the sql-parser source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/hyrise/sql-parser.gitcd sql-parser# follow the project's README for install & configuration

Best use cases

Database Engine Integration

Embed SQL parsing in custom database systems or query optimization engines that need low-level control over statement structure without external process dependencies.

SQL Query Analysis Tools

Build static analysis, validation, or linting tools that examine SQL syntax and semantics before execution, useful for security scanning or optimization recommendation systems.

C++ ORM or Query Builder Backends

Power query builders, schema introspection, or migration tools written in C++ that need to parse user-provided or generated SQL for validation or transformation.

Implementation considerations

  • Requires C++ build toolchain (make, compiler) and manual compilation to .so; no pre-built binaries documented. Verify build compatibility with your target architecture and compiler version.
  • API uses pointer-based result access (getStatement, type casting); memory ownership and lifetime must be carefully managed to avoid leaks or dangling pointers in your integration.
  • Test suite included (make test); run tests post-integration to validate correctness against your SQL grammar expectations and catch parser regressions.
  • No package manager distribution evident (no Conan, vcpkg entries mentioned); include as vendored dependency or build from source in your CI/CD pipeline.
  • Header files must be copied or installed to system/include paths; document installation path clearly for team builds and avoid brittle absolute path assumptions.

When to avoid it — and what to weigh

  • Runtime SQL Compilation Needed — If your application requires compiling arbitrary SQL at scale with minimal latency overhead, the parsing cost and C++ compilation/linking cycle may not suit high-throughput query engines.
  • Multi-Dialect Support Required — The parser is tuned for standard SQL; if you need PostgreSQL, MySQL, Oracle, or other dialect-specific extensions out of the box, this library offers limited dialect flexibility.
  • Non-C++ Ecosystem — Projects primarily in Python, Java, Node.js, or Go should use language-native SQL parsers rather than wrapping this C++ library via FFI, which adds complexity and maintenance overhead.
  • High Availability / Production SLA — No versioned releases since inception (latestRelease: none), archived status is false but release cadence is unclear; production deployments require confidence in maintenance commitment.

Security considerations

Parser operates on untrusted SQL input; verify that malformed or adversarial SQL does not trigger buffer overflows, stack exhaustion, or DoS via pathological grammars. No security audit, fuzzing results, or CVE history documented. Recommend security testing in your integration environment before production use.

Alternatives to consider

libpg_query (PostgreSQL)

If PostgreSQL dialect is acceptable, libpg_query leverages PostgreSQL's battle-tested parser with extensive dialect support and stable releases.

sqlparse (Python) or antlr4 (multi-language)

For projects not committed to C++, Python sqlparse or ANTLR4-based grammars offer better ecosystem integration, more active maintenance, and wider dialect coverage.

Presto/Trino parser (Java)

If Java is viable, Presto's SQL parser is production-hardened, regularly released, and used by major query engines; accessible via JDBC or embedding.

sql-parser FAQ

What SQL statements does this parser support?
Data provided does not list supported statement types comprehensively. README mentions SelectStatement explicitly. Review SelectStatement.h and source to confirm scope (INSERT, UPDATE, DELETE, DDL, etc.). Requires review of codebase.
Can I use this in a multithreaded application?
Thread-safety is not documented. C++ libraries are often not thread-safe by default. Test with concurrent parse() calls in your use case or synchronize access. Requires verification.
Are pre-built binaries available?
No pre-built binaries or package manager entries (Conan, vcpkg, apt, brew) are documented. You must download source and run 'make' to compile libsqlparser.so.
What is the performance overhead of parsing?
No benchmarks, latency targets, or comparative performance data are documented. Performance depends on query complexity and hardware. Profile in your specific deployment scenario.
