It replaces hand-rolled SQL strings with a composable, type-safe interface that automatically escapes values by construction\u2014untrusted input like column values or user-supplied filters are safe to embed without manual quoting. The builder emits actual SQL text (not an AST or opaque object), so queries remain visible in logs, greppable, and cache-keyable.\n\nThe library provides a fa\u00e7ade layer over sqlparser, handling expressions, filters, selections, grouping, and ordering through method chaining. Python scalars auto-promote to literals; specialized operators like JSONB key-exists checks (`has_key`, `has_any_key`, `has_all_keys`) are first-class. An explicit `raw()` escape hatch and `param()` placeholders allow stepping outside the standard grammar when needed. The crate is correctness-critical and tested against DataFusion itself as an oracle to catch silent encoding errors.","worth_installing":"Yes, if you build DataFusion queries from user input or dynamic parameters. The injection-safe-by-construction design and readable SQL output make it worth the medium install friction. Alpha status and 26-day-old release suggest active development; verify dialect coverage for your specific query patterns before production use."},"id":"datafusion-query-builder","links":{"html":"https://skillfed.io/packages/datafusion-query-builder","md":"https://skillfed.io/packages/datafusion-query-builder.md","pypi":"https://pypi.org/project/datafusion-query-builder/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-19","license_spdx":"MIT","license_treatment":"permissive","name":"datafusion-query-builder","python_support":"supports_current","summary":"Programmatic, injection-safe builder for DataFusion SQL."},"popularity":{"monthly_downloads":104416,"position":12749,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
