DB2 Validator

DB2 Validator analyzes Db2 SQL text and optional schema definitions to identify syntax errors, type mismatches, and dialect compatibility issues across Db2 versions. It performs offline analysis, meaning no connection to a live database is required. Conceptually, the tool tokenizes input, parses it against Db2 grammar, and applies a rule set that checks identifiers, data types, and object references. The output is a structured report detailing errors, warnings, and suggested fixes.
The tool supports both Db2 LUW and z/OS dialects and can be tuned for a target version to reflect deprecations or feature differences. This enables developers and DBAs to validate code before deployment or migration, reducing back-and-forth fixes during release cycles.
Distinct value comes from version-aware checks, schema-consistency validation against provided definitions, and exportable diagnostics for integration into CI pipelines. Typical use cases include validating a new stored procedure, a migration script, or a complex query against a given Db2 version. Core features include syntax validation, semantic checks against a supplied schema, and a structured severity-based report. Optional capabilities include cross-object consistency checks and actionable migration hints that suggest index or data-type adjustments. The tool emphasizes offline analysis, supports export of JSON reports, and provides guidance without executing SQL.
