DB2 SQL Validator

This validator analyzes a provided SQL string for IBM Db2 compatibility. It performs purely static analysis, comparing the input against the DB2 grammar and reserved keywords, and returns a validity flag, error list, and optional guidance. It does not execute queries or connect to a database; results reflect syntax correctness only.
Conceptual workflow: lexical tokenization, parsing with a DB2-specific grammar, and error reporting that maps issues to line and column numbers. When a syntax error is detected, the tool captures the nearest keyword, operator, and nesting level to help locate the fault, and suggests a corrective path (e.g., missing comma, unmatched parenthesis, or misplaced semicolon).
Who benefits: developers writing DB2 SQL, DBAs performing pre-deployment checks, testers validating query changes, and educators teaching DB2 syntax. It helps reduce back-and-forth with runtime validations and accelerates QA cycles by surfacing issues early.
Core features and differentiators: dialect-aware validation across LUW and z/OS variants, detailed error objects with line/column, optional formatting of input, and export-ready results. Compared to generic SQL checkers, it emphasizes DB2-specific constructs like character data types, host variables, and IBM extension syntax.
