Support SQL Ecosystem Code Indexing

Problem to Solve

SQL is fundamental to data-driven applications across all industries. Multiple SQL dialects and variants (PostgreSQL, MySQL, T-SQL, Oracle SQL, BigQuery, Snowflake, etc.) are widely used in enterprise systems, data warehouses, and analytics platforms. SQL code is often embedded in applications, stored procedures, and data pipelines. Currently, the Knowledge Graph lacks SQL support, limiting code intelligence features for database engineers, data engineers, and full-stack developers.

Proposed Solution

Implement a SQL parser that extracts code entities (tables, views, functions, procedures, triggers) and their relationships (queries, dependencies, references) so the Knowledge Graph can index and search SQL codebases intelligently.
