<a href=\"https:\/\/www.gudusoft.com\/jp\/sql-data-lineage-tool\/\">Gudu SQLFlow<\/a> takes this approach with 39 dialect-specific parsers (Snowflake, BigQuery, Oracle, SQL Server, Teradata, and 34 more), built on a SQL compiler front-end developed since the mid-2000s and validated against roughly 13,600 per-dialect test fixtures. That depth is what lets it handle the SQL that breaks simpler parsers: Oracle PL\/SQL and T-SQL stored procedures, dynamic SQL assembled at runtime, temp tables, and view stacks.<\/p>\n\n\n\n<h2
