Will it generate dbt tests for my columns?

Yes, the skill produces schema.yml files that include unique, not_null, and relationship tests derived from the source DDL constraints.

How does it handle DB2-specific functions?

It automatically maps DB2 functions like SUBSTR, LOCATE, and CURRENT DATE to their direct Snowflake equivalents using a comprehensive translation reference.

Does it handle complex data type mapping?

Absolutely. It maps DB2 types like CLOB to VARCHAR and XML to Snowflake VARIANT, while enforcing explicit precision and scale using Snowflake's casting syntax.

Does this skill support DB2 stored procedure conversion?

Yes, it refactors DB2 stored procedures and compound statements into modular dbt models or Snowflake Scripting, favoring declarative SQL where possible.

データベース管理

Converts IBM DB2 DDL and stored procedures into production-ready dbt models and schema configurations optimized for Snowflake.

概要

This skill accelerates data warehouse modernization by translating legacy IBM DB2 objects—including views, tables, and complex stored procedures—into modular dbt models compatible with the Snowflake Data Cloud. It handles the heavy lifting of SQL syntax conversion, transforming procedural SQL PL into declarative dbt code, mapping specific data types, and applying Snowflake-optimized functions. By automatically generating comprehensive schema.yml files with built-in tests and documentation, it ensures that migrated code follows modern data engineering best practices while preserving critical business logic and data integrity.
