Automatic column-level lineage from SELECT/CREATE VIEW statements

Dataedo will create column-level data lineage for views and SQL queries based on the script. Just leave the "Automatic lineage" option selected during import.

If you disable this feature during import, you will still be able to trigger the automated creation of column-level lineage through the "Parse Script to Lineage" functionality, which is located in the Script tab.

This function also works for manually added views that were created using a script, as well as for SQL Query objects.

Supported dialects

This function is available in the following dialects:

• MySQL (incl. MariaDB)
• PostgreSQL (inc. Redshift)
• PL/SQL (Oracle)
• Transact-SQL (SQL Server/Azure SQL/Azure Synapse)
• Snowflake SQL (Snowflake)

• SELECT and CREATE VIEW statements,
• Aliases,
• Functions and operators,
• UNIONs,
• JOINs,
• Subqueries and nested queries,
• CASEs and other logic-related expressions,
• Not Recursive Common Table Expressions (CTE).
