Limitations

Following schema elements currently are not supported:

  • Check constraints (vote)
  • Non unique indexes (vote)
  • Unique indexes on views (planned)

Column-level data lineage from SELECT and CREATE VIEW statements

Dataedo based on the script will create for views and SQL queries automatically column-level lineage. Just leave the "Automatic lineage" option checked during import. If you disable the "Automatic lineage" option, you will still have the option to trigger the automatic creation of column-level lineage through the "Parse Script to Lineage" option, which is located in the Script tab.

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

Graphic shows how to run an automatic column-level data lineage in Dataedo

Limitations

We do not support the creation of an automatic lineage for the following SQL syntax:

  • Statements that access nested data such JSON, XML, or objects as columns,
  • PIVOT and UNPIVOT relational operators,
  • Recursive Common Table Expressions (CTE),
  • Dynamic queries,
  • Window functions.

Required access level

Importing database schema requires certain access level in documented database. The user used for importing or updating schema should at least have "View definition" permission granted on all objects that are to be documented. "Select" also works on tables and views.

No data is altered in a source database, therefore no "Select" or "Execute" grant is needed.

Following objects are accessed during schema import process:

  • INFORMATION_SCHEMA.COLUMNS
  • INFORMATION_SCHEMA.KEY_COLUMN_USAGE
  • INFORMATION_SCHEMA.PARAMETERS
  • INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS
  • INFORMATION_SCHEMA.ROUTINES
  • INFORMATION_SCHEMA.TABLES
  • INFORMATION_SCHEMA.VIEWS
  • sys.columns
  • sys.extended_properties
  • sys.indexes
  • sys.index_columns
  • sys.procedures
  • sys.sql_modules
  • sys.tables
  • sys.views
  • sys.all_objects
  • sys.objects
  • sysobjects
  • sysusers
