Limitations

Following schema elements currently are not supported:

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

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_expression_dependencies
  • sys.sql_modules
  • sys.tables
  • sys.views
  • sys.all_objects
  • sys.objects
  • sysobjects
  • sysusers
