Add Incrementing ID Field (Data Management)

Summary

Adds a database-maintained, incrementing ID field to an existing table or feature class in a Dameng, IBM Db2, Microsoft Azure SQL Database, Microsoft SQL Server, Oracle, or PostgreSQL database. A database-maintained ID field is required for all feature classes or tables you plan to edit through a feature service.

Usage

Caution:

This tool modifies the input data. See Tools that modify or update the input data for more information and strategies to avoid undesired data changes.

• You cannot run this tool on tables or feature classes that are registered with the geodatabase.

• You must be the owner of the table or feature class to add an ID field to it.

• If you do not specify a name for the field, ObjectID is used by default. If a field named ObjectID already exists, the tool will not run until you provide a different name.

• If a database-maintained, incrementing ID field already exists, this tool will not add another one.

• The following field types will be added:

  DBMS	Data type
  Dameng	int32 with identity property
  Db2	integer as identity
  Oracle	number with identity
  PostgreSQL	serial
  SQL Server	integer with identity property
