Add Incrementing ID Field (Data Management)

Summary

The Add Incrementing ID Field tool adds a database-maintained ID field to an existing table or feature class in an IBM DB2, Microsoft SQL Server, Oracle, or PostgreSQL database. This type of field is required on all feature classes or tables you plan to edit through a feature service.

Usage

• This tool can only be used with database tables, not geodatabase tables.

• You must be the owner of the table 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 in the table, this tool will not add another one.

• The following field types are added to the table:

  DBMS	Data Type
  DB2	integer as identity
  Oracle	number (with database sequence and trigger)
  PostgreSQL	serial
  SQL Server	integer with identity property

Syntax

Parameter	Explanation	Data Type
in_table	The location and name of the table to which you want to add an ID field.	Table View
