ArcMap

Add Incrementing ID Field

Summary

Adds a database-maintained 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 on all feature classes or tables you plan to edit through a feature service.

Usage

  • 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 are added:

    DBMSData Type

    Dameng

    int32 with identity property

    Db2

    integer as identity

    Oracle

    number (with database sequence and trigger if created in Oracle 11g; with identity if created in Oracle 12c)

    PostgreSQL

    serial

    Azure SQL Database and SQL Server

    integer with identity property
