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 for 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:
DBMS Data 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 or later releases)
PostgreSQL
serial
SQL Server
integer with identity property
