Summary
The Add Incrementing ID Field tool adds a database-maintained ID field to an existing table or feature class in an ALTIBASE, IBM DB2, 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
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 ALTIBASE
integer (with database sequence and trigger)
DB2
integer as identity
Oracle
number (with database sequence and trigger)
PostgreSQL
serial
SQL Server
integer with identity property
Syntax
AddIncrementingIDField_management (in_table, {field_name})| Parameter | Explanation | Data Type |
in_table | The location and name of the table to which you want to add an ID field. | Table View |
field_name (Optional) | The name to be used for the ID field. If no input is provided, the name defaults to objectid. | String |
