Description
Specific words including SELECT, DELETE, and UPDATE are reserved and should not be used for table, feature class and field names. Attempting to use a reserved word as a table name will return an error. Using a reserved word as a field name will return an error indicating that the column name is invalid. Copying and pasting from a data source where the word is not reserved will add an underscore character to the end of any table or column name that is reserved within the file geodatabase.
The following are reserved keywords:
- ADD
- ALTER
- AND
- BETWEEN
- BY
- COLUMN
- CREATE
- DELETE
- DROP
- EXISTS
- FOR
- FROM
- GROUP
- HAVING
- IN
- INSERT
- INTO
- IS
- LIKE
- NOT
- NULL
- OR
- ORDER
- SELECT
- SET

- UPDATE
- VALUES
- WHERE
Some data sources have their own reserved words. For more details see Defining fields in tables.
