Tables in Object File System do not have a primary index by default. Therefore, these tables are not optimal for single-row access and several types of join plans cannot be used.

Specifying PRIMARY INDEX on a table in Object File System is not valid. No error is returned.

For a CREATE TABLE AS, if the source is a file system table having Primary Index, only a warning is returned and the target Object File System table is created with a warning.
