| In the CREATE TABLE statement, the PHYSICAL clause is used to point to the physical location of the raw data file. This PHYSICAL clause can contain a relative path name (relative to the location of the Omnidex Environment File) such as "dat/states.ost", or an absolute path name such as "d:/class/lab1/dat/states.ost". Unlike fixed-length and delimited files, only one Omnidex Standalone Table can be referenced in the PHYSICAL clause, and wildcards are not allowed. The PHYSICAL clause can reference [[appendix:reference:envvar:home|environment variables]] using a special syntax. | In the CREATE TABLE statement, the PHYSICAL clause is used to point to the physical location of the raw data file.
