mismatched input 'OWNER' expecting

This error message typically appears in a programming or scripting language when the program encounters a syntax error. "Mismatched input 'OWNER' expecting" means that the program was expecting a particular token or keyword at a specific point in the code, but instead encountered a different token or keyword that it was not expecting.

The specific expectation will depend on the context of the code and the language being used. For example, if the code is related to a database query, the program may be expecting a particular SQL command or keyword, such as "SELECT" or "FROM," but instead encountered the word "OWNER."

To resolve this error, the developer should review the code and ensure that it follows the correct syntax and uses the appropriate keywords or tokens in the correct places. In some cases, the error may be caused by a typo or other mistake, such as a missing semicolon or quotation mark.
