The table is currently inaccessible. Possible reasons:
The table was extracted from the database instance using an EXPORT TABLE command.
Another user simultaneously performed a DELETE statement for either a large part of the table or for the whole table. As a result, the specified table was inaccessible for a short period of time. This error message can only occur if you work with Isolation Level 0.
Reload the table into the database using the IMPORT TABLE command.
Wait until the DELETE statement has been executed.
Then execute the SQL statement.
