-942: Unknown table name 

Explanation:

A table with the specified name is not known to you. This table may not exist; or this table exists but you have no privileges for it.

User Action:

Use a QUERY statement issued on the system table DOMAIN.TABLES to find out the names of the tables for which you have privileges. Correct the table name. (It may be sufficient to place the missing owner in front of the name). If correction is not possible, create a table with this name. Check why you have no privileges for the existing table.
