QUESTION
 ' Oracle ORA-00942: table or view does not exist   (942)' in UI Process:
 +++3721 suspended,3  error received when clicking on a table name when
 using the query builder in VisualAge.

ANSWER
 Oracle 6 had had an entry in the all_synonyms table
 for accessible_columns.  That entry pointed the synonym
 accessible_columns to the table all_tab_columns.
 Oracle 7 does not include this table which VisualAge needs.
 To get this table, you can either create a synonym in the
 all_synonyms table of accessible_columns and point it to the
 table all_tab_columns and then VisualAge should run okay.

 Or, Oracle 7 provides a script named CATALOG6.SQL.  This script
 creates version 6 views for compatibility.  The script resides
 in the RDBMS70\ADMIN subdirectory.  If you run this script
 (you probably need DBA authority), it will create the
 ACCESSIBLE_COLUMNS synonym that VisualAge uses.  For details on
 this script, see the 'ORACLE7 Server Migration Guide'.
