Not 100% sure what you want. If you want to see all the tables that have all three of those columns, then you could do something like:
SELECT table_name, 'CODE', 'MEANING', 'IN_USE'
FROM user_tab_columns
WHERE column_name = 'CODE' and
      table_name like '%CODED%'
INTERSECT
SELECT table_name, 'CODE', 'MEANING', 'IN_USE'
FROM user_tab_columns
WHERE column_name = 'MEANING' and
      table_name like '%CODED%'
INTERSECT
SELECT table_name, 'CODE', 'MEANING', 'IN_USE'
FROM user_tab_columns
WHERE column_name = 'INUSE' and
      table_name like '%CODED%'If you want to select those three columns from each of the tables, then you could do something like this.
Create a command file called, for example, makesel.sql that looks like:
SET PAGES 0 lines 500 trimspool on feedback off;
spool sel.sql;
prompt spool selout.txt;
SELECT 'SELECT '''||table_name||''', code, meaning, in_use FROM '||
       table_name||';'
FROM (SELECT table_name
      FROM user_tab_columns
      WHERE column_name = 'CODE' and
            table_name like '%CODED%'
      INTERSECT
      SELECT table_name
      FROM user_tab_columns
      WHERE column_name = 'MEANING' and
            table_name like '%CODED%'
      INTERSECT
      SELECT table_name
      FROM user_tab_columns
      WHERE column_name = 'INUSE' and
            table_name like '%CODED%')
prompt 'spool off;'
spool off;
@sel.sqlAt the sqlplus prompt run the file using @makesel.sql. This will create another file called sel.sql containing the commands to select those three columns from each table that has all three columns, then after the new file is created, it runs the file (@sel.sql). The output will be spooled to a file called selout.txt.
