Question

I am looking for the command line command that will display the same thing as the gui

Unindexed Foreign Keys 

Answer 1

There is no command line command (that I know of) which does it. But you can roll your own. Basically you need a query which checks the database for these, which is effectively what your GUI tool must be doing. The query would be something like:

SELECT  FK.table_name, FK.constraint_name
FROM    user_constraints FK
WHERE   FK.constraint_type = 'R'
AND     EXISTS
        (   SELECT  FC.position, FC.column_name
            FROM    user_cons_columns FC
            WHERE   FC.constraint_name = FK.constraint_name
            MINUS
            SELECT  IC.column_position AS position, IC.column_name
            FROM    user_ind_columns IC
            WHERE   IC.table_name = FK.table_name
        )

NOTE: This SQL is NOT perfect. There could be situations where it is fooled into thinking there is an index bet there’s not really. Multiple different indexes with columns in the right place could fool it. To do it properly you’ll need to start grouping in inline views or use analytic functions to ensure all the index columns come from the same index. So I left it at this simple version which will work most of the time.

Then you can run this SQL in sqlplus, or you could embed it in a shell script which is easily run from the command line. A crude one would be:

#!/bin/bash -ue

LOGIN="$1"
sqlplus -s << END_SQL
    $LOGIN
    SET PAGESIZE 5000
    SELECT  FK.table_name, FK.constraint_name
    FROM    user_constraints FK
    WHERE   FK.constraint_type = 'R'
    AND     EXISTS
            (   SELECT  FC.position, FC.column_name
                FROM    user_cons_columns FC
                WHERE   FC.constraint_name = FK.constraint_name
                MINUS
                SELECT  IC.column_position AS position, IC.column_name
                FROM    user_ind_columns IC
                WHERE   IC.table_name = FK.table_name
            )
/
END_SQL

Which you can then run like this and get the basic results:

[user@centos5 sql]$ ./fk.sh scott/tiger@orcl

TABLE_NAME                     CONSTRAINT_NAME
