Question

Here is the problem I am working on:

1. Select all the Oracle database employees whose last names end with “s” Change the
   heading of the column to read Possible Candidates.

I tried

SELECT last_name AS possible_candidates FROM * WHERE last_name LIKE '%s';

That returned the error :

ORA-00903: invalid table name

Unless I am reading the question wrong how do I check the entire database for something like this?

Answer 1

Based on feedback: this appears to be your answer…

Is there a table called employees? if that I would interpret the question as from the employees table. Otherwise, you could select table_name from All_TAB_COLS where column_name like = ‘LAST_NAME’ and then build a union from the resulting tables all of which have a field called ‘LAST_NAME’
