title: Can't DROP TABLE because unknown table (ERROR 1051)
body: <p>I'm trying to drop a table from a schema I inherited. When I <code>SHOW TABLES</code> I get </p>
  
  <pre><code>+----------------------------+
  | Tables_in_schema_a         |
  +----------------------------+
  | table_1                    |
  | table_2                    |
  | table_3                    |
  | table_4                    |
  | table_5                    |
  | table_6                    |
  +----------------------------+
  </code></pre>
  
  <p>But when I execute <code>DROP TABLE table_1</code> I get </p>
  
  <blockquote>
    <p>ERROR 1051 (42S02): Unknown table 'table_1'</p>
  </blockquote>
  
  <p>I'm using the correct schema. What's going on?</p>
  
  <p>P.S. This is MySQL server is 5.1.73.</p>
