title: INFORMATION_SCHEMA.COLUMNS suddenly empty
body: <p>Yesterday I developed an SQL query using the COLUMN_NAMES field from INFORMATION_SCHEMA.COLUMNS on an SQL Server database.
  The query worked perfectly fine, especially the query of COLUMN_NAMES correctly output the name of my columns.</p>
  <p>However, this morning I tried re-running the exact same query and this time I got as a result an empty table. Narrowing down the problem, it came down to the following query suddenly giving 0 rows:</p>
  <pre><code>SELECT 
      COLUMN_NAME
  FROM 
      INFORMATION_SCHEMA.COLUMNS
  WHERE 
      TABLE_NAME = 'MyTableName'
  ORDER BY 
      ORDINAL_POSITION
  </code></pre>
  <p>I did strictly no changes to the Server itself. Does anyone has some insight on what could have happened ?</p>
