title: Can't create databases with names starting with 4E followed by alternate digits and letters.
body: <p>I have this (probably stupid) question about MySQL database names. </p>
  
  <p>Why this statement: "CREATE DATABASE 4E2A_TEST_DB;" throws this error:
  ERROR 1064 (42000): You have an error in your SQL syntax;</p>
  
  <p>While just adding another letter after "4E" (e.g. "CREATE DATABASE 4EX2A_TEST_DB;") works as expected and creates the database?</p>
  
  <p>I tried finding more details in MySQL's documentation but there was nothing specific there...</p>
