title: How to understand if a bigint is signed or unsigned in mysql?
body: <p>I have a table whose create statement is:</p>
  
  <pre><code>CREATE TABLE `takas` (
    `TAKAS_NO` bigint(20) NOT NULL,
    `FIYAT` decimal(20,2) NOT NULL,
    `MIKTAR` decimal(20,5) NOT NULL) 
  
  ...
  </code></pre>
  
  <p>is TAKAS_NO a signed bigint or unsigned? I couldn't find the answer in web. </p>
