In MySQL, which does not support any kind of data integrity constraints, you have to ensure that all the data sent to the DB is validated by the scripts (required fields not empty, invalid characters, etc).

In particular, I am interested in knowing the best/common way of making sure that all the fields that are sent to the DB have data on it. If not, then the update/insert should not occur.

Thanks in advance.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
