In my SQL database I have about 5000 content items with the table structure below. Each of these content items has a title, but the metadesc and metakey fields have been left blank. I would like to populate these fields with the unique title. Is there a simple method to copy 'title' to the 'metadesc' and 'metakey' fields for each individual content item?

Here is the table structure for each content item:

--
-- Table structure for table `jos_content`
--
