Plugin Management

I have disabled all plugins with the following sql command as my site wasnt working with the DB Cache plugin.

SELECT * FROM wp_options WHERE option_name = 'active_plugins';

I have managed to get my install of wordpress working once again thankfully but when I go to reactivate plugins with sql command my plugins arent activated.

umb-navxt/breadcrumb_navxt_admin.php";i:3;s:46:"custom-post-template/custom-post-templates.php";i:4;s:23:"cu

stom-recent-posts.php";i:6;s:27:"wp-pagenavi/wp-pagenavi.php";}

I have tried reactivating plugins in the wordpress admin area and it does say that plugins are activated but the changes arent working.
