Rev slider activation issue

Hi team,

I am trying to put sliders on my home page so I installed this plugin https://www.premiumpress.com/plugin/revolution-slider-plugin/ . But on activation it is showing error as you can see in screenshot.
Exact Error is:
Fatal error: Uncaught Error: Call to undefined function mysql_error() in /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/inc_php/framework/db.class.php:29 Stack trace: #0 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/inc_php/framework/db.class.php(127): UniteDBRev->checkForErrors(‘fetch’) #1 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/inc_php/revslider_operations.class.php(888): UniteDBRev->fetch(‘wp_revslider_cs…’, ‘handle = ‘.tp-c…’) #2 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/revslider_admin.php(237): RevOperations::importCaptionsCssContentArray() #3 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/revslider_admin.php(131): RevSliderAdmin::createTable(‘revslider_slide…’) #4 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/revslider_admin.php(53): RevSliderAdmin::createDBTables() #5 /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revs in /home2/achtadmin/public_html/dealstantra.com/wp-content/plugins/revslider/inc_php/framework/db.class.php on line 29
