database repair issue

My mac (OS Yosemite & running MAMP in order to serve a development version of my wordpress site) crashed, and now as wordpress tries to launch the browser page says one or more databases need to be repaired. I inserted the required code into my wp-config.php file and followed the directions to repair and optimize the databases. Several errors could not be repaired, and the log in the browser window directed me to post the following errors at this site:

wp_ydlz_users: 1 client is using or hasn’t closed the table properly
wp_ydlz_usermeta: 4 clients are using or haven’t closed the table properly
wp_ydlz_posts: Table is marked as crashed
wp_ydlz_comments: 3 clients are using or haven’t closed the table properly
wp_ydlz_options: Table is marked as crashed
wp_ydlz_postmeta: Table is marked as crashed
wp_ydlz_terms: 1 client is using or hasn’t closed the table properly
wp_ydlz_term_taxonomy: 3 clients are using or haven’t closed the table properly
wp_ydlz_term_relationships: 2 clients are using or haven’t closed the table properly

I would be grateful for any assistance.
