Error establishing a database connection

Hello Guys,

One of my websites is showing “Error establishing a database connection”.

When I tried to repair the database using “define ( ‘WP_ALLOW_REPAIR’ , true);
” this code in wp-config file.

It is showing something like this:

wp_users: Table ‘gadget41_wp526.wp_users’ doesn’t exist
wp_usermeta: Table ‘gadget41_wp526.wp_usermeta’ doesn’t exist
wp_posts: Table ‘gadget41_wp526.wp_posts’ doesn’t exist
wp_comments: Table ‘gadget41_wp526.wp_comments’ doesn’t exist
wp_links: Table ‘gadget41_wp526.wp_links’ doesn’t exist
wp_options: Table ‘gadget41_wp526.wp_options’ doesn’t exist
wp_postmeta: Table ‘gadget41_wp526.wp_postmeta’ doesn’t exist
wp_terms: Table ‘gadget41_wp526.wp_terms’ doesn’t exist
wp_term_taxonomy: Table ‘gadget41_wp526.wp_term_taxonomy’ doesn’t exist
wp_term_relationships: Table ‘gadget41_wp526.wp_term_relationships’ doesn’t exist
wp_commentmeta: Table ‘gadget41_wp526.wp_commentmeta’ doesn’t exist

Will you anyone please help me
