SQL problem multisite installation

Hello,

I get the following error when I want to repair the DB while installing wordpress multisite:

wp_1_posts: Table ‘admin_wp.wp_1_posts’ doesn’t exist
wp_1_comments: Table ‘admin_wp.wp_1_comments’ doesn’t exist
wp_1_links: Table ‘admin_wp.wp_1_links’ doesn’t exist
wp_1_options: Table ‘admin_wp.wp_1_options’ doesn’t exist
wp_1_postmeta: Table ‘admin_wp.wp_1_postmeta’ doesn’t exist
wp_1_terms: Table ‘admin_wp.wp_1_terms’ doesn’t exist
wp_1_term_taxonomy: Table ‘admin_wp.wp_1_term_taxonomy’ doesn’t exist
wp_1_term_relationships: Table ‘admin_wp.wp_1_term_relationships’ doesn’t exist
wp_1_commentmeta: Table ‘admin_wp.wp_1_commentmeta’ doesn’t exist

It gives me this advise:
Some database problems could not be repaired. Please copy-and-paste the following list of errors to the WordPress support forums to get additional assistance.

What can I do? Does anyone have an SQL command that I can enter in PhpMyAdmin? Thank you.
