What is MySQL 1120: Failed to open table.

Check if the table exists in the database:

SHOW TABLES;

Verify the table's integrity using MySQL's CHECK TABLE command:

CHECK TABLE yourtablename;

If the table is corrupted, attempt to repair it with:

REPAIR TABLE yourtablename;

Verify the MySQL user has proper permissions to access the table:

SHOW GRANTS FOR 'youruser'@'yourhost';

Check the disk space where the MySQL data directory resides to ensure there's enough space:

df -h
