How to Resolve the MySQL \'Tablespace for table xxx exists\' Error During Import?

Resolving "Tablespace exists" Error during MySQL Import

When encountering the "Tablespace for table xxx exists" error during MySQL data import, it may initially seem counterintuitive that you cannot discard the tablespace due to its non-existence. However, this issue arises from a mismatch between table space information and the actual state of the table.

In some cases, the "tablespace full" error can occur in "innodb_file_per_table" mode. When the innodb_data_file_path tablespace is insufficient, orphans can emerge (.ibd files without .frm counterparts). To rectify this issue:

1. Locate Orphaned .ibd File:

Navigate to the directory where your MySQL files-per-table are stored (e.g., /var/lib/mysql for macOS). Identify any tablename.ibd file that doesn't have an accompanying tablename.frm file.

2. Move Orphaned .ibd File:

Move the orphaned .ibd file to a safe temporary location. This will disconnect it from the database.

3. Execute Queries:

From your MySQL interface, drop the table with the issue (e.g., DROP TABLE temp;) and then create it again (e.g., CREATE TABLE temp (...);).

Note that it's crucial to resolve any underlying issues that may have triggered the error (e.g., long-running queries or locked tables). Failure to do so may result in the reappearance of orphaned .ibd files during subsequent attempts.
