Java---hibernate>>can ' t create table './xxx/#sql-b2c_1a.frm ' (errno:xxx) workaround

Common scenario: Delete related tables and regenerate.

1. Inconsistent data engine inconsistency between related tables results in:

Modify the engine settings for the related table and keep it consistent.

2. The reference type of the associated table index field is different (for example, the A Table association field is a int,b table index is char):

Modify the field type of the related table and keep it consistent.

3. The character encoding of the primary key and foreign key is inconsistent:

Modify the respective table encoding format and keep it consistent.

4. The field referenced in the primary table cannot be found or the associated index is not established:

Either delete the index or add a field.
