Cannot delete MySQL trigger. Appears in information_schema, but no .TRN file
Based on the suggestion I gave in the chat room, here is my answer


CREATE TABLE cash_op LIKE cash_operation;
Goto the datadir in your Windows server
rename cash_op.MYD cash_op.MYX
copy cash_operation.MYD cash_op.MYD
login to mysql and run


REPAIR TABLE cash_op;
ALTER TABLE cash_operation RENAME cash_op_old;
ALTER TABLE cash_op RENAME cash_operation;

Go create the two triggers on the new cash_operation table


You said in the chat room : Awesome, that worked! You can post it as the answer.

I am glad you gave it a try and it worked for you !!!

BTW you can drop the old table with DROP TABLE cash_op_old;
