This MySQL error code is mainly related to subqueries. It appears while updating or deleting a table, and while building a subquery for that using the same table.
How we fix it?
Recently, one of our customers approached us with a request to fix an error like the one shown below, which he was getting while updating a table.
So, our Engineers checked in detail and found that he was using a subquery build with the same table which he wanted to update.
So, we deleted the reference of the table to update from subquery and this fixed the error.
Also, we handled a situation where a customer approached us with the same MySQL error code 1093.
He said this error appeared while trying to delete a table using a query as given below:
DELETE FROM table_name where column_name IN (SELECT column_name FROM table_name WHERE column_name > 10);
We changed the query as below because the customer is trying to delete the rows from the same data source which a subquery refers to, and that cannot be deleted.
DELETE FROM table_name where column_name IN ( SELECT * FROM (SELECT column_name FROM table_name WHERE column_name > 10) AS X) ;
Finally, this fixed the error.
