feat: Address MySQL limitations in delete operation

Changes Made:

1. MySQL does not support LIMIT in subqueries within IN clauses:

   • Previous implementation attempted to use a subquery with LIMIT inside an IN clause for deletion operations, which is not supported by MySQL.
   • To resolve this issue, the operation has been split into two steps:
     • First, fetch the IDs of the records to be deleted using a SELECT query.
     • Second, perform the DELETE operation based on these IDs.

2. MySQL does not support DELETE operations where the filtering condition queries the same table:

   • Originally, the DELETE statement included a WHERE clause that referenced the same table being deleted from, which caused compatibility issues.
   • This has been addressed by first selecting the relevant IDs into a temporary list and then performing the DELETE operation using this list of IDs.

Summary:

To ensure compatibility with MySQL, the code now performs deletions in two steps:

1. Query the IDs of the records to be deleted.
2. Use these IDs to execute the DELETE statement.

This change avoids both the limitation of using LIMIT within subqueries in IN clauses and the issue of referencing the same table in the DELETE statement's WHERE clause.

Please review and let me know if there are any further adjustments needed.

Hey @mmdsnb

Thanks for this fix.

I'm concerned about how performant this is.

I'm not sure this works. Shouldn't it be row.id?
