use lightweight deletes

[iuwqyir]

TL;DR

Updated the DELETE query syntax in ClickHouse to use lightweight DELETE FROM instead of ALTER TABLE DELETE.

What changed?

Modified the query string in the deleteBatch function to use DELETE FROM syntax instead of ALTER TABLE DELETE when removing data from ClickHouse tables.

How to test?

1. Execute delete operations on ClickHouse tables
2. Verify that records are successfully deleted
3. Check that the operation completes without any syntax errors

Why make this change?

The ALTER TABLE DELETE syntax is deprecated in newer versions of ClickHouse. Using DELETE FROM is the standard and recommended approach for delete operations, ensuring better compatibility and maintainability.
