Spring JpaRepostory delete vs deleteInBatch

Question

What is the difference between delete(...) and deleteInBatch(...) methods in JpaRepostory in Spring ? The second one \"deletes items in one SQL stateme

Answer 1

deleteInBatch(...) in the log would look like this: DELETE FROM table_name WHERE (((((((? = id) OR (? = id)) OR (? = id)) OR (? = id)) OR (? = id)) OR (? = id)) OR (? = id))

That might leads to a problem if there are a large amount of data to be deleted, which reaches maximum size of the SQL server query: Maximum size for a SQL Server Query? IN clause? Is there a Better Approach
