    Not very efficient, 1=1 will lead to a full table scan and depending on the number of rows it can take a while. "TRUNCATE TABLE employees;" is a lot faster :)

    I remember that when a company/hr talks about being a family and shit, remember it's like telling a prostitute you love them.

    @sudo-rm-rf it should but some databases throw an error by default when executing a delete statement without where clause, as a safety measure I suppose.

    Truncate is also quicker because it doesn’t write to the redo log and can’t be rolled back

    Delete from employees...

    Foreign key ref errors break the command -> nothing happens
