> Row("a", "10", false, 0),
> Row("a", null, true, 1), // a was updated and then deleted
> Row("b", null, true, 2), // b was just deleted once
> Row("c", null, true, 3), // c was deleted and then updated twice
> Row("c", "20", false, 4),
> Row("c", "200", false, 5),
> Row("e", "100", false, 6) // new key
> ```
It will work , since it already has `whenNotMatched("B.deleted=false").insertExpr(insertMap)`
