elementAtOrNull
fun <E : Any, T : BaseTable<E>> EntitySequence<E, T>.elementAtOrNull(
index: Int
): E?
(source code)Return an element at the given index or null
if the index is out of bounds of this sequence.
Especially, if a dialect is enabled, this function will use the pagination feature to obtain the very record only.
Assuming we are using MySQL and calling this function with an index 10, a SQL containing limit 10, 1
will be
generated. But if there are no dialects enabled, then all records in the sequence will be obtained to ensure the
function just works.
The operation is terminal.
