 #### Remarks
 
 - The `skipDuplicates` option is not supported by SQLite.
+- Note that the order of elements returned by `createManyAndReturn` is not guaranteed.
 - You **cannot** create or connect relations by using nested `create`, `createMany`, `connect`, `connectOrCreate` queries inside a top-level `createManyAndReturn()` query. See here for a [workaround](/orm/prisma-client/queries/relation-queries#using-nested-createmany).
 - When relations are included via `include`, a separate query is generated per relation.
 - `relationLoadStrategy: join` is not supported.
