From PHP Code $Lines is defined as a list of accessions e.g. 123,146,165,1546,455,155

plant table has sequential records with the highest idPlant (unique identifier) of say 1000.

My simple SQL Query:

```
SELECT * FROM plant WHERE `plant`.idPlant IN($Lines) order by plant.idPlant;

```

This brings back row data for '123,146,165' etc.

Is there away to be told that '1546' was not found? (and thus the user probably entered a typo, I can not use a 'confirm all numbers are below X' because in the real data the idPlant may not be sequential and the upper bound will increase during use).

Update:

Looking to get an output that will tell me what Numbers were not found.
