[GitHub] [druid] EgorEna opened a new issue #11607: How to use lookups in a WHERE expression?
EgorEna opened a new issue #11607:
URL: https://github.com/apache/druid/issues/11607
Is there a way to use lookups result to filter an output?
For instance I'm using this query:
"SELECT DISTINCT device_id, LOOKUP(device_id, 'devices') as date_created FROM "my_table" WHERE LOOKUP(device_id, 'devices') != 1"
But this query causes runtime error
Is it working with expessions?

How about trying above query.
```sql
SELECT DISTINCT device_id, LOOKUP(device_id, 'devices') as date_created
FROM "my_table"
WHERE LOOKUP(device_id, 'devices') != '1'
```
