# td_wait>: Waits for data arriving at Treasure Data table

**td_wait>** operator runs a query periodically until it returns true. This operator can use more complex query compared to [td_wait_table> operator](/en/tools/workflows/operators/td_wait_table).


```
_export:
  td:
    database: www_access

+wait:
  td_wait>: queries/check_recent_record.sql

+step1:
  td>: queries/use_records.sql
```

Example queries:

select 1 from target_table where TD_TIME_RANGE(time, '${session_time}') limit 1

select count(*) > 1000 from target_table where TD_TIME_RANGE(time, '${last_session_time}')

Examples:



```
