### Understanding Context Availability
Some Jinja variables like `from_dttm`, `to_dttm`, and `filter` are **only available when a chart or dashboard provides them**. They are populated from:
- Time range filters applied in Explore/Chart views
- Dashboard native filters
- Filter components
**These variables are NOT available in standalone SQL Lab queries** because there's no filter context. If you try to use `{{ from_dttm }}` directly in SQL Lab, you'll get an "undefined parameter" error.
#### Testing Time-Filtered Queries in SQL Lab
To test queries that use time variables in SQL Lab, you have several options:
**Option 1: Use Jinja defaults (recommended)**
```sql
SELECT *
FROM tbl
WHERE dttm_col > '{{ from_dttm | default("2024-01-01", true) }}'
AND dttm_col < '{{ to_dttm | default("2024-12-31", true) }}'
```
**Option 2: Use SQL Lab Parameters**
Set parameters in the SQL Lab UI (Parameters menu):
```json
{
"from_dttm": "2024-01-01",
"to_dttm": "2024-12-31"
}
```
**Option 3: Use `{% set %}` for testing**
```sql
{% set from_dttm = "2024-01-01" %}
{% set to_dttm = "2024-12-31" %}
SELECT *
FROM tbl
WHERE dttm_col > '{{ from_dttm }}' AND dttm_col < '{{ to_dttm }}'
```
:::tip
When you save a SQL Lab query as a virtual dataset and use it in a chart with time filters,
the actual filter values will override any defaults or test values you set.

To add custom functionality to the Jinja context, you need to overload the default Jinja
context in your environment by defining the `JINJA_CONTEXT_ADDONS` in your superset configuration
(`superset_config.py`). Objects referenced in this dictionary are made available for users to use
