`datetimeColumn ≤ datetime(2018-06-05T20:09:58.907Z)` where the from and to datetimes are from the Grafana time picker.
- `$__timeFrom()` - Returns the From datetime from the Grafana picker. Example: `datetime(2018-06-05T18:09:58.907Z)`.
- `$__timeTo()` - Returns the From datetime from the Grafana picker. Example: `datetime(2018-06-05T20:09:58.907Z)`.
- `$__escapeMulti($myVar)` - is to be used with multi-value template variables that contain illegal characters. If `$myVar` has the following two values as a string `'\\grafana-vm\Network(eth0)\Total','\\hello!'`, then it expands to: `@'\\grafana-vm\Network(eth0)\Total', @'\\hello!'`. If using single value variables there is no need for this macro, simply escape the variable inline instead - `@'\$myVar'`.
- `$__contains(colName, $myVar)` - is to be used with multi-value template variables. If `$myVar` has the value `'value1','value2'`, it expands to: `colName in ('value1','value2')`.

There are also some Grafana variables that can be used in Azure Log Analytics queries:
- `$__from` - Returns the From datetime from the Grafana picker. Example: `datetime(2018-06-05T18:09:58.907Z)`.
- `$__to` - Returns the From datetime from the Grafana picker. Example: `datetime(2018-06-05T20:09:58.907Z)`.
- `$__interval` - Grafana calculates the minimum time grain that can be used to group by time in queries. More details on how it works [here]({{< relref "reference/templating.md#interval-variables" >}}). It returns a time grain like `5m` or `1h` that can be used in the bin function. E.g. `summarize count() by bin(TimeGenerated, $__interval)`
