Rate your experience required. Comments required. Before queries are sent to your data source the query is interpolated , meaning the variable is replaced with its current value. During interpolation, the variable value might be escaped in order to conform to the syntax of the query language and where it is used. For example, a variable used in a regex expression in an InfluxDB or Prometheus query will be regex escaped. Read the data source specific documentation topic for details on value escaping during interpolation. For advanced syntax to override data source default formatting, refer to Advanced variable format options. The formatting of the variable interpolation depends on the data source, but there are some situations where you might want to change the default formatting. For example, the default for the MySql data source is to join multiple values as comma-separated with quotes: 'server01','server02'. In some cases, you might want to have a comma-separated string without quotes: server01,server You can make that happen with advanced variable formatting options listed below.
