SELECT statement

Use the SELECT statement to query data from an InfluxDB measurement. The SELECT clause is required when querying data in SQL.


SELECT a, b, "time" FROM <measurement>

Note: When querying InfluxDB, the SELECT statement always requires a FROM clause.

The SELECT clause supports the following:

  • SELECT * - return all tags, fields and timestamps.
  • SELECT DISTINCT to return all distinct (different) values.
  • SELECT <"field" or "tag"> - returns a specified field or tag.
  • SELECT <"field" or "tag">, <"field" or "tag"> - returns more than one tag or field.
  • SELECT <"field"> AS a - return the field as the alias.


The following examples use data from the NOAA database. To download the NOAA test data see NOAA water sample data.

Select a field and perform basic arithmetic

The following query takes the value of water_level, multiplies it by 3 and adds 5 to the result.
