OFFSET and SOFFSET clauses

SELECT "water_level","location" FROM "h2o_feet" LIMIT 3 OFFSET 3

Output:

The query returns the fourth, fifth, and sixth points from the h2o_feet measurement. If the query did not include OFFSET 3, it would return the first, second, and third points from that measurement.

SELECT MEAN("water_level") FROM "h2o_feet" WHERE time >= '2019-08-18T00:00:00Z' AND time <= '2019-08-18T00:42:00Z' GROUP BY *,time(12m) ORDER BY time DESC LIMIT 2 OFFSET 2 SLIMIT 1

Output:

In this example:

• The SELECT clause specifies the InfluxQL MEAN() function.
• The [FROM clause] (/influxdb/v2/query-data/influxql/explore-data/select/#from-clause) specifies a single measurement.
• The WHERE clause specifies the time range for the query.
• The GROUP BY clause groups results by all tags (*) and into 12-minute intervals.
• The ORDER BY time DESC clause returns results in descending timestamp order.
• The LIMIT 2 clause limits the number of points returned to two.
• The OFFSET 2 clause excludes the first two averages from the query results.
• The SLIMIT 1 clause limits the number of series returned to one.

Without OFFSET 2, the query would return the first two averages of the query results:

Output:

Paginate series

SELECT "water_level" FROM "h2o_feet" GROUP BY * SLIMIT 1 SOFFSET 1

Output:

The results above are partial, as the data set is quite large. The query returns data for the series associated with the h2o_feet measurement and the location = santa_monica tag. Without SOFFSET 1, the query returns data for the series associated with the h2o_feet measurement and the location = coyote_creek tag.

Paginate series and include all clauses

SELECT MEAN("water_level") FROM "h2o_feet" WHERE time >= '2019-08-18T00:00:00Z' AND time <= '2019-08-18T00:42:00Z' GROUP BY *,time(12m) ORDER BY time DESC LIMIT 2 OFFSET 2 SLIMIT 1 SOFFSET 1

Output:

In this example:

• The SELECT clause specifies an InfluxQL function.
• The FROM clause specifies a single measurement.
• The WHERE clause specifies the time range for the query.
• The GROUP BY clause groups results by all tags (*) and into 12-minute intervals.
• The ORDER BY time DESC clause returns results in descending timestamp order.
• The LIMIT 2 clause limits the number of points returned to two.
• The OFFSET 2 clause excludes the first two averages from the query results.
• The SLIMIT 1 clause limits the number of series returned to one.
• The SOFFSET 1 clause paginates the series returned.

Without SOFFSET 1, the query would return the results for a different series:
