Querying datasets

When you model the data and create datasets, you can analyze the data using the REST API or JDBC Adapter. Metriql provides different reporting features for different use-cases and lets you interact with the data in different ways.

You can use the measure and dimension references of your datasets, filter the data using them and calculate different metrics depending on the report type. See the available report types:

(* is required)
SegmentationFilter, drilldown and calculate the metrics within one datasetevent_timestamp
SQLRun SQL queries with additional Jinja syntax-
FunnelAnalyze customer event data and understand the user journeyuser_id*, event_timestamp*
RetentionAnalyze customer event data and build cohort tablesuser_id*, event_timestamp*

If you're using Metriql in a BI tool, you will most likely be executing Segmentation queries.

Here are the common properties of the available report types:


You can reference datasets using the ref or source functions in your dbt project as follows:

dataset: source('events', 'pageview')

Alternatively, you can override the dataset name using property as follows:

- events
name: events

and reference the events model as follows:

dataset: events # alternative to ref('events')


You can reference the measures by their name. If you're using column.meta.metriql.measure, you need to specify the name of the measure explicity as follows:

- events
aggregation: count
- name: revenue
aggregation: sum
name: total_revenue

For the events dataset here, total_events and total_revenue are the available measures that you can reference in the queries.


Metriql automatically maps all your columns as dimensions. If the column name has non-alphanumeric characters, you should define name of the dimension explicitly to be able to reference as follows:

- name: "test column"
name: test_column

If you're referencing a date, timestamp, time dimension, you can use the timeframes as follows:



You can filter datasets by their dimensions and measures. There are different operators available for different types.

You can reference dimensions in the filter as shown below. You can also reference mappings with : prefix. For example, use :user_id in dimension if you want to filter by user_id.

- dimension: country
operator: equals
value: USA
- or:
- {dimension: city, operator: equals, value: San Francisco}
- {dimension: city, operator: equals, value: New York}

If the value is an array, Metriql will merge the filters with OR otherwise; use AND. For the query above, Metriql will compile it to the following SQL expression:

WHERE country = 'USA' AND (city = 'San Franscisco' OR city = 'New York')

or, you can reference a measure in the filter:

- measure: total_revenue # adds a HAVING condition to the query
operator: equals
value: value_for_operator

The filter object can either have and and or property that is an array or a single filter that has one of measure, dimension, and mapping with operator and value properties.


For different field types, Metriql offers different operators to filter the data.

For all types:#

is_set and is_not_set can be used for NULL checks. The value must not be set.

filters: [{measure: vendor_type, operator: is_set}]

For integer, decimal, double, long:#

not_equals , less_than, equals, greater_than. The value must be a numeric value

filters: [{measure: time_spent_on_page, operator: greater_than, value: 10}]

For boolean:#

is can be used for boolean equity checks. The value can be either true or false

filters: [{dimension: is_upgraded, operator: is, value: true}]

For timestamp:#

equals, less_than, greater_than, between. The value can be defined as absolute or relative values.

Relative values#

You can add timestamp filters relative to the current timestamp as follows:

filters: [{dimension: created_at, operator: between, value: '1 day'}]

The filter above compiles to the following SQL:

created_at >= CAST(DATEADD(DAY, -1, to_date(date_trunc('day', CURRENT_TIMESTAMP)) AS TIMESTAMP))
AND created_at < CAST(DATEADD(DAY, 1, to_date(date_trunc('day', CURRENT_TIMESTAMP)) AS TIMESTAMP))

Metriql filters the data from the beginning of the previous day to the end of the current day for 1 day.

The date period can be either minute, hour, day, week, month, or year. Metriql also supports the plural versions such as minutes.

Absolute values#

If you want to select based on absolute date intervals, the value must be an object as follows:

filters: [{dimension: created_at, operator: between, value: {start: '2020-01-10', end: '2020-01-20'}}]

The filter above compiles to the following SQL:

created_at >= CAST('2020-01-10' AS TIMESTAMP) AND created_at < CAST('2020-01-20' AS TIMESTAMP)

If you set the timezone defined in your config file, all the timestamp references are wrapped with timezone conversion function. For example, in Snowflake it's CONVERT_TIMEZONE('UTC', CAST('2020-01-20' AS TIMESTAMP))

For date:#

equals, less_than, greater_than, between. The value can be defined as absolute or relative values similar to timestamp type.

For time:#

equals, less_than, greater_than. The value should be a string as follows:

filters: [{dimension: occurred_at_time, operator: equals, value: '16:00'}]

If you set the timezone defined in your config file, the time value will be shifted for your timezone.

For array_string:#

includes, not_includes. You can use the filters as follows:

filters: [{dimension: items, operator: includes, value: 'array_item'}]

Metriql actually has types array_* for all primitive types and the value can be set based on the primitive type as follows:

filters: [{dimension: array_integer_dimension, operator: includes, value: 4}]

Referencing fields from other datasets through relations#

If you define a relation between multiple datasets, you can also access the measures and dimensions in the target datasets.

- name: countries
aggregation: count
- name: pageviews
to: ref('countries')
sql: "{TABLE}.country = {TARGET}.iso_code"
type: left_join
relationship: many_to_many

In this case, the reference countries.total_countries from the dataset pageviews automatically creates a join in your SQL query. Learn more about the relations here.
