About statement blocks


We recommend using the run_query macro instead of statement blocks. The run_query macro provides a more convenient way to run queries and fetch their results by wrapping statement blocks. You can use this macro to write more concise code that is easier to maintain.

statements are sql queries that hit the database and return results to your Jinja context. Here’s an example of a statement which gets all of the states from a users table.

{%- call statement('states', fetch_result=True) -%}

select distinct state from {{ ref('users') }}

{%- endcall -%}

The signature of the statement block looks like this:

statement(name=None, fetch_result=False, auto_begin=True)


  • name (string): The name for the result set returned by this statement
  • fetch_result (bool): If True, load the results of the statement into the Jinja context
  • auto_begin (bool): If True, open a transaction if one does not exist. If false, do not open a transaction.

Once the statement block has executed, the result set is accessible via the load_result function. The result object includes three keys:

  • response: Structured object containing metadata returned from the database, which varies by adapter. E.g. success code, number of rows_affected, total bytes_processed, etc. Comparable to adapter_response in the Result object.
  • data: Pythonic representation of data returned by query (arrays, tuples, dictionaries).
  • table: Agate table representation of data returned by query.

For the above statement, that could look like:

{%- set states = load_result('states') -%}
{%- set states_data = states['data'] -%}
{%- set states_status = states['response'] -%}

The contents of the returned data field is a matrix. It contains a list rows, with each row being a list of values returned by the database. For the above example, this data structure might look like:

>>> log(states_data)
