Methods
Selector methods return all resources that share a common property, using the
syntax method:value
.
The "tag" method
The tag:
method is used to select models that match a specified tag.
The "source" method
The source
method is used to select models that select from a specified source. Use in conjunction with the +
operator.
The "path" method
The path
method is used to select models located at or under a specific path.
While the path
prefix is not explicitly required, it may be used to make
selectors unambiguous.
The "package" method
The package
method is used to select models defined within the root project
or an installed dbt package. While the package:
prefix is not explicitly required, it may be used to make
selectors unambiguous.
The "config" method
The config
method is used to select models that match a specified node config.
The "test_type" method
The test_type
method is used to select tests based on their type, singular
or generic
:
The "test_name" method
The test_name
method is used to select tests based on the name of the generic test
that defines it. For more information about how generic tests are defined, read about
tests.
The "state" method
N.B. State-based selection is a powerful, complex feature. Read about known caveats and limitations to state comparison.
The state
method is used to select nodes by comparing them against a previous version of the same project, which is represented by a manifest. The file path of the comparison manifest must be specified via the --state
flag or DBT_ARTIFACT_STATE_PATH
environment variable.
state:new
: There is no node with the same unique_id
in the comparison manifest
state:modified
: All new nodes, plus any changes to existing nodes.
Because state comparison is complex, and everyone's project is different, dbt supports subselectors that include a subset of the full modified
criteria:
state:modified.body
: Changes to node body (e.g. model SQL, seed values)state:modified.configs
: Changes to any node configs, excludingdatabase
/schema
/alias
state:modified.relation
: Changes todatabase
/schema
/alias
(the database representation of this node), irrespective oftarget
values orgenerate_x_name
macrosstate:modified.persisted_descriptions
: Changes to relation- or column-leveldescription
, if and only ifpersist_docs
is enabled at each levelstate:modified.macros
: Changes to upstream macros (whether called directly or indirectly by another macro)
Remember that state:modified
includes all of the criteria above, as well as some extra resource-specific criteria, such as modifying a source's freshness
or quoting
rules or an exposure's maturity
property. (View the source code for the full set of checks used when comparing sources, exposures, and executable nodes.)
The "exposure" method
The exposure
method is used to select parent resources of a specified exposure. Use in conjunction with the +
operator.
The "metric" method
The metric
method is used to select parent resources of a specified metric. Use in conjunction with the +
operator.
$ dbt build --select +metric:weekly_active_users # build all resources upstream of weekly_active_users metric
$ dbt ls --select +metric:* --resource-type source # list all source tables upstream of all metrics
The "result" method
The result
method is related to the state
method described above, and can be used to select resources based on their result status from a prior run. Note that one of the dbt commands [run
, test
, build
, seed
] must have been performed in order to create the result on which a result selector operates. You can use result
selectors in conjunction with the +
operator.
$ dbt run --select result:error # run all models that generated errors on the prior invocation of dbt run
$ dbt test --select result:fail # run all tests that failed on the prior invocation of dbt test
$ dbt build --select 1+result:fail # run all the models associated with failed tests from the prior invocation of dbt build
$ dbt seed --select result:error # run all seeds that generated errors on the prior invocation of dbt seed.
