Operation

Class: Operation

Operations define custom SQL operations that don’t fit into the sqlanvil model of publishing a table or writing an assertion.

You can create operations in the following ways. Available config options are defined in OperationConfig, and are shared across all the following ways of creating operations.

Using a SQLX file:

-- definitions/name.sqlx
config {
  type: "operations"
}
DELETE FROM dataset.table WHERE country = 'GB'

Using action configs files:

definitions/actions.yaml

actions:
- operation:
  filename: name.sql

-- definitions/name.sql
DELETE FROM dataset.table WHERE country = 'GB'

Using the Javascript API:

definitions/file.js

operate("name").query("DELETE FROM dataset.table WHERE country = 'GB'")

Note: When using the Javascript API, methods in this class can be accessed by the returned value. This is where query comes from.

columns

▸ columns(columns: ColumnDescriptor[]): this

deprecated Deprecated in favor of OperationConfig.columns.

Sets the column descriptors of columns in this table.

Parameters:

Name	Type
columns	ColumnDescriptor[]

Returns: this

---

Parameters:

Name	Type
database	string

Returns: this

---

dependencies

▸ dependencies(value: Resolvable | Resolvable[]): this

deprecated Deprecated in favor of OperationConfig.dependencies.

Sets dependencies of the table.

Parameters:

Name	Type
value	Resolvable | Resolvable[]

Returns: this

---

description

▸ description(description: string): this

deprecated Deprecated in favor of OperationConfig.description.

Sets the description of this assertion.

Parameters:

Name	Type
description	string

Returns: this

Parameters:

Name	Type	Default
disabled	boolean	true

Returns: this

---

hasOutput

▸ hasOutput(hasOutput: boolean): this

deprecated Deprecated in favor of OperationConfig.hasOutput.

Declares that this action creates a dataset which should be referenceable as a dependency target, for example by using the ref function.

Parameters:

Name	Type
hasOutput	boolean

Returns: this

---

hermetic

▸ hermetic(hermetic: boolean): void

deprecated Deprecated in favor of OperationConfig.hermetic.

If true, this indicates that the action only depends on data from explicitly-declared dependencies. Otherwise if false, it indicates that the action depends on data from a source which has not been declared as a dependency.

Parameters:

Name	Type
hermetic	boolean

Returns: void

---

queries

▸ queries(queries: Contextable‹IActionContext, string | string[]›): this
