Expressions

Expressions are predefined calculations that take inputs matching a data type and return outputs matching a data type.

Expressions in Tulip differ from expressions as a general concept because they utilize specific Tulip data types, such as a user.

Their syntax (the way they are created) resemble functions from Microsoft Excel.

Expressions are used in the following Models:

  • Triggers: An expression can be used within a trigger action when it is executed in the Tulip Player. It is defined by an app builder.
  • Analysis: An expression can be used to define a configurable field on an Analysis. It is executed every time the Analysis refreshes with new data.

Expressions are defined locally - they exist within the Trigger or Analysis where they are defined.

An expression can be in one of two states:

  • Success: The expression will properly calculate data and can be saved in Tulip
  • Failure: The expression will not properly calculate data and cannot be saved until it is fixed or deleted.

An example expression to convert a string to lowercase:

  • LOWER('a string data type')

Expressions available in Tulip.
