Adding an Expression in Expression Builder

The Visualizer Expression Builder helps you add report-level attributes, measures, or filters based on BQL expressions. You can make these available to other reports in the same space using the Make Global option.

Note: Expression Builder includes integrated syntax help, validation, and pretty-printing. You can access it from the same {} menu.

Note: The Expression Editor Basic mode displays attributes and measures from multiple subject areas to build your expressions and you can save expressions in either a Custom Subject Area or the Default Subject Area.

Note: For Visualizer tables you can use BQL expressions to specify conditional formatting.

BQL provides many functions and operators for expressions in Visualizer. See Supported functions and operators in Visualizer expressions.

The Expression Builder supports a visually-oriented Basic mode and a text-oriented Advanced mode. In Basic mode, the Expression Builder provides type-ahead search to make it easy to add columns, operators, and functions. Use Advanced mode when you want to type a new or copy-paste an existing BQL expression.

Note: Some functions are supported only in Advanced mode.

Expressions you create are available in the Visualizer Subject Area and you can use them like any regular measure or attribute.

Caution:

By default report expressions created in Visualizer are only available for the current report; they are not available for use in other reports. You can make an expression available across the space by clicking Make Global. This is also called a "saved expression". The ability to make an expression global requires the Admin - Manage Access - Manage Groups - Modify Saved Expressions privilege.

Saved expressions that have been created in Designer can also be used in Visualizer reports.

Expression filters are display filters and apply against the query result set in memory.
