Report Builder Functions - Level Function

Returns the current level of depth in a recursive hierarchy.

Note

You can create and modify paginated report definition (.rdl) files in Report Builder and in Report Designer in SQL Server Data Tools. Each authoring environment provides different ways to create, open, and save reports and related items.

Syntax


Level(scope)  

Parameters

scope
(String) (Optional). The name of a dataset, group, or data region that contains the report items to which to apply the aggregate function. If scope is not specified, the current scope is used.

Return Type

Returns an Integer. If scope specifies a dataset or data region, or specifies a nonrecursive grouping (that is, a grouping with no Parent element), Level returns 0. If scope is omitted, it returns the level of the current scope.

Remarks

The value returned by the Level function is zero based; that is, the first level in a hierarchy is 0.

The Level function can be used to provide indentation in a recursive hierarchy, such as an employee list.

For more information about recursive hierarchies, see Creating Recursive Hierarchy Groups (Report Builder and SSRS).

Example

The following code example provides the level of row in the Employees group:

=Level("Employees")
