![]() The result of a test on an internal session variable is independent of the current user’s session. This is useful when testing if permissions are configured properly or the output of the variable is dependent on the user. Test As: You can select a different user to test how the variable will display information for that user. Test: The result of the variable for the current user. There are two forms of testing a session variable: If you have edit access rights to the internal session variable and belong to a group with the Schema Manager role, you can test the variable. The user is able to Edit he internal session variable The user is able to Share the internal session variable with other users The user can View the internal session variable, for example, in the Formula Builder The following are the available access rights for an internal session variable: Property Only a Super User (tenant administrator) or a user that belongs to a group assigned the SuperRole can view, edit, and share all session variables, regardless of ownership. Here is an example of an internal session variable that queries the value of the $yearAgo date system variable. The internal query expression result is the value of the internal session variable.Įxample of the Query property for an internal session variable Optional description of internal session variable.Ĭonstruct an internal query expression using the Formula Builder. ![]() PropertyĮnter the name of the internal session variable Here are the properties of an internal session variable. Properties of an internal session variable besides underscores (_), cannot contain special characters, symbols, or spaces.after the first character, can contain zero or more alphanumeric characters in lower, upper, or mixed case.must begin with an alpha character (lower or upper case) or an underscore (_).must be between 1 and 250 characters in length.The Name of an internal session variable: You can assign access rights to an internal session variable. You can reference an internal session variable in specific expression contexts such as a formula expression. Using the Formula Builder, a schema developer or similar user can define an internal query expression. You can use the Schema Manager to create and test an internal session variable. For the duration of the user's session the variable value exist solely in the scope of the user session and is immutable. The value can be a scalar value of type String or an array of values of the type String. The first time the user invokes an internal session variable - usually by means of a calling expression such a formula expression - the Analytics Services creates an instance of the variable for the user, executes the internal query expression, and then assigns the query result as the variable value for the given user's session. A session maintains state information between requests for a particular user of a web application. When a user signs in to the Analytics Service, the Analytics Service - as a web application - creates a session (HttpSession in Apache Tomcat) for the user. In this regard, the adjective “internal” references the physical schemas and business schemas within a given tenant. An internal query expression typically queries a physical schema table or runtime business view. An internal session variable is a tenant object that defines an internal query expression.
