Global Variables

This screen shows all global variables used in the application

The global variable is an external parameter required for running the application. The application can include global variables in the WHERE clause, field definitions and names, event programming, and so on.

You can define global variables by using square brackets ([variable]). You can pass the parameters to the application through one of the methods: Session, Post, and Get

IMPORTANT: if you need to use Database Identifiers in your tables, we recommend using the double quotation marks( “ ) instead of the brackets( [ ] ) because of the conflict with the of Global Variables syntax{:target=”_blank”} Scriptcase. Using the brackets as database identifiers may lead to problems in the Scriptcase applications.

Global variables Interface.

Example:

Select CustomerID, CustomerName from Customers WHERE CustomerID = '[v_customerid]'

We do not recommend using session variables (global variables) with the same name as the table fields.

In this case, the variable v_customerid is displaying in the global variables configuration.
