You can use stored procedure and linked lists. The stored procedure parameter can be used in a dependent drop-down list and the stored procedure parameter is defined and used like it is done for a SQL SELECT
statement.
Example
Select command:
-
MS SQL Server:
EXEC MyStoredProc @MyParam
-
Oracle:
EXECUTE MyStoredProc :MyParam
Parameters:
-
Name:
MyParam
-
Field:
REQUEST_MYFIELD
