PQN - Polymorphic Qualfiied Name Published by: Bob Cozzi on 10 Sep 2019 view comments

QPN - Polymorphic Qualified Name Syntax

Some SQL iQuery Functions support our polymorphic qualified name (PQN) syntax. This syntax allows users to specify the object name using two separate parameters, one parameter or one qualified parameter. Polymorphic qualified name syntax supports these syntaxes for object names:

  • 'library','object'
  • 'object'
  • 'library/object'

Our Functions typically have 2 parameters for object names:

  1. Library or Schema name
  2. Object or Table name

With PQN syntax, users can omit the 2nd parameter and include the fully qualified object name as the first parameter. For example:




These two variations produce the same results. Two separate parameters, or one parameter with both values.

In addition, if only the object name is specified, for example:


Then the default value for the library or schema is used. Often this is *LIBL, but can be *CURLIB or some other documented value--see the UDTF's documentation for the specific default.
