This guide provides information on using HCL Domino Designer and programming language reference information.
Connectors
Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
LSX for Connectors
LotusScript® Extensions for Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.
Chapter 1 Introduction
This chapter provides an introduction to the LotusScript® Extension for Connectors (LC LSX) and explains the organization of this manual.
Connectivity Software Requirements
Access to supported Connectors may require software to be installed on the Domino® server or the Notes® client from which the LC LSX scripts are run.

- Domino® Query Language
  Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.
- Composite Applications - Design and Management
  Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.
- DB2® Access views
  Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:

        This section lists documentation that you may find useful as you learn about and use the various Connectors.
      - Overview of the LotusScript® Extension for Connectors
        The Connectors provide native access to a wide variety of database management system (DBMS) products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems. The LotusScript® Extension for Connectors (LC LSX) extends these connectors to LotusScript.
      - Connectivity Software Requirements
        Access to supported Connectors may require software to be installed on the Domino® server or the Notes® client from which the LC LSX scripts are run.
      - Loading and Registering the LC LSX
        You must load the LotusScript® Extensions for Connectors (LC LSX) using the following statement in your script:
      - Terms and Concepts
        Key terms are defined as follows.
      - LC Classes
        The Connectors provides external data and system access to the LotusScript® environment. The LSX classes consist of LCConnection, LCFieldlist and LCField, and four advanced data types, LCStream, LCNumeric, LCCurrency, and LCDatetime. In addition to these seven classes, there is also an LCSession class. Each of these classes and their primary usage is described as follows.
      - Working with the LC LSX
        A typical use of the Connectors is to gather, create, or modify data in an external system. For example, a Notes® application has a number of data fields on a form. Once the user input is complete, a button activates the script to take the form data and establish a connection to Oracle, locating corresponding information from one or more tables and updating the Notes form. The script is responsible for the following tasks:
      - Connection Pooling
        Connection pooling is part of the common LC API. The Connector LotusScript® Extesnions (LSX) provides an end-user interface to the pooling code. The functionality is switched off by default, this minimizes any potential adverse behavior connection pooling might introduce to existing code.
      - LotusScript® and Notes®
        Use of the Connectors LotusScript® Extensions (LC LSX) is limited to the Notes® environment and Notes applications. The connectors only have context within the Domino® server and Notes client.
      - Security and Access
        Agents or other LotusScript® code that uses the Notes® connector or File connector must be signed with a Notes ID that has permission to run unrestricted agents. This also applies to any script libraries used by such code. Specifically, connections through these connectors will be blocked with an error unless the signing Notes ID has this permission.
      - LC LSX Data Types
        Standard and advanced Connector LotusScript® Extensions (LC LSX) data types are described as follows.
      - Arrays and Indexes
        The default for array indexes in LotusScript® is 0 based. For example, elements of an array are specified as Elem(0), Elem(1), Elem(2), etc. The "Option Base n" LotusScript option lets you make the default lower bound of an unspecified array something other than 0. The Connector LotusScript Extensions (LC LSX) do not support this syntax. It is recommended, for consistency, that within scripts which use an LC LSX, such as the Connectors, this option not be used.
      - Working with Multiple Rows of Data
        The Fetch, Insert, Update, Remove methods of a connection use a RecordCount parameter and may operate on more than a single row at a time. However, the LCFiedllist parameter must have been created to hold more than one record for this to work. You may operate on fewer records than the Fieldlist was created with, but not more.
      - Optional Parameters
        Some methods have optional parameters. The LotusScript® keyword "Nothing" is used for output parameters that the user is not interested in receiving. If one or more optional parameters are at the end of a call, they may simply be ignored as in the case of a datetime. For example, a datetime with only the date portion provided is created using the following statement.
      - Performance
        Certain techniques can be used to increase Connector LotusScript® Extensions (LC LSX) code performance. These techniques will be described.
      - Initialization File Variables
        HCL Enterprise Integrator (HEI) and Domino® Enterprise Connection Services (DECS) set and use certain environment variable settings in the notes.ini file. Some of these variables are set based on choices you make during the Domino or HEI installation. You can use the notes.ini file to change these settings for DECS and HEI.
