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.

      - LCFieldlist class overview
        The LCFieldlist class represents metadata (the description of data from a data source) for a record and may reference data, in the form of LCFields, for one or more record values. A fieldlist is a list of fields and field names with a represented order. Fields within a fieldlist can be added, modified, retrieved, or listed in multiple ways. The fields, field names, and order are separate entities and only have relation within an individual fieldlist.
      - Syntax for HEI Scripted Activities - 2
        When writing LotusScript® Extensions (LC LSX) scripts for HCL Enterprise Integrator (HEI) Scripted activities, you must specify Dim LCSession as a named session (this becomes the default log document name). LCConnections must also be dimensioned as existing, named HEI connection documents.
      - Accessing Field Data
        Field data within an LCFieldlist object may be accessed as a property by name. The data type of the property depends on the data type of the field. The property is an array of LotusScript® data types, as shown in the table as follows. For example, if a fieldlist has a field named OrderID, its first value may be obtained with the following script:
      - Fieldlist Merging and Mapping
        Fieldlist merging with LCFieldlistMerge and LCFieldlistMergeVirtual support field mapping. To perform mapping, two fieldlists are provided, one as the name source and the other as the field/data source. Depending on merge options, a mapping is produced between the names of the name source and the fields of the data source, and a third fieldlist is produced which references parts of the original fieldlists. When using virtual fields and LCFieldlistMergeVirtual, fields in the data fieldlist which match the supplied virtual code are excluded from mapping and are added to a separate new virtual fieldlist.
      - LCFieldlist Class Methods Summary
        The LCFieldlist class method is summarized here.
      - New Method for LCFieldlist
        This is the constructor for LCFieldlist.
      - Append Method for LCFieldlist
        This method creates a new field and appends it to an existing fieldlist.
      - Copy Method for LCFieldlist
        This method creates a duplicate copy of an LCFieldlist and all its data. Every field in the LCFieldlist is also duplicated, so you don't end up with two fieldlists that both refer to the same LCField objects.
      - CopyField Method for LCFieldlist
        This method copies an existing field and inserts a copy of the field within a fieldlist at a specified position.
      - CopyRef Method for LCFieldlist
        This method creates a new fieldlist object instance as a partial copy of another fieldlist. The fields in the original fieldlist are not copied, but are referenced.
      - GetField Method for LCFieldlist
        This method gets a field reference from a specified position in a fieldlist and places its value into a variable.
      - GetName Method for LCFieldlist
        This method obtains a copy of the name of a field within a fieldlist.
      - IncludeField Method for LCFieldlist
        This method includes an existing individual field in a fieldlist.
      - Insert Method for LCFieldlist
        This method inserts a new field into an existing fieldlist at a specified index position.
      - List Method for LCFieldlist
        This method retrieves information about one field in the fieldlist. By calling it repeatedly, you can iterate through the fields in the list.
      - Lookup Method for LCFieldlist
        This method locates a field from a fieldlist based on field name.
      - Map Method for LCFieldlist
        This method copies field references from one field list, into another field list. It's similar to the CopyRef method, except that you specify the names of fields you want to create new references to.
      - MapName Method for LCFieldlist
        This method maps fields with different names. Use this method for field mapping operations when the fieldnames are different in the source and target. This allows you to change field order and also exclude fields.
      - Merge Method for LCFieldlist
        This method merges two fieldlists, copying the names from one and taking the field objects from another to fill in a third mapping fieldlist. Use this method for field mapping operations when you either have a name fieldlist already built and/or you need to use fieldlist flags.
      - MergeVirtual Method for LCFieldlist
        This method merges two fieldlists to create new mapping and virtual fieldlists.
      - Remove Method for LCFieldlist
        This method removes an existing field from a fieldlist. This does not remove a column from associated metadata. See the earlier section entitled "Fieldlist Merging and Mapping" for related information about how removing or adding columns to a result set affects Fetch, Insert and other operational methods.
      - Replace Method for LCFieldlist
        This method creates a new LCField object and puts it into the fieldlist in place of an existing field. The data from the old field is not copied into the new field.
      - SetName Method for LCFieldlist
        This method changes the name of a field within a fieldlist.

MergeVirtual Method for LCFieldlist

This method merges two fieldlists to create new mapping and virtual fieldlists.

Note: This method is provided for backward compatibility. We recommend that you use either the Map or MapName methods for merging fieldlists and creating new mappings.

Defined In

LCFieldlist

Syntax

Call fldList. MergeVirtual (nameFieldList, dataFieldList, MergeFlags, virtualCode, virtualFieldList)

Parameters

Parameters are described in the following table.


Parameter	Description
nameFieldlist	LCFieldlist. Source fieldlist containing the field list of names for the new fieldlist.
