Remarks

Row collections can be created in several ways.

  • Use the static CreateNew() method to create a new, empty collection. You can then add objects of type OLEViewRow to it, and use methods like Save to operate on the whole collection.
  • You can create a (nested) OLEViewRows OLEViewRows.CustomSearch object to obtain a query pre-populated with the correct tableinfo and return fields. This query can be modified with restrictions, etc. Then, use the static GetFromCustomSearch(CustomSearch) method to apply the query to the database and obtain the result as a Rows object, with one item for each table row that matched your query.
  • For each non-unique index defined for the table, there is a corresponding GetFromIdx method to make retrieving data via the indexes easy.
Unique indexes are handled through the OLEViewRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, OLEViewTableInfo) method to retrieve the results of queries that return more than one row (this method will iterate over the reader to fetch ALL results, so beware of fetching huge result sets).

GetFromIdxOLESubjectId(int)

Create a new instance of the OLEViewRow object, by querying the database table via the index 'IDXOLEViewOLESubject_id'. This method is intended to make it easy to use efficient queries that match a database index.

Declaration
public static OLEViewRows GetFromIdxOLESubjectId(int oLESubjectId)
Parameters
Type Name Description
int oLESubjectId
Returns
Type Description
OLEViewRows

Row object that represents the result of the search. IsNew will be true if the query did not match any row in the table
Remarks

This method represents one of the unique indexes on the OLEView table. Non-unique indexes have corresponding inner classes and methods in the OLEViewRows collection, since they may return more than one row.

GetFromReader(SoDataReader, OLEViewTableInfo)

Create a new instance of the OLEViewRows object, and populate it with data from a reader. If the search returns no results, an empty collection will be returned; if the result contains rows, a collection of OLEViewRow objects representing each row will be returned.

Note that the internal logic starts by calling reader.Read(), which is correct if you hand the method the result of an ExecuteReader(), but if the reader has already been advanced one or more rows, the current row will be skipped and collection population will start with the next row.
Declaration
public static OLEViewRows GetFromReader(SoDataReader reader, OLEViewTableInfo tableInfo)
Parameters

SoDataReader reader

SoDataReader positioned to a valid database row.
