Class OLEViewRows
Control data table for the OLE DB Provider Collection of OLEViewRow. Each element of the collection represents one row in the OLEView table.
Inheritance

Inherited Members
Namespace: SuperOffice.CRM.Rows
Assembly: SoDataBase.dll
Syntax
public class OLEViewRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, INotifyCollectionChanged, IBindingList, IList, ICollection, IEnumerable
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 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.

GetFromIdxOLESubjectIdAsync(int, CancellationToken)
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 Task<OLEViewRows> GetFromIdxOLESubjectIdAsync(int oLESubjectId, CancellationToken cancellationToken = default)
Parameters
| Type | Name | Description |
|---|---|---|
| int | oLESubjectId | |

|---|---|
| Task<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.
GetFromReaderAsync(SoDataReader, OLEViewTableInfo, CancellationToken)
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 Task<OLEViewRows> GetFromReaderAsync(SoDataReader reader, OLEViewTableInfo tableInfo, CancellationToken cancellationToken = default)
Parameters
| Type | Name | Description |
|---|---|---|
| SoDataReader | reader | SoDataReader positioned to a valid database row. |

Returns
| Type | Description |
|---|---|
