Class RelationsRows

Instance of a relation, in principle between any two records, as long as they are defined in RelationDefinition. All instances of relations are held in this table; their definitions are in the RelDef table (RelDef + RelTarg define which relations you can have, this table contains the relations the user has actually entered). From 6.1 all links between appointments, sales and documents are also stored in this tabel. Collection of RelationsRow. Each element of the collection represents one row in the Relations table.

Syntax

public class RelationsRows : TableRowsBase, INestedPersist, IEnumerable<INestedPersist>, ISoCollection, 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 RelationsRow to it, and use methods like Save to operate on the whole collection.
• You can create a (nested) RelationsRows RelationsRows.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 RelationsRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, RelationsTableInfo) 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).
