Class RelationTargetRow

Definition of targets for a relation. Links a relation definition (RelDef) to source and target tables. In general, a relation can be created between any pair of tables. This table is used for specifying which table pairs a particular relation can be used for. A relation definition should have at least one row in this table, and can have more. Note: The 5.0 Maintenance and GUI only support contact and person as valid values for the source_table and destination_table fields, in any combination. Other relations will not be shown, and relation definitions pointing to other tables will not be editable from the Maintenance GUI; however, nothing will crash.
Row Object for table 'relationtarget'. Row objects correspond directly to database tables, and one instance of a row object represents one row in the corresponding table in the database.

Syntax
public class RelationTargetRow : TableRowBase, INestedPersist, ISoDataLookup, ISentryIgnorable, ISoItem
Remarks

Row objects can be created in several ways.

  • Use the static CreateNew() method to create a new, empty object. After populating it with values, you call the method and a corresponding row in the database is created, and the objects' primary key field updated. This is the preferred way to insert new rows into the database.
  • You can create a (nested) RelationTargetRow RelationTargetRow.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(RelationTargetRow.CustomSearch) method to apply the query to the database and obtain the result as a Row object. This is how you select existing rows from the database when you have a query that does not correspond to any of the existing database indexes.
  • For each unique index defined for the table, there is a corresponding GetFromIdx method to make retrieving data via the indexes easy. Note that if you try to fetch a row that does not exist (for instance, by using the primary key index and specifying a primary key that does not exist in the database), you will get a Row object with the and properties set to true. Such a Row object is called a 'ghost' and cannot be updated, saved or deleted. You can also get a ghost if the row does exist in the database, but the Sentry system denies Select rights to the row.
  • Finally, if you have an SoDataReader that contains ALL the fields of the table, and you have the RelationTargetTableInfo instance used in the query behind the reader, you can use the static GetFromReader(SoDataReader, RelationTargetTableInfo) method to create a new row object from the reader and the table info. This is useful when you have a larger, more complex query, for instance one that joins a number of tables, and you wish to use Row objects to process the result set. If your result set corresponds to an entity, consider using the corresponding Entity layer object instead, since entities automatically handle ID allocation and mapping, rights, and other higher-level aspects.
Non-unique indexes are handled through the RelationTargetRows collection, which has nested classes and GetFromIdx methods for each non-unique index. Similarly, there is a GetFromReader(SoDataReader, RelationTargetTableInfo) method to retrieve the results of queries that return more than one row.

Unique indexes on table RelationTarget are:

Methods

CreateNew()

Create a new instance of the RelationTargetRow object. Definition of targets for a relation. Links a relation definition (RelDef) to source and target tables. In general, a relation can be created between any pair of tables. This table is used for specifying which table pairs a particular relation can be used for. A relation definition should have at least one row in this table, and can have more. Note: The 5.0 Maintenance and GUI only support contact and person as valid values for the source_table and destination_table fields, in any combination. Other relations will not be shown, and relation definitions pointing to other tables will not be editable from the Maintenance GUI; however, nothing will crash.

Declaration
public static RelationTargetRow CreateNew()
Returns
Type Description
RelationTargetRow

A new instance of the RelationTargetRow object.

GetFromCustomSearch(RelationTargetRow.CustomSearch)

Create a new instance of the RelationTargetRow object, and populate it with data from a custom search. If the search returns no results, an object with IsNew will be returned; if the result contains one row, an object representing that row will be returned. If the result contains more than one row, the first row will be used and the rest discarded (there is no way of detecting this situation).

Declaration
public static RelationTargetRow GetFromCustomSearch(RelationTargetRow.CustomSearch query)
Parameters
Type Name Description
RelationTargetRow.CustomSearch query

The custom search to execute against the database
Returns
Type Description
RelationTargetRow

A new instance of the RelationTargetRow object, reflecting the result of the query.

GetFromIdxReltargetId(Int32)

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

Declaration
public static RelationTargetRow GetFromIdxReltargetId(int reltargetId)
Parameters
Type Name Description
Int32 reltargetId
Returns
Type Description
RelationTargetRow

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 RelationTarget table. Non-unique indexes have corresponding inner classes and methods in the RelationTargetRows collection, since they may return more than one row.

GetFromReader(SoDataReader, RelationTargetTableInfo)

Create a new instance of the RelationTargetRow object, and populate it with data from a reader/tableinfo. If the reader has DBNull as the current value of the primary key field, an unpopulated object with IsNew == true will be returned. If any fields are missing or one of the non-primary key fields is DBNull, an exception will be thrown. Definition of targets for a relation. Links a relation definition (RelDef) to source and target tables. In general, a relation can be created between any pair of tables. This table is used for specifying which table pairs a particular relation can be used for. A relation definition should have at least one row in this table, and can have more. Note: The 5.0 Maintenance and GUI only support contact and person as valid values for the source_table and destination_table fields, in any combination. Other relations will not be shown, and relation definitions pointing to other tables will not be editable from the Maintenance GUI; however, nothing will crash.

Remarks

If the row is not persisted to the database (e.g. IsNew is true), all the values will be reset. If the row has been persisted to or loaded from the database, the properties will be set to those of the last persisted or loaded values.

SetDefaults(DefaulterStrategy)

Set default values for the row.

Declaration
public override void SetDefaults(DefaulterStrategy strategy)
