Class KbAttachmentRow

This table connects FAQ entries to attachments.
Row Object for table 'kb_attachment'. 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 KbAttachmentRow : 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) KbAttachmentRow KbAttachmentRow.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(KbAttachmentRow.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 KbAttachmentTableInfo instance used in the query behind the reader, you can use the static GetFromReader(SoDataReader, KbAttachmentTableInfo) 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 KbAttachmentRows collection, which has nested classes and GetFromIdx methods for each non-unique index. Similarly, there is a GetFromReader(SoDataReader, KbAttachmentTableInfo) method to retrieve the results of queries that return more than one row.

Methods

CreateNew()

Create a new instance of the KbAttachmentRow object. This table connects FAQ entries to attachments.

Declaration
public static KbAttachmentRow CreateNew()
Returns
Type Description
KbAttachmentRow

A new instance of the KbAttachmentRow object.

GetFromCustomSearch(KbAttachmentRow.CustomSearch)

Create a new instance of the KbAttachmentRow 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 KbAttachmentRow GetFromCustomSearch(KbAttachmentRow.CustomSearch query)
Parameters
Type Name Description
KbAttachmentRow.CustomSearch query

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

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

GetFromIdxKbAttachmentId(Int32)

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

Declaration
public static KbAttachmentRow GetFromIdxKbAttachmentId(int kbAttachmentId)
Parameters
Type Name Description
Int32 kbAttachmentId
Returns
Type Description
KbAttachmentRow

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

GetFromReader(SoDataReader, KbAttachmentTableInfo)

Create a new instance of the KbAttachmentRow 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. This table connects FAQ entries to attachments.

Declaration
public static KbAttachmentRow GetFromReader(SoDataReader reader, KbAttachmentTableInfo tableInfo)
Parameters
Type Name Description
SoDataReader reader

SoDataReader positioned to a valid database row.
KbAttachmentTableInfo tableInfo
