Class UDefFieldRows

Definition table for user-defined fields; one row in this table corresponds to one generation of one field. The user defined fields that are in use, and earlier versions of user defined fields. ColumnId refers to the field type; see UDXXXSmall or UDXXXLarge for the referring ID. Preferences prefsection='System', prefkey='CurrentUdefVersioncontact' (or CurrentUdefVersionperson, project, sale), gives you the current version of user defined fields. prefkey='AdminUdefVersion<...>' gives you the current version that's being edited. If Current version = admin version, no editing has been done since the last Publish of user defined field was performed. Collection of UDefFieldRow. Each element of the collection represents one row in the UDefField table.

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 UDefFieldRow to it, and use methods like Save to operate on the whole collection.
  • You can create a (nested) UDefFieldRows UDefFieldRows.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 UDefFieldRow object directly, which has nested classes and GetFromIdx methods for each unique index. Similarly, there is a GetFromReader(SoDataReader, UDefFieldTableInfo) 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).

GetFromIdxOwnerTableId(short)

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

Declaration

Parameters
Type Name Description
short ownerTableId
Returns
Type Description
UDefFieldRows

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

GetFromReader(SoDataReader, UDefFieldTableInfo)

Create a new instance of the UDefFieldRows 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 UDefFieldRow 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.

SoDataReader reader

SoDataReader positioned to a valid database row.
