TableOperationsTQueryRecords(String, RecordRestriction, Int32) Method

Queries database and returns modeled table records for the specified parameters.

Definition

Namespace: Gemstone.Data.Model
Assembly: Gemstone.Data (in Gemstone.Data.dll) Version: 1.0.110 -- Release Build+b4bcf74734aa051a9b802d8f3f6ec05bd02af749
public IEnumerable<T> QueryRecords(
	string? orderByExpression = null,
	RecordRestriction? restriction = null,
	int limit = -1
)

Parameters

orderByExpression  String  (Optional)
Field name expression used for sort order, include ASC or DESC as needed - does not include ORDER BY; defaults to primary keys.
restriction  RecordRestriction  (Optional)
Record restriction to apply, if any.
limit  Int32  (Optional)
Limit of number of record to return.

Return Value

IEnumerableT
An enumerable of modeled table row instances for queried records.

Remarks

If no record restriction or limit is provided, all rows will be returned.

If any of the restriction parameters reference a table field that is modeled with either an EncryptDataAttribute or FieldDataTypeAttribute, then the function GetInterpretedFieldValue(String, Object) will need to be called, replacing the target parameter with the returned value so that the field value will be properly set prior to executing the database function.
