RecordRestriction Constructor

public RecordRestriction(
	string? filterExpression,
	params Object?[]? parameters
)

Public Sub New ( 
	filterExpression As String,
	ParamArray parameters As Object()
)

public:
RecordRestriction(
	String^ filterExpression, 
	... array<Object^>^ parameters
)

Gemstone.Data.Model.RecordRestriction = function(filterExpression, ... parameters);

Parameters

filterExpression  String

Filter SQL expression for restriction as a composite format string - does not include WHERE. When escaping is needed for field names, use standard ANSI quotes.

parameters  Object

Restriction parameter values.

Each indexed parameter, e.g., "{0}", in the composite format filterExpression will be converted into query parameters where each of the corresponding values in the parameters collection will be applied as IDbDataParameter values to an executed IDbCommand query.

If any of the 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 any database function.

If needed, field names that are escaped with standard ANSI quotes in the filter expression will be updated to reflect what is defined in the user model.
