Properties

	Name	Description
	CanBePacked	Gets a value signalling whether this query can be packed in a packed query (true) or not (false). A query can be packed if it's not a batchquery and there are no parameter-parameter relations pending or parameter-field relations with self.
	Command	The command used for this query. (Inherited from Query.)
	Connection	The connection object to use with the Command (Inherited from Query.)
	ExecuteThroughDbDataReader	If true (Default false) it will execute the command through ExecuteReader instead of ExecuteNonQuery and will assume output parameters are part of one or more resultsets. Output parameters are expected to be added through AddOutputParameterForReader(DbParameter), and are set through ordinal (so first parameter is set with value at ordinal 0).
	ForcedReturnValue	Gets or sets the forced return value. If smaller than 0, the value returned by the command is used, otherwise this value. Set by DQEs which know up front the query won't return a valid return value, because batching is used.
	OutputParametersForReader	Gets the set of parameters set for the dbdatareader fill procedure. these parameters are added through AddOutputParameterForReader(DbParameter) and aren't part of the command.
	ParameterFieldRelations	List with the IParameterFieldRelation instances for the relations between entity fields and output parameters. (Inherited from Query.)
	ParameterParameterRelations	Gets the parameter parameter relations for this IActionQuery. These definitions are used for insert queries in multi-target entity inserts.
	Parameters	The list of parameters used in the Command. (Inherited from Query.)
	ReturnValueParameter	If set, it will be used for the value returned in ExecuteNonQuery and will override the value ExecuteNonQuery returns or which is set in ForcedReturnValue.
	SequenceRetrievalQueries	Array list of ISequenceRetrievalQuery objects which are used to produce sequence values for input/output parameters in this query. Normally this collection is empty, as it is only used when the target database provider doesn't support batched queries (firebird/access/sqlce and others). Execute will wire the transaction if present.

Methods

	Name	Description
	AddOutputParameterForReader	Adds the specified parameter to the set of output parameters for a dbreader exectured query. These parameters aren't part of the dbcommand, and are filled with resultsets. All parameters are expected in each resultsets returned by the dbdatareader returned when this query is executed.
	AddOutputParameterValueForSync	Adds the output parameter value for synchronization with the enclosed DbParameter, after the query has been executed. (Inherited from Query.)
	AddParameter	Adds the parameter to the query's command. (Inherited from Query.)
	AddParameterFieldRelation(IEntityFieldCore, DbParameter, TypeConverter)	Adds a new IParameterFieldRelation to the collection of ParameterFieldRelations. An output parameter can be stored once in the collection. (Inherited from Query.)
	AddParameterFieldRelation(IEntityFieldCore, DbParameter, TypeConverter, Boolean)	Adds a new IParameterFieldRelation to the collection of ParameterFieldRelations. An output parameter can be stored once in the collection. (Inherited from Query.)
	AddParameters	Adds the parameters to the query's command. (Inherited from Query.)
	AddSequenceRetrievalQuery(DbCommand, Boolean)	Adds a new sequence retrieval query to this query
	AddSequenceRetrievalQuery(DbCommand, Boolean, Boolean)	Adds a new sequence retrieval query to this query
	AddSequenceRetrievalQuery(DbCommand, Boolean, ListDbParameter)	Adds a new sequence retrieval query to this query
	AddSequenceRetrievalQuery(DbCommand, Boolean, Boolean, ListDbParameter)	Adds a new sequence retrieval query to this query
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from Query.)
	Dispose(Boolean)	Performs the dispose action. (Overrides QueryDispose(Boolean).)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Execute	Executes the query contained by the IQuery instance. If there was nothing to execute, 0 is returned.
	ExecuteAsync	Async variant of Execute. Executes the query contained by the IQuery instance.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetExceptionInfo	Gets the exception info using the info retriever set to this query object. (Inherited from Query.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MergeInto	Merges all data of query into this query's QueryToExecute. It moves parameters and other elements. Query is after this not usable anymore.
	MergeParameterFieldRelations	Merges the passed in elements in toMerge into this instance. It's up to the caller to remove the elements from the set passed in. (Inherited from Query.)
	ReflectOutputValuesInParameterValues	Reflects the output values of output parameters in parameter values, if any. (Inherited from Query.)
	ReflectOutputValuesInRelatedFields	Will walk all IParameterFieldRelation instances of this query and reflect the parameter values in the related fields. Only output parameters are taken into account. Used by Insert queries which retrieve Identity / sequence values back from the database after a succesful insert. (Inherited from Query.)
	SetCommandText	Sets the command text to the text specified (Inherited from Query.)
	SetCommandTimeout	Sets the command timeout. (Inherited from Query.)
	ToString	Produces a string representation of this query. (Overrides QueryToString.)
	ToString(Boolean)	Overloaded ToString implementation (Inherited from Query.)
	WireTransaction	Wires the command of this query with the transaction passed in. (Inherited from Query.)
