Assigns values to one or more of the attributes of a specified instance. This operation is applicable only to Explicit attributes, not to Inverse or Derive attributes. The attributes are identified by their attributeIds.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiAppInstance	instance	A numeric instanceID that uniquely identifies an instance in the remote EDMdatabase
SdaiInteger	attributes	The number of attributes for which to assign values.
SdaiInvocationId	edmiInvocationId	Currently not used.
	values	For each attribute value to assign the three following arguments in the following order have to be specified: SdaiAttr attributeID: A numeric identifier that uniquely identifies an attribute definition instance in the remote EDMdatabase SdaiPrimitiveType valueType : The primitive type of the <value> argument. This type must be must be the same or compatible with the data type of the actual attribute domain as it is defined in the attribute declaration of the underlying Express Schema. All data types except sdaiAGGR can be handled by this operation. Aggregates may not be assigned to attributes by this operation. They must be created explicitly by appropriate aggregate operations. sdaiSELECT can be used to write all data types. sdaiADB can be used to write all data types except typed values. sdaiINTEGER is compatible with sdaiREAL. sdaiBOOLEAN is compatible with sdaiLOGICAL. Conversion between compatible data types will be performed automatically when required. SdaiVoid value : The data value to assign to the attribute of the specified instance. The type of <value> must be the same as specified in the <valueType> argument.
