Each entry in this table is one such result-set. Result-sets are kept in this table, so that client-stations can call Remote Procedures to obtain the content of a result-set in portions of a limited size. Also, since the creation of a result-set may need more time than is reasonable wait for in a single Remote Procedure Call, the existence of this table makes it possible to call a first Remote Procedure to create the result-set through a TaskMan process and then call subsequent Remote Procedures to inquire whether the result-set is complete, and subsequently to obtain the results.
.01result(+)0;1NUMERICBThe value of this field is an integer number. This number uniquely identifies a result-set that results from a DICOM Query/Retrieve request. The rest of the record is the result-set in question.
2status0;2SET OF CODESIP:Query in progress
OK:Query complete
X:Query completely reported
The value of this field is a code that indicates the status of a query. When a query is initiated, the value of this field will be set to IP = In Progress. When a query is complete, the value of this field will be changed to OK = Query Complete. When all results that are logged for the query have been reported, the value of this field will be set to X = Query Completely Reported, so that a clean-up process may remove the now obsolete result-set. (See also the field TIMESTAMP.)
3timestamp0;3DATE-TIMEThe value of this field is a timestamp that indicates when a result-set was last accessed. This value is set to the current date and time when the result-set is first marked as complete, and will be updated each time a (partial) result is reported. The main purpose of this field to to assist a maintenance process in cleaning up result-sets that haven't been accessed in more than a couple of days.
5taskman0;4NUMERICThe value of this field is a number. This number is returned by TaskMan when a new background process is created to perform the actual query. This number will be used to query TaskMan to see whether the background process has completed. Note: if the background process is no longer active, and no result-set has been delivered, the error log should be checked for any problems.
