18.4.142.1 Query grammar (5.3.2.3)

The Query Profile shows a query grammar. This is a brief model of the segments used in the query message.

• Message
• ACK Choreography
• FHIR Structure Definition
• v2.xml XSD
• ER7 Example
• XML Example

Segment	Cardinality	Implement	Status
QBP^Znn^QBP_Qnn
MSH Message Header	[1..1]	SHALL
SFT Software Segment
UAC User Authentication Credential Segment	[0..1]
QPD Query Parameter Definition	[1..1]	SHALL
RDF Table Row Definition	[0..1]
RCP Response Control Parameter	[1..1]	SHALL
DSC Continuation Pointer	[0..1]

 

QBP_Qnn

MSH-15	MSH-16	Immediate ACK	Application Ack
Blank	Blank	-	RTB^Znn^RTB_Knn
NE	AL	-	RTB^Znn^RTB_Knn
AL, SU, ER	AL	ACK^Znn^ACK	RTB^Znn^RTB_Knn

Query Grammar: This and the following column specify the HL7 code name and full name of each segment sent in the query. Braces specify that the segment or segment group is repeatable; brackets specify the optionality of the segment or segment group.

Section Reference: Specifies where in the standard further information about the segment can be found.

When the Query by Example variant is used, the Query Grammar shows the segments that may be used to transmit parameters and the order in which they appear. Segments used to transmit parameters are always sent immediately following the QPD segment.
