Components: <field name (ST) > ^ <value1 (ST) & value2 (ST) & value3 (ST) ...>
Definition: This field contains the list of parameter names and values to be passed to the stored procedure.
This component contains the field name.
Field naming conventions:
Fields are designated by the "@" symbol concatenated with the HL7 item number for the field. If the field is divided into components, the designation may be suffixed with ".nn," to identify a particular component (a suffix of ".3" indicates the third component of the field); otherwise, the whole field is assumed. If the field is further divided into subcomponents, the designation is suffixed with ".nn.mm," which identifies the component and subcomponent requested by relative position.
Site-specific fields may be used, provided that they begin with the letter "Z." In this case, site-specific item numbers must be defined that do not conflict with existing HL7 item numbers.
Values for this field are defined in the function-specific chapters of this specification.
Note: If the "@" is being used as one of the delimiter characters defined in MSH-2-encoding characters, it must be "escaped ." (See Section 2.9.1," Formatting codes".) |
This component contains the field value or values in the form "value1& value2 & value3 "
A single valued parameter contains only a single subcomponent in the second component: thus no subcomponent delimiters are needed (e.g., <field name> ^ <value>). A simple list of values (i.e., a one-dimensional array) may be passed instead of a single value by separating each value with the subcomponent delimiter: ,"<field name> ^ <value1 & value2 & >"
