Various functions are available in a
Mapping node.
These are either provided within the
Mapping node or
user-defined. The functions that are provided with the
Mapping node are
of the following types:
- ESQL - prefixed esql:
- XPath - prefixed fn:
- Mapping - prefixed msgmap:
- Schema casts - prefixed xs:
Not all ESQL functions can be used in a
Mapping node.
For information about which functions are supported, and for a description
of how to achieve equivalent processing for ESQL functions that are not supported,
see the
ESQL topics.
An additional capability provided by the mapping
node is the ability to set the value of a target to a WebSphere MQ constant.
The expression to set the value looks similar to a function with $mq: used
as the prefix.
