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.
