Troubleshooting the node data type
Error message specific to the node data type have the prefix UND. You can enable tracing on the node data type to diagnose problems.
You might receive the following errors:
| Error | Description |
|---|---|
| UNDE1: Invalid input string. | A node is invalid. Nodes cannot end in 0. |
| UNDE2: Illegal character found in input string. | An argument contains an illegal character. Nodes can contain only numeric characters. |
| UNDE3: Third input parameter is not descendant of first input parameter. | The third argument of a Graft function is not a descendant of the first argument. |
| UNDE4: Index to node element should be greater than or equal to 1. | A problem exists with the node indexing. |
To enable tracing, create a trace class by inserting
a record into the systemtraceclasses system catalog:
INSERT INTO informix.systraceclasses(name) VALUES ('Node'); For more details regarding tracing, see the HCL OneDB™ Guide to SQL: Reference.
