Specifying an Existing UDR

To reference an existing UDR by a name that does not uniquely identify the UDR, you must also specify the parameter data types after the UDR name, in the same order that they were declared when the UDR was created. HCL OneDB™ then uses routine resolution rules to identify the instance of the UDR to alter, drop, or execute. As an alternative, you can specify its specific name, if one was declared when the UDR was created. Specific names are described in the section Specific Name. For more details of routine resolution, see Comparing Arguments to the Parameter List, and HCL OneDB User-Defined Routines and Data Types Developer's Guide.
