Returns the value of an attribute of a structured type that is defined to be an input parameter to a UDF, UDM, or external stored procedure.
The attribute must be one of the following types:
- Non-LOB predefined type, such as INTEGER or VARCHAR
- Distinct UDT
- Structured UDT
- JSON
To get the value of a LOB attribute of a structured type, use the C library routine FNC_GetStructuredInputLobAttributeByNdx.
For best performance, use FNC_SetStructuredAttributeByNdx instead of this routine. This routine is supported for ease of use.
