Oracle ORA-28555: Missing Parameter
Description
The ORA-28555 error in Oracle Database indicates that a required parameter in a pass-through SQL statement is either missing or contains a NULL value. This error typically arises when integrating with external systems or using heterogeneous services where parameter values are not properly validated before being passed to the target database.
Error Message
ORA-28555: pass-through SQL: required parameter missing or NULL
Known Causes
3 known causesNULL Parameter Value
A parameter defined as NOT NULL in the target system received a NULL value during the pass-through operation. This violates the target system's data integrity constraints.
Missing Parameter Definition
The pass-through SQL statement references a parameter that was not defined or included in the parameter list. This leads to the target system not receiving the expected value.
Incorrect Parameter Mapping
The parameter mapping between the Oracle database and the external system is incorrect. This can result in NULL values being passed when they shouldn't be.
