Resolving ORA-01036 Error When Calling PL/SQL Function with Node.js

When working with Oracle PL/SQL functions in a Node.js application, you may come across the frustrating ORA-01036: illegal variable name/number error. This error typically indicates that there is a problem with the binding of variables you are passing to your SQL statement. In this guide, we will discuss the common causes of this error and how to effectively resolve it.

Understanding the Problem

The ORA-01036 error can occur when the names of the bind variables in your SQL statement do not match the names specified in the bind parameters, or when you fail to provide the required number of bind variables in your call.
