How can I solve the issue of “SQLCODE206 SQLSTATE 42703”?

In the context of SQL the particular error of “SQLcode206 SQLstate 42703” can be due to attempting to reference a column that specifically doesn’t exist in the referenced table. To solve this issue, you should check your SQL code so that you can ensure that the column name referenced matches your query or not.

For example, consider a scenario where you encountered this particular error while creating a table with foreign keys and the reference doesn’t match with the queries, you may have a statement like this:-

CREATE TABLE Orders (
    OrderID INT PRIMARY KEY,
    CustomerID INT,
    OrderDate DATE,
    FOREIGN KEY (CustomerID) REFERENCES Customers(Customer_ID) – Error due to mismatched column name
);

To fix this problem ensure that the column names are matched with the referenced names. In this process you might have a structure like this:-

CREATE TABLE Orders (
    OrderID INT PRIMARY KEY,
    CustomerID INT,
    OrderDate DATE,
    FOREIGN KEY (CustomerID) REFERENCES Customers(CustomerID) – Corrected column name
);

By following this above structure you can get rid of SQLcode206 SQL state 42703 error.
