Feature Proposal: Column-Level DELETE Operation in SQL

[Abhishek Hatgine <hatgineabhishek99@xxxxxxxxx>]

Dear SQL Development Team,

I hope this message finds you well.

I'd like to propose a new feature for consideration in future versions of SQL — the ability to perform a column-level DELETE operation, allowing removal of specific column values without affecting the entire row.

Proposal Summary

Currently, SQL provides two core commands:

• DELETE – to remove entire rows.

• UPDATE – to change or nullify column values.

However, there’s no specific, expressive way to delete the value of a column directly. The typical workaround is to use:

UPDATE Customers SET Address = NULL WHERE CustomerID = 103;

While this works fine, it doesn't semantically express that the developer intends to remove the value — not just update it.

Proposed Syntax Examples

Here are some ideas for possible new syntax:

DELETE Address FROM Customers WHERE CustomerID = 103;
-- or
REMOVE COLUMN Address FROM Customers WHERE CustomerID = 103;

And even:

DELETE Address, PostalCode FROM Customers WHERE Country = 'India';

These would act as a shortcut or expressive alias for setting one or more column values to NULL.

Why This Matters

• Improved readability and code clarity.

• More intuitive for developers coming from languages or NoSQL systems where fields can be "deleted" from an object/document.

• Emphasizes intent: deleting a value is conceptually different from updating it to NULL.

• Opens doors for potential enhancements in tooling and IDE support.

I understand this would require careful consideration within the SQL standards, but I believe it could make SQL more expressive and beginner-friendly while preserving its power.

Thank you for your time and for all the work you do to maintain and improve SQL systems.

Warm regards,
