Msg 4511 Level 16 - Create View or Function failed because no column name was specified


Transact-SQL error message Msg 4511 Level 16 - Create View or Function failed because no column name was specified - means that in your view exist an concatenated column composed of multiple columns and has not declared an alias.

The error message itself is quite clear: it is telling you that you are trying to create a view or function without specifying column names for one or more of the output columns. SQL Server requires that every column in a view or function must have a name assigned to it.


Msg 4511 Level 16 Example

Here's an example of what this error might look like in SQL code:


Invalid create view:

USE model;
GO
CREATE VIEW studentsList AS
SELECT id, CONCAT(first_name,' ',last_name), gender
FROM students
GO

Message

Correct create view:

USE model;
GO

FROM students
GO

Message
