MS SQL Server View not allowing CONCAT

Question

MS SQL Server 2014.

I have a SQL statement that works fine:

SELECT CONCAT (
        CAST(T1.[F1] AS INTEGER),
        CAST(T1.[F2] AS INTEGER)
        )          


        

Answer 1

Don't use the visual designers.

They are buggy and in this case convert

    SELECT CONCAT (
        CAST(T1.[F1] AS INTEGER),
        CAST(T1.[F2] AS INTEGER)
        ) AS F3 
FROM mytable AS T1

to

SELECT { fn CONCAT(CAST(T1.F1 AS INTEGER), CAST(T1.F2 AS INTEGER)) } AS F3
FROM     mytable AS T1

Calling the highly limited ODBC escape sequence version of the function (that only accepts two parameters which must be strings)

Just use a standard new query window to execute your CREATE VIEW/ALTER VIEW/SELECT FROM operations and you won't get this issue.
