Variable type conversion for a view | varchar (max) to (250)

Question

Is it possible to convert varchar(max) in a table to varchar(250) in a view?

Id type int
Textxxx type varchar(max)

dbo.Table:

Id | textxxx
—--+------
 1 | aaaa
 2 | bbbb

Query

CREATE VIEW dbo.view
    SELECT ALL [Textxxx] 
    FROM DBO.Table
go

And I want to convert this text (varchar(max)) to varchar(250)

Totally I don't know how to do it, should I use:

CONVERT([Text], varchar(250))

???

You can use CAST or CONVERT function.

Below you can find the example

CREATE OR ALTER VIEW dbo.ViewsText
AS
    SELECT 
                ID
                ,TextWithCast = CAST(textxxx AS varchar(250)
                ,TextWithConvert = CONVERT (varchar(250), textxxx)
FROM 
         dbo.Table
                

Conversion from large-value data types, such as varchar(max), to a smaller counterpart data type, such as varchar, is an implicit conversion, but truncation occurs if the size of the large value exceeds the specified length of the smaller data type.
