Yes you cannot create a table with out assigning a datatype to a column, the Management studio is designed like that.

Surprising .. :-)

hi sir,

i also agree with Zoheb Mohammeds query.bcoz using script it works fine.but when i am trying to use same logic in design mode then it shows invalid data type error.

Hi Pinal,

I have used c1 and c2 instead of ! and !!.

CREATE TABLE MyTabs ([c1] INT, [c2] AS [c1]);—Works fine
INSERT INTO MyTabs VALUES (1);—shows 1 row affected
SELECT * FROM MyTabs1—No inserted records are displayed,only empty table.

Deepraj

Hi pinal sir,
i have a small question.
what you did is throught a script
[here i m focussing on second column]
after running the script and opened the table in design mode i can see the data type for second column is blank/empty.
if i try to make the same table structure through designer, it wont let me proceed unless i specify the data type or i cannot keep the data type blank.

so how can i create a table in designer mode rather than Query mode, to full fill this requirement. thanks
