Solution 3

DECLARE @Count BIGINT
SELECT @Count=COUNT (*) FROM Table1
SET @Count = @Count +1
insert into Table1 (Column2) Values (@Count);

Above must be in one line.

nice one.

i think we can use this also
select @Count=Max(Column1) From Table1

This two (I mean my answer and your answer) have some limitations. Because both of the cases need the logical deletion. If physical deletion occurs, then problem will appear. The answer of Mr. Anurag Gupta is the more appropriate than us (I think).

Solution 1

Exa:
insert into Table1 (Column1,Column2) Values (Textbox1.Text,Textbox1.Text);

Now Column1 & Column2 Data Would be same.

your identity seed column seed must be set to one by default. So before inserting the data, read the last value of your identity column, increase it be one (or whatever your seed value is, and set it into second column.

Another, good way is writing a trigger for it which will automatically run whenever any insert is performed on the table, this trigger must update that particular column by the identity column value.

You can try any of these, both will work fine.
