Question

How can I insert values into table variable from another table by adding a column that counts original records. e.g.

 Value              Number    Value
----------  --->    ----------------
 56                 1         56
 78                 2         78
 90                 3         90

However, I cannot use an IDENTITY(1,1) to automatically generate counter values because I want to explicitly insert values into Number column. May be I should use CTE?

select row_number() over (order by (select 0)) as number,value from @tablevariable
