Insert statement with cursor

In a table there are like 113 columns. and there are two default records in the table, one is for unknown and another is for inapplicable. So, each column has its own default value to represent unknown and inapplicable.

I dont wanna write regular insert statement to get those two records.

so, I tried to insert each column using a cursor.

Got the names of columns for that table from information_schema.columns and tried to insert values from exact table in another location using "insert into select" statement, but the name of the columns that we get from information_schema

Declare @col_name varchar(50)

declare my_cur CURSOR for
  select  column_name  from information_schema.columns 
  where table_name = 'tabl' and table_catalog = 'db'
  and table_schema = 'dbo'


  Fetch next from my_cur
  into @col_name

  while @@FETCH_STATUS  = 0
  BEGIN

   Insert into db.dbo.tabl (***@col_name***)
   select ***@col_name*** from openrowset('sqlncli', 'server=my_server;           trusted_connection=yes;', db.dbo.tabl) 



  fetch next from my_cur into @col_name
  end

close my_cur
deallocate my_cur
go

But, I did not realize that @col_name would be treated as string, rather than object (column)

Is there any work around for this case or any alternative solution.

Solution

You will have to generate the INSERT statement as dynamic SQL and then execute it

Declare @InsertStatement VarChar (Max)

SET @InsertStatement = ''

SET @InsertStatement = @InsertStatement + ' Insert into db.dbo.tabl (' + @col_name + ') '
SET @InsertStatement = @InsertStatement + ' select ' + @col_name + ' from openrowset(''sqlncli'', ''server=my_server'';  '

Exec Sp_SQLExec @InsertStatement
