  Hi,

  I assume you know about https://www.w3schools.com/SQL/sql_insert_into_select.asp ? If you have a problem because of your condition we would need to know about it so that one can see it it could still be done using that or few SQL statements.

  At some point if you have really no way around looping on each and every row, cursors are intended for doing that.

  Post your table structure  and sample data and your expected result. You may think in loop but you should implement set based solution in database. Post your sample and you will get help from there. Thanks.

  I would think you would want to do the following:

  INSERT INTO #temp2 (column1, column2, column3, ...)
  SELECT column1, column2, column3, ...
  FROM #temp1
  WHERE condition;

  Hope this helps you.
