将PDO结果传递到另一个临时表或插入到临时表

Question

Hello ,

             $sql = "select col1 , col2 from table where id=2"; // sometimes query larger
             $q = $conn->prepare($sql);
             $q->execute(array_values($v));
              $q->setFetchMode(PDO::FETCH_BOTH);
               while($r = $q->fetch())

               {                
                     echo " $r[$i]";

                }

Code is Working Fine.

Now i want To save Query Result to Another Temporary Table. i Dont know no. of columns generated in Query result. Each time Query is different so columns and data is different. So How store that Query result to another table.

Answer 1

You could let MySQL do that work for you, eg via

CREATE TEMPORARY TABLE new_tbl SELECT * FROM orig_tbl WHERE ...
