  table1

  id   value

  2    20

  3    30

  4    40

  5    50

  6    60

  7    null

  the above table has to be inserted into another table2 with following fashion

  i,e: it has to insert the value corresponding to 2 into col1 when id =2 ,col2 when id=3  and so on.  note: insert empty when null is the value

   

  table2

  col1      col2    col3    col4    col5     col6

  20          30     40      50         60      empty

  What have you tried so far? Have you had a look at PIVOT, or (what many prefer), using a Cross Tab?

  Excuse my typos and sometimes awful grammar. My fingers work faster than my brain does.

  What would you insert if there are multiple source rows with the same Id? For example

  id   value

  2    20

  2    30

  Would this require two inserts of 20 and 30, or a single insert of 50 (SUM), 25 (AVG), 20 (MIN) ... or some other aggregate?

  If the answer to your question can be found with a brief Google search, please perform the search yourself, rather than expecting one of the SSC members to do it for you.
