Question

I have the following table

    ID    p_name     p_value
   ----   ------     --------------
    1      name       index.htm
    1      path       c:\web\site1
    1      size       400
    1      date       2011-03-12
    1      note       'test site'
    2      name       login.htm
    2      path       c:\web\site1
    2      size       500
    ...    ...        ...
    ...    ...        ...

I need to make it look like this

    ID   Name         Path
   ---   ----------   -------------
    1     index.htm    c:\web\site1
    2     login.htm    c:\web\site1
    ...   ...          ...

I was reading few other posts, but I could not figure out how to apply it on my example!
I just need mainly the “Name” and the “Path” and I may add others when needed!

Answer 1

Simplest way is to case it out since it seems you have a finite number of p_names for a given ID.

Attempt 2 – revised

Select ID, T1.P_Name as Name, T2.P_value as Path
FROM YourTableName T1
INNER JOIN yourTableName T2 
  ON T1.ID = T2.ID 
  and T1.P_Name = 'name' 
  and T2.P_name = 'path'

Attempt 1 – Blunder

SELECT Id,
CASE p_name when 'name' THEN P_value end as Name,
CASE p_name when 'path' THEN p_value end as Path
FROM yourTableNameHere
