Hello Experts,

I am banging my head on what seems to be a simple query.  I need to massage the data into a different presentation.  I need to take the values of the input table and create column names for the output table.

Here's what the input table looks like:
      
ID      TYPE      Value
45      invoice      12345
45      check      555444
45      date              12/5/2013
46      invoice      987654
46      check      555666
46      date              12/3/2013

i need the output to look like this:
output                  
ID      invoice      check      date
45      12345      555444      12/5/2013
46      987654      555666      12/3/2013

thanks!!!

You need to pivot the data, sorry don't have time to do it, but here is a reference http://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx

This is how you do it with PIVOT:
SELECT ID, 
[invoice], [check], [date]
FROM
(SELECT ID, Type, Value 
    FROM Table1) AS SourceTable
PIVOT
(
MAX(Value)
FOR Type IN ([invoice], [check], [date])
) AS PivotTable;

If there are a limited number of values for type  (e.g. 3 as in your example) -
select id,
max(case when type = 'invoice' then value end) as invoice,
max(case when type = 'check' then value end) as check_rcvd,
max(case when type = 'date' then value end) as somedate
from input_table
group by id;
