HELLO ALL!
Im in a bit of a pucker. I need to do something complex, but not really sure what the best aproach is. I need to do it w/ a combo of SQL and ASP.net/
VB.net -- I am thinking I can just do it in SQL. But here is my problem.
I have a table with Test Results in it that looks Something like this.
pk | Test_desc | Score | Date_completed
--------------------------------------------------
1 | Test A | 79 | 1/2/2003
2 | Test B | 76 | 1/2/2003
3 | Test C | 87 | 1/2/2003
4 | Test D | 90 | 1/2/2003
5 | Test A | 79 | 1/3/2003
6 | Test B | 44 | 1/3/2003
7 | Test C | 99 | 1/3/2003
8 | Test X | 100 | 1/3/2003
9 | Test Y | 77 | 1/4/2003
10 | Test Z | 78 | 1/4/2003
They want to compair test scores, so I need my Results to look like this:
Test_desc | 1/2/2003 | 1/3/2003 | 1/4/2003
----------------------------------------------------
Test A | 79 |79 |
Test B | 76 |44 |
Test C | 87 |99 |
Test D | 90 | |
Test X | | 100 |
Test Y | | | 77
Test Z | | | 78
My first thought is to create a temp tables, one for each date. However, I need it to be dynamic, because sometimes there could 3 dates, and sometimes there could be 15 or 67. Never really know. My thought is to some how do a group by and create a temp table for each date, and then do a join between the primary table (the first one I listed) with each of the subsidiary temp tables. Then only list the score column from my subsidiary temp tables. A temp table looking something like:
test_des | score
---------------------------
Test A | 79
Test B | 76
Test C | 87
Test D | 90
I don't know how to create a Dynamic temp table based on a group by, OR if this is even the best approach???? -- HELP PLEASE!!, even thoughts or bits and pieces would be greatly appreciated.
