-WHAT ARE THE TABLES AND THOSE ROWS-
TABLE 1 - "ITEMS"
-------------------------------------------------------------------------------
ID_Item(PK)ItemName
1Bicycle-Ultra
2Barbie And Ken
3MotorBike
....
TABLE 2 - "CustomFieldsValues"
-------------------------------------------------------------------------------
ID_Item(FK)ID_CFvalue(PK)ID_CFName(FK)CFValue(nVarChar)
111Carbon & Titan

...... ..
TABLE 3 - "CustomFieldsNames"
-------------------------------------------------------------------------------
ID_CFName(PK)CFName(nVarChar)

I'm sure someone smarter then me may come along with a good recommendation, but I think what your asking for is to pivot the table. Check this article out and see if it helps any

PIVOT clause

Thanks, I will check on nexts hours ..

But as far as i search last 4 hours some related on inet, the PIVOT / UNPIVOT related sources was seems difficult to understand by myself.

Read the article at the URL in my signature line... you'll get a lot better help...

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Thanks to all.

Finally i found the solutions, on a thirds urls that i found.

Thanks to GrassHopper and the other one. The GrassH Url's serves me a trick to found more info and other urls, on witch i can make the solution work.

The technique used is PIVOT but without Aggregate !!

It's a hurt that nobody's post code, but as i mentioned above, finally i accomplish this task (1/*n jj)
