I have a table based on a warehouse inventory. Each record represents an item in the inventory and contains an Item #, ROW, COLUMN AND LEVEL. What I need to do is return a value for each unique row with the high and low values for column and level. See sample data below: (sorry about the lack of spacing. I don't know how to stop UT from removing spaces)


Item Row Column Level

123 1 02 A
234 2 05 D
345 3 01 A
456 1 01 F
567 2 03 A
678 3 07 H
789 1 04 C
890 2 01 L
901 3 09 F


This should return

row clow chigh llow lhigh
1 01 04 A F
2 01 05 A L
3 01 09 A H
Thanks for any help
