Alternately, if you're using a product that supports the "TOP" keyword, and you have the ToQty column indexed in assending order, you could use SELECT TOP 1 Rate, ToQty FROM MyRateTable WHERE @qty <= ToQty ORDER BY ToQty and just ignore the ToQty in the return. This will guarantee good performance as the query will recognize the ORDER BY clause and use the existing index for the select. Lastly, if your table really is as simple as the data you have used for your example, a mathematical formula would be better. int getRate( int myQty ) { if( myQty = 0 ) return 100; else return (1+((myQty-1)/5))*100; } which could also be converted to SQL if you wanted. Hope this helps. Re: Urgent Test27030730-Mar-07 18:40 Test270307 30-Mar-07 18:40  thank u.it works.

How can I path all rows on the table to change a field .. eg Serial .. like that For i=0 to datatabale.Rows.Count-1<br /> .<br /> .<br /> next i but I want to use any method instead of "Update table set ....." By using Datatable can I do it "path on all rows to change certain field" by usting the index of the row : DataTable.Rows(i)("Serial") .. I'm sorry , that my english isn't good .. but I hope if any one understand what I mean .. and thanks for my best Forum jooooo Re: Change a field on all tabel ,, row by row ? kubben30-Mar-07 2:19 kubben 30-Mar-07 2:19  You can use a cursor to do something similar to a for loop, but it is very slow compared to a single update statement. I would suggest you think seriously about using a single update statement instead. Ben Re: Change a field on all tabel ,, row by row ? kindman_nb30-Mar-07 2:32 kindman_nb 30-Mar-07 2:32  Thanks Ben.. but I think on that method : I want to gove some records a serial >> like 1,2,3 .... and I can't make that fields Identifier because the serial will be repeated again with another invoice ... then I'd like to path all selected feilds and give every one it's serial ... from the first to the end .. then if I user Update statement .. I can't know which record will take No 1 and which will take No 3 ... I want by the for .. next .. to give all selected row it's serial .. I know that is strange and there's another method to solve that .. but on my project now , I need this method ... again .. I hope if any one understand what I mean jooooo Re: Change a field on all tabel ,, row by row ? kubben30-Mar-07 2:36 kubben 30-Mar-07 2:36  Well, perhaps you should still look at using an update statement, but then using a scalar function. You could pass in some value you would help the function know what serial number to return. Just a thought.
