Goodday,
How can I do a select on a dataset table with the "Right" function on a string ?
Problem now is that the "Right" function is not usable in the rowfilter or a .Select()

Example :
ds.Tables("Overview").DefaultView.RowFilter = "right([Dates],4 = " & dat_year

The table in the dataset ds contains the column Dates in which text is stored like :
"01.01.2005 - 01.02.2005"   and I would like to do a select on the last 4 char.

HI,
instead of checking the year part check the date from 01/01/date_year till 31/01/date_year
startDate as string
endDate as string
startDate = "01/01/" & dat_year
endDate = "31/01/" & dat_year
ds.Tables("Overview").DefaultView.RowFilter = "[Dates] >= " & startDate & " and [Dates] <= " & endDate

I hope that this helps you


Kind Regards
Venki

try:

1) ds.Tables("Overview").DefaultView.RowFilter = "Date>=#01-01" & Yr & "# AND Date<#01-01" & Yr +1 & "#")

2) ds.RowFilter = "Convert(Date,'System.DateTime') =" & Yr

3) ds.Tables("Overview").DefaultView.RowFilter = "Year(Date) = " & Yr

sorry:

don't forget the # in 1

and 2) should be:

ds.RowFilter = "(Convert(Date,'System.DateTime')).Year =" & Yr
