I try to remove the duplicate rows by select a first row from every group.
For Example
PK Col1 Col2
1 A B
2 A B
3 C C
4 C C
I want a return:
PK Col1 Col2
1 A B
3 C C
I tried following code but it didn't work:
DataTable dt = GetSampleDataTable(); //Get the table above.
dt = dt.Select("SELECT MIN(PK), Col1, Col2 GROUP BY Col1, Col2);
