While reading data from xls file, using oldedb as follows with no problem
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [" + fileID + "]", oledbConn);
DataSet ds = new DataSet();
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
da.Fill(ds);
But I want to extend the select statement to only select rows of a certain column that is not null WHERE ... IS NOT NULL, what is that ... suppose to be?
If you use the option HDR=YES
in your connection string
then use the column title in the WHERE
clause to specify the column.
If not, then use F1...FN
to specify the column.
Select query for HDR=NO
(and first column):
SELECT * FROM [" + fileID + "] WHERE [F1] IS NOT NULL
Select query for HDR=YES
:
SELECT * FROM [" + fileID + "] WHERE [YourColumnTitle] IS NOT NULL
