Use this:

C#

string commandstring = "SELECT MAX(ADX) FROM @out_table WHERE [Date] between @strt_date  AND @end_date";
            OleDbCommand cmd = new OleDbCommand(commandstring, con);
            cmd.Parameters.AddWithValue("@out_table", out_table);
            cmd.Parameters.AddWithValue("@strt_date", dt_start);
            cmd.Parameters.AddWithValue("@end_date", dt_end);
            string val= (string)cmd.ExecuteScalar();

Date is a reserved name then:
It's better to use [Date]
And do not use parenthesis

Ensure that Date type in your database is "DateTime" and the type of dt_start and dt_end is "Date"
If You tried the code (In my Solution) and the types are ok, then the problem is not the code. It'is from another part of your application.

Solution 1

Take out the final set of brackets:

C#

string commandstring = "SELECT MAX(ADX) FROM @out_table WHERE Date (between @strt_date AND @end_date)";

Becomes:

C#

string commandstring = "SELECT MAX(ADX) FROM @out_table WHERE Date BETWEEN @strt_date AND @end_date";
