Question

I have a simple SqlCommand in which I want to return all records within a specified DateTime range. (both Date and Time are involved)

var dataReader = new SqlCommand(
    @"Select RecordID from RecordTable
    where RecordTable.WorkingDT between '"+ _startDt +"' and '"+ _endDt +"'",
    _sqlConnection).ExecuteReader();

how do I have to set the values for _startDt and _endDt?

Answer 1

You can try this:

var dataReader = new SqlCommand(
    @"Select RecordID from RecordTable
    where RecordTable.WorkingDT between '"+ _startDt.ToString("yyyy-MM-dd HH:mm:ss") +"' and '"+ _endDt.ToString("yyyy-MM-dd HH:mm:ss") +"'",
    _sqlConnection).ExecuteReader();

Where _startDt and _endDt are type of DateTime.
