Sql Convert String To Datetime?

Aug 3, 2009

I have the following sql select statement in my code:

Code:

sql = "SELECT * "
sql &= "FROM Trn_DC_All "
sql &= " WHERE (Content LIKE '% PAGE%') AND Convert(datetime,Substring(Right(Trn_DC_All.Content,21),2,10),7) >= " &

[code]....

Basically, for the substring in the select satement,the datatype is string. By the way, the strFromDate and strToDate datatype are string also.Actually I would like to select the data from database whereby the Substring(Right(Trn_DC_All.Content,21),2,10) is larger than strFromDate but smaller than strToDate.The dataformat in the database is "Feb 01,09" and the strFromDate,strToDate format is "20/07/2009".What should I change in my select statement so that it can retrieve the data?

How To Convert String Into DateTime Format

Jun 8, 2010

I wish to convert my string in format dd/mm/yyyy hh:mm:ss to a DateTime of the same format.
Dim ukCulture As System.Globalization.CultureInfo = New System.Globalization.CultureInfo("en-GB")
Dim myDateTime As DateTime
myDateTime = DateTime.ParseExact("18/05/2010 23:42:10, "dd/MM/yyyy HH:mm:ss", ukCulture)
When I step through this code the variable myDateTime is 05/18/2010 23:42:10 it appears that the dd/mm is the wrong way around and I cant work out how to correct this.

Match A Certain DateTime Value With Current System DateTime

May 7, 2010

I'm trying to match a certain DateTime value with the current system DateTime. I have a timer and a label on a form. Timer interval is set to 1000. When the form loads, the timer starts ticking. As soon as the current DateTime matches the value of the variable, it shows a message in the label. When I'm writing the following code, the values don't match even if the current system DateTime is equal to the variable. Label1 isn't showing 'Times Matched':[code]The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

Why is it so? The default format of 'Now' is the same as I have stored in dtmVar variable. So there's no question of format mismatch. Does that mean 'Now' is not actually a DateTime property? Provided, my O.S. is Windows Vista Ultimate and all date/time settings are set to default.

C# - Compare Datetime.Now With A Datetime Variable

Dec 27, 2010

I try to compare Datetime.Now with a Datetime variable I set, using the Datetime.CompareTo() method. I use a timer to compare these every second and display the result, but as the current time approaches the time I set, the result changes from 1 to -1, but never 0, which means these two are never equal. I'm suspecting the Datetime structure contains milliseconds?
