i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net. I've made many attempts however i'm still getting the error that i have an error in my SQL Syntax. The format that the DateTime in Vb.net is 6/21/2011 12:46:25 PM. I need to convert that to the MySQL DateTime Format which is 2011-06-21 12:46:25 and also is running on a 24 hour clock. I've searched many forums and haven't found a conclusive solution yet. Below is the code i have so far, with attempting any DateTime Conversion.

View 1 RepliesI am having trouble with a mySQL query with the .NET connector. When I create the query, it automatically creates my parameters as objects. I usually change the type to the correct type, which in this case is Date, but I get different results passing in the parameter as a date.When I do "Preview Query" as an object, I get the correct results, but bad results as a Date. I would just leave them as objects, but it errors out when I try to pass a date in.Here's the part of my query that I'm having trouble with:
(Tickets.Resolved >= str_to_date(@startDate, '%m/%d/%Y')) AND (Tickets.Resolved <= str_to_date(@endDate, '%m/%d/%Y')) AND
(Tickets.Status = 'resolved' OR
Tickets.Status = 'rejected')

I am trying to display the day pulled from a datetimepicker menu. I have no problem displaying the day in the textbox using a button and this [code]...
The problem I am having is I don't want to have to press a button. I just want the day to always be displayed. For example, If the default value is now() from the datetimepicker, I want the textbox to display only the day portion (Sat) but not have to press any button to activate it. When the user changes the datetimepicker to tomorrow or whenever, as soon as the new date has been selected, I would like the textbox to display the new day value for the date selected.
