VS 2008 Sql Convert Varchar To Datetime?
Jul 8, 2009
I got the dates stored as varchar(100). I need to get them sorted when I use these records but I can't now because they are not stored as datetime. Is there any other way to sort dates or if somebody know would I loose my data if I would try to convert the column from varchar(100) to datetime now as it holds my dates or maybe it would convert ok?

Error converting data type varchar to datetime.rtfI am trying to learn ASP.NET using ASP.NET 1.1 with SQL Server 2000 for the database. I have created a Stored Procedure in SQL Server 2000 and the procedure to execute the Stored Procedure is in ASP.NET 1.1. The problem is that when I try to save a record, the date field returns the above error. I have ried to use the several solutions on the web without getting one to solve the problem.I am attaching the Stored Procedure as well as the ASP.NET code for some advice. I am also attached a word document containing the two procedures.

Im having an issue with a Stored Procedure I have written,I can call it in management studio and it works fine, yet calling it from my codebehind gives this error The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. when i call da.Fill(dt)What is really puzzling me here is that I dont actually convert anything from varchar to datetime, the most I do with the date variables is format them into a different datetime format.
My VB.Net code
Private Function dbGetEvents(ByVal start As DateTime, ByVal days As Integer) As DataTable
Dim dt As New DataTable()[code].....
I cant see where this error could be coming from, having tested running it in SQL management studio without error I am pretty sure the error is in the VB.My first thought was that maybe the parameter I am passing in the @start / @end values arent being recognised as DateTime so I tried adding the parameters like:
Dim p As New SqlParameter
p.SqlDbType = SqlDbType.DateTime
p.ParameterName = "@start"[code]....

I want to insert only date into the db but in the following statement that I've wrote which inserts the date in mm-dd-yyyy hh:mm:ss format.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & TimeLabel.Text.Trim() & "')" & "Update Blotter Set Name = UPPER(Name)"
I have tried the following code, however it didn't work.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & (CDate(TimeLabel.Text.Trim().ToString("MM/dd/yyyy")))& "')" & "Update Blotter Set Name = UPPER(Name)"
[code]
I also tried format the TimeLabel as below but still didn't work. [code] TimeLabel.Text = CDate(DateTime.Now).ToString("MM/dd/yyy")

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?

I am very surprised to see the output of the function with the given value ,DateTime.Parse("08/19/2011 11:32"). I am using VS2008. Always it returns 08/19/2011 11:32 AM. and if the pass value would be 08/19/2011 14:23 then the output value would be 08/19/2011 02:23 PM. But sometimes it is returning 08/19/2011 11:32 PM for DateTime.Parse("08/19/2011 11:32"). Why?

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.
Imports MySql.Data.MySqlClient
Public Class FinalFailedPinNumberAttempt
Dim connectionstring As String = "Server=localhost;user id=root;Password=;database=mylaundrycompany"
Dim SQLConnection As MySqlConnection = New MySqlConnection
