View 6 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')
Is it possible to execute a command like this?
select * from tbl where col1=somefunction(@param1)
or will the parameter throw off the function? I have been unsuccessful in getting the command to work so far.
Please let me know if this needs any further explanation
I wrote a loop that posted an accrued principal cycle to a listbox for a period of 10 years (10 loop cycles). The problem is: not only does the amount of the principal reconfigure for each loop cycle, but it does not truncate into a two decimal place holder as it should. I would like to use the ("F2") but I am not sure where to put it within the code. Here is what I have for the Calculate button event handler.

Can we use Content place holder within the head section of a master page?
For example :
<head runat="server">
<title>Untitled Page</title>
<asp:ContentPlaceHolder id="ContentPlaceHolder2" runat="server">

<link href="StyleSheet.css" rel="stylesheet" type="text/css" />
</head>

View 2 RepliesLike I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.

It appears that I'm just not connecting with my MySql Db. Any ideas??? I'm certain that I' m using the correct information in the string.
so i've been looking around for days trying to fix this but can't seem to find a right solution. I'm trying to make a login/registration system. Right now, It reads things from my database FINE but it doesn't add the information to my database. It returns "Object reference not set to an instant of an object.".

I'm in the process of switching my application from MSSQL to MYSQL. When I was using MSSQL, I retrieved the last auto increment value via
Private Sub dsImpoundInformation_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles dsImpoundInformation.Inserted
_impoundId = e.Command.Parameters("impoundId").Value
End Sub
[Code]...
ultimately, I'm just trying to get the last auto increment value but there are other sections of my code in other applications that I plan on switching to MYSQL that depend on output parameters. I have't yet explored using stored procedures but at this time I would like to get this to work in a similar fashion to how I had it with MSSQL.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ':=Reviewed_By) Reviewed_By,Stage,sum(Review_Status='Int_Approved') as Approved,s' at line 1
