This is a Subject Expression I put in my Mail component in my SSIS 2005 package but it's not liking the StartTime concatenation. I tried other ways but can't get it to allow this:
"Process Started by : " + @[System::UserName] + (DT_DATE) @[System::StartTime]
The data types "DT_WSTR" and "DT_DATE" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.
Attempt to set the result type of binary operation ""Process Started by : " + @[System::UserName] + (DT_DATE)@[System::StartTime]" failed with error code 0xC0047080.
I tried to use CAST() but not sure if that's allowed or the syntax for it specifically in SSIS 2005
I have been trying to store some start times, System::StartTime, System::EventHandlerStartTime and the likes to get exact running times for packages and tasks. What I am beginning to believe is that the maximum resolution of these times are seconds. It could be an incredible coincidence, but when I store the following string in the database OnPreExecute: (DT_WSTR, 30)@[System::EventHandlerStartTime] + " " + (DT_WSTR, 30)GETDATE() I will get results like: 2006-01-10 10:58:38 2006-01-10 10:58:38.377000000. There are never any milliseconds shown for the EventHandlerStartTime. I am going use GETDATE() for now as a workaround, but I would prefer to use the exact start time. Any suggestions?
I am trying to get the System::StartTime into a table, but I get this error in my expression builder saying "Cannot convert 'System.DateTime' to 'System.String'
I have tried (DT_TEXT, 1252) @[System::StartTime] but I get the following
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (Microsoft.DataTransformationServices.Controls)
I also tried (DT_STR, 23, 1252) @[System::StartTime] and I get the following error
The expression " (DT_STR, 23, 1252) @[System::StartTime]" has a result type of "DT_STR", which cannot be converted to a supported type.

Hi, I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ? Thanks a lot in advance.

The user is prompted to specify a starttime like 02 and a endtime 04. The user for example wants to search all events between 2 am and 10 am regardless of the date. I use the following SQL ti filter: Where (DATEPART(hour, Event.EventDateTime) BETWEEN @StartHour AND @EndHour)
This works fine as long starhour is smaller than endhour. When i want to filter Events beteween 23 (11 pm.) and 02 (2 am) i get no results. I have to make a search possible for a time span that is over midnight.

Ok guys, I am trying to install Sql server 2005 on Vista but I am still stuck with this warning message in the System Configuration Check during Sql server 2K5 installation :
SQL Server Edition Operating System Compatibility (Warning) Messages * SQL Server Edition Operating System Compatibility
* Some components of this edition of SQL Server are not supported on this operating system. For details, see 'Hardware and Software Requirements for Installing SQL Server 2005' in Microsoft SQL Server Books Online.
Now, I know I need to install SP2 but how the hell I am going to install SP2 if Sql server 2005 doesn't install any of the components including Sql server Database services, Analysus services, Reporting integration services( only the workstation component is available for installation)?
Any work around for this issue?
P.S.: I didn't install VS.NET 2005 yet, can this solve the problem?

Found a similar problem in a different thread, but couldn't find any solution. I was wondering if there is an open case for this issue?
Hi,I have a few things on my databases which seem to be neither true systemobjects or user objects - notably a table called 'dtproperties' (createdby Enterprise manager as I understand, relating to relationship graphingor something) and some stored procs begining with "dt_" (some kind ofsource control stuff, possible visual studio related). These show up whenI use"exec sp_help 'databaseName'"but not in Ent. Mgr. or in Query Analyzer's object browser, and also notin a third party tool I use called AdeptSQL. I am wondering how thosetools know to differentiate between these types of quasi-system objects,and my real user data. (This is for the purpose of a customized schemagenerator I am writing). I'd prefer to determine this info with systemstored procs (ie sp_help, sp_helptex, sp_...etc) but will dip into thesystem tables if needed.Thanks,Dave

im doing a sum on a table and it either returns a number in decimal format or 'null' . The problem is when it returns null i want it to just make the text say '0.00'. So i did a test on the object that if it returns NULL just print '0.00' but if it is not null it tells me that there is a number there and i want to store that as a decimal and print it out. But i get an error for a type cast when im not it should not even be going to that part of the code. In the code below the first executescaler will return null so it should just go straight to the else. But it gives me the type cast error in the if that shouldnt be seen.

I am pretty new to SQL for SQL Server 2005. In a view I have a column CAST(Field1 as int). Field1 is a varchar.All works well except when the data is not numeric such as a '?' or '*'.How can I get around this, with a case statement, coalese?I only want to perform the CAST on valid numeric values.The valid values in the varchar field are blank, null,'0','1','2','3','4','5','?','*' and maybe othersThanks
If I run the following query in SQL Server Management Studio it returns the correct results: (Searching the table for the field "SpecimenID (an INT)" against the data entered (a Text Field - "7575-01") from the submitted form.

Can someone please explain what I am missing here.... MySQL = "SELECT * FROM ClinicalSpecimen WHERE SpecimenID = CAST(('" & AccessionPresent & "') AS VARCHAR(50))" *"AccessionPresent" is the value of the text field retrieved from the form. I guess what I am really asking is how can I search for an INT value in a table using a VARCHAR Field. Thank you for any or all assistance !!!
Hi over there,I hope this question is not too simple, but I didn't manage to figure out why...I would need an explanation for following issue:I'm reading data from a database (MSSQL) and it the column "PersonBirthday" is DBNull.I wanted to prevent the error (Textbox.Text = DBNull) with an IIF. The thing is I get thistypecast exception:"Conversion from type 'DBNull' to type 'Date' is not valid." This code is NOT working, why? txtPersonBirthday.Text = IIf(IsDBNull(.Item("PersonBirthday")) = True, String.Empty, CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd")) When I'm using this code, which is for me obviously the same, just with an if-block it works,and I want to know why - please explain. If IsDBNull(.Item("PersonBirthday")) Then txtPersonBirthday.Text = String.Empty Else txtPersonBirthday.Text = CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd") End IfThanks in advance,cheers,uquandux If IsDBNull(.Item("PersonBirthday")) Then txtPersonBirthday.Text = String.Empty Else txtPersonBirthday.Text = CDate(.Item("PersonBirthday")).ToString("yyyy-MM-dd") End If
