Is the following valid syntax? Thanks for your help!
IF (SELECT chargeID FROM inserted = 0) BEGIN
END
OR, should I be doing something like this:
DECLARE @thisChargeID as int
SET @thisChargeID = (SELECT chargeID FROM inserted)
IF (@thisChargeID = 0) BEGIN
END

View 1 Replies View Relatedim 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.

Hi,
I'm trying to install MSDE SP3 which I downloaded from MS at http://www.asp.net/msde/.
Following the instructions as best I can I unzipped the file into a Folder now called MSDE located on C: I then went to a command prompt and typed in the command given to start the install:
setup SAPWD=testsite SecurityMode=SQL
Hit enter and the installer started up and ran for a few secs and then came back with
The Instance named specified is invalid
There was no mention of including an instance name or the format for it.
Suggestions please?
Also, if I want to completly uninstall MSDE if I need to how would I do it?
Thanks,
Bob
Can't seem to find why I'm getting this error: Specified cast is not valid.
Ok, using a stored procedure for SQL Server 2000 and here is the main part of it:
SELECT id, rank, firstName, lastName, service, status, createdTime FROM accessRequest WHERE lastName LIKE @tLastName AND firstName LIKE @tFirstName
And the C# code behind from the class file:
SqlDataReader spResults;
conn.Open();
spResults = command.ExecuteReader();
while( spResults.Read() )
{
AccessRequestSearch request = new AccessRequestSearch( (int)spResults.GetInt32( 0 ), spResults.GetString( 2 ), spResults.GetString( 3 ), spResults.GetString( 1 ), spResults.GetString( 4 ), spResults.GetString( 5 ), Convert.ToDateTime(spResults.GetString( 6 )));
searchResults.Add( request ); // Add to Array List
}
spResults.Close();
The part in red is where I think it's happening because that is what I just added to the request. createdTime in the table is set as DateTime.
Can anyone see what I am missing here?
More info is available if needed.
Thanks,

I have a question regarding the backup to use in case of consistency errors.
I'm backing up my dbs daily and logs hourly with 'verify the integrity of the backup when completed' checked. Today I found out one of my tables has 1 page id error (dbcc checkdb message from yesterday), I'm wondering if I can use yesterday's full backup even if it's done after the dbcc, that way I don't have to apply a lot less log backups. In other words, does or does not the full backup inherit the corruption if it is done after consistency errors and the backup passes the integrity verification.
Thanks,

I'm having this really strange issue with mirroring.
I've followed the instructions on http://msdn2.microsoft.com/en-us/library/ms191140.aspx to the letter, leaving out the witness server part, as I don't have one.
All works OK, but when activating the mirroring on the principal server I get the usual error 1418 error. I fired up SQL Server Profiler to see what was happening, and the following error emerged.
Connection handshake failed. The certificate used by the peer is invalid due to the following reason: Certificate not yet valid. State 104.

I've got a linked server setup to DB2, and some of the
date fields in the DB contain 1/1/0001 values.
I've got views created in SQL2000 against the DB2 linked server.
When I run a query against a particular table that contains multiple field of datetime type.
I get the below error
Server: Msg 8114, Level 16, State 8, Line 1
Error converting data type DBTYPE_DBTIMESTAMP to datetime.
This only happens when I include in the select the field that contains 1/1/0001 values.
I assume since valid dates ranges in SQL are from
January 1, 1753 through December 31, 9999, this would be
what's causing this.
I tried to covert in the select but that failed as well. The only thing that I've been able to do, is to use a DTS to pull the data from the DB2 to a local SQL2000 table, with that fields type set as varchar. This works.
Using a DTS to pull the data to a local table in production isn't a viable workaround, since this table contains 1.8 million rows.
How is DTS converting this field, when convert fails in the select?
How do I get around this?
Thanks

Hello Everybody
I'm getting a strange error.
I have created a Datatable and in this table I have multiple Columns.
I have given them all a name and now when I want to put data in the DataTable I get a error.
All goes well until I try to Update the Datatable
Code Snippet
DataRow DrWb = ppcDbDataSet.Item.NewRow();
DrWerkbon["ItemNummer"] = Defines.mcItem.miItemNr;
DrWerkbon["WorkerNummer"] = Defines.mcWorker.msWorkerNr;
Defines.mcItem.msWorkerNr = Defines.mcWorker.msWorkerNr;
DrWerkbon["CustomNummer"] = Defines.mcCustom.msCustomNr;
Defines.mcItem.msCustomNr = Defines.mcCustom.msCustomNr;
DrWerkbon["WbRedenBezoek"] = edRedenBezoek.Text;
Defines.mcItem.msReason = DrWb["WbReason"].ToString();
ppcDbDataSet.Item.Rows.Add(DrWerkbon);
ItemTableAdapter.Update(DrWb);
ppsDbDataSet.Clear();
ItemTableAdapter.Fill(ppcDbDataSet.Item);
At the ItemTableAdapter.Update(DrWb) it gives the error:
SqlCeException was unhandled
The Column name is not valid. [ Node name (if any) = , Column name = WbReason ]
I don't understand why it is giving this error because the name of the column realy is WbReason
Does anybody know what to do about this??
Kind regards

Hi,
I'm trying to set up a data-driven subscription and having problems with parameters. On the Report Parameter Values screen of the Create Data-Driven Subscription function I have set a parameter TimesheetPeriodEnd to "Specify a static value" and checked the NULL box. In the report the parameter is type string and allows nulls. When I try to run the subscription the reports are not sent and the error log contains the following message:
ReportingServicesService!library!f!10/05/2007-09:31:08:: Status: Failure sending mail: Default value or value provided for the report parameter 'TimesheetPeriodEnd' is not a valid value.
ReportingServicesService!notification!f!10/05/2007-09:31:08:: Notification 0ae544df-4b1b-4a46-b7ab-cdefdca201be completed. Success: False, Status: Failure sending mail: Default value or value provided for the report parameter 'TimesheetPeriodEnd' is not a valid value., DeliveryExtension: Report Server Email, Report: Timesheet, Attempt 0
I am also setting other parameters for this subscription in the same way and not getting errors.
Any ideas? Previously I have had problems passing null values to parameters from the subscription query "Get value from database" from SELECT NULL AS ParameterName (this function just doesn't seem to work in SSRS). But I'm surprised I can't even seem to get this working with the default settings.

I pass in a variable SourceServer to my package via the command line. In our production environment we are seeing:
The expression "@[User::SourceServer]" on property "ServerName" cannot be evaluated. Modify the expression to be valid
Is this just because the evaluation takes place prior to the command line parameters being set and I need to turn off validation?

I am deploying an rdl that is being deployed in a server.But i am encountering a problem regarding the valid values of the parameter.My parameters have dependencies,and one of my parameter comes out with two dependencies.
Scenario :
User needs to input his userID to access Book A.
Book B needs Book A because the output will be depending on the its content.
And Book C depend on Book B.
Problem:
when deploying, only Book A will have the initial value.The dependency in Book B is only one,which is fine.It shows its valid values. But how about for Book C which have 2 dependencies? Because it doesnt show it's valid values..
The configuration file name "C:......XMLSSIS2005_ConStr.dtsConfig" is not valid. Check the configuration file name.
The path is correct but we got this error. Please help us.

Hi there guys!!
I am having an issue with generating a table for an report on the fly. I have been referring to the example on www.gotreportviewer.com and their example works fine but when i attempt to do my own version (by adding the table, I get the following error:
The report definition is not valid. Details: The element 'TableColumns' in namespace 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition' has incomplete content.
List of possible elements expected: 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition:TableColumn'.
From my understanding 'TableColumns' was not expected even though i reference it correctly in my code and I it is defined in the ReportDefinition. It also causes no problems for the example from the above website.
Can anyone help with this problem?
Thanks a million!
Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

aRow["OldValue"] = dRow[column.Ordinal].ToString();
aRow["NewValue"] = null;
aRow["ChangeDateTime"] = DateTime.Now.ToString();
aRow["ChangedBy"] = User;
AuditTable.Rows.InsertAt(aRow, 0);//Insert the Entry
}
break;
default:
//Do Nothing
break;
}
AuditAdapter.Update(AuditTable);//Write all Audit Entries back to AuditTable
conn.Close(); //Close the Connection
}
}
//Helper function that takes a Table of the Primary Key Column Names and the modified rows Values
//and builds a string of the form "<PKColumn1Name=Value1>,PKColumn2Name=Value2>,......"
public static string PKStringBuilder(DataTable primaryKeysTable, DataRow valuesDataRow)
{
string temp = String.Empty;
foreach (DataRow kColumn in primaryKeysTable.Rows)//for all Primary Keys of the Table that is being changed
{
temp = String.Concat(temp, String.Concat("<", kColumn[0].ToString(), "=", valuesDataRow[kColumn[0].ToString)].ToString(), ">,"));
}
return temp;
}
}
The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.
Comments and Suggestion will be much appreciated.
