GUID Param.dbtype In Designer Generated Code

Apr 2, 2008

When using a typed dataset in VS 2005 with SqlCe 3.1, it conitinues to make the param.dbtype for the GUID to be an 'object'. When as far as I can tell it needs to be a 'Guid' dbtype. So each time I modify the typed dataset I go in and manually change the various bugs and things work fine. My question is whether or not anyone knows a better work around for this after finding themselves in this situation.

I've attached a code sample of the erroneous designer code, and highlighted the line that should instead be set to DbType.Guid.




Code Snippet
global::System.Data.SqlServerCe.SqlCeParameter param = new global::System.Data.SqlServerCe.SqlCeParameter();
param.ParameterName = "@ProjectQuoteGUID";
param.DbType = global::System.Data.DbType.Object;
param.Size = 16;
param.IsNullable = true;
param.SourceColumn = "ProjectQuoteGUID";
this._commandCollection[1].Parameters.Add(param);






Thanks

How To Use Both Auto Generated Id And A Guid In Database

Oct 22, 2006

I downloaded the AdventureWorks OLTP Schema and am trying to use some of the design concepts that are used in this example but I don€™t quite understand some things.

First there is a column named rowguid, at the moment I assume that this is a GUID. If this is wrong most likely my next question will make no sense.

Second if that is indeed a guid all the tables have another id; example would be Employee table would have employeeid and rowguid, why do this? My best guess is that you would use the guid to easily insert (linked/sync) data into multiple tables without needing to retrieve the id from the table that was first input into. My scenario would be inserting an employee; to insert an employee you need to create a row in the employee, contact and address tables and for ease you would use the guid to link these rows. But if this is the case wouldn€™t there be sync issues that would arise?

If my guess is totally off please correct me also if anyone can direct me to some good resources that cover database design.

The schema can be downloaded at http://www.microsoft.com/downloads/details.aspx?familyid=0F6E0BCF-A1B5-4760-8D79-67970F93D5FF&displaylang=en#filelist

DTS Package - Provider Generated Code Execution Exception: EXCEPTION_ACCESS_VIOLATI

When running a step within my DTS package I'm receiving the following error - "Provider generated code execution exception: "EXCEPTION_ACCESS_VIOLATION".

Inconsistency Between Data Source Designer And Underlying Code

Mar 28, 2007

I have 2 data sources that have recently been updated from SQL Express to full versions of 2005. The connection strings have been changed, and the changes appear in the code, but the data source designer still shows the SQLExpress portion of the connection string. This seems to be fouling up SSIS packages that are using these data sources. Has anyone else encountered this? If so, what can I do to fix this issue?

Package Validation Error : The Package Designer Deletes The Code From Script Task.

Jun 14, 2006

While Creating a script task in Control Flow, I am getting "Package Validation Error". Here is the complete message:

Error at Validate File and Load Data: The task is configured to pre-compile the script, but binary code is not found. Please visit the IDE in Script Task Editor by clicking Design Script button to cause binary code to be generated.
(Microsoft.DataTransformationServices.VsIntegration)

As mentioned in the message, I opened the script IDE and added the code I need. When I close the VSA IDE, package designer displays the same error message.

The worst part of whole story is that if I close the package designer and reopen it, I find that all the code I wrote in the script task has been deleted by the package designer. This is not at all acceptable as I saved the package the and still lost all my work. I did all the coding from scratch for that task.

Please respond if anyone faced similar problem.

Thanks in advance!

Anand

PS: If any one from Microsoft is reading this, please see what you guys are coding there. Due to the buggy software you deliver, I am loosing my credibility.<P< P>

Hello

I tried the Beta 1 of the service pack 1 to .net 3.5. If I try to add an entity (and try to save this), I get the Exception "No support for server-generated keys and server-generated values".

How can I add entities to my Sqlce- database?

I tried to give the id- column (primary key) in the database an identity, another time without identity, only primary key --> none of them worked. I always get the same error.

What do I have to change to make successfully a SaveChanges()?

How To Check If Value Is In Array Or Mv-param?

Dec 27, 2007

I'm working with a dataset something like this:

TypeID Sales($)
------ -------
1 123.45
1 47.98
2 9.21
3 87.23
3 99.88
4 123.43

And a multivalued parameter that lets the user select which TypeIDs specifically he wants to see:

ParamID ParamValue
1 Q1
2 Q2
3 Q3
4 Q4


And in my Report, I have data showing up something like this:

CountofAllSales: 6
SumOfAllSales: 491.18
CountofCustomSales: (count of sales with type specified in parameter)
SumOfCustomSales: (sum of sales with type specified in parameter)

The count and sum of custom sales should show -ONLY- the numbers from the TypeIDs selected in the multi-value parameter. But the CountAll and SumAll show everything, regardless. This is where I run into problems. I can't seem to find an "in" clause in the SSRS expressions. If the TypeID parameter was single value, I could write something like this

Expression for CountOfCustomSales:
=SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value, 1, 0))

However, since its multi-valued, that won't work. You'd have to write something like:
=SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(0), 1, 0)) +
SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(1), 1, 0)) +
....
SUM(iif(Fields!TypeID.Value = Parameters!TypeID.Value(length), 1, 0))

And obviously this doesn't work when you don't know exactly how many elements are going to be selected.

What would be ideal would be something like an "in" clause, but I can't find any such functionality or think how to write my own function:
=SUM(iif(Fields!TypeID.Value in
Parameters!TypeID.Values, 1, 0))

Short of modifying the StoredProc itself (and for me, that means red tape. :( :( ) can anyone think of a way to count/sum only the values specified in an MVP??

Multi Value Param Limit???

Feb 20, 2007

Is there a limit to how many items you can have in a multi value param list. I have 20 items in an activity type param and when I chose "Select All" and run the report, it doesn't return. I opened profiler and picked up the following statement sent to SQL:

exec sp_executesql N'SELECT de.employeenumber as Employee_Id,de.employeelastname + '', '' + de.employeefirstname + '', '' + case when de.employeemiddlename=''N/A'' then '''' else de.employeemiddlename end as Employee_Name,da.activitytype as Activity_Type,da.activitycode as Activity_Code,da.activityname as Activity_Name,dd.fulldate as Completion_Date,das.currentattemptstatus as Current_Attempt,das.successstatus as Success_Status,das.completionstatus as Completion_Status,das.registrationstatus as Registration_Status,fa.score as Score,fa.dimgradeid as GradeId

FROM dimemployee de inner join factattempt fa on (de.dimemployeeid = fa.dimemployeeid) inner join dimattemptstatus das on (fa.dimattemptstatusid = das.dimattemptstatusid) inner join dimactivity da on (fa.dimactivityid = da.dimactivityid) inner join dimdate dd on (fa.attemptenddateid = dd.dimdateid)

WHERE

de.employeenumber = (@EmployeeId) and da.activitytype in (N''CBT'',N''Course'',N''Dart'',N''Discuss'',N''Document'',N''Evaluator'',N''JPM'',N''Lesson Plan'',N''Module'',N''Observation'',N''Procedure'',N''PSG'',N''Qual'',N''Read'',N''Reference'',N''Session'',N''Sign-off'',N''Simulator'',N''Task'',N''Trainer'')

and das.isvalidattempt = ''Yes'' and ((@LastAttempt=1 and das.currentattemptstatus = ''Yes'') or (@LastAttempt=0 and das.currentattemptstatus in (''Yes'',''No''))) and das.lmsmartcompletionstatus in (@CompletionStatus) and (dd.fulldate >= @StartDt or @StartDt is NULL) and (dd.fulldate <= @EndDt or @EndDt is NULL)

ORDER BY de.employeefirstname + '' '' + de.employeelastname,da.activitytype,da.activityname,dd.fulldate',N'@EmployeeId int,@LastAttempt nvarchar(1),@CompletionStatus nvarchar(10),@StartDt nvarchar(4000),@EndDt nvarchar(4000)',@EmployeeId=108001,@LastAttempt=N'1',@CompletionStatus=N'Successful',@StartDt=NULL,@EndDt=NULL



If I take any one of the items in "da.activitytype in" out (for example....N''Trainer'')...the query is fine. But if I run it as is, it never returns. I have also reduced the number of items in the MVP to 19 and "Select All" and it runs fine...it just bombs when I have 20 and Select All. Any ideas?

StrdPrcdr Param Get All Values

Apr 21, 2008

Hello....
I am trying for several weeks to figure out how can I create a stored procedure with parameters that returns all rows from a column (even then Nulls) when the parameter value is not set (or is '%', or anything tha might be. In a few words, in case the user hasn't input any data).

I 've created a WHERE clause that goes like this: WHERE fieldName LIKE @param + N'%' OR IS NULL
Well this query returns all rows in case the user hasn't input data but if the user inputs data it returns the correct rows but it is also returns null fields.

Thanks a lot in advance!

DateTime Param For SP Causing BIG Headache...!!

Aug 8, 2006

I've got a stored procedure and one of the parameters is a DateTime.  But no matter what I do to the string that's passed into the form for that field, it doesn't like the format.  Here's my code: SqlConnection conn = new SqlConnection(KPFData.getConnectionString());
SqlCommand cmd = new SqlCommand("KPFSearchName", conn);
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter param = cmd.Parameters.Add("@DOB", SqlDbType.SmallDateTime);
param.Direction = dir;
param.Value = txtDOB.Text;

// also have tried this:

param.Value = Convert.ToDateTime(txtDOB.Text);

// and

param.Value = Convert.ToDateTime(txtDOB.Text).ToShortDateString;

No matter what I do I always get a formatting error - either I can't convert the string to a DateTime, or the SqlParameter is in the incorrect format, or something along those lines.  I've spent a couple hours on this and hoping someone can point out my obvious mistake here...??Thanks for your help!!eddie

Doing A SELECT X FROM Y WHERE Z IN (@param) In Stored Procedure?

Jan 21, 2005

Hello,

I have a table with a foreign key field. I need to retrieve all the records where the foreign key matches any of a set. In plain ol' SQL this is accomplished with the IN(a,b,c) statement but I can't get that to work in a stored procedure.

How would I do this? I can imagine that I could parse the input string and create a temporary table and use that to do a join but that seems rather convoluted.

Any tips highly appreciated! If I'm not being clear I'll gladly post more details.

Thanks,

Noc

Output Param With A Stored Procedure

Aug 21, 2001

Hello everyone,

I am working through a tutorial and have stumbled into something that does not quite make sense to me. I was wondering if someone could help me understand this.

I have created this SP, this all makes sense to me due to the assignment of the artistname column value to the @artistname variable. In other words what is on the right of the equal sign is assigned to what is on the left.

create procedure ShowPopStyle
@style varchar(30),
@artistname varchar(30) output
as
select @artistname = artistname
from artists
where style = @style
go

Now when you execute this SP, what does not makes sense to me is if I need to declare a variable to hold the output, which I presume is null, shouldn't the @returnname be on the left side of the equal sign instead of the right?

declare @returnname varchar(30) -- variable for the output from the procedure
exec showpopstyle 'Pop', @artistname = @returnname output
print @returnname

Thanks
Kevin

VB.NET Stored Procedure, Can't Pass Param

Jun 18, 2007

Hello,



I have a VB.NET stored procedure as below:




Code Snippet

Partial Public Class StoredProcedures

Public Shared Sub My_UpdateCountsManaged( ByRef paramInOut As Integer)

'here I perform update statement using "paramInOut" passed form calling code

.......

'then I return value to the calling code

paramInOut = 555

End Sub

End Class



Calling code specifies a parameter like this:






Code Snippet

Dim param as Sqlparameter = New SqlParameter("@paramInOut", SqlDbType.Int)

param.Direction = ParameterDirection.InputOutput

param.Value = 999

cmd.Parameters.Add(param)





When I execute the code, it surely gets back "555" from SP, the problem is that SP never gets "999" from calling code despite ParamDirection is InputOutput. It always receives 0. I am afraid I don't understand something fundamental ?

Any help would be appreciated.

Thanks a lot,Fly.

Why Is Param Query Effective Against SQL Injection?

Mar 12, 2008

Reading about SQL Injection attacks I came across this example:

SSN="172-32-9999';DROP DATABASE pubs --"
SqlQuery = "SELECT au_lname, au_fname FROM authors WHERE au_id = '" + SSN + "'"

One remedy given was a parameterized query as follows:

Dim cmd As new SqlCommand("SELECT au_lname, au_fname FROM authors WHERE au_id = @au_id")
Dim param = new SqlParameter("au_id", SqlDbType.VarChar)
param.Value = SSN
cmd.Parameters.Add(param)

Why does this parameter which is defined as a varchar solve the problem? It's defined as a varchar, basically a string. Why is the result different in the solution? How is the query string in the second sample different from the one in the first? A simple question I know, but I've been wondering.

Thanks

This sort of syntax is fine in C#, but fails in a query. I also tried using IN (@Status IN ('C'))


Is this sort of logic possible in TSQL or should I use two parameters and set them in my code as 1 or 0?

TIA

Passing Param - SSIS Package ??

Sep 21, 2007

Hi,


I'm exporting some data from a table to fixed-width file using SSIS.
The query inside the package is:


SELECT col1, col3, col6 FROM Table1
WHERE code = 5 AND status = 'S'


The 'code' value will be passed from the front-end.

How can I make the query dynamically take the 'code' value and export to a file?

If a user selects 'code' as 7 , then the query should change to


SELECT col1, col3, col6 FROM Table1
WHERE code = 7 AND status = 'S'


and with this it has to export to a file.


Is this possible? If so, any suggestions on how to do it? !!!


Thanks,
Siva.

Return BIGINT OUTPUT Param To VB!?

May 9, 2006

Please help me on this one.

I need to return a value to VB.
I've tried returning a numeric value NUMERIC(25,20) via an output parameter but this didn't work. I'm know at a point in wich I created a bigint and multiplied the value so that the decimals are gone. However it only returns NULL?!?!?!?!!?!?
Here's part of my stored proc

CREATE PROCEDURE dbo.uspCalcWeightedAverage @StartDate2 varchar(10), @EndDate2 varchar(10), @InMarket nvarchar(50), @InProductType int, @InWeekDay int, @WeightedAverage bigint OUTPUTAS......SELECT @WeightedAverage = cast(10000000000 * (SUM(HHF.FACTOR) / COUNT(PDF.FLAG)) as bigint)FROM TBL_PRODUCTDEFS PDF INNER JOIN #DATESBETWEENINTERVAL DBI ON DATEPART(HH, [DBI].[DATE]) = [PDF].[HOUR] INNER JOIN tbl_historichourlyfactors HHF ON DATEPART(D,DBI.DATE) = HHF.DayID AND [PDF].[HOUR] = [HHF].[HOUR] AND DATEPART(M,DBI.DATE) = [HHF].[Month]WHERE PDF.MARKETID = @InMarketID AND PDF.PRODUCTTYPEID = @InProductTypeID AND [PDF].[WD-WE] = @InWeekDay AND HHF.MARKETID = @InMarketID AND PDF.FLAG = 1GROUP BY FLAG

When I retrieve the output param it returns a NULL value. the properties in VB say that the parameter has the following props:
attribute 64 (Long)
NumericScale 0 (Byte)
Precision 19 (Byte)
Size 0 (ADO_LNGPTR)
Type adBigInt
Value Null

I try to return it with the following code (got the code from a friend)

Public Function RunProcedure(ByVal v_strStoredProcName As String, ByRef r_varParamValues() As Variant) As ADODB.RecordsetDim objAdoRecordset As ADODB.RecordsetDim objAdoCommand As ADODB.CommandDim lngCtr As Long On Error GoTo RunCommand_Error ' Create cmd object Set objAdoCommand = New ADODB.Command Set objAdoCommand.ActiveConnection = m_oAdoConnection objAdoCommand.ActiveConnection = m_oAdoConnection objAdoCommand.CommandText = v_strStoredProcName objAdoCommand.CommandType = adCmdStoredProc Call objAdoCommand.Parameters.Refresh 'Stop For lngCtr = 0 To UBound(r_varParamValues) If objAdoCommand.Parameters(lngCtr + 1).Direction = adParamInput Then objAdoCommand.Parameters(lngCtr + 1).Value = r_varParamValues(lngCtr) End If Next Set objAdoRecordset = New ADODB.Recordset objAdoRecordset.CursorLocation = adUseClient Set objAdoRecordset = objAdoCommand.Execute 'Stop For lngCtr = 0 To objAdoCommand.Parameters.Count - 1 If objAdoCommand.Parameters(lngCtr).Direction = adParamOutput Or objAdoCommand.Parameters(lngCtr).Direction = adParamInputOutput Then r_varParamValues(lngCtr - 1) = objAdoCommand.Parameters(lngCtr).Value End If Next Set RunProcedure = objAdoRecordsetRunCommand_Exit: ' Collect your garbage here Exit FunctionRunCommand_Error: ' Collect your garbage here Call g_oGenErr.Throw("WeatherFcst.CDbsConn", "RunCommand")End Function


PLEASE HELP.

Regards,

Sander
