Failed To Convert Parameter Value From A String To A Guid?

Jul 3, 2007

 Hi all,
I have setup my database that have 3 columns:
1. Primary Key
2. UserId (UniqueIdentifier, Guid I guess) - I set it up so I can insert the value from the Membership table (UserId) for some relationship.
3.  Another Foreign key with just an int.
 
I tried to build a DAL, ran a test and received this error: "Failed to convert parameter value from a String to a Guid." Before I setup my UserId to be UniqueIdentifier and let it be just an Int, I don't have any problem retrieving data. Here is the SELECT query that I built with the DataSet:
SELECT     aspnet_Users.UserId, t_music.MUSIC_TITLE
FROM       t_user_viewed
JOIN        aspnet_Users ON aspnet_Users.UserId = t_user_viewed.UserId
JOIN       t_music ON t_music.MUSIC_PK = t_user_viewed.MUSIC_PK_FK
WHERE   aspnet_Users.UserId = @UserId
 
Any help would be greatly appreciated,
Kenny.

Failed To Convert Parameter Value From A String To A Datetime

Nov 1, 2007

Hi I am having this problem. I have created a stored proc that uses dynamic sql. Now this works fine when I use it in Query Analyzer.

Now when I try to use this in Reporting services it gives me the error:
'
Failed to generate fields for the query
Check the query syntax or click refresh on query toolbar.
Failed to convert parameter value from a string to a datetime
'

My sotred proc is as:

<quote>
-------------------------------------------------------------------------------------------------------------------------------------

CREATE PROCEDURE [dbo].[rptDetailedAuditsIssued]

(

@param1 varchar(50) ,

@param2 varchar(50),

@param3 varchar(50),

@param4 datetime ,

@param5 datetime



)

AS

begin

declare @strSQL varchar(500)

set @strSQL = 'SELECT * FROM v_DetailedAuditsIssued WHERE '

if @param1 <> ''

Begin

set @strSQL = @strSQL + 'strRegion = ' + @param1 + ' AND '

End



if @param2 <> ''

Begin

set @strSQL = @strSQL + ' strTaxTypeCode = ' + @param2 + ' AND '

End

end
--------------------------------------------------------------------------------------------------------------------------
</quote>

When I run


rptDetailedAuditsIssued '','','','1/1/2000','1/1/2001'in query editor it runs fine. But gives me that error every time I run it in SSRS. I think I got this problem but in earlier cases I used to set the param values to null in Repservices and it worked but its not working this time. This time it stops complaining but does generate any fields.

How Do I Convert A String To An Integer For A Parameter?

Dec 14, 2006

I want to convert a string into an interger so that my parameter can get one value, and have a seperate matrix list the value before the value selected.

My parameter is year. The user picks the year. And i want the crashcounts for the year displayed in the matrix. Then i have another matrix with a dataset similiar. I want this seperate Matrix/Dataset to display the previous year.

SO if the user selects 2004 from the dropdown. 2004 is displayed in the first matrix, and 2003 is displayed in the second matrix. The year attribute is in string format, and i cant change it in the cube. So i was told it could be converted in reporting services. with this



=CStr(CInt(Parameters!CrashStatisticalYear.Value)-1)



Question is, where do i put this...and how come when i put it in the parameters expression for the 2nd matrix, i get an error datatype messege? HELP !

How To Convert GUID GuidConverter ConvertTo Int32

Feb 15, 2007

Hi,
Can anyone help me figure out how to convert from type GUID to int32 format which will be the format to store in sqlserver database?
I have retrieved the UserId of a particular user in the current users profile (which is also a field in a row of data  in table aspnet_Users) using this method:
MembershipUser user = Membership.GetUser(CreateUserWizard1.UserName);
and now would like to cast the following
user.ProviderUserKey type int32.
I thought the way to go was to use a GuidConverter  by doing such as below by first assigning the user.ProviderUserKey in the _UserID variable and then calling:
TypeConverter converter = TypeDescriptor.GetConverter(_UserID);
Int32 newUserId = (Int32)converter.ConvertTo(_UserID, typeof(Int32));
But it blows up!  any ideas?
thanks

How To Convert SQL Unique Identifier In A Csv File To A SSIS GUID Variable

Aug 21, 2007

Here's a problem description I read on another post but I have the same issue:

I am trying to Import Data from a csv file into a SQL Sever table. The Data being imported has a Unique Identifier in it but it is being considered as DT_WSTR datatype in SSIS



When i directly try to import, it gives an error:



The conversion returned status value 2 and status text "The value could not be converted because of a potential loss of data.".



I Tried to use Data Conversion to convert it to DT_GUID and import into SQL Server table but it again throws the above error.
Anyone has a clue?

Thanks!

Testing StoredProc With GUID Parameter

Apr 11, 2002

I am working revising a number of stored procs on a system which has suffered some schema changes.

Sometimes I can test my SP code passing in a guid without a problem. Example below:

Test Command:

EXEC usp_Unit_INSERT
'{74A1BABA-0B76-4436-B6AA-01716B686044}', --unitguid
'36', --91', --UnitNumber (varchar)
10, -- xxHospitalNumber
'testUnknown' --UnitName

Above works fine.

I am testing another similar stored proc and am getting this error:

Server: Msg 8152, Level 16, State 9, Procedure usp_Patient_Info_INSERT, Line 24
String or binary data would be truncated.
The statement has been terminated.

(Line 24 performs an insert to a GUID)

Pertient code portions below.
Can anybody shed any light. I am essentially doing nearly identical things to another Stored Proc which works just fine.

Code below fails with above error, but is virtually identical in how it treats all GUID fields to another which does work fine.

-------------------------------------------------
CREATE PROCEDURE [usp_Patient_Info_INSERT]
@PatientGUID varchar(40),--uniqueidentifier,
@PersonGUIDvarchar(40),--uniqueidentifier ,
@CaseNumberdecimal(10,0),
<< and so forth >>

AS
IF @PatientGUID Is Null
SET @PatientGUID =cast( (newid()) as varchar(40))

INSERT INTO [Patient_Info] (
PatientGUID,
PersonGUID,
CaseNumber,
<< and so forth >>

Values (
cast( @PatientGUID as uniqueidentifier),
cast( @PersonGUID as uniqueidentifier),
@CaseNumber,

<< and so forth >>

Creating An All Option For Parameter Value In GUID Format

Jan 31, 2007

I am working with SRS 2005 SP1 which no longer has the "ALL" option available on parameters. I am trying to create an "ALL" entry in a picklist so it can be used in a where clause for a dataset. I have a dataset with a union statement that creates a list of CRM usersids and names and an entry with a dummy guid with the name "All". Parameter is defined as a string type, with a dataset providing a list of users (label field) and their corresponding GUID value (value field), along with the an "All" entry.

select systemuserid, fullname
from FilteredSystemUser
Union
Select '00000000-0000-0000-0000-000000000000' as systemuserid, ' All' as fullname
order by fullname

The issue I am running into is implementing logic in another dataset referencing my parameter.

All is fine in the where clause if it is structured "where ownerid in (@Users)" but if I try to add logic to check for the "All" option "where (ownerid in (@Users) or @Users = '00000000-0000-0000-0000-000000000000') it errors out.

How do you impement "All" when you're dealing with a GUID type field? Thanks.

How To Pass A GUID String To A Varchar In SQL Stored Procedure

Aug 26, 2007

In my .NET app I have a search user control.  The search control allows the user to pick a series of different data elements in order to further refine your display results.  Typically I store the values select in a VarChar(5000) field in the DB.  One of the items I recently incorporated into the search tool is a userID (GUID) of the person handling the customer.  When I go to pass the selected value to the stored proc  

objUpdCommand.Parameters.Add("@criteria", SqlDbType.VarChar).Value = strCriteria;
I get: Failed to convert parameter value from a String to a Guid.
Ugh!  It's a string, dummy!!!   I have even tried:
objUpdCommand.Parameters.Add("@criteria", SqlDbType.VarChar).Value = new Guid(strCriteria).ToString();
 and

objUpdCommand.Parameters.Add("@criteria", SqlDbType.VarChar).Value = new Guid(strCriteria).ToString("B");
but to no avail.  How can I pass this to the stored proc without regard for it being a GUID in my app?

Passing GUID Into Dtexec, Invalid Cast To A String Variable. Solution??

Oct 4, 2006

I am getting an invalid cast specification when I call dtexec and try to /SET a user variable within the package that is defined as a string data type. Is there any solution to this? I have tried passing the GUID with {} w/o {} w/ '' w/ "" etc.. many variations... and still get an invalid cast specification. Is there a data type that I need to set the User variable to besides String? The User Variable is used to Select records from a SQL data source where the GUID is stored. I do not have an option of GUID data type for a User Variable.

Thanks for any help! Aaron B.

Example

Table1 has a varchar which i want to cast to int

but for some reason it dosent look like they match, although they look the same. maybe a type problem?

How To Convert A Hex String To An Integer?

Feb 1, 2000

Hi folks,
I'm trying to import data from a text file (UnicodeData.txt) into
an SQL table. Some of the fields are unicode values (16 bits)
expressed as four hexidecimal digits. I've succeeded in importing
the data as character strings, but I have not found a way to convert
them into numbers. (They could be stored as int or nchar.)
I've tried convert(binary/int/whatever, string); E.g.
select convert(int, '0x1111') from import_unicode
gives the error
Syntax error converting the varchar value '0x1111' to a column of data type int.

I could write code to strip off one character at a time, convert the
hex digit to a decimal value, shift left, etc., but I find it hard
to believe that's the best way.

Any help is appreciated. Please email answer to lars_huttar@sil.org
as I don't read this board.

Thanks,

Convert String To Date In DTS

Dec 7, 1999

I'm using SQL 7.0 SP1.

I am using DTS to read in a date with the format of YYYYMMDD. I am trying to convert this date to MM/DD/YYYY and then use the CDate function with the following code to load it into a Datetime column in SQL Server:

Function Main()
strDate = DTSSource("Col002")
strYear = Left(strDate, 4)
strMonth = Mid(strDate, 5, 2)
strDay = Right(strDate, 2)

strHoldDate = strMonth + "/" + strDay + "/" + strYear

DTSDestination("DateName") = strHoldDate
Main = DTSTransformStat_OK
End Function

My DTS package will execute without errors, but it does not add the row. I have been successful using CDate when the source date is in the format MM/DD/YYYY.

Also, do you have any tips on how to debug DTS? How to see what's in a variable, etc.?

Thanks!
Lisa

Convert String To Hex And Concatenate With

Sep 4, 2014

To start, I am NOT a SQL programmer. I have to do some minimal SQL administration (DB Creation, Backups, Security) on spatial databases that are for the most part managed by a 3rd party program. My experience with T-SQL is mostly simple tasks (i.e. Select and Update statements)..However I have been requested to calculate an ID Field using the values of two other fields. Per the request, I need to convert one field to Hex and concatenate with the second field.

ex. Field 1 + Field 2(hex string) = Field 3
Field 1 = 'FF02324323'
Field 2 = 'Smith Creek'
Field 3 = 'FF02324323536D69746820437265656B'

Field 1 VarChar(10) (Code)
Field 2 VarChar(65) (Common Name)
Field 3 VarChar(max) (ResourceID)

Spent half the day searching and have tried various forms of CAST, CONVERT, fn_varbintohexstr and others but have unable to come up with the correct combination to get what I need.

Query To Convert String To Int

Oct 4, 2007



CREATE TABLE USERTABLE(
USERID int,
USERNAME varchar(20));

INSERT INTO USERTABLE VALUES (1,'x');
INSERT INTO USERTABLE VALUES (2,'y');
INSERT INTO USERTABLE VALUES (3,'z');


CREATE TABLE ACCESSTABLE(
ACCESSTYPE varchar(50),
USERIDS varchar(20));

INSERT INTO ACCESSTABLE VALUES('Enabled Users','1,2');
INSERT INTO ACCESSTABLE VALUES('Disabled Users','3');

Select USERNAME from USERTABLE where USERID IN (select USERIDS from ACCESSTABLE where ACCESSTYPE='Enabled Users');


I get the following error for the above query.

Syntax error converting the varchar value '1,2' to a column of data type int.


Please advice me.
