Insert GUID Returning Null

Jun 5, 2006

I am trying to insert a record to based on the source below, however the GUID of GiftOcc_ID is being returned as zero's so the first record can be added but as it is defined as the primary Key and uniqueidentifier the next record fails with a duplicate entry. Basically how do I ensure that the GUID is created and not nulls. As you can see I am trying to use Newid() which I have inserted as a default value but that does not work. Also as it is a unique identifier the "is identity" is not available

 

Protected Sub CreateGiftOccasion(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click

Try

Dim null As New Nullable(Of Integer)

Dim da As New DataSet2TableAdapters.Gift_OccasionTableAdapter

Dim GiftOcc_ID As Guid

da.Insert(newid(), Occ_Type_Text.Text, Occ_Desc_Text.Text, Calendar1.SelectedDate, Calendar2.SelectedDate, 1)

Catch ex As Exception



Response.Write("Ooops")

End Try

End Sub

 

The code from the table adapter regarding inserts is:

<InsertCommand>

<DbCommand CommandType="Text" ModifiedByUser="False">

<CommandText>INSERT INTO [dbo].[Gift_Occasion] ([GO_ID], [Go_Type], [GO_Description], [GO_DateOn], [GO_DateOff], [GO_Active]) VALUES (@GO_ID, @Go_Type, @GO_Description, @GO_DateOn, @GO_DateOff, @GO_Active);

Return GUID On Insert

Oct 24, 2007

once upon a time someone told me how to do this, but i forget, and it was for classic asp..
 so what im trying to do is create a new record (a workstation) and get back the auto generated ID (its not actually a GUID, its an int which is set to the identity) and then once i have that create other records (for external devices, different table) that will have a link to which machine they are attached to (that Id im looking to get returned)
I know this can be done in a two step process, create the record, query it for its id, and then slap that in my next insert statement for the external devices... but... i know there was a way to do it before and i assume there is a way to do it now...
anyone know how?
Thanks
Justin

Retrieving GUID From INSERT Query -- HELP

Aug 27, 2007

I have tried many code sample but I am very stuck

The primary key of my database (SQL server 2005) table is a uniqueidentifier.


I am using the following code to insert a row into my table:

myCommand.CommandText = sqlEvent.ToString(); //add the sql query to the command
myCommand.Connection = this.dbConnection; //add the database connection to the command
myCommand.ExecuteNonQuery(); //execute the insert query


I need to retrieve the GUID that is automatically generated when the insert command is executed.

Can someone help me? How do I get the GUID that is automatically generated? I have tried lots of things like using

string _id = (string)myCommand.ExecuteScalar();

and I am still stuck. I will really appreciate it if someone can refer me to some code sample.

SQL Returning Null

Feb 13, 2007

Thanks to everyone in advance

The code below returns the members who have accounts that are inactive, and works correctly.
It returns the memberid, but returns null values for the barcode values.
I am explicitly looking for unmatched rows, i.e. the LEFT OUTER JOIN will return joined member-address
rows which do not have a matching account, according to the ON conditions, and these are the ones I want
because of that WHERE condition.
Therefore account.barcode will always be NULL too.

Is there to perform the same query and return account details?
I have tried running a query to return just the memberid values and then perform a second query to match the account
details, but this is very ineffecient and slow.


select member.memberid, account.barcode
FROM member
INNER
JOIN address
ON address.MemberID = member.Memberid
LEFT OUTER
JOIN account
ON account.Memberid = member.MemberID
AND account.enddate >= current_date
AND account.closed = 0
WHERE account.Memberid is null AND member.isDeleted = 0

Special thanks to r937 for help.

i have 2 stored procedures: a delete and a select.  the delete sp returns the rowcount properly.  the select returns null.  the code for both sp's is extremely simple and extremely similar.  when i execute the select sp in server management studio the rowcount shows a 1 as expected.  but the calling method gets null.
SP Code

Returning Null Values

Jun 4, 2007

I have a simple table on my webpage which shows data from my database.
It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value.
I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work.
If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.

@@servername Returning NULL

Mar 9, 2006

I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers. I have replication configured on this so i am not able to do a Sp_dropserver & sp_addserver as this acts as a publisher. The configured merge repication stopped working because of this issue and I am not able to delete replication as the the delete option uses @@servername which returns a null value. So I am struck in a loop.

Any advice is appreciated.

Shortcut To Insert New GUID Into Uniqueidentifier Cell In MSSQL Management Studio Express?

Jul 15, 2006

Hi,

anyone knows if there's an easy way to insert new GUIDs into uniqueidentifier cells when editing data in table on Management Studio Express? or Visual Studio 2005 Server Explorer? I can't find a shortcut, and copying from external tools is pain..

I suppose it's possible to build a VB macro in Visual Studio, would it work when editing table data?

Thanks in advance!

SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.

Java Code Returning Null Resultset

Hi,

Here's a snippet of my java code :

Code:

resultSetSQLServer = statementSQLServer.getResultSet();

System.out.println("b = " + b);
System.out.println("Are there any rows ?? " + resultSetSQLServer.next());



This code is returning null resultset.

But when I fire the same query directly into MS SQL, it is returning the corresponding rows.

I dont know where i'm going wrong. But just to make things more clearer, here's my connectivity code :

Code:


Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
connectionSQLServer = DriverManager.getConnection("jdbc:odbc:dm", "user", "pass");

statementSQLServer = connectionSQLServer.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);

ASP Returning Null Sized Field From MS SQL Database

Jul 20, 2005

We currently have an SQL db running on a web server.One of these fields is a large(ish) amount of text data – up to 400characters – and has been cast variously as varchar, nchar and texttype to overcome a problem. The problem appears to be in retrievingthe data via ASP. I understand that ASP can handle string data of thissize so I am okay there.When the records are retrieved from the db, the data string length =0.I know the data is there because I have written a Delphi data managerwhich interrogates the db and shows all records and their contents.So if ASP can handle strings this size and the data is there, why do Iget a data length of zero bytes returned when I interrogate the recordset?Whichever way I cast this field I get the same result.I know the code is sound as it works locally through a MS SQL serveron my PS.Anyone have this problem or know what's causing it? I have logged asupport call with my hosting company, but they haven't replied as yetand I am stuck on an urgent project.Any suggestions?CheersGrant

Parameter Issues When Returning Null Records

May 14, 2008

Hi,

I'm running into an issue where if a report retrieves 0 records, I run into an error. My report has 2 queries-- the main query to retrieve Account information and the other to return Contact information based on the contact id(s) returned by the Account query. The reason needing two separate queries is that the contact and account tables are on different databases.

Now here is my account query: select contact_id, username, password from account.
My contact query looks like this: select name, address, .... from contact where contact_id = @contact_id.

In my report parameters, I define contact_id like this:
*******************************************
name = contact_id
data type = integer
prompt = [blanked out]
hidden = checked
internal = checked
multi-value = unchecked
allow null value = checked
allow blank value = unchecked

available values:
from query: dataset = account
value field = contact_id

label field = contact_id

default values:
from query: dataset = account
value field = contact_id
**********************************************

Now, when I run my report and knowing there are no records, I get the following error: "The 'contact_id' parameter is missing a value". Any ideas on how to solve this issue? Thanks.

Integration Services :: SSIS Bulk Insert Fails On Unicode File With GUID Column

I am using SQL Server Data Tools for Visual Studio 2012. I have a very simple SSIS package with a Data Flow task that exports from an OLE DB Source to a tab-delimited unicode Flat File Destination and a Bulk Insert task that loads from the file. Both the Flat File Destination and Bulk Import are using the same code page. The Bulk Insert task is using the wide char format to read from the file. The process works fine with nvarchar and int columns, but when I add a unique identifier column it fails with "type mismatch or invalid character for the specified code page".

public static DataTable getCart() {        DbCommand comm = GenericDataAccess.CreateCommand();        comm.CommandText = "sp_cartGetCart";
        DbParameter param = comm.CreateParameter();        param.ParameterName = "@CartID";        param.Value = cartID;        param.DbType = DbType.String;        param.Size = 36;        comm.Parameters.Add(param);
        DataTable table = (GenericDataAccess.ExecuteSelectCommand(comm));        return table; }
public static DataTable ExecuteSelectCommand(DbCommand command)    {        // The DataTable to be returned         DataTable table;        // Execute the command making sure the connection gets closed in the end        try        {            // Open the data connection             command.Connection.Open();            // Execute the command and save the results in a DataTable            DbDataReader reader = command.ExecuteReader();            table = new DataTable();            table.Load(reader);            // Close the reader             reader.Close();        }        catch (Exception ex)        {            Utilities.SendErrorLogEmail(ex);            throw ex;        }        finally        {            // Close the connection            command.Connection.Close();        }        return table;    }
