I have a strongly typed dataset. I'm trying to read a record. I have the following
Dim ResourceAdapter As New ResourcesTableAdapters.ResourcesTableAdapter
Dim dF As Data.DataTable = ResourceAdapter.GetDataByResourceID(sID)
Dim RecResource As Resources.ResourcesRow
strBody = "The following link has been reported as broken. "
strBody = strBody & "Please verify before deleting." & Chr(10)
strBody = strBody & "Category: " & RecResource.Category & Chr(10)
strBody = strBody & "Title: " & RecResource.Title & Chr(10)
strBody = strBody & "URL: " & RecResource.URL & Chr(10)
where the GetDataByResourceID(sID) method returns a single row. I get the following error on the core line in bold:
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
Line 124: strBody = "The following link has been reported as broken. "
Line 125: strBody = strBody & "Please verify before deleting." & Chr(10)

Line 127: strBody = strBody & "Title: " & RecResource.Title & Chr(10)

What am I doing wrong?

I'm trying to read in a text file, fixed width, very long records (over 7000 characters) in an ssis package. The first record appears ok in the 'preview' in the connection manager setup, but each record after that is offset by 2 characters (record 2 offset by 2, record 3 offset by 4, record 4 offset by 6 and so on), like it's inserting special characters.
I have a client who needs to copy an existing sale. The problem isthe Sale is made up of three tables: Sale, SaleEquipment, SaleParts.Each sale can have multiple pieces of equipment with correspondingparts, or parts without equipment. My problem in copying is when I goto copy the parts, how do I get the NEW sale equipment ids updatedcorrectly on their corresponding parts?I can provide more information if necessary.Thank you!!Maria
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks, Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful: http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx
I have been able to create a sample file with two of my record types.
I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.
does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?
Thanks in advance for any help you might be able to provide.
Can anyone advise me as to how I can add the date and time to 2 columns in the sql server database for each record that is added. I'd prefer not to use the webform. Can sql server add the date automatically to the row? thanks
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
i have a matrix report and i want to switch the record background color with each record in the value column in that matrix report e.g 1st record background color is gray and next record background color is white and then the next record background color is gray ... and so on
I've been looking for examples online to write a SPROC to get some data. Here are the tables.
Album_Category AlbumCategoryID (PK, int, not null) Caption (nvarchar(max), not null) IsPublic (bit, not null)
Albums AlbumID (PK, int, not null) AlbumCategoryID (int, null) Caption (nvarchar(max), not null) IsPublic (bit, not null)
I need to return: -[Album_Category].[AlbumCategoryID] -[Album_Category].[Caption] -[Albums].[Single AlubmID for each AlbumCategoryID] -[Count of Albums in each AlbumCategory]
I hope I was fairly clear in what I'm trying to do. Any tips or help would be appreciated. Thanks.
I have a directory of user information. What I would like to do isallow someone to search for person X and then return not only theinformation for person X, but also the information for the next 15people following person X sorted alphabetically by lastname.So if someone searched for the lastname = "Samson", it would return:Samson, JohnSaxton, GregScott, HeatherSears, Rebecca.... (15 names following "Samson) ...How do you in SQL return a record set of X records starting atparticular record (e.g. lastname = "Smith)?Thanks in advance.
Hello. I have a database with a record that has two columns locked. descrip1 and descrip2. they are both nvarchar(max) columns. These are the only two columns of the record that remain locked. I am certain no user is accessing the record. I have even moved a backup of the database to my testing computer and the lock still exists. How do I remove the lock from these two columns on that particular record.
I can edit these two columns on other records. I have researched "Unlock" on MSDN but it doesn't seem to apply to t-sql. Any help would be greatly appreciated.
I have not yet succeeded in getting an aswer to this in a previous post, so I'll try again and rephrase the question
I have 2 fields, 1 called 'Created' the other 'Updated'
I would like to create a function, user procedure ,whatever in SQL something along the lines of...
FUNCTION myUID() RETURN Date(Today)+Time(Now)+USERNAME END FUNCTION
so that the value returned by the above pseudo code is something like '20080526T21:01:05.620SamL' where the date part is in yyyy0m0d format
I have got this working fine for the default 'Created' field but the calculated (and persisted) field comes up with something about being non-deterministic and refuses to play
Clearly something along these lines is a very straightforward requirement (I have it working fine in my 20+ year old database) , but have spent a week trying to get an answer (even from this forum) without success, so would be grateful for any help that you can provide me with to get round this barrier
I am trying to create package something like that..
1- New Customer table as OleDB source component 2- Lookup component - checks customer id with Dimension_Customer table 3- And if same customer exist : I have to update couple fields on Dimension_Customer table 4- if it does not exist then I have insert those records to Dimension_Customer table
I am able to move error output from lookup to Dimension_Customer table using oledb destination but How can I update the existing ones? I have tried to use oledb command but somehow it didnt work my sql was like this : update Dimension_Customer set per_X='Y', per_Y= &Opt(it should come from lookup)
How can we insert multiple records in a OLEDB destination table for each entry from the source table. To be more clear, for every record from source we need to insert some 'n' number of records into the destination table. this 'n' changes depending on the record. how is this achieved.
I tried checking to see if the point at which the reader was, that if it was the record I am looking for to go ahead and add the table data to a label. But for some reason it's only taking the first record in the database and not the one I thought I was at.[CODE] public void UpdateMaleHistLbl() { SqlConnection conn = new SqlConnection("Server=localhost\SqlExpress;Database=MyFamTree;" + "Integrated Security=True"); SqlCommand comm = new SqlCommand("SELECT * FROM FatherHistTable, MotherHistTable, UsersTable WHERE UsersTable.UserName = @usrnmeLbl ", conn); comm.Parameters.AddWithValue("@usrnmeLbl", usrnmeLbl.Text); conn.Open(); SqlDataReader reader = comm.ExecuteReader(); while (reader.Read()) { string usr = reader["username"].ToString(); usr = usr.TrimEnd(); string pss = reader["password"].ToString(); pss = pss.TrimEnd(); if (usrnmeLbl.Text == usr) { if (hiddenpassLbl.Text == pss) { maleHistLbl.Text = reader["GG_Grandfather"] + " > "; maleHistLbl.Text += reader["G_Grandfather"] + " > "; maleHistLbl.Text += reader["Grandfather"] + " > "; maleHistLbl.Text += reader["Father"] + " > "; maleHistLbl.Text += reader["Son"] + " > "; maleHistLbl.Text += reader["Grandson"] + " > "; maleHistLbl.Text += reader["G_Grandson"] + " > "; maleHistLbl.Text += reader["GG_Grandson"] + "<br /><br />"; } } break; //exit out of the loop since user found } reader.Close(); conn.Close(); }}[/CODE]Thanks in advance
Consider this scenario. I have two database in the sql server and consider that i have a query which has 4 tables inner joined. When i execute the query in the database1 , the query is returning rows, But when i execute the same query in the database2, the query is not retuning rows . I know that the no rows are returned because of missing data in the database2. But have no idea how to trace what values are missing in the database2. Please note the tables is having a huge list of records by which manually comparison is painfull. Please consider i dont have any background idea of the values in the tables but just using it. Any help would be appericated.
I have 2 tables they are identical what i need to do is when i make a update on one table the other table needs to reflect that same table. so lets say i insert into table A i need to look in table B if the record exist if it doesnt insert it if it does update it and if it exist in table B and doesnt exist in table A delete the record but i have to do this record by record..can anyone help me with this
I need to essentially do 2 loops. One loops through each record and then inside each record row, I want to perform an insert on each column.
Something like this maybe using a cursor or something else:
For each record in my table (I'll just use the cursor) For each column in current record for cursor perform some sql based on the current column value Next Next
So below, all I need to do is figure out how to loop through each column for the current record in the cursor
I hope you can help me. I posted this in the microsoft sql server newsgroupa few days ago and got no response so I thought I'd try here. If I canprovide any clarification I'll be glad to do so.I'm trying to calculate a column based on the value of the previous record.I'm not very experienced with SQL-Server.I'm using the following table:CREATE TABLE tblPayment([PaymentID] [int] IDENTITY (1, 1) NOT NULL ,[LoanID] [int] NULL ,[PaymentPeriod] [int] NULL ,[PaymentRecDate] [datetime] NULL ,[PaymentAMT] [money] NULL)I have a view based on this table. That view has the following calculatedcolumnsBeginningBalance: For the first record, this is equal to the loan amountfrom the loan table. For each additional record this is equal to the endingbalance from the previous payment record.Interest: BeginningBalance * the monthly interest rate from the loantablePrincipal: PaymentAMT - InterestEndingBalance: BeginningBalance - PrincipalIt might seem I could use a subquery to calculate the Beginning Balance asin:SELECT LoanID, PaymentPeriod, PaymentAMT,(SELECT SUM(PaymentAMT) FROM tblPayment AS tbl1WHERE tbl1.LoanID = tblPayment.LoanID AND tbl1.PaymentPeriod <tblPayment.PaymentPeriod) AS BeginBalanceFROM tblPaymentWHERE (LoanID = @LoanID)But this will not work, because the interest is calculated on the previousmonth's balance. I need to find a way to loop through the recordset. Isthis possible?Thank you,--Derek CooperDatabase9www.database9.com
Hi All,Have come across something weird and am after some help.Say i run this query where rec_id is a column of table arlhrl,select * from arlhrl where rec_id >= 14260This returns to me 2 records with rec_id's of 14260 and 14261Then I run this queryselect * from arlhrl where rec_id >= 14263This returns 7 records with rec_ids of 14263 up.How come the first query doesn't return the records returned by the2nd query also?If I select for 14262 no records are returned. It is like this is aphantom record or has an end of file character in it.I tried re-creating the indexes but to no avail. If anyone has anyideas about what could be causing it or how to fix it it would be muchappreciated.Thanks in advance,Andrew
Hey Forum, Below is a solution for passing a previous value (Height) to the current record in a view using two related tables (Plant= ID PK and plantHeight = ID FK) However, I was wondering how I could also do the reverse, that is, pass a next value to the current record.
hi guys, Can anyone advise me how how to read an excel doc i have stored locally? I need to be able to start the read from say row number 6 and finish the read once i get to a row that contains a pre-determined word signifying the end of processing. I intend to store the parsed data in an array that will be used as the data source for a gridview or repeater object on another asp page. I'm using ASP.net 2.0 and C# by the way. thanks in advance for any help!!!
Dim objCon2 As New SqlConnection() objCon2.ConnectionString = "a standard connection string" objCon2.Open()
Dim objCommand As SqlCommand objCommand = New SqlCommand(strSQL, objCon2) Dim objReader As SqlDataReader objReader = objCommand.ExecuteReader()
Label1.Text = objReader("email")
strSQL is a select command which I've checked (using SQL Query analyzer) does return data. I know the connection string is valid (and I presume if it wasn't that it'd fail on objCon2.open, which it doesn't).
So why oh why do I get this error on the last line (and yes, there is an "email" field in the contents of the reader)
System.InvalidOperationException: Invalid attempt to read when no data is present.
I have this code that I hacked together from someone else's example. I kind of understand how it works. I just don't know if it will and i am not in a location right now to check. I was wondering if I did this correctly first, second how can it improve and should i do something different. Basically i just want to check the password in a database. I am passing the username and password to this function from another functioprivate bool authUser(string UserName, string Password){ string connectionString = ConfigurationSettings.AppSettings["DBConnectionString"]; SqlConnection DBConnection = new SqlConnection(connectionString); bool result = false; DBConnection.open() SqlCommand checkCommand = new SqlCommand("SELECT password FROM Users WHERE userName='" + Password + "', DBConnection) SqlDataReader checkDataReader = checkCommand.ExecuteReader(); if(checkDataReader.GetString(0) == Password) { result = true; } else { result = false; } checkDataReader.Close(); DBConnection.Close(); return result;}Thank you Buddy Lindsey
Does anyone know how to read transaction log besides trace and profiler. The current situation is some one in our org. deleted an item and I'm trying to find out who and when.
I have some records that have been deleted. I need to find out who did it and to do that I need to read the logs. Are there any utilities that will allow me to read login 7.0? How about 6.5?
