Friends,
I am inserting a value from vb.net to sql server 7.
i created a table in the sqlserver with primary key.
In VB.net form i didnt check the values of the check box.
when i try to save the empty or null the sql server should throw the error. but its accepting the null value.
how is it possible?
can anyone help me?
FYI:
table name: JobMast
Fields:
jobcode int primary key
jobtitle varchar(10)
I am trying to have a query with the option for items to be null. (So users don't need to fill in the other fields if they choose not too) SELECT Tickets.TicketID, Tickets.UserID, Tickets.SystemID, Tickets.Title, Tickets.Description, Tickets.Software, Tickets.Date, Systems.OS, OS.OS AS OstitleFROM Tickets INNER JOIN Systems ON Tickets.SystemID = Systems.SystemID INNER JOIN OS ON Systems.OS = OS.osIDWHERE (Tickets.Title LIKE '%' + @title + '%') AND (Tickets.Software LIKE '%' + @software + '%') AND (Tickets.Description LIKE '%' + @descrip + '%') AND (Systems.OS = @osid) OR (@osid IS NULL)This works when i give the LIKE values % as a parameter. So they can choose to search by title + software but not description or description and nothing else etc etc etc. The problem is, the osid. If I give it a value it works but if i try to do null, *. or % it always displays every item in the databse ignoring any of the previous like statements. Anyone have an idea?

View 14 Replies View RelatedI have straight forward Insert Query, which takes values mainly from text boxes, however I am having trouble when the value is null.
eg
cmdP0.Parameters["@EmpID"].Value=txtEmpNo.Text;
When I run the Query I get...
Message="Parameterized Query '(@ID int,@EmpID int,@Photo nvarchar(260),@DoB smalldatetime,@Med' expects parameter @EmpID, which was not supplied."
I also get this when the parameter can be a string.
I have set the parameter properties so that SourceColumnNullMaping to true (it was set as false - so hoped this might fix it!)
No luck.

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

I am trying to audit data quality based on some defined data quality rules. The rules are stored in tables and processed using stored procedures. I am facing a problem while generating audits.

Its the PrimaryKeyAttributeValues column I am facing problems with. I am using STUFF function within a dynamic SQL query to get the primary key's as a list of comma separated values.
I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?

Hi
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task.
In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful.
Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
If Not Row.Datum1_IsNull Then
Row.OutputDatum1 = Row.Datum1
Else
Row.OutputDatum1 = CDate(System.Convert.DBNull)
End If
Any help welcome.
Hi,
As I try to do an insert using an stored procdure I get an error reading...

Thanks in advance!

Hi,
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
e.g.
Rank Blah Blah
1 - -
2 - -
3 - -
NULL - -
NULL - -
At present the NULLs are at the top of the list, but I do not want my ranking in descending order. Any suggestions?

What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.

Using TSQL, I have a table that holds filenames of Pictures for products. Different products can be using the same picture. I need to select the filenames for a single product only if it does not exists for a different product.I have tried Where Exists (select FileName From Tbl where

Prod_Id != @var) In the Select Statement.
Cannot find an answer to this in previous posting, though there are similar topics.
My primary key "ID" requires a value (is not nullable), and not explictly providing it with one when I update a new record gives the following error:

Cannot figure this one out. The value I'm providing for that field is known to be unique, but the SQL Server spits it out each time.
Is there a way to have the ID primary field automatically update with a new value when a new record is generated? This is how I used to do it in Access, but cannot find a similar feature in SQL Server. I'm sure I'm missing something simple, but right now I'm stuck in this "Catch-22" situation.

View 1 Replies View RelatedHello group:I've done alot of reading on this subject somewhat and have found thatmany people have many different opinions on this subject. My questioncenters mainly around using a lookup table to enable users to select apre-defined list of values.I have developed a practice myself of avoiding AutoNumber type datafields for primary keys where the primary key will be related to achild table. Nevertheless, what do most users do with lookup tables?My thoughts are to create a small key value for each value in thelookup table. For example:I might have a Carriers table which shows a list of carriers that Imight ship an order by. One of the entries may be 'Air Freight -Overnight', or 'Air Freight - 2nd Day Air'. I've seen a few exampleswhere the primary key field for each entry like these would beautonumber, or at least, a numeric value. What I like to do is createmy own key, like for 'Air Freight - Overnight', I might use 'AFO' forthe key, and for 'Air Freight - 2nd Day Air', I might use 'AF2'. Anythoughts on this? Mine are that even tho the users may never see thisvalue - I, as the developer will see it and I tend to prefer a keyvalue based on real data that means something other than anauto-incremented number. In referencing the well-known Northwind.mdbdatabase, I noticed their Categories table used a number field value,like 1, 2, 3....etc, but their customers table used values like'ALFKI' to represent their key values.What are some other thoughts out there? I'm working with Accesscurrently, but this project is about to move to SQL Server.James

I am using ODBC to access MS Sql Server 2000 Enterprise(& Prof.) Edition. While running some queries, I occassionaly get following error :-
Error Text : [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionWrite (send())"
Error No : 10054
Source : Microsoft ODBC driver for SQL Server" as source.
IMO, Its not related to specific query as I get it for different queries at different time and its infrequent.
I have found a MS KB article for the error that says this error is possible in long queries if lightweight pooling (fiber mode) setting is enabled for SQL Server and the fix is to use SP2. I am already running with SP2 installed.
I could not find another reference to this error. And as I am unable to locate cause of problem, I am not able to troubleshoot it. Any help will be appreciated.
Thanks.

In oracle The simplest description of instance : combination of memory and process architecture
I sql server, what is the Instance.? it is combination of memory and process architecture if yes then pls give name those processes ?
I would like to get the primary key values in a DML CREATE TRIGGER as follows:
CustomerID = 12 AND InvoiceID = 50
I create the DML trigger for UPDATE and DELETE only, how do I retrieve the values as above ?
Jon Galloway provided a sample in http://weblogs.asp.net/jgalloway/archive/2008/01.aspx but the Primary Key Field and Primary Key Value were inserted into separate columns while I need to combine the Primary Key Field and Primary Key Value into 1 single field, using his example, I want to form the primary key as:
ScoreId = 423
ScoreId = 3064
etc.
Note that his example only show a single primary key in a table whereas I need to handle multiple primary keys in a table.
We are facing the following issue, several machines/users that are executing very often a command similar to :
INSERT INTO TableName (FieldOne,FieldTwo) VALUES ('ValueOne','ValueTwo');
SELECT SCOPE_IDENTITY() AS Table_ID;
Where TableName has a primary key defined as identity(1,1).and that Table_ID is being used as reference in others tables
These queries are executed using different dababase users and among several diffrent apps..The Problem is that we are detecting lost block of "Table_ID's" as the other tables shows the InsertedID as a reference, but the TableName table lacks of this ID record. In other words, the INSERT seems to work, the SCOPE_Identity returns an InsertedID, and the other tables are populated using this number. However, when we query the TableName table the mentioned record does not exist. We are profiling the server and we're sure that there are no DELETE statement on the TableName table. This seems to be happening when the are either deadlocks or blocked processes. Whenever the deadlocks and locks disappear/solved, everything works as expected.why the Scope_Identity returns the Inserted ID if the INSERT action had failed.
I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.

what other method can you use to generate primary keys automatically. My boss disagrees with me using identity for the primary keys. He says it is not professional. I am working on SQL Server 2005 platform. Can anybody advice me?

Hi all,
I've had this problem for a while now and I'm looking for a better solution.
I'm pulling through a dataset from a SQL Server 2005 database and populating it into a DataGridView. The end user updates information on the grid and I then want to updates the results in the SQL Server table. My table has a compound primary key made up of two fields.
I'm currently looping through the data grid and for each value identified to update I'm executing a stored procedure that takes the two fields as parameters. However I know that this method isn't very efficient, especially if the user wants to update a few hundred records as it will execute the stored procedure a few hundred times.
Is there a way I can pass the two parameters in an ArrayList or something like that? I need SQL Server to be able to take the parameter. Is XML the way to go or is there any additional support in the .NET framework for such problems?
Thanks for your help.
