SQL Server :: Failing Insert When Using Auto Increment?
Aug 6, 2010
I am trying to set up an insert command in vb for sql server (not mysql). the following works fine as long as I manually enter a new ASSalesId and don't have this field auto increment. this field is set up a a primary key. I would like to just use auto increment on this field. but every time I set the field to auto increment the insert fails. if I just remove the reference to this field from the statement the insert fails.
i am using one text box in New registration page. when ever user clicks on New registration button, The text box of record number should be auto incremented.
I want to insert a complete row with automatic increment and the PartsNo should be the same as the PartsNo from the PartsMaster table.
The medialink should be the PartsNo + '-2.jpg' The mediadescription is for example 'image2' The CatalogCode should be 'catalog' and the sorting code should be '0'
From The partsMaster table I Just need the PartNo So I can add this to the PartMedia Table. The PartNo is the foreign key in the PartMedia table.
The following I got so far but no luck
insert into dbo.PartsMedia (PartNo,MediaLink,MediaDescription,CatalogCode, SortCode) values (dbo.PartsMaster.PartNo, PartsMaster.PartNo+'-2.jpg','image2', 'catalog','0')
I use SQL Server and when I create a new table I make a specific field an auto increment primary key. The problem is some people told me making the field an auto increment for the primary key means when deleting any record (they don't care about the auto increment field number) the field increases so at some point - if the type of my field is integer for example - the range of integer will be consumed totally and i will be in trouble.
So they tell me not to use this feature any more.The best solution is making this through the code by getting the max of my primary key then if the value does not exist the max will be 1 other wise max + 1.Any suggestions about this problem? Can I use the auto increment feature?I want also to know the cases which are not preferable to use auto increment ..and the alternatives...note :: this question is general not specific to any DBMS , i wanna to know is this true also for DBMSs like
i was given a form in which empid is varchar and i m supposed to auto increment it using a function and calling it ....i have never done this. plz help me out the way .
i have a question, suppose i have a table 'tblImage' which have 3 rows of data and my auto increment is not +1.
imageId imageName 1 a.gif 2 b.gif 4 c.gif
i want to query '2' using LINQ C# to the table in MS SQL and show the record which i have done easily BUT now i want to get the next auto incremented value to make Next button on the sane web form, which is in this case is '4' and i also want the previous imageId as well.
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
I'm trying to get an IDENTITY column to auto-increment with each new row inserted, so that the field (userid in this case) can be used as a unique identifier.
However, I'm getting this error:
[Code]....
My code looks like this:
[Code]....
I don't understand - if I have to explicitly insert something into my auto-increment column, how do I know what to insert? Isn't the point of an auto-increment column that it's... auto?
I am using LINQ to store and retrieve data from tables with a clustered index key. However, I also need to know how to obtain an inserted table row identity with an auto-increment Primary key. The "Go To Definition" feature for my data context of dataClassesDataContext provides the following information:
[System.Data.Linq.Mapping.DatabaseAttribute(Name="EFMDB")] public partial class DataClassesDataContext : System.Data.Linq.DataContext
I am asking for the C# code that is needed in a button click event handler that will insert a row of data in a table named "Fields". It only consists of an auto-incrementing primary key column (FieldID), a string column (Phrase) and a null defaulted variable column.
rowid (int, not null) pid(nvarchar(1020), null) gid(nvarchar(1020),null) tid((nvarchar(1020),null)
I get value of pid, gid and tid from dropdown box. I would like to insert pid, gid, tid into TableOne. How to auto increase rowid when insert into this table?
I have an Insert into function returns the error Syntax error (missing operator) in query expression when text the single quote is send to the access db from a form.
' I need to replace this with the ascii ' before the query is sent.

i worked on a sample application integrating OpenID into ASP.NET Web Forms. It works fine when hosted locally on my machine. However, when I uploaded the application to a live server, it started giving "Login Failed".
You can try a sample here: [URL]
Here is the source code that fails to process the OpenID response:
