DataSource Controls :: Insert Sequential Numbers Into A Primary Key Column Using A Script?
Jan 29, 2010
I need to insert multiple records using a script.
My table is
Region
(
ID int,
Name varchar(50),
Description varchar(51)
)
One thing I can use is to retrieve the max(ID) from region and store it in a variable and increment the variable sequentially and insert. But, if any other user inserts a record while I am executing this script then max(id) might clash with the id inserted with other user causing my script to fail.
Is there any other option to insert record sequentially base on the highest number in the table.
I am using LINQ Expression to insert records in SQL Table. My Table dosen's have any Primary Key Field. Whenever I Am trying to Insert Records in Table using LINQ Expression, this always occurs an Error that 'the Table You are using to insert Dosen't Have Any Primary Key Field.
How I Will Insert Records Without Having Primary Key ?
When a user creates an account for my web application using the create user wizard additional steps have been added to take more details and store them in another table. Now this tables primary key is set to uniqueidentifier, is it possible to have that unique identifier automatically generated when the query is run to insert a new row for a new user?
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
I would like to be able to read the first row of a table and then each successive row sequentially individually. So, is there a way to read the first row of a table, whatever the primary key may be, and then read the next sequential row in the table until the last row has been read? I need to be able to do this in order to create a list of column entries in each row for a listbox control that a user can select from.
when I insert any character to column Name then A new string random will auto insert into column Random (picture below) I had used Trigger but It was error !
I want to column Random use to code :
DECLARE @myid uniqueidentifier SET @myid = NEWID() insert into table_1 values(@myid, substring(CONVERT(varchar(255), @myid), 1, 5))
but It must auto like column Number (column Number is Identity)
I have an orders table with a column names orderID. What I want to do is insert a new record and get the value from the new orderID column. The orderID is my Primary key. The Insert SQL I have now is -
INSERT INTO orders (creditAutorizarionNumber, OrderName, OrderPersonPhone, OrderPersonEmail) VALUES (@creditAutorizarionNumber,@OrderName,@OrderPersonPhone,@OrderPersonEmail)
How do I write the query to get the newly entered orderID ?
how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.
I am trying to create a stored procedure where I can insert null values in columns that have a foreign key constraint and allow nulls. The columns I am trying to insert nulls into are commentid and imageid. I have created an Insert statement in a stored procedure and I get the foreign key constraint error. Can you tell me how to allow inserting data in the other columns without having to insert anything in the commendid and the imageid?
Here is my exec of the stored procedure that is not working:
Let's say I have a table that holds information about books, with a column called bookid as a primary key with auto increment of 1. When I create a couple of records, it assigns 1 to the first row and 2 to the second row for the bookid column. If I delete the second row and enter another row, even though table now only has 2 records, the primary key column says 1 and 3 for their bookids. Is it possible to change back the bookid of the second record from 3 to 2 or is it just server assigned and can't be changed.
In my application, users fill out a form to submit a "Job Request" - once they submit the form it is stored as a new row in a table in the Sql database. Each "Job Request" that is submitted is given a "JobID" which is a number and also the primary key of the new row in the database (the number is generated by the database). Once the users hit the "submit" button, I'd like to return the value of the "JobID" (the primary key) so that the user can know what it is. How would I achieve this? In the future, I will have to expand the application so that the users would be able to edit an older "Job Request" and get a similar JobID number (so if before it was 1234, the new one would be 1234-1 or something like that), so this is not simply a matter of searching for the highest number in the primary key field in the table and returning that. I'm using Sql for my database and writing in VB.
Yes..i know this is ASP.NEt forums but the SQL server doubt i will be going to ask is related to ASP.NET
I have a table 'a' in my database where i store User information - each time they visit the website a new record is added
so in a high traffic website - the information will be collectively huge(i dont care about this as i have too much of disk space)
but the problem here is with the primary key - I want a datatype of the primary key which should never end Bigint can store some zillions of records but it finally ends... how will i be able to accomplish it.
My codes below are to insert a new data into the database. The thing is, this code can insert the primary key(DeviceID) into the database automatically but I cant seem to find the code to insert the primary key into the database. point me the statement that insert primary key(DeviceID)..
This is the snippet of the submit button event
Protected Sub SubmitDevice_Button_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitDevice_Button.Click If Session("canUploadBool") = False Then ClientScript.RegisterStartupScript(Me.GetType, "canuploadScript", "") Exit Sub End Dim insertNewProcess As String = "INSERT INTO Device_Table(" Dim deviceColumn As String = "DeviceRevision, CustomerName, CustomerCode, CustomerResponsibleEngineer, Date, DevicePartNumber, PackageType" Dim deviceValue As String = ") VALUES ('01', '" + CustNameDropDownList.SelectedValue.ToUpper + "', '" + CustCodeLabel.Text + "', '" + CustomerResponsibleEngineerTextBox.Text.Trim.ToUpper + "', '" + Format(Now, "dd-MMM-yyyy").ToUpper + "', '" + DevicePartNumberTextBox.Text.Trim.ToUpper + "', '" + PackageTypeTextBox.Text.Trim.ToUpper + "'"
I am using a FormView to populate data, then inserting it using a LinqDataSource. The primary key is an autoincrementing identity. I'd like to handle the ItemInserted event to update some other tables, but I cannot find how to get the primary key of the newly inserted record. The insert happens fine, but nothing for the PK.
I realize I can change to using a SPROC, or change to creating the new row and doing the insert myself, but I'd prefer to continue with the LinqDataSource's automatic insert.
from tblData left join tblfacility ON tblData.employee_num = tblfacilit.employee_num left join tblextension ext on tblData.extension = ext.extension
tablExtension has phone number extension in it. If we don't know someones phone extension, we put zero for their extension, now there are tons of people who have zero extension.when I run this query, it returns same name lot of times with different cubeNumber so I get
a ax 1 12 0 a ax 1 13 0 a ax 1 14 0 b bx 2 12 0 b bx 2 13 0 b bx 2 14 0
Both emploee a and employee b extensions are zero in above case. I want both a and b to be displayed only once .Right now it is displaying them so many times with all the cubesNumber that have extension zero.
I have started my new mvc project with entity framework,Must say it is very diffcult to work with entity framework.
"I am trying to create new custom entity in .edmx file,Now i have made one column as Entity key,Which is already entity key another entity set."
"Error 3033: Problem in Mapping Fragment starting at line 3081: EntitySets 'Entityset name' and 'Entityset name' are both mapped to table 'Entityset name'. Their Primary Keys may collide."
