Inserting A Record Into The Database ..problem With Primary Key..
Sep 7, 2006
hii
I have to insert some data into a table from the webpage. For that I need to know the last occurred value in the primary key and increment this by one and then insert the new record into the table. I am working with SQL Server 2005. I am coding in VB and ASP.NET 2.0. How will I go about this?? Is there some easy way for me to knw the last value of the primary key n then insert the record. It would be great if I get the idea more clear with the help of some code...
Hi, Can someone please tell me the best practices for checking the primary key field before inserting a record into my database? As an example I have created an asp.net page using VB with an SQL server database. The web page will just insert two fields into a table (Name & Surname into the Names table). The primary key or the Names table is "Name". When I click the Submit button I would like to check to ensure there is not a duplicate primary key. If there is return a user friendly message i.e. A record already exisits, if there no duplicate, add the record. I guess I could use try, catch within the .APSX page or would a stored procedure be better? Thanks Brett
hey everyone,I have created two tables in an sql server database. I have a check box in the table 1, and when it is checked, I want to insert that particular record into table 2. (By the way I am using a datagrid) The problem is when I click the check on the particular record I want inserted, and click update, the system copies the record twice instead of once. When I look into table 2, I end up having two of the same records. Can anyone help me.
Hi, Can anybody help me with this, I've got a simple program to add a new record to a table (2 items ID - Integer and Program - String) that matches all examples I can find, but when I run it I get the error : Must declare the scalar variable "@BookMarkArrayA". when it reaches the .insert command, I've tried using a local variable temp in place of the array element and .ToString , but still get the same error This is the code : Public Sub NewCustomer() Dim temp As String = " " Dim ID As Integer = 1 'Restore the array from the view state BookMarkArrayA = Me.ViewState("BookMarkArrayA")
temp = BookMarkArrayA(6) Dim Customer As SqlDataSource = New SqlDataSource()
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.

I am simply trying to use SQLCommand in .net to insert a record into a SQL Server 2005 table. There are 2 fields being pulled from a user input for that could have no values selected. In this case I want to insert a null value into the record. I get an error that Null is no longer supported and that I should use System.DBNull, but that can't be used as an expression. How do I do this? Thank you in advance.
Hi All, i am new to programming, in my application i want to insert a record in sql server database using Ado.net for that i used SqlConnection cn=new SqlConnection(ConfigurationManager.ConnectionStrings["constring"].ConnectionString); SqlCommand cmd; protected void btnInsert_Click(object sender, EventArgs e) { try { cmd = new SqlCommand("Insert into DeptInfo(deptid,deptname)values(" + TextBox1.Text + ",'" + TextBox2.Text + "')", cn); SqlDataAdapter da = new SqlDataAdapter(cmd); cn.Open(); cmd.ExecuteNonQuery(); cn.Close(); TextBox1.Text = ""; TextBox2.Text = ""; } catch(Exception ex) { }} But my requirement is when ever the Insert command is successfull it has to display some alert message(using java script) saying "RECORD INSERTED SUCCESSFULLY" if Record insertion fails it should display some alert message "INSERTING NEW RECORD FAILED" . Any help will be greatly appreciated Thanks,Vision.
i am running a query from one of my asp.net pages. I then want the results which will be around 20 - 30 records to be inserted to a new table. How do I do this?
I get the records from my query but how would i insert more than one record to a new table?
Is it possible to have sql server automatically record date and time (in a designated field)when a record is created in the db? This may seam basic but it has caused me a lot of grief.
Ok I know this might not be the most accurate place to post this but I know someone here has an answer for me on it.I need to get the product_ID of the new record that is created by this insert statement INSERTINTO products ( class_ID,category_ID,product_name,product_desc,product_image,product_dimension,product_o1,product_o2,product_o3,product_ac,product_ph,product_photo ) SELECT class_ID,category_ID,product_name,product_desc,product_image,product_dimension,product_o1,product_o2,product_o3,product_ac,product_ph,product_photo FROM productsWHERE product_ID = @productID
Hi I have a table in sql server with a numeric field as Primary Key. When i insert a new record i need that primary key increments automatic (like access auto increment) because i want avoid the possibility of duplicate Primary Keys. Is that possible? Thank you
I'm performing an insert on a table that has a relationship, but I also want to update the other table that has a foreign key relationship. How do I go about this? Thanks :)
I can't seem to get this work. I'm using SQL2005 I want to check if a record exists before entering it. I just can't figure out how to check it before hand. Thanks in advance.

Is there a way to test the integrity of a record which is about to be inserted in a database before doing so? The goal is to prevent all kinds of runtime errors that will occur after the insertion, if the record breaks any of the database rules. The solution should apply to a VBScript used inside a DTS package.
SELECTIndustry, 100.0 * SUM(CASE when ceoischairman = 'yes' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [YesPercent], 100.0 * SUM(CASE when ceoischairman = 'no' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [NoPercent] FROMTCompanies GROUP BYIndustry ORDER BYIndustry
This code above is working as I need it but I need to insert some additional functionality. Thanks
I need to add something like this:
IF YesPercent > NoPercent UPDATE tableX SET CEOIsChairman='Yes' WHERE Industry='<the industry value being evaluated>' Else If NoPercent > YesPercent UPDATE tableX SET CEOIsChairman='No' WHERE Industry='<the industry value being evaluated>' Else UPDATE tableX SET CEOIsChairman='Equal' WHERE Industry='<the industry value being evaluated>' End
I'm using Microsoft SQL Server Management Studio with SQL Server 2005 (SP2).
I have not had much experience with t-SQL and iterative logic implementation through SQL, therefore I think my problem is fairly basic for most of the pros here.
Here it goes...
I have two tables at hand, TestTab1 and TestTab2.
TestTab1 contains two attributes (columns) namely account_name (nvarchar(50)) and entry_count (int). For all rows in TestTab1, account_name is unique, i.e. for each account_name there is only 1 row in TestTab1. This is my source table.
TestTab2 contains one attribute namely account_name (nvarchar(50)). This table is empty and is my destination table.
I need to insert X entries (rows) for each account_name into TestTab2 where X is the int value in entry_count againt each account_name in TestTab1.
In other words, I need to insert account_name into TestTab2 as many times as the number in entry_count indicates.
I tried reading through the documentation but the help was not friendly enough for me to understand how to implement this.
How do i insert a carriage return at the end of an record that's being sent to a flat file? Currently, I get one long string, and would like for SSIS to put carriage returns at the end of each line.
,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code 54, a, 00345 54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?

Hi,As I wrote my message the solution came to me, so I thought I wouldpost anyway for others to see in case it was useful:Here is some sample DDL for this question:CREATE TABLE Source (my_value INT NOT NULL )GOINSERT INTO Source VALUES (1)INSERT INTO Source VALUES (2)INSERT INTO Source VALUES (3)GOCREATE TABLE Destination (value_type VARCHAR(10) NOT NULL,value INT )GOI would like to fill the destination with a row for the COUNT, SUM,MIN, and MAX. My own problem is of course much more complex than this,but this is the basic stumbling block for me now. So, the rows that Iwould expect to see in Destination are:value_type value---------- -----COUNT 3SUM 6MIN 1MAX 3The solution that I came up with was to add a Value_Types table:CREATE TABLE Value_Types (value_type VARCHAR(10) NOT NULL )GOINSERT INTO Value_Types VALUES ('COUNT')INSERT INTO Value_Types VALUES ('SUM')INSERT INTO Value_Types VALUES ('MAX')INSERT INTO Value_Types VALUES ('MIN')GONow the SQL is pretty simple:SELECT V.value_type,CASE V.value_typeWHEN 'COUNT' THEN COUNT(*)WHEN 'SUM' THEN SUM(S.my_value)WHEN 'MAX' THEN MAX(S.my_value)WHEN 'MIN' THEN MIN(S.my_value)ENDFROM Source SINNER JOIN Value_Types V ON 1=1-Tom.P.S. - I know that I did not include primary or foreign keys in my DDL.I'll leave it as an excercise to the reader to figure those out. Ithink the code adequately explains the concept.
Hello, I'm trying to accomplish 3 things with one stored procedure.I'm trying to search for a record in table X, use the outcome of thatsearch to insert another record in table Y and then exec another storedprocedure and use the outcome of that stored procedure to update therecord in table Y.I have this stored procedure (stA)CREATE PROCEDURE procstA (@SSNum varchar(9) = NULL)ASSET NOCOUNT ONSELECT OType, Status, SSN, FName, LNameFROM CustomersWHERE (OType = 'D') AND (Status = 'Completed') AND (SSN = @SSNum)GO.Then, I need to create a new record in another table (Y) using the SSN,FName and Lname fields from this stored procedure.After doing so, I need to run the second stored procedure (stB) Here itis:CREATE PROCEDURE procstB( @SSNum varchar(9) = NULL)ASSET NOCOUNT ON-- select the recordSELECT OrderID, OrderDate, SSNFROM OrdersGROUP BY OrderID, OrderDate, SSNHAVING (ProductType = 'VVSS') AND (MIN(SSN) = @SSNum)GO.After running this, I need to update the record I created a moment agoin table Y with the OrderDate and OrderID from the second storedprocedure.Do you guys think that it can be done within a single stored procedure?Like for example, at the end of store procedure A creating an insertstatement for the new record, and then placing something like execprocstB 'SSN value'? to run stored procedure B and then having aupdate statement to update that new record?Thanks for all your help.
A user inadvertantly deleted a record in a table that maintains an identity seed. I attempted to insert the record using SET IDENTITY_INSERT ON, but forgot that this table is an article in merge replication. I am attempting the insert on the publisher and I get the following message:
Msg 548, Level 16, State 2, Line 2
The insert failed. It conflicted with an identity range check constraint in database 'cad', replicated table 'dbo.emmain', column 'empl_id'. If the identity column is automatically managed by replication, update the range as follows: for the Publisher, execute sp_adjustpublisheridentityrange; for the Subscriber, run the Distribution Agent or the Merge Agent.
The statement has been terminated.
How can I re-insert this record??Thanks in advance for any help
Can someone explain what happens when two users concurrently attempt tocreate a new record in a table with an autonumber primary key? For example,user 1 creates a new record and manipulates it within a transaction makinguse (perhaps) of the @@IDENTITY value when creating other, related records.Before this transaction is complete, user 2 creates a new record and doesthe same thing. Presumably they will both have the same @@IDENTITY? Ifthis is the case, how is it possible to manage such a situation?Thanks.
I am duplicating a record from my asp.net page in to the database. When i click on save I am getting the following error message Violation of PRIMARY KEY constraint 'PK_clientinfo'. Cannot insert duplicate key in object 'clientinfo'. The statement has been terminated. The above message i am getting since i have tried to duplicate the clientname field of my table which is set as the primary key. What i want is instead of this message in the browser i need to display an alert saying "the clientname entered already exists" by checking the value from the database. Here is my code. pls modify it to achieve the said problem if(Page.IsValid==true) { conn.Open(); SqlCommand cmd = new SqlCommand("insert into clientinfo (client_name, address) values ('"+txtclientname.Text+"', '"+txtaddress.Text+"')", conn); cmd.ExecuteNonQuery(); conn.Close(); BindData(); txtclear(); System.Web.HttpContext.Current.Response.Write("<script>alert('New Record Added!');</script>"); Response.Redirect("Clientinfo.aspx"); }

Hi, All:Please help. I use sql server as back end and Access 2003 as front end(everything is DAO).A table on SQL server has an identity column as the key.We have trouble on adding records to this table using the following SQL.strSQL = "INSERT INTO myTableOnSQLServer (A, B, C, D, E) SELECT A, B, C, D,E FROM myTableonAccessLocal"db.execute strSQLThe schema of the table "myTableOnSQLServer" and the schema of the table"myTableonAccessLocal" are all the same except that the "myTableOnSQLServer"has an identity column (ID). The key of the "myTableOnSQLServer" is "ID" andthe table "myTableonAccessLocal" does not have a key.When we try to run the query, it gives errors indicating the key is violatedor missing.Should I figure out the autonumber for it first and then add to the SQLserver table?Many thanks,HS
Please help me somebody solve my problem with my first :o trigger: ALTER TRIGGER partner_update ON dbo.partner FOR UPDATE AS INSERT INTO partner (name) SELECT name FROM deleted UPDATE invoice SET id_partner= *** WHERE id_partner = (SELECT id_partner FROM deleted) *** - here I want to add a "reference" to the newly added record's automatically generated primary key (not to the updated!) Is it possible?
