Get Primary Key Of Last Inserted Record
Oct 1, 2007Ok 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

Jan 4, 2005I need to insert a row of data and return the value of the primary key id of the row.
I thought that something like this would work
int Key = (int)command.ExecuteScalar();
where command is SqlCommand object.
It doesn't work, maybe I've misunderstood the usage of ExecuteScalar.
Setting Primary Key Of New Row Being Inserted
Sep 21, 2006Not sure if this is the right place for this post or not, but I'll give it a try...
If I am inserting a record into a table that uses a Primary Key, but not an Identity column, how do I insert the new primary key value? I started out with SQL just letting the Identity column increment itself for primary keys, but I cannot do that for this particular situation.
If 'AddressID' is the primary key in the 'Address' table, could I do something like this:
INSERT INTO Address (AddressID, Field1, Field2, ...)
VALUES (**max value of primary key in Address table, plus 1**, 'field1data', 'field2data', ...);
If that works, how would I make this part of the insert query:
**max value of primary key in Address table, plus 1** ?
I hope this question is clear and makes sense. If it's not, please let me know.
How To Prevent A Second Entry Being Inserted With Primary Key Value? (C#)
Jan 16, 2008Ok, this is a really stupid question, but I can't seem to find an answer I understand. In my SQL database I have a a table called MasterSkillList, to which the user can write by using a little web form with a text box and a drop down list. The table has 2 fields, Skill and Attribute. Skill is the primary key, as no skill can appear twice. What I want to do is prevent just that, I don't want people to enter the same skill more than once. So how do I tell the user that the entry allready exists in the database?
My C# Code is as follows:1 protected void btnSubmit_Click(object sender, EventArgs e)
2 {
3 srcAddSkill.InsertParameters["Skill"].DefaultValue = txtSkillName.Text;
4 srcAddSkill.InsertParameters["Attribute"].DefaultValue = ddlAbility.SelectedValue;
5 try
6 {
7 srcAddSkill.Insert();
8 lblErrorMessage.Text = "The skill '" + txtSkillName.Text + "' has been added. It is based on a character's " + ddlAbility.SelectedItem + " score.";
9 lblErrorMessage.Visible = true;
10 txtSkillName.Text = "";
11 }
12 catch (Exception ex)
13 {
14 lblErrorMessage.Text = "An exception has occurred. " + ex.Message;
15 lblErrorMessage.Visible = true;
16 }

How To Read Just Inserted Auto Incremented Primary Key To Use It As Parameter?
Feb 22, 2007Hi. After inserting data (new row) by using DetailsView control, how to read auto incremented primary key (identity) of this new row from sql database to use it as parameter passed to stored procedure?
View 4 Replies View RelatedInserted Records Missing In Sql Table Yet Tables' Primary Key Field Has Been Incremented.
Jun 18, 2007I have a sql sever 2005 express table with an automatically incremented primary key field. I use a Detailsview to insert new records and on the Detailsview itemInserted event, i send out automated notification emails.
I then received two automated emails(indicating two records have been inserted) but looking at the database, the records are not there. Whats confusing me is that even the tables primary key field had been incremented by two, an indication that indeed the two records should actually be in table. Recovering these records is not abig deal because i can re-enter them but iam wondering what the possible cause is. How come the id field was even incremented and the records are not there yet iam 100% sure no one deleted them. Its only me who can delete a record.
And then how come i insert new records now and they are all there in the database but now with two id numbers for those missing records skipped. Its not crucial data but for my learning, i feel i deserve understanding why it happened because next time, it might be costly.

SqlCommand Parameters.Add
Mar 12, 2008Using SqlCommand, this is how I am updating a database table:
Sub UpdateDataGrid(obj As Object, ea As DataGridCommandEventArgs) strSQL = "UPDATE Basket SET Quantity = Qty, Total = TotAmt WHERE BasketID = BID AND ProductID = PID" sqlCmd = New SqlCommand(strSQL, sqlConn) With sqlCmd .Parameters.Add("Qty", SqlDbType.Int).Value = CInt(iQty) .Parameters.Add("TotAmt", SqlDbType.Money).Value = CInt(iQty) * CType(ea.Item.FindControl("lblPrice"), Label).Text .Parameters.Add("BID", SqlDbType.VarChar, 50).Value = strBasketID .Parameters.Add("PID", SqlDbType.VarChar, 50).Value = CType(ea.Item.FindControl("lblID"), Label).Text End With sqlConn.Open() sqlCmd.ExecuteNonQuery() sqlConn.Close()End Sub
But the above code generates the following error pointing to the red colored line in the above code:
Invalid column name 'BID'.Invalid column name 'PID'.
BID & PID are not the column names in the actual database table but can't it be done in the way I have done above? In fact, Qty & TotAmt are not the column names in the actual database table as well; so why isn't the error pointing to Qty & TotAmt as they will be evaluated before BID & PID, if I am not mistaken?

In the event handling procedure, I cast the sender arg. to an SQLCommand object & try to extract the value of the output parameter.
