In the database one number like a 91-9685748596 and, 2nd number like 9122-9685748596 and another one is 9685748596 .when we are try to formate it using substring function it all are may be9685748596,9685748596,9685748596.Mobile number is assigned as a primary key.so its showing error "Primary key violation".We can not the remove primary key also and there are 50 lack data in our database.

="it.TRANSACTION_ID
LIKE '%' + @SearchID + '%'"
It tells me LIKE must be of string type. What can I do?
i have created a web form, where i have 3 textboxes into a table and one submit button.
i would like to store values from the textboxes into my database (sql server) when i click the submit button.
but how to insert the value that is not in textbox into database which is primary key for table without identity column.
I have tables:
MAILBOX
MailboxId int PK
MailboxTypeId int FK
MAILBOXTYPES
MailboxTypeId int PK
I can't make relationship between MailboxTypeId in table MAILBOXTYPES and MailboxTypeId in table MAILBOX why ?
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.
tbl_table1
ID primarykey (autoinc)
UserId uniqueidentifier
IdNumber primarykey int
I'd like to have a relationship between two tables.
I have a table with primary key whose importance is technically high and none business wise. So, when I display the table data to user, I would like not to show him the primary key. Even if I load it in sqldatasource and dont show (I did this by removing the cloumn in "Columns" tag of GridView), I am not able to update or delete row using the built-in UpdateCommand & DeleteCommand. I have created the delete paramters but it does nothing when I hit the delete button.How to get around it?

If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
View 1 Repliesi get the following exception (missing primary key) in the line of using Find() method "Table doesn't have a primary key." I've rechecked the Database and all Primary Key columns are set correctly.
DataTable dt = p.GetAllPhotos(int.Parse(Id));
DataTable temp = new DataTable();
temp = dt.Clone();
temp = (DataTable)(Session["currentImage"]);
DataTable dtvalid = new DataTable();
dtvalid = dt.Clone();
DataRow[] drr = new DataRow[1];
drr[0] = dt.Rows.Find((int.Parse(temp.Rows[0]["photoId"].ToString()))+1);
foreach (DataRow dr in drr)
{
dtvalid.ImportRow(dr);
}
dtvalid.AcceptChanges();'
