Understanding how SQL Server version handle security for user impersonation is important when you use BULK INSERT or OPENROWSET. This arrangement is known as impersonation or delegation.
SQL SERVER SOURCE CODE VB NET 2010 INSERT INTO WINDOWS
SQL Server and Microsoft Windows can be configured to enable an instance of SQL Server to connect to another instance of SQL Server by forwarding the credentials of an authenticated Windows user. The user does not have to grant file-access permission to the SQL Server process.
With access to the data file, the user can import data from the file into a table even if the SQL Server process does not have permission to access the file. For the user to be able to use BULK INSERT or OPENROWSET to import data from a data file into a SQL Server table, the user account requires read access to the data file. In contrast, if a SQL Server user logs on by using Windows Authentication, the user can read only those files that can be accessed by the user account, regardless of the security profile of the SQL Server process.įor example, consider a user who logged in to an instance of SQL Server by using Windows Authentication. To successfully read the source data you must grant the account used by the SQL Server Database Engine, access to the source data. Therefore, when a BULK INSERT command is initiated by a login using SQL Server authentication, the connection to the data is made using the security context of the SQL Server process account (the account used by the SQL Server Database Engine service). A login using SQL Server authentication cannot be authenticated outside of the Database Engine. If a user uses a SQL Server login, the security profile of the SQL Server process account is used.
Can anyone please let me know where do i have to use the textbox Id's and also the column names of the database. All i could find was a code for ADO.Net.Īnd this is where i believe i need help with. I need this help in VB. I looked it up on internet but could not find many related to VB. However i do not know what do i have to add in theĪspx.vb page for inserting data into the table. I am using Visual Web Developer and using the same i have dragged a sqldatasource onto my aspx page and also set up the connection.
Once the user clicks on submit, these fields' data should be inserted into the Sql server tables. I just started learning ASP.Net using visual basic and trying to insert data into the SQL Server database using forms, but facing hiccups.
