You can create Unique Key instead of Primary Key to perform update operation.

[@davidwenemoser5857]

what if i dont want to search only on ID but leave ID open and fill in the name?

[@rodrigolnl]

You missed the part about how to run SQL server to begin with, and if someone is looking for CRUD, he is probably newbie and it is a hell of a job to configure the server with visual studio.

[@mizantednioc]

Thank you.
How do you check if a record already exists during the insert

[@chaithravasista1622]

That's why ID field is made as Primary key. Database cannot contain duplicate Primary key value.

[@JeffKastner]

@@chaithravasista1622 But error handling should still be there or the program would crash if someone accidentally entered the wrong value. He would want something quick and easy like so...
try
{
cmd.Parameters.AddWithValue("@ID", int.Parse(textBox1.Text));
}
catch (FormatException)
{
MessageBox.Show("Please enter a whole number.");
}
catch (OverflowException)
{
MessageBox.Show("The number is too big.");

If you want to search for something else instead of everything in the database just swap the query with your research query

[@bishalpoudel3586]

Problem with cmd.ExecuteNonQuerry, someone please help. .. when i remove ExecuteNonQuerry , then it shows it has been inserted but actually in table there is no data updated

[@SwiftLearn]

Executenonquery used to perform insert update and delete operation. Use executenonquery and debug. If you get any error message just reply

[@vijayalaxmipatil6621]

ExecuteNonQuerry It is mandatory to use it's check connection string is right or wrong then why yu removing

[@cyprianfanga.750]

I am also having the same problem with cmd.ExecuteNonQuerry. Any help please?

[@samsantos5670]

how about when you are not using int and you are using string how will you convert int to string so that you will not encounter unhandled exception

[@JeffKastner]

You just skip the parse command, like he has for '@Name'... since the text box input default is a string.
