hello, win the window (Create New SQL Server Database) is opened there is no thing in the list (Server Name). can you help please.
why mine is so complicated, in order to create a table I need to manually code it but you can casually just add table in there :O I'm using microsoft sql server and if it doesn't open my visual studio database won't connect
what if i dont want to search only on ID but leave ID open and fill in the name?
Sir when iam using update query it's showing database is locked massage is showing plz help me
Simply and easy. Thanks Sir
Most welcome
how do use the sql server in visula studio?
anyone help me
After click on the create new sql server giving the server name and new database name It is showing like create Database permission denied in database 'master'
Create database and insert record. check it's OK or not.
What if i dont want to hardcode DB connection string? I want user to input the DB name, user and password for db user. how do i do that?
Getting error at cmd.executenonquery();
same :[ how to fix it ?
you have error at insert or update or delete query
Check your code using breakpoint... as you can check where error generated.
its a great video really simple thank you, would you be able to upload the validation for not successfully updated because ID is primary key and primary can't be updated.
You can create Unique Key instead of Primary Key to perform update operation.
I kept having invalid column name error for the Id on the UPDATE button command
Thank you.
How do you check if a record already exists during the insert
That's why ID field is made as Primary key. Database cannot contain duplicate Primary key value.
@@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.");
}
I want to search, write the letter of the name, how??????
How to make database like this for mobile
do you have a toturial that can search IDnumber and it will display the picture of the student
Visit this tutorial czcams.com/video/fjftbYysTIE/video.html
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
You just skip the parse command, like he has for '@Name'... since the text box input default is a string.
I am trying to follow your code step-by-step. I keep getting an error when I run it. the con.Open(); is what's causing the error. Any pointers? Thanks!
do u know now what that means
what's u'r server name, if that's backslash in y'r server name try to double it (\\), that was i think, because i have same problem before
If you want to search for something else instead of everything in the database just swap the query with your research query
Everything is well, but the data does not get updated. The table is till empty
I need your help
3:08 I don't have a Server Name to choose from, what should I do?
try with .\sqlexpress
Press View -> SQL Server Object Explorer. In SQL Server part you will see you local server. Select this part and press F2 to select the name. Mine is "(localdb)\MSSQLLocalDB". Enter this name in add connection form and now it would be working.
@@bloodflower thank you so much
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
Executenonquery used to perform insert update and delete operation. Use executenonquery and debug. If you get any error message just reply
ExecuteNonQuerry It is mandatory to use it's check connection string is right or wrong then why yu removing
I am also having the same problem with cmd.ExecuteNonQuerry. Any help please?
Getting exception at con.open();
iska source code provide kar sakty hain?
Sir Can u Share Registration from Bcz I Like ur teaching sir....
Yes, soon
My server names are not loading, What can i do?
Type manually and connect.
Dude, that update code updates all the rows in the table, with the same values. You need to fix that with "where" statement to update only one row.
definitely we should add where clause.
I keep getting exceptions from the Sqlcommand by and execute query. how do I fix this?
Same
@@take_the_trade just found my problem dude haha double check if ur textbox has .text after it
@@andreymanlapig8584 got it ... Thanks
Thanks for your help.
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.
U right
I'm having this issue now. And I have no idea how to get around it.
@@kenballard2039 which problem facing?
Not that hard
The ExecuteNonQuery ... didn't work
Need to improve separate your form in Add, Edit then call to your main form
how can restart service sql
right click on My PC, Click on Manage, click on service in left pane. click on Microsoft SQL Server and restart. Thanks.
there is no data connections in my server explorer..
In server explorer you will get a icon to connect to server. click on the icon and connect to the SQL server. Thanks.
If i put nothing in ID and search it gives error please give the solution of that
Just add code if (IDTextBox.Text !="")
@@SwiftLearn says error : input string was not in a correct format ,
Hi why i cant create new connection?? It has no server name option when i click the dropdown button. I am newbie sir.

Syntax error show - con = Open();
This code 'Open()' 👈 the name 'Open' does not exist in this context.
Solution? ??
In the video at 09:29, there is a small issue with the SQL update method. If there are multiple rows of data, all of the data may be updated.
```
SqlCommand cmd = new SqlCommand("Update StudentInformation set Name=@name, Age=@age, Coures=@coures WHERE id = " + textboxId.Text , conn);
```
I added WHERE. hope it can help you😃
Sure.
Ey I get to be the first dislike! :D
Really! Please suggest me, how to make batter for you. thanks.
when I run the code it said that "System.Data.SqlClient.SqlException: 'Incorrect syntax near the keyword 'Table'.'" in line with cmd.ExecuteNonQuery();
Check your SQL query.
BIG SHIT!
{"Input string was not in a correct format."}
It means you are trying to insert string into int type. check and write accurately.
@@SwiftLearn i do ths same like u in vicdo.
thanks
