I want to use a variable in he querry.
can i use it like...

select * from students where name='textbox.text' ......????

if not then please help how to use a variable that may contain a value at run time and can we use that variable in the querry??

for instance. when i type the word "rahul" in the textbox i want to run a
query like " Select * from customers WHERE name = textbox.Text "

I do not know how to use the textbox name in the query, I think this should
lead me to the solution on finding names.

Sql server doesn't know what textbox.text means. So you have to make use of ADO.NET to talk to sql server from .NET.

Tons of Articles available out there on Google regarding the same. Try to search.

Solution 1

You can pass command parameters - SqlCommand.Parameters Property [^]. Command parameters are used to pass data from input fields into a query that executes on the back end.
