ADO.NET is the core data access technology for .NET languages. I will assume that the reader is familiar with creating .NET applications using Visual Studio. Identifying C# source files containing database access statements (ADO.NET references and dynamic SQL) In a typical database-driven application, you may have up to 10-20% of files containing database related code (except batch processing utilities that may contain SQL code in every file). I tend to wrap the SqlCommand with a Using() also but noticed you hadn't... Good catch on the missing close. Here is the code to call the AddCustomer stored procedure:". hello ! Take a look at the. When you write ADO.NET code to access a database, you need a connection string to specify the database that you want to access. Updated classes as per Erik's suggestion. the number of rows inserted, update or deleted by the command, The SqlConnection and SqlCommand objects are wrapped with a "using" statement which ensures that the objects are disposed; the caller is not responsible for "freeing" these objects. ExecuteQuery not returning any rows. Copyright (c) 2006-2020 Edgewood Solutions, LLC All rights reserved The following code listings demonstrate how to retrieve data from a database using ADO.NET data providers. I can say from testing that if not explicitly closed, then the next open connection will open a new connection, not reuse the previous one. Developing applications for SQL Server usually results in a variety of access methods that the programmers use. As I see it I need two methods in the class: one that executes a stored procedure that returns a result set and another that executes a stored procedure that does an insert, update or a delete. Note that ADO.Net does keep closed connections around for awhile, to reuse for connection pooling. The ADO.NET classes are found in System.Data.dll. This is helper class I have written to retrieve data and execute CRUD operation on sql server database either using queries or stored procedures. Use the Microsoft.Data.SqlClient namespace to access SQL Server, or providers from other suppliers to access their stores. Most of these classes map closely to basic data access concepts such as the Connection to the database, a Query, and QueryResults.
