![]() ![]() This means the query is optimized along with proper indexing server side. The first execution may take longer while later calls will be shorter. Speed/Optimization: Stored Procedures are cached on the server.Isolation of Business Rules: Having Stored Procedures in one location means that there’s no confusion of having business rules spread over potentially disparate code files in the application.Testing: Can be tested independent of an application.Maintainability: Because scripts are in a single location updates and tracking of dependencies based on schema changes become easier.These advantages are subjective to developers, database administrators, business and/or security requirements. ![]() The following are not all inclusive reasons in regards to advantages of using Stored Procedures. Instead of writing inline SQL and then attempting to manipulate the data from within the code. Of SQL with the iterative and conditional processing control of code development. Stored procedures have been viewed as the de facto standard for applications to access and manipulate database information using codified methods, or “procedures.” This is largely due to what they offer developers: the opportunity to couple the set-based power Stored proceduresĬan receive variables, return results or modify variables and return them, depending on how and where the variable is declared. Stored-procedure flow-control statements typically include IF, WHILE, LOOP, REPEAT, and CASE statements, and more. ![]() May also contain declared variables for processing data and cursors that allow it to loop through multiple rows in a table. Such result sets can be processed using cursors, by other stored procedures, by associating a result-set locator, or by applications. Stored procedures may return result sets (a DataTable for instance), i.e., the results of a SELECT statement. Basic usage, common SQL statements with or without parameters while other uses include data-validation or access-control mechanisms. This article presents basics of Stored Procedures to perform common CRUD operations in a Windows Form solution written in Visual Studio, C# with Microsoft SQL-Server database.Ī stored procedure is a prepared SQL code that you can save, so the code can be reused repeatedly which are stored in a database. ![]()
