Multi statement table-valued UDF can add flexibility to T-SQL solutions, but using an inline UDF is almost always more efficient. Table-valued UDF that returns table result set can be multi statement and inline. Table-valued user defined function (UDF) allows encapsulating rich T-SQL logic that returns a result set, and using that result set anywhere that a real table is allowed.
#APEX SQL VS SQL PROMPT CODE#
Type the T-SQL code in the query editor and from the ApexSQL Refactor menu choose the Encapsulate code as option and the Scalar Inline Function option from the submenu:Įncapsulate code as an inline table function A query that embeds the original expression inline uses such would run faster than a query that invokes the function, because when invoking a scalar UDF as part of a query, and pass the function a column from the table as input, the function is invoked for each row. User defined functions (UDFs) give a great benefits in terms of encapsulation and code reusability. Encapsulate code as an inline scalar function usp_City addition to the Encapsulate code as a store procedure option, ApexSQL Refactor offers more options for encapsulating code. If the user chooses the Replace with reference to new stored procedure option the generated CREATE PROCEDURE script will be opened in a new query window, and the source code will be replaced with the EXEC statement in the query window from which the code was selected:ĮXECUTE dbo. The Replace with reference to new stored procedure option replaces the selected source code in the query window with the EXEC statement. If the chosen option is Do not replace, the generated CREATE PROCEDURE script will be opened in a new query window, and the source code will remain in the query window from which is selected. In the next dialog user can choose whether to replace the source SQL code. To implement this feature, select the code in the query window.įrom the SQL Prompt menu, choose the Encapsulate as a new store procedure option.
In RedGate® SQL Prompt, Encapsulate as a new stored procedure is the only feature for encapsulating code. It takes less time to process the procedure since the query processor does not have to create a new plan.
A procedure compiles the first time it is executed and creates an execution plan that is reused for following executions. RedGate® SQL Prompt – The Encapsulate as a new stored procedure optionĪ stored procedure is SQL code written only once and is maintained in a single instance that can be called from several different applications. In this article the comparison of refactoring options offered in ApexSQL Refactor and RedGate® SQL Prompt will be shown.

The process of database refactoring defines how to safely evolve a database schema in small steps
Database refactoring is a simple database transformation which improves its design without changing the behavioral semantics of the database.
