![]() ![]() The primary purpose of a tabular function is an alternative of view, yet as an add-on with function is that the user can write the logic in the function with the help of a temp table and table variable for more data processing where a view isn’t. The following structure difference between a procedure and tabular function is that function must be required to mention RETURNS with the output type, and it ends with the RETURN keyword that is not needed for the SQL Server procedure. But the restriction with the function is that function cannot performs any ALTER, INSERT, UPDATE or DELETE operation on the table except temp and variable tables. A procedure and function both can be defined with parameters and return the result set with data manipulation with multiple tables as required. Ideally, tabular function and procedure are similar in terms of data fetching result set only. ![]() User-defined functions can be defined by two types scalar function and tabular values function. The essential two types of SQL Server functions are user-defined function and system-defined function. Let’s talk about different types of functions in SQL Server. That should be the essential reason behind allowing the execution of a SQL Server procedure inside the function. The procedure is allowed to play with the database and its property, whether a user-defined function isn’t. A common understanding of the database developer is that the procedure cannot be utilized or executed inside a user-defined function because the user-defined function does not allow performing DML operation with the table. In this article, we will ensure that the execution of the SQL Server procedure inside the function is possible. ![]()
