For more complex processes, especially those involving large transformations, slowly changing dimensions, data mining lookups, etc., SSIS has three advantages. First, it manages memory very efficiently, which can result in big performance improvements over TSQL alone. 17
Why are we using a stored procedure instead of a function?
When you call the stored procedure, you must specify that it is an external parameter. An advantage of stored procedures is that you can have multiple parameters, while in functions you can return a single variable (scalar function) or a table (table functions).
What are the benefits of using stored procedures?
A stored procedure is an important tool for working with databases. Allowing greater flexibility than SQL statements, ETL developers and programmers use stored procedures for various tasks within databases.
Why did we use a stored procedure in our ETL application?
When you call the stored procedure, you must specify that it is an external parameter. An advantage of stored procedures is that you can have multiple parameters, while in functions you can return a single variable (scalar function) or a table (table functions).
What is the best function or stored procedure?
Stored procedures in SQL are easier to create, and functions have a more rigid structure and support fewer clauses and functions. On the other hand, you can easily use the function results in TSQL. We show how to concatenate a function with a string. Manipulating the results of a stored procedure is more complex.
Why are we using a stored procedure instead of a query?
Instead of an SQL query, a stored procedure is called as a function call. Stored procedures can have parameters to pass values into the procedure and return values from the call. Results can be returned as a result set or as an OUT parameter cursor.
When would you use a function instead of a stored procedure?
The advantages of a udf over an sps: The procedure allows both SELECT and the DML statement (INSERT/UPDATE/DELETE), while Function only allows the SELECT statement. Procedures cannot be used in a SELECT statement, while functions can be embedded in a SELECT statement.
What is the difference between a function and a stored procedure?
The function must return a value, but this is optional in the stored procedure. A procedure can also return zero or n values. Functions can only have input parameters, while procedures can have either input or output parameters. Functions can be called from a procedure, while procedures cannot be called from a function.
What are the benefits of using stored procedures?
A stored procedure can be used like modular programming, which means that it is created once, stored, and called many times as needed. This supports faster execution. It also reduces network traffic and offers better data security.
What is a stored procedure and what are its advantages and disadvantages?
A stored procedure is a precompiled collection of SQL statements and SQL command logic stored in the database. The main purpose of the stored procedure is to hide direct SQL queries from the code and improve the performance of database operations like SELECT, UPDATE, and DELETE.
