Which is better function or stored procedure?
Stored procedures in SQL are easier to create and functions have a more rigid structure and support less clauses and functionality. By the other hand, you can easily use the function results in T-SQL. We show how to concatenate a function with a string. Manipulating results from a stored procedure is more complex.
What is the difference between a stored function and a stored procedure?
A function has a return type and returns a value. A procedure does not have a return type. But it returns values using the OUT parameters.
Can we use table as parameter to stored procedure?
Table-valued parameters are declared by using user-defined table types. You can use table-valued parameters to send multiple rows of data to a Transact-SQL statement or a routine, such as a stored procedure or function, without creating a temporary table or many parameters.
How do you pass parameters to a table-valued function?
How to pass multiple parameters into an Inline table-valued function
- Creating a user-defined table type: CREATE TYPE ProductNumberList AS TABLE.
- Adding the table-valued to udfGetProductList function with READONLY statement:
- Declare a variable as a table-valued parameter and populate it with multiple parameter values.
Why SP is faster than function?
Stored Procedures can be fast, very fast, as they are pre-compiled. The optimiser does not have to work out the execution plan each time. A Stored Procedure will return results in a table form. Functions can be Scalar (returning a single result) or return Tabular data.
Why is stored procedure faster than query?
Stored procedures are precompiled and optimised, which means that the query engine can execute them more rapidly. By contrast, queries in code must be parsed, compiled, and optimised at runtime.
What is diff between function and procedure?
A function would return the returning value/control to the code or calling function. The procedures perform certain tasks in a particular order on the basis of the given inputs. A procedure, on the other hand, would return the control, but would not return any value to the calling function or the code.
What is table valued function in SQL Server?
What is a table-valued function in SQL Server. A table-valued function is a user-defined function that returns data of a table type. The return type of a table-valued function is a table, therefore, you can use the table-valued function just like you would use a table.
How do you pass a DataTable into a parameter to a stored procedure?

Why stored procedure is better than query?
every query is submited it will be compiled & then executed. where as stored procedure is compiled when it is submitted for the first time & this compiled content is stored in something called procedure cache,for subsequent calls no compilation,just execution & hence better performance than query.
Can a stored procedure return a table?
