In various programming languages and database libraries, the function that returns the number of fields (or columns) in a result set is typically called num_fields() or similar. For example, in PHP with MySQLi, you can use $result->field_count to get the number of fields. In Python's SQLite library, you can use len(cursor.description) after executing a query. The exact function or method may vary depending on the database and programming language being used.

What is the difference between a function and expression?
Functions and Expressions are representations of relationships that exist among entities, however a function always returns a value (or result)
What is the output of a function called?
The output of a function refers to the value or result that the function returns after executing its defined operations. This output is often determined by the input parameters passed to the function and the logic contained within it. In programming, the output can take various forms, such as a number, string, list, or even a more complex data structure. Essentially, it represents the end product of the function's processing.
What is f(g(4))?
That means that function "g" is first applied to the number 4. Then, the result of that is used with function "f".
A function takes in values of variable called inputs and gives back values of the variable called outputs?
No. A function takes in values of no, one, or more input variables, and returns no or one result. It cannot return more than one result. Do not confuse this with returning multiple results using call by reference parameters - this is not the same thing.
What is the limitation to the domain of a function?
Any number that produces an undefined result from a function f(x) is not in its domain.For example, the number 0 is not in the domain of f(x) = 1/x, because 1/0 is undefined.Undefined answers will result from any of the following situations:- Dividing by 0- Taking the square root of a negative number- Taking the log (any base) of 0 or any negative number- Taking the log (base 1) of any number
What function returns a result based on a condition?
IF
Which logical function returns a true result only when all its arguments are true?
The AND function.
Difference between subroutine and function?
Both A function and a Sub carry out a procedure, but only A function returns a result while a Sub does not return a result.
What is the vlookup function?
looks up a value and returns a related result from the lookup table.
What takes a value or values performs an operation and returns a result to the cell?
called function
What is the difference between a function and expression?
Functions and Expressions are representations of relationships that exist among entities, however a function always returns a value (or result)
When assigned to a cell the what function returns?
In Excel, when a function is assigned to a cell, it returns a value or result based on the calculations or operations defined within the function. For example, the SUM function will return the total of specified numbers or cell ranges. The output is displayed directly in the cell where the function is entered, and it can change dynamically if the referenced data changes.
What is the round function in excel used for?
ROUND is a function that returns a number rounded to a specified number of digits.Syntax: =ROUND( number, digits )number is the number to rounddigits is the number of digits to round the number toEXAMPLES:=ROUND(1/3,2) will return 0.33=ROUND(1/6,2) will return 0.17
If function does not return value by default it returns python?
If a function in Python does not explicitly return a value using the return statement, it implicitly returns None by default. This means that when you call such a function, the result will be None, indicating that no value was returned. You can check this by assigning the function call to a variable and printing it, which will show None as the output.
Where does the Subtotal command insert a row?
The SUBTOTAL function does not insert a row. It returns the result in the cell where you type the formula. See related links for information about the SUBTOTAL function.
What is a max formula?
The MAX function returns the largest number from the cells you evaluate.EXAMPLE:A1 = 104A2 = 623A3 = 23A4 = 234A5 = 198FORMULA: =MAX(A1,A2,A3, A4, A5) will display a result of 623, because A2 contains the largest number.
