Three methods for randomly generating data and three methods for generating data

1. Generate a random number using the Tree Structure
Select 1090900 + round (rownum/2 ),
Round (dbms_random.value (100000,10001000), 0)
From dual
Connect by rownum< 100

2. Generate a random number through Cartesian Product
Select rownum
From all_obj_colattrs,
All_obj_colattrs;

3. generate random numbers using tools
TOOLS ---> DATA GENERATOR

How to automatically generate random data in excel

To see what data you want, a RAND () function can generate data randomly.

RAND

Returns a random number with an even distribution greater than or equal to 0 and less than 1. A new value is returned for each worksheet calculation.

Syntax

RAND ()

Description

To generate a random real number between a and B, use:
RAND () * (B-a) +

If you want to use the RAND function to generate a random number that does not change with cell computing, you can enter "= RAND ()" in the editing column to maintain the editing status, and then press F9, change the formula permanently to a random number.
Example

= RAND () a random number (variable) between 0 and 1)
= RAND () * a random number (variable) with a value greater than or equal to 0 but less than 100)

How to randomly generate data with a specified range in excel

To generate a random number, you must use the rand function and the RANDBETWEEN function. The former generates a function smaller than 1, and the latter generates a function between two constrained numbers. However, the RANDBETWEEN function must install the function library, the default installation is not necessarily available. So I will introduce the rand function as an application. Follow these steps:
Input = RAND () * (60.019-60) + 60 in A1-E1
Input = RAND () * (60.019-60) + 60 in A2-E2

The rand function generates a random number between 0 and 1, so that it can multiply the number of ranges and add the base number to obtain the random number between the ranges you want.
