MOD() Function in MySQL. The MOD() function in MySQL is
used to find the remainder of one number divided by another
. The MOD() function returns the remainder of dividend divided by divisor. if the divisor is zero, it returns NULL.
Why do we use MOD function?
The function
helps find a remainder after a number (dividend) is divided by another number (divisor)
. As a financial analyst. Perform financial forecasting, reporting, and operational metrics tracking, analyze financial data, create financial models, the function is useful when we need to process every nth value.
What is the use of MOD function in SQL?
SQL MOD() function is
used to get the remainder from a division
. The SQL DISTINCT command along with the SQL MOD() function is used to retrieve only unique records depending on the specified column or expression.
What is the use of MOD function give an example?
The Excel MOD function
returns the remainder of two numbers after division
. For example, MOD(10,3) = 1. The result of MOD carries the same sign as the divisor.
Is there modulo in SQL?
Introduction to SQL MOD
()
The MOD function in standard query language (SQL) takes two arguments of numeric data type, the first argument as dividend and second argument as divisor and returns the remainder or modulus after performing a division operation or repeated subtraction. … It performs the same function.

How do I get odd rows in SQL?
- To select all the even number records from a table: Select * from table where id % 2 = 0. To select all the odd number records from a table: Select * from table where id % 2 != 0. …
- select * from emp where (rowid,0) in(select rowid,mod(rownum,2) from emp);—even. …
- Even Number of Selection.
How is mod calculated?
- Start by choosing the initial number (before performing the modulo operation). …
- Choose the divisor. …
- Divide one number by the other, rounding down: 250 / 24 = 10 . …
- Multiply the divisor by the quotient. …
- Subtract this number from your initial number (dividend).
What is mod () function?
The MOD function takes as
arguments two real number operands, and returns the remainder from integer division of the integer part
of the first argument (the dividend) by the integer part of the second argument (the divisor). The value returned is an INT data type (or INT8 for remainders outside the range of INT).
What is the mod symbol?

How do you solve a MOD function?
Modulus function is denoted as y = |x| or
f(x) = |x|
, where f: R → R and x ∈ R. |x| is the modulus of x, where x is a real number. If x is non-negative then f(x) will be of the same value x. If x is negative, then f(x) will be the magnitude of x, that is, f(x) = -x if x is negative.
What is mod in math?
The modulo (or “modulus” or “mod”) is
the remainder after dividing one number by another
. Example: 100 mod 9 equals 1. Because 100/9 = 11 with a remainder of 1.
How do you do fast exponents?
- Step 1: Divide B into powers of 2 by writing it in binary. Start at the rightmost digit, let k=0 and for each digit: …
- Step 2: Calculate mod C of the powers of two ≤ B. 5^1 mod 19 = 5. …
- Step 3: Use modular multiplication properties to combine the calculated mod C values.
What does order by 1 do in SQL?
it simply means
sorting the view or table by 1st column of query’s result
