SQL MOD() function with distinct

Sample table: customer


To get unique remainder of a division of 'receive_amt' by 'grade' from the 'customer' table, the following SQL statement can be used :

SELECT DISTINCT(MOD(receive_amt,grade)) 
FROM customer;

Output:

(MOD(RECEIVE_AMT,GRADE))
------------------------
                       1
                       2

SQL MOD() function with where

Sample table: customer


To get data of 'cust_name', 'opening_amt', 'receive_amt' and remainder of the division of 'opening_amt' by 'receive_amt' from the 'customer' table with following conditions -

1. 'opening_amt' must be more than 'receive_amt',

2. remainder of the division of 'opening_amt' by 'receive_amt' must be more than or equal to 1000,

the following SQL statement can be used :

SELECT cust_name,opening_amt,receive_amt, 
MOD(opening_amt,receive_amt) 
FROM customer 
WHERE opening_amt>receive_amt 
AND MOD(opening_amt,receive_amt)>= 1000;

Output:

CUST_NAME                                OPENING_AMT RECEIVE_AMT MOD(OPENING_AMT,RECEIVE_AMT)
