The MOD()<\/code> function in SQLite is used to calculate the remainder when one number is divided by another. This operation is commonly known as the modulo operation.<\/p>\n\n\n\n\n\n\n\n

Syntax<\/h2>\n\n\n\n
MOD(numerator, denominator)<\/code><\/pre>\n\n\n\n
Where:<\/p>\n\n\n\n
    \n
  • numerator<\/code><\/em> is the number to be divided.<\/li>\n\n\n\n
  • denominator<\/code><\/em> is the number by which the numerator will be divided.<\/li>\n<\/ul>\n\n\n\n
    The function returns the remainder of the division of the numerator by the denominator. <\/p>\n\n\n\n
    Example 1<\/h2>\n\n\n\n
    Here’s a simple example to demonstrate:<\/p>\n\n\n\n
    SELECT 11 \/ 3,\n       MOD(11, 3);<\/code><\/pre>\n\n\n\n
    Result:<\/p>\n\n\n\n
    +--------+------------+
    | 11 \/ 3 | MOD(11, 3) |
    +--------+------------+
    | 3      | 2.0        |
    +--------+------------+<\/pre>\n\n\n\n
    Here we can see that dividing 11 by 2 equals 3, with a remainder of 2. <\/p>\n\n\n\n
    In other words, 3 multiplied by 3 equals 9, which means we need another 2 in order to get to 11. The 2 part is the “remainder”, which the MOD()<\/code> function returns for us. <\/p>\n\n\n\n
    Example 2<\/h2>\n\n\n\n
    Let’s say we have a table transactions<\/code> with a column amount<\/code>, and we want to find the remainder when the amount<\/code> is divided by 10.<\/p>\n\n\n\n
    -- Create the 'transactions' table\nCREATE TABLE transactions (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    amount INTEGER\n);\n\n-- Insert sample data into the 'transactions' table\nINSERT INTO transactions (amount)\nVALUES\n    (23),\n    (57),\n    (88);<\/code><\/pre>\n\n\n\n
    Now let’s run a query to calculate the remainder when amount<\/code> is divided by 10:<\/p>\n\n\n\n
    SELECT \n       amount, \n       amount \/ 10 AS division_result,\n       MOD(amount, 10) AS remainder\nFROM transactions;<\/code><\/pre>\n\n\n\n
    In this example, for each row in the transactions<\/code> table, SQLite will calculate the remainder of the amount<\/code> when divided by 10 and return it as a new column named remainder<\/code>.<\/p>\n\n\n\n
    Result:<\/p>\n\n\n\n
    +--------+-----------------+-----------+
    | amount | division_result | remainder |
    +--------+-----------------+-----------+
    | 23     | 2               | 3.0       |
    | 57     | 5               | 7.0       |
    | 88     | 8               | 8.0       |
    +--------+-----------------+-----------+<\/pre>\n\n\n\n
    Here, for the first row, 23 divided by 10 leaves a remainder of 3, for the second row, 57 divided by 10 leaves a remainder of 7, and for the third row, 88 divided by 10 leaves a remainder of 8.<\/p>\n\n\n\n
