The result obtained is called the quotient. What is happening here? The division operator only handles the integer part of the result when dividing two integers. When executed in SQL Server or PostgreSQL, the result of this query is 1, while most users would expect 1.5. Let’s bring up that previous example again: You will have to remember certain rules when dividing numbers that do not divide to an integer. However, for SQL Server and PostgreSQL users, the integer division is more complex. MySQL and Oracle users can expect to see the real number to be shown with the data type being float, e.g., 3 / 2 = 1.5. The integer divisions may behave differently depending on your choice of SQL database management system. Let’s clear this up in the next section! How Are Integers Divided in SQL?

Depending on the variant of SQL you are using, the division operator may handle the integer division differently. Isn’t 3 / 2 = 1.5?! The result shown by SQL Server shows a value of 1. The results look like what we would expect, except for the final row.

Let’s run this query and observe the results: quantity With this query, we are selecting the quantity column then showing the result of dividing the quantity value in our result column which contains the result of quantity / 2. SELECT quantity, quantity / 2 AS 'result' Let’s apply the division operator to an entire column of our table and witness its effect. We will use a table called stock, containing typical food items along with their price and quantity. However, it is more likely that you will be working with integers that reside in columns as part of your database tables. You can execute this query, and it will output the result – in this case, 5. The simplest example of the division operator is: It is an efficient and fun method for sharpening your SQL skills. If these expressions cause you any confusion, consider this SQL Practice track from. This means you can use the SQL division operator with: The division operator can be used anywhere there is an expression. Note the inclusion of the WHERE clause is entirely optional. The syntax for the division operator in SQL is as follows: This article will focus on the division operator, discussing the rules that must be followed along with some common mistakes to look out for when trying to divide in SQL. The arithmetic operators are addition ( +), subtraction ( -), multiplication ( *), division ( /), and modulus ( %). The division operator in SQL is considered an arithmetic operator.

This article will show you exactly how to use it and common mistakes to avoid along the way. We have no remainder.The division operator in SQL is used to divide one expression or number by another. My remainder here- noticeĢ94 is less than 298. Times as 4 goes into the 30, so it's going to be roughly 7. Something larger than 42, then you also made a mistake,Īnd you have to adjust upwards. Three times, you do 3 times 42, you get some number here. Times, and you do 9 times 42 and you get a number larger thanĢ98, then you overestimated. You make a mistake is, if say it goes into it 9

And sometimes it might involveĪ little bit of trial and error. Where the art happens when we're dividing byĪ multi-digit number right over here. And so 11 minus 2 isĩ, and 6 minus 4 is 2. To the ones place, and then that becomes an 11. So let's take a 10 from theħ0, so that it becomes a 60, and give that 10 So 71 minus 42 would beĢ9, but we could also do it by regrouping. Minus 42 in your head, knowing, hey, 72 minus 42 would be 30. The side for a little bit and focus on the process. But what we're really saying,Ĥ2 goes into 7,100 100 times because we're putting this The process where you say, hey, 42 goes into 71 one time. Times does 42 go into 7? Well, it doesn't reallyĭoes 42 go into 71? Well, it goes into 71 one time. Number, not a one-digit number, but the same idea holds. Here is we're now dividing by a two-digit
