How do I get two decimal places in SQL?
Below are four functions that can be used to format a number to two decimal places in SQL Server.
- The CAST() Function. The most obvious way to do it is to convert the number to a decimal type.
- The CONVERT() Function.
- The FORMAT() Function.
- The STR() Function.
What is relational division in SQL?
Relational division is used in SQL to select rows that conform to a number of different criteria. It is a neglected but effective technique for a number of tasks. Although the SQL can appear daunting and complex, it can perform very well if you reduce the rows as much as possible before applying the final logic.
What is division operation?
The division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing. The division is an operation inverse of multiplication.
What is division operation example?

How do I find the remainder of a division 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. All of above platforms support the SQL syntax of MOD().
What is decimal function in SQL?
In Transact-SQL statements, a constant with a decimal point is automatically converted into a numeric data value, using the minimum precision and scale necessary. For example, the constant 12.345 is converted into a numeric value with a precision of 5 and a scale of 3.
How do I select decimal value in SQL?
Use the CAST() function to convert an integer to a DECIMAL data type. This function takes an expression or a column name as the argument, followed by the keyword AS and the new data type. In our example, we converted an integer (12) to a decimal value (12.00).
What are different divisions of SQL and commands give examples of commands in each division?
Types of SQL Commands
- Data Definition Language (DDL) DDL changes the structure of the table like creating a table, deleting a table, altering a table, etc.
- Data Manipulation Language. DML commands are used to modify the database.
- Data Control Language.
- Transaction Control Language.
- Data Query Language.

How do you check division?
You can use multiplication to check your division answer this way.
- Do the division problem.
- Multiply the quotient times the divisor.
- If there is a remainder, add it to the multiplication product.
- Compare this answer to the dividend. They should be the same number (630 = 630).
What is division operator with an example?
If both inputs are integers, the operator performs an integer division, and the output will be an integer. For example, if 3 is divided by 2, the output is 1, or if -3 is divided by 2, the output is -2.
What does the div function do?
The DIV function is used for integer division (x is divided by y). An integer value is returned.
How do you use mod division?
To calculate modulo division: Subtract the divisor from the dividend until the resultant is less than the divisor.
How do you check if a number is divisible by 3 in SQL?
Answer 4f2ff6f542b2e8000101028d For example: 7%3 == 1 because 7 is divisible by 3 two times, with 1 left over. So to check if a number is divisible by 3, you need to determine if dividing the number by three has a remainder of zero. var number = 21; if( number % 3 == 0) { //The number is divisible by three.
