Expert Solution & Answer
Chapter 8, Problem 2RQ
Explanation of Solution
Round a number to a specific number of decimal places in Oracle, Access and SQL Server:
- In Oracle, Access and SQL server, user can round a number to a specific number of decimal places by using “ROUND” function.
“ROUND” function:
- This function is used to rounds a number to a specified number of decimal places.
- This function contains more than one argument.
- Syntax for “ROUND” function:
ROUND(number, DecimalPlaces)
- From the given syntax, the argument “number” defines the value to be rounded and the argument “DecimalPlaces” represents the number of decimal places to which to round the result.
- Consider an example, “ROUND(46.78, 0)” will give the result as “47”...
Explanation of Solution
Remove each value to the right of the decimal places using Oracle, Access and Server:
For Oracle and SQL Server:
For Oracle and SQL server, user can use the “FLOOR” function to remove each number to the right of decimal point.
“FLOOR” function:
- This function is used to truncate everything to the right of decimal value.
- Syntax for “FLOOR” function:
FLOOR(value)
From the given syntax, the “value” represents numeric value.
Example of “FLOOR” function:
The example for “FLOOR” function in query concept is given below:
SELECT FLOOR(86.32) AS COMPUTED_VALUE;
- The above query is used to eliminate everything to the right of decimal value using “FLOOR” function.
- The computed value is represented by “COMPUTED_VALUE” using “AS” operator.
When the query is executed, the following output will be displayed...
