## Removed in SQL SUM decimal point

In SQL, you can remove the decimal point from the SUM calculation result by using the ROUND() function.

Syntax:

<code>ROUND(SUM(expression), decimal_places)</code>

Among them:

expression: the expression that requires the sum.
• decimal_places: The number of decimal places to retain. If 0, the result will be rounded to the nearest integer.

Usage example:

SELECT ROUND(SUM(salary), 0) AS total_salary
FROM employee;

This query will calculate the sum of the salary column in table employee and round the result to the nearest integer.

Note:

ROUND() function only affects the display of query results, not the data in the underlying table.
If you want to permanently remove the decimal point, you can use the ALTER TABLE statement to change the data type of the column. For example:

ALTER TABLE employee ALTER COLUMN salary TYPE INT;

This will change the data type of the salary column to integer, thereby permanently removing the decimal point.
