Selecting/casting output as integer in SQL

Question

I\'m working on a site that requires me to display a graph of the average number per day of a user input. I have a SQL query already that returns this info to me:

Answer 1

The valid types for a CAST in MySQL are as follows

• BINARY[(N)]
• CHAR[(N)]
• DATE
• DATETIME
• DECIMAL[(M[,D])]
• SIGNED [INTEGER]
• TIME
• UNSIGNED [INTEGER]

So you could use

SELECT CAST(sum(number)/count(number) AS UNSIGNED) as average...

Or SIGNED if the SUM part can ever add up to a negative number.

Answer 2

SELECT 
  CAST(sum(number)/count(number) as UNSIGNED) as average, 
  date 
FROM stats 
WHERE * 
GROUP BY date

Answer 3

Use the DIV operator.

mysql> SELECT 5 DIV 2;
    -> 2

Integer division. Similar to FLOOR(), but is safe with BIGINT values. Incorrect results may occur for noninteger operands that exceed BIGINT range.

Answer 4

how about using MySQL FORMAT Function?

mysql> SELECT FORMAT(12345.123456, 4);
+-------------------------+
| FORMAT(12345.123456, 4) |
+-------------------------+
| 12,345.1235             |
+-------------------------+
1 row in set (0.00 sec)

mysql> SELECT FORMAT(12345.123456, 0);
+-------------------------+
| FORMAT(12345.123456, 0) |
+-------------------------+
| 12,345                  |
+-------------------------+
1 row in set (0.00 sec)

Answer 5

SELECT convert(int, sum(number)/count(number)) as average,
  date
FROM stats
WHERE * GROUP BY date

or

SELECT 
  CAST(sum(number)/count(number) as INT) as average, 
  date 
FROM stats 
WHERE * 
GROUP BY date
