我的查询声明
$sql = "SELECT *
FROM tithings
INNER JOIN marriage ON tithings.Marr_ID = marriage.MarrID
INNER JOIN tithings_payment ON tithings_payment.Tithing_ID = tithings.Tithing_ID WHERE YEAR( STR_TO_DATE( Dateregistered, '%Y' ) ) <= $year LIMIT $start_from, 30";
Paid_Month_Year = Month（Jan-Dec）我使用PHP if else语句
结果就是这样。
Family Name | Jan | Feb | Mar | Apr | May | June | July | Aug | Sep | Oct | Nov | Dec |
Name(5) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 15.00 | 0 | 0 | 0 |
Name(5) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 15.00 | 0 | 0 |
Name(6) | 15.00 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Name(6) | 0 | 15.00 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
注意：我试过Distinct In查询无法正常工作。
我希望我的输出看起来像这样;
Family Name | Jan | Feb | Mar | Apr | May | June | July | Aug | Sep | Oct | Nov | Dec |
Name(5) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 15.00 | 15.00 | 0 | 0 |
Name(6) | 15.00 | 15.00 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
答案 0 :(得分：0)
这样的东西应该有效，你必须对你在group语句中没有使用的列做些什么。在你的情况下，采用SUM是有意义的，因为有人可以在同一个月支付两次，也可以在另一个支付。
SELECT
Family_Name,
SUM(Jan),
SUM(Feb)
....
SUM(Dec)
FROM
tithings
INNER JOIN marriage ON tithings.Marr_ID = marriage.MarrID
INNER JOIN tithings_payment ON tithings_payment.Tithing_ID = tithings.Tithing_ID
WHER
YEAR( STR_TO_DATE( Dateregistered, '%Y' ) ) <= $year
GROUP BY
Family_Name
LIMIT $start_from, 30
