大家好，所以我有3张桌子：发票，客户和发票项目，但它似乎没有抓住我的数据，任何人都有任何想法吗？
字符串（216）＆＃34; SELECT * FROM发票，因为我将客户作为c ON c.invoice = i.invoice加入invoice_items作为p ON p.invoice = i.invoice WHERE i.invoice = 1000 ORDER BY i .invoice＆＃34; NULL Errormessage：
自：
var_dump($query);
var_dump($resutls);
printf("Errormessage: %s\n", $mysqli->error);
QUERY：
SELECT *
FROM invoices as i
JOIN customers as c ON c.invoice = i.invoice
JOIN invoice_items as p ON p.invoice = i.invoice
WHERE i.invoice = ".$getID."
ORDER BY i.invoice

答案 0 :(得分：0)
尝试使用此查询
SELECT *
FROM invoices i,customers c,invoice_items p where
c.invoice = i.invoice and p.invoice = i.invoice and
i.invoice = '".$getID."' ORDER BY i.invoice
if ($mysqli->query("SELECT *
FROM invoices i,customers c,invoice_items p where
c.invoice = i.invoice and p.invoice = i.invoice and
i.invoice = '".$getID."' ORDER BY i.invoice") === TRUE) {
printf("No Error Message.\n");
}
答案 1 :(得分：0)
尝试直接在数据库控制台中运行查询，看看是否可以获得结果。如果没有，您需要检查您的数据。
此外，您使用直接输入来构建查询，这很危险。你需要以某种方式转换getid以确保它是一个数字而且只是一个数字。
答案 2 :(得分：0)
试试这个：
SELECT p.*, i.*, c.*
FROM invoice_items p
JOIN invoices i ON i.invoice = p.invoice
JOIN customers c ON c.invoice = i.invoice
WHERE p.invoice = '" . $mysqli->real_escape_string($getID) . "'
请确保：
i.invoice，c.invoice和p.invoice存在且每个表都有索引
PS：此查询将返回多个条目，具体取决于为所选发票存储的invoice_items的数量
