这是一个简单且有效的UPDATE
查询(好吧,INNER JOIN
),并且php代码中没有错误。如果我在php外执行它,查询就会起作用:
UPDATE address_book ab
INNER JOIN address_book_client abc ON abc.contact_id = ab.id
SET ab.name = 'name1', ab.surname = 'surname', ab.cc = '34', ab.phone = '123456789', ab.email = 'a@a.aa', ab.nif = '12345678A', ab.note = 'Blah blah blah...'
WHERE abc.contact_id = 1 AND abc.company_id = 1
执行UPDATE
的代码:
private $name;
// Populate AddressBook Object From User Input
public function PopulateFromUserInput($address_book) {
$this->name = $address_book['name'];
}
// New / Modify / Delete Contact
public function contact($option = '') {
$mysqli = $this->aet->getAetSql();
$exit = FALSE;
} else if ($option == 'modify') {
if ($stmt = $mysqli->prepare('UPDATE address_book ab
INNER JOIN address_book_client abc ON abc.contact_id = ab.id
SET ab.name = ?, ab.surname = ?, ab.cc = ?, ab.phone = ?, ab.email = ?, ab.nif = ?, ab.note = ?
WHERE abc.contact_id = ? AND abc.company_id = ?')) {
$stmt->bind_param('ssiisssii', $this->name, $this->surname, $this->cc, $this->phone, $this->email, $this->nif, $this->note,
$this->id, $this->uploader);
$exit = 'User modified an existing contact.';
} else return array(FALSE, $mysqli->error . '. ID: ' . $this->id);
}
if (!$stmt->execute()) {
$exit = [FALSE, $stmt->error . '. ID: ' . $this->id];
}
return $exit;
}
我确保通过在var_dump($this->name);
之前执行prepare()
来确保新数据存在,并且没有任何问题。此外,$mysqli->error;
和$stmt->error;
都没有错误。我在日志中收到$exit
字符串,表示$stmt->execute()
返回TRUE
。
现在,我启用了mysql日志并查看了一下:
1353 Connect user@localhost as anonymous on table
1353 Query SET NAMES utf8mb4
1353 Prepare UPDATE address_book ab
INNER JOIN address_book_client abc ON abc.contact_id = ab.id
SET ab.name = ?, ab.surname = ?, ab.cc = ?, ab.phone = ?, ab.email = ?, ab.nif = ?, ab.note = ?
WHERE abc.contact_id = ? AND abc.company_id = ?
1353 Execute UPDATE address_book ab
INNER JOIN address_book_client abc ON abc.contact_id = ab.id
SET ab.name = 'name1', ab.surname = 'surname', ab.cc = 34, ab.phone = 123456789, ab.email = 'a@a.aa', ab.nif = '12345678A', ab.not$
WHERE abc.contact_id = NULL AND abc.company_id = 1
1353 Quit
由于某种原因,生成的查询确实存在最后一个字段的问题。
这与UPDATE
查询一起发生,而不是INSERT
:
1433 Connect user@localhost as anonymous on table
1433 Query SET NAMES utf8mb4
1433 Prepare INSERT INTO address_book (name, surname, cc, phone, email, nif, note)
VALUES (?, ?, ?, ?, ?, ?, ?)
1433 Execute INSERT INTO address_book (name, surname, cc, phone, email, nif, note)
VALUES ('name', 'surname', 34, 123456789, 'a@a.aa', '12345678A', 'Blah blah blah...')
1433 Close stmt
1433 Prepare INSERT INTO address_book_client (contact_id, company_id)
VALUES (?, ?)
1433 Execute INSERT INTO address_book_client (contact_id, company_id)
VALUES (3, 1)
1433 Quit
由于某些未知原因,execute()
在$
之后以ab.not
结束该行。
要确保我所做的变量没有问题:
// inside the contact() function
var_dump($this->note);
我得到的是:
string(17) "Blah blah blah..."
知道问题出在哪里?
