这个MySQL查询有问题吗？

Question

public function create() {


        echo $this->equipment->getCatId() . "<br/>";
        echo $this->equipment->getName() . "<br/>";
        echo $this->equipment->getYear() . "<br/>";
        echo $this->equipment->getManufacturer() . "<br/>";
        echo $this->equipment->getModel() . "<br/>";
        echo $this->equipment->getPrice() . "<br/>";
        echo $this->equipment->getLocation() . "<br/>";
        echo $this->equipment->getCondition() . "<br/>";
        echo $this->equipment->getStockNum() . "<br/>";
        echo $this->equipment->getInformation() . "<br/>";
        echo $this->equipment->getDescription() . "<br/><br/>";


        $db = Connect::connect();
        $current_time = date('y M d');
        $query = "INSERT INTO equipment (cat_id, name, year, manufacturer, model, price, location, condition,
                                         stock_num, information, description, created, modified)

                                         VALUES

                                        ({$this->equipment->getCatId()}, {$this->equipment->getName()}, {$this->equipment->getYear()},
                                         {$this->equipment->getManufacturer()}, {$this->equipment->getModel()}, {$this->equipment->getPrice()},
                                         {$this->equipment->getLocation()}, {$this->equipment->getCondition()}, {$this->equipment->getStockNum()},
                                         {$this->equipment->getInformation()}, {$this->equipment->getDescription()}, '$current_time', '$current_time')";

        $result = $db->query($query);

        return $db->insert_id;

    }

• The echos at the top all display valid data that fit the database schema.
• There are no connection errors

Any ideas?

Thanks in advance!

Here is the echo'ed query

INSERT INTO equipment (cat_id, name, year, manufacturer, model, price, location, condition, stock_num, information, description, created, modified) VALUES (1, 'r', 1, 'sdf', 'sdf', '2', 'd', 'd', '3', 'asdfasdfdf', 'df', '10 May 10', '10 May 10')

MySQL is giving: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'condition, stock_num, information, description, created, modified) VALUES (1, 'r' at line 1

Here is the SQL export from PhpMyAdmin in case someone wants to try duplicating this issue: http://pastie.org/954206

BLEHBLEHSDFOHSE -- So apparently, 'condition' is also a reserved word... threw in some backticks, then it started working.

Answer 1

YEAR is a reserved word in MySQL. If you're going to use it, you're going to need to backtick (ie `year` )

Answer 2

Assuming location, information and description are strings quotes are missing.

INSERT INTO equipment (cat_id, name, year, manufacturer, model, price, location, condition,
                                         stock_num, information, description, created, modified)

                                         VALUES

                                        ({$this->equipment->getCatId()}, {$this->equipment->getName()}, {$this->equipment->getYear()},
                                         '{$this->equipment->getManufacturer()}', {$this->equipment->getModel()}, {$this->equipment->getPrice()},
                                         '{$this->equipment->getLocation()}', {$this->equipment->getCondition()}, {$this->equipment->getStockNum()},
                                         '{$this->equipment->getInformation()}', '{$this->equipment->getDescription()}', '$current_time', '$current_time')";

Answer 3

Varchar, char and text fields need quotes around them to insert. Echo out the SQL query and check this is happening.

Answer 4

as far as i see it at this point, your problem was year field with no quotes...

INSERT INTO equipment (cat_id, name, year, manufacturer, model, price, location, condition, stock_num, information, description, created, modified) VALUES (1, 'r', 1 , 'sdf', 'sdf', '2', 'd', 'd', '3', 'asdfasdfdf', 'df', '10 May 10', '10 May 10')

here, the problem is cat_id WITH quotes

Query: INSERT INTO equipment (cat_id, name, year, manufacturer, model, price, location, condition, stock_num, information, description, created, modified) VALUES ( '1' , 'asdf', '234', 'adf', 'asdf', '34', 'asdf', 'asdf', '234', 'asdf', 'asdf', '10 May 10', '10 May 10')

Answer 5

BLEHBLEHSDFOHSE-显然，“条件”也是一个保留字...加上一些反引号，然后开始起作用。

Answer 6

Stop using mysql_query() and switch to mysqli and prepared statements , then you don't need all that obtuse OOP in your SQL string. It would look cleaner like this:

$query = 'INSERT INTO table (id,name,age) VALUES (?,?,?)';
