TP报number of bound variables does not match number of tokens

• PHP version: PHP 5.4.16

• ThinkPHP version: 3.2.3

Go directly to the code:

<code>$data:

Array
(
    [area] => aa
    [brand] => bb
    [color] => cc
    [type] => 通勤车
    [alerted_police] => 0
    [status] => 0
    [lost_time] => 
    [info] => dd
    [email] => email@email.com
    [update_time] => 
    [timestamp] => 1
    [img_info_id] => 201610081621501801716297
)</code>

$sql = $ReportLost->fetchSql(true)->add($data);

<code>INSERT INTO `report_lost` (`area`,`brand`,`color`,`type`,`alerted_police`,`status`,`lost_time`,`info`,`email`,`update_time`) VALUES ('aa','bb','cc','通勤车','0','0',NULL,'dd','email@email.com',NULL)</code>

Next execute $result = $ReportLost->add($data); and an error will be reported:

<code>ERR: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens</code>

However, the in $sql

is executed directly in mysql

<code>mysql> INSERT INTO `report_lost` (`area`,`brand`,`color`,`type`,`alerted_police`,`status`,`lost_time`,`info`,`email`,`update_time`) VALUES ('aa','bb','cc','通勤车','0','0',NULL,'dd','email@email.com',NULL);
Query OK, 1 row affected (0.02 sec)</code>

can be inserted.

Data table structure

<code>-- 表的结构 `report_lost`

CREATE TABLE IF NOT EXISTS `report_lost` (
  `id` int(11) NOT NULL,
  `title` varchar(80) CHARACTER SET utf8mb4 DEFAULT NULL,
  `keyword` varchar(100) CHARACTER SET utf8mb4 DEFAULT NULL,
  `area` varchar(50) CHARACTER SET utf8mb4 DEFAULT NULL,
  `brand` varchar(20) CHARACTER SET utf8mb4 DEFAULT NULL,

  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `update_time` timestamp NULL DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;</code>

There are indeed more fields in the table than in $data, but any undefined fields in $data can be NULL.

Is this a limitation of thinkphp? Or is it a limitation of php? Is there any solution? Do I need to define all the fields required by mysql in $data first?
