TP number of bound variables does not match number of tokens

• PHP Version: PHP 5.4.16

• thinkphp version: 3.2.3

Directly on the 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)

$sql = $ReportLost->fetchsql (True)->add ($data);

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)

Next execution $result = $ReportLost->add($data); will cause an error:

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

In MySQL, however, the direct execution $sql of the

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)

is available for insertion.

Data table structure

--Table structure ' report_lost '--create table IF not EXISTS ' report_lost ' (' id ' int (one) not NULL, ' title ' varchar) CHARACTER S ET utf8mb4 default null, ' keyword ' varchar (+) CHARACTER set utf8mb4 DEFAULT null, ' area ' varchar (CHARACTER set UTF)  8MB4 default NULL, ' brand ' varchar (CHARACTER) set utf8mb4 DEFAULT null, ' sub_brand ' varchar CHARACTER set UTF8MB4 DEFAULT null, ' color ' varchar (CHARACTER set UTF8MB4 not NULL, ' type ' varchar () CHARACTER SET utf8mb4 not NULL, ' Alerted_police ' int (4) NOT null default ' 0 ', ' status ' int (4) is not null default ' 0 ', ' info ' text CHARACTER SET utf8mb4, ' Image ' text CHARACTER set UTF8MB4, ' user ' varchar (CHARACTER set UTF8MB4 DEFAULT NULL, ' email ' varchar () CHARACTER Set UTF8MB4 NOT NULL, ' contact ' varchar (CHARACTER set UTF8MB4 DEFAULT NULL, ' descrpition ' text CHARACTER set UTF8MB4 , ' uuid ' varchar (CHARACTER) SET utf8mb4 DEFAULT ' 00000000-0000-0000-0000-000000000000 ', ' lost_time ' timestamp NULL DE FAULT NULL, ' Create_timE ' timestamp not null default Current_timestamp, ' update_time ' timestamp null default NULL) ENGINE=INNODB default CHARSET =UTF8MB4 Collate=utf8mb4_unicode_ci;

The fields in the table are indeed more than those in $data, but the undefined in $data can be null.

Is this the thinkphp limit? Or a PHP limit? What's the solution, do I need to define all the fields required by MySQL in $data?
