我已经编写了这段代码，用于CodeIgniter中的Dbforge。
$fields = array(
'time_stamp' => array(
'type' => 'STRING',
'constraint' => 9,
'null' => TRUE
),
'curr_property' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_property_cost' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_property' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_property_cost' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_solar_generating' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_solar_export' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_solar_generated' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_solar_export' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_chan1' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_chan2' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'curr_chan3' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_chan1' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_chan2' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'day_chan3' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
)
);
$this->dbforge->add_field($fields);
$this->dbforge->create_table($this->table_name);
我继续收到以下错误
Error Number: 1064

我查找了与错误相关的原因否，但除了this link之外，我无法找到与我的问题相关的任何内容。如果有人能告诉我什么是错的，将不胜感激。

STRING在MySQL中不是有效的数据类型。我认为您正在寻找CHAR或VARCHAR。
