我试图在 Codeigniter 中将当前日期时间插入到 Oracle 数据库中,但出现如下错误:
ORA-01858: a non-numeric character was found where a numeric was expected
INSERT INTO "USER_LOGS" ("USER_ID", "IP_ADDRESS", "LOGIN_DATE", "LOG_TYPE", "USERNAME") VALUES ('1', '::1', 'TO_DATE(''2018-07-17 03:33:03'',''yyyy/mm/dd hh24:mi:ss'')', 'LOG OUT', 'admin')
我的代码:
date_default_timezone_set("Asia/Dhaka");
$timestamp = date('Y-m-d h:i:s');
$timestamp = "TO_DATE('$timestamp','yyyy/mm/dd hh24:mi:ss')";
$user_log_data = array(
'USER_ID' => $ses_data['USER_ID'],
'IP_ADDRESS' => $this->input->ip_address(),
'LOGIN_DATE' => $timestamp,
'LOG_TYPE' => 'LOG OUT',
'USERNAME' => $ses_data['USERNAME']
);
$this->utilities->insertData($user_log_data, 'USER_LOGS');
我的插入语句:
function insertData($post, $tableName)
{
$this->db->trans_start();
$this->db->insert($tableName, $post);
$this->db->trans_complete();
if ($this->db->trans_status() == TRUE) {
return TRUE;
} else {
return FALSE;
}
}
为了您的信息,字段(LOGIN_DATE)的数据类型是TIMESTAMP
谢谢
您可以像这样以不同的方式构建 INSERT 语句:
$sql =
"INSERT INTO USER_LOGS (USER_ID, IP_ADDRESS, LOGIN_DATE, LOG_TYPE, USERNAME)
VALUES (?, ?, TO_DATE(?,'yyyy-mm-dd hh24:mi:ss'), ?, ?)";
$timestamp = date('Y-m-d h:i:s');
$user_log_data = array(
$ses_data['USER_ID'],
$this->input->ip_address(),
$timestamp,
'LOG OUT',
$ses_data['USERNAME']
);
$this->db->query($sql, user_log_data);
或者如果您询问“当前日期时间”,则只需:
$sql =
"INSERT INTO USER_LOGS (USER_ID, IP_ADDRESS, LOGIN_DATE, LOG_TYPE, USERNAME)
VALUES (?, ?, SYSDATE, ?, ?)";
$user_log_data = array(
$ses_data['USER_ID'],
$this->input->ip_address(),
'LOG OUT',
$ses_data['USERNAME']
);
$this->db->query($sql, user_log_data);
但是,我不知道
db->query()
是否也适用于DML语句。
我的数据类型列表是 TIMESTAMP 然后我在我的控制器中使用这样的,它的工作原理:
public function __construct() {
parent::__construct();
public function update() {
$date = new DateTime();
$date->setTimezone(new DateTimeZone('Asia/Jakarta'));
$data = array(
'UPDATED_AT' => $date->format('d-M-y h:i:s A'),
);
$this->kelola->update_piping(array('JOINT_NO' => $joint , 'DWG_PIPE_ID'
=> $dwgPipeId), $data, $data1);
echo json_encode(array("status" => TRUE));
}
请从 $timestamp 变量中删除单引号后尝试。
date_default_timezone_set("Asia/Dhaka");
$timestamp = date('Y-m-d h:i:s');
$timestamp = "TO_DATE($timestamp,'yyyy/mm/dd hh24:mi:ss')";
$user_log_data = array(
'USER_ID' => $ses_data['USER_ID'],
'IP_ADDRESS' => $this->input->ip_address(),
'LOGIN_DATE' => $timestamp,
'LOG_TYPE' => 'LOG OUT',
'USERNAME' => $ses_data['USERNAME']
);
$this->utilities->insertData($user_log_data, 'USER_LOGS');
最后,我通过使用 CI 日期助手并在 system/core/Controller.php 中创建自定义 Oracle 日期格式方法来完成此操作,或者您可以创建自己的继承 CI_Controller 的控制器
//system/core/Controller.php
class CI_Controller {
function __construct() {
parent::__construct();
}
public function oracle_date($timestamp='')
{
$this->load->helper('date');
if($timestamp=='date'){
$datestring = '%d-%M-%Y';
}
else
{
$datestring = '%d-%M-%Y %h.%i.%s %a';
}
$time = time();
$timestamp = strtoupper(mdate($datestring, $time));
return $timestamp;
}
}
//OR
//application/core
class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
public function oracle_date($timestamp='')
{
$this->load->helper('date');
if($timestamp=='date'){
$datestring = '%d-%M-%Y';
}
else
{
$datestring = '%d-%M-%Y %h.%i.%s %a';
}
$time = time();
$timestamp = strtoupper(mdate($datestring, $time));
return $timestamp;
}
}
//Then use as follows:
//application/controllers
class User extends MY_Controller {
public function __construct(){
parent::__construct();
}
$timestamp = $this->oracle_date('timestamp'); //if parameter is 'date' it will return only date like DD-MM-YY and 'timestamp' it will return full timestamp
}
//OR
//application/controllers
class User extends CI_Controller {
public function __construct(){
parent::__construct();
}
$timestamp = $this->oracle_date('timestamp'); //if parameter is 'date' it will return only date like DD-MM-YY and 'timestamp' it will return full timestamp
}
如果您创建自定义控制器,您还可以在 config.php 文件中更改前缀 MY_,例如 $config['subclass_prefix'] = 'MY_';到 $config['subclass_prefix'] = 'Your_';
