我的系统似乎无法将更新写入表格行而没有任何错误 查询详细信息是一个简单的UPDATE，报告为成功，但数据未写入数据库表行。
我有一个用于处理所有sql读/写的对象。包含成功事务后的Object转储。

[pdo:protected] => PDO Object

如果我在执行后立即停止执行脚本（die（）;），那么数据就会被正确存储，所以我相信这是从内存到磁盘的某种数据刷新失败。 我对服务器的设置是：
character-set-server = utf8
collation-server = utf8_unicode_ci
default-storage-engine = InnoDB
innodb_change_buffering = all
innodb_buffer_pool_size = 800M
innodb_log_file_size = 256M
innodb_log_buffer_size = 4M
innodb_flush_log_at_trx_commit = 2
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_file_per_table = ON
max_heap_table_size = 64M
query_cache_size = 32M
table_cache = 256
read_buffer_size = 8M
read_rnd_buffer_size = 8M
sort_buffer_size = 8M
tmp_table_size = 64M
我的连接设置为：
private function setSQLMode()
{
$config = new config();
$setting = $config->get('setting');
if (isset($setting['System']['installtype']) && $setting['System']['installtype'] == 'Production')
$this->getConnection()->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_SILENT); // Production
else
$this->getConnection()->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); //Testing and Development
$this->getConnection()->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
$this->getConnection()->setAttribute(PDO::ATTR_AUTOCOMMIT, true);
$this->version = $this->getVersion();
if ($this->version > '5.7') //Default for 5.7.x is STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER
$result = $this->getConnection()->prepare("SET SESSION `sql_mode` = ''");
elseif ($this->version > '5.6') // Default for 5.6.x is NO_ENGINE_SUBSTITUTION
$result = $this->getConnection()->prepare("SET SESSION `sql_mode` = ''");
else // Default for < 5.6 is ''
$result = $this->getConnection()->prepare("SET SESSION `sql_mode` = ''");
$result->execute(array());
}
有没有人知道这里可能会发生什么？在更改设置和阅读其他帖子后，我无法在静默无法写入数据时感到茫然。任何帮助，将不胜感激！ 克雷格
虚拟机上的RAM是1G，所以很小......

对于一台小型的1GB＆＃34;机器＆＃34;，你可能会因为这些＆＃34;高＆＃34;而疯狂交换。设置：
innodb_buffer_pool_size = 800M --> 60M
max_heap_table_size = 64M --> 5M
query_cache_size = 32M --> 5M
table_cache = 256 --> 100
read_buffer_size = 8M --> 4M
read_rnd_buffer_size = 8M --> 4M
sort_buffer_size = 8M --> 4M
tmp_table_size = 64M --> 5M
不要跨列显示数组;为公民身份，地址，电话等制作额外的表格。
