打开debug模式后的网页报错：

看了下插件代码，bug是由传入PDO的SHOW TABLE导致的，因为这个语法是Mysql的不兼容Sqlite，修复方法也很简单，把Plugin.php里的Mysql语句改成Sqlite就行了，具体如下：

<?php
/*
private static function hasColumn($table, $field) {
    $db = Typecho_Db::get();
    $sql = "SHOW COLUMNS FROM `".$table."` LIKE '%".$field."%'";
    return count($db->fetchAll($sql)) != 0;
}

private static function hasTable($table) {
    $db = Typecho_Db::get();
    $sql = "SHOW TABLES LIKE '%".$table."%'";
    return count($db->fetchAll($sql)) != 0;
}
*/

private static function hasColumn($table, $field) {
    $db = Typecho_Db::get();
    $sql = "SELECT ".$field." FROM ".$table;
    try {
        $db->fetchAll($sql);
    } catch(\Typecho_Db_Query_Exception $e) {
        return false;
    }
    return true;
}

private static function hasTable($table) {
    $db = Typecho_Db::get();
    $sql = "SELECT * FROM sqlite_master WHERE type='table' AND name='".$table."'";
    return count($db->fetchAll($sql)) != 0;
}

ExSearch

值得一提的是VOID作者的另一个插件Exsearch在Sqlite3下同样也会报错，解决方法大同小异，打开debug模式看哪儿语法不匹配改就完事，如果懒得改可以直接用我改好的
