Question

我正在尝试将数据列上传到mySQL数据库。以下是遇到问题的代码片段。

cursor = mariadb_connection.cursor()
cursor.execute=("CREATE TABLE IF NOT EXISTS table1 (ts TIMESTAMP, col2 char(10), col3 decimal (7,2), col4 decimal (5,2), col5 decimal (7,2), col6 decimal (5,2))")
sql ="INSERT INTO table1 (ts, col2, col3, col4, col5, col6)" 
sql += "VALUES (NULL, %s, %s, %s, %s, %s)"
cursor.execute(sql,(var2, var3, var4, var5, var6))

运行代码时，出现以下错误： cursor.execute(sql,(var2, var3, var4, var5, var6)) TypeError: 'str' object is not callable

请注意，var2到var6是从decimal个对象转换的str个对象。

更新：从有问题的行中删除=后，我现在似乎又出现了另一个错误：mysql.connector.errors.ProgrammingError: 1054 (42S22): Unknown column 'ts' in 'field list'.

任何想法我做错了什么？

更新：未知列问题的解决方法是删除现有表，然后再次运行脚本

从include(WPtest_PLUGIN_PATH.'/admin/includes/dompdf/lib/html5lib/Parser.php'); include(WPtest_PLUGIN_PATH.'/admin/includes/dompdf/lib/php-font-lib/src/FontLib/Autoloader.php'); include(WPtest_PLUGIN_PATH.'/admin/includes/dompdf/lib/php-svg-lib/src/autoload.php'); include(WPtest_PLUGIN_PATH.'/admin/includes/dompdf/src/Autoloader.php'); Dompdf\Autoloader::register(); use Dompdf\Dompdf; class WPtest_Save_PDF{ //use Dompdf\Dompdf; function __construct(){ add_shortcode( 'save_me',array($this,'print_callback')); } function print_callback(){ if(isset($_GET['print'])) { $dompdf = new Dompdf(); $dompdf->loadHtml("test"); // (Optional) Setup the paper size and orientation $dompdf->setPaper('A4', 'landscape'); // Render the HTML as PDF $dompdf->render(); // Output the generated PDF to Browser $dompdf->stream(); exit(); } } } new WPtest_Save_PDF;删除=符号并使用此

cursor.excecute=(...)
