如何在CSCART中创建和执行SQL查询？

Question

只想问我如何使用CSCART创建一个简单的查询？

我的代码中包含此查询，但不显示查询结果。这是我的代码：

$company_list = db_query('SELECT company FROM cscart_companies ORDER BY company LIMIT 100');

fn_print_r($company_list);

foreach($company_list as $t){
    echo $t['company'];
}

但是它仅显示来自我的print_r（）的值：

mysqli_result Object
(
    [current_field] => 0
    [field_count] => 1
    [lengths] => 
    [num_rows] => 100
    [type] => 0
)

Answer 1

您需要使用

$company_list = db_get_array('SELECT company FROM ?:companies ORDER BY company LIMIT 100');
foreach($company_list as $t){
    echo $t['company'];
}

Answer 2

对我来说这有效：

$company_list = db_get_array('SELECT company FROM ?:companies ORDER BY company LIMIT 100');
foreach ($company_list as $t){
   foreach ($t as $r) {
     echo $r['company'];
   }
}
