Dynamic 通过PHP使用加载数据填充导入大数据

如上所述，经过20个小时的研究，我提出了4个查询来将大数据加载到数据库中，但是，它得到了错误“queryexecutefailed:ERRNO:（）”，并且没有任何数据被插入到所选表中。出了什么问题，我遗漏了什么吗

下面是文件数据 file.txt V0012、aptext1、aptext2、aptext3、aptext6、apDesc2、apDesc3、USER0031

$temp\u table\u query=“创建表

temp\u清单列表

（生成的\u id varchar（60）不为空，” “app_text1 varchar（60）不为空，app_text2 varchar（60）不为空，app_text6 varchar（60）不为空，” “app_desc2 varchar（500）不为空，app_desc3 varchar（500）不为空，由varchar（50）不为空）创建；”

SQL加载数据填充在web共享主机上不起作用，因此我更改了方法

         if (!($temp_table_stmt = $conn->query[$temp_table_query])) {
                echo "\nQuery execute failed: ERRNO: (" . $conn->error . ") " . $conn->error;
        }
        
        $load_data_query = " LOAD DATA INFILE " .'"upload/docs/file.txt"'." INTO TABLE `temp_inventoryList` "
                           ."FIELDS TERMINATED BY ',' "
                           ."LINES TERMINATED BY '\n' "
                           ."(generated_id,app_text1, app_text2, app_text6,app_desc2,app_desc3,created_by)"
                           ."SET created_date=NOW(), app_display='Y'; ";
        
        if (!($load_data_stmt = $conn->query[$load_data_query])) {
                echo "\nQuery execute failed: ERRNO: (" . $conn->error . ") " . $conn->error;
        }
        
        $insert_query = " INSERT INTO `app_product` VALUES(generated_id,app_text1, app_text2, app_text6,app_desc2,app_desc3, created_by, created_date, app_display) "
                        ." SELECT generated_id, app_text1, app_text2, app_text6, app_desc2, app_desc3, created_by, created_date, app_display "
                        ." FROM `temp_inventoryList`; ";
        
        if (!($insert_stmt = $conn->query[$insert_query])) {
                echo "\nQuery execute failed: ERRNO: (" . $conn->error . ") " . $conn->error;
        }

        $drop_temp_query = " TRUNCATE TABLE `temp_inventoryList`;";
        
        if (!($drop_temp_stmt = $conn->query[$drop_temp_query])) {
                echo "\nQuery execute failed: ERRNO: (" . $conn->error . ") " . $conn->error;
        }
