Question

我有一个包含100个INSERT语句的SQL文件（请参见下面的示例），该文件用于创建SQLITE数据库。我现在正在创建一个MySQL数据库，并希望将此代码转换为单个INSERT语句（下面的示例。）

我这样做的主要原因是使它看起来更好一点。我希望会有一个不错的在线转换器，但一直无法在这里找到建议。

当前的SQL文件有数千个：

insert into customer (customer_id, customer_title, customer_forename, customer_surname, customer_address_1, customer_address_2, customer_town_city, customer_county, customer_postcode, customer_telephone_number, customer_email_address, customer_notes) values ('955773', 'Mrs', 'Valle', 'Keave', '95380', 'Gale', 'Helena', 'Montana', '59623', '406-989-2003', 'vkeave0@shareasale.com', 'grow world-class deliverables');
insert into customer (customer_id, customer_title, customer_forename, customer_surname, customer_address_1, customer_address_2, customer_town_city, customer_county, customer_postcode, customer_telephone_number, customer_email_address, customer_notes) values ('818817', 'Mrs', 'Melessa', 'Parmby', '914', 'Fairview', 'Montgomery', 'Alabama', '36114', '334-255-3054', 'mparmby1@addtoany.com', 'iterate seamless schemas');

如果对此有个快速解决方法，请告诉我。现在已被标记为重复项的问题是相同的。该问题与查询速度有关，这与将一种格式转换为另一种格式有关。

Answer 1

您可以通过执行以下操作插入多个记录：

INSERT INTO customer (customer_id, customer_title, customer_forename, customer_surname, customer_address_1, customer_address_2, customer_town_city, customer_county, customer_postcode, customer_telephone_number, customer_email_address, customer_notes)
VALUES ('955773', 'Mrs', 'Valle', 'Keave', '95380', 'Gale', 'Helena', 'Montana', '59623', '406-989-2003', 'vkeave0@shareasale.com', 'grow world-class deliverables'),
('818817', 'Mrs', 'Melessa', 'Parmby', '914', 'Fairview', 'Montgomery', 'Alabama', '36114', '334-255-3054', 'mparmby1@addtoany.com', 'iterate seamless schemas'),
.
.
.
.
.
('801027', 'Mrs', 'Bayard', 'Brindley', '76049', 'Duke', 'El Paso', 'Texas', '79968', '915-207-0519', 'bbrindley9@mysql.com', 'visualize enterprise networks');

您必须用逗号分隔每个新条目：VALUES(.....), (........),，然后最后一个条目将以分号结尾：(......);

Answer 2

insert支持values的多个值。这不适合您吗？

insert into customer (customer_id, customer_title, customer_forename, customer_surname, customer_address_1, customer_address_2, customer_town_city, customer_county, customer_postcode, customer_telephone_number, customer_email_address, customer_notes)
    values ('955773', 'Mrs', 'Valle', 'Keave', '95380', 'Gale', 'Helena', 'Montana', '59623', '406-989-2003', 'vkeave0@shareasale.com', 'grow world-class deliverables'),
           ('818817', 'Mrs', 'Melessa', 'Parmby', '914', 'Fairview', 'Montgomery', 'Alabama', '36114', '334-255-3054', 'mparmby1@addtoany.com', 'iterate seamless schemas')
           . . .

因此，您可以在单个insert中插入多个行。但是，您不能逐列插入数据。

Answer 3

您可以插入，但必须在值的最后部分插入分号，并在每个值的最后一个值部分之前插入逗号EX：

   INSERT INTO [dbo].[tbl_Page]
       ([PageTitle]
       ,[Link]
       ,[Status]
       ,[CreatedDate]
       ,[Description])
 VALUES
       ('demo','demo',1,'12/11/2019','demo'),
       ('demo','demo',1,'12/11/2019','demo'),
       ('demo','demo',1,'12/11/2019','demo'),
       ('demo','demo',1,'12/11/2019','demo'),
       ('demo','demo',1,'12/11/2019','demo');

经过测试

Answer 4

您可以使用phpMyAdmin（https://www.phpmyadmin.net/）来实现，只需选择导出表然后导出即可。

Answer 5

使用PHP查看以下解决方案，您可以使用数组形式的插入列表，然后您可以指定每个插入组的计数我使用了 2 个函数

get_string_between 函数

joinInsertQueriesFromArray 函数

 function get_string_between($string, $start, $end){
         $string = ' ' . $string;
         $ini = strpos($string, $start);
         if ($ini == 0) return '';
         $ini += strlen($start);
         $len = strpos($string, $end, $ini) - $ini;
         return substr($string, $ini, $len);
 }

 /*
     VALUES ( -- cols -- );
     note: mantain space eg <-space-> VALUES <-space->(
 */
 function joinInsertQueriesFromArray($insertArray,$counts_per_group = 200){
     //$insertArray

     if(sizeof($insertArray) == 0) return [];

     //create a header from first query
     $query = $insertArray[0];
     $query = str_replace("values(", "VALUES (", $query);
     $query = str_replace("values (", "VALUES (", $query);
     $separator = strtoupper(" values (");
     $splitedQuery = explode($separator, $query);
     if(sizeof($splitedQuery) == 0) return [];
     $SQL_HEADER = $splitedQuery[0];
     //echo "HEADER - ".$SQL_HEADER."\n\n";

     //
     $insertSQLValuesArray = [];
     $groupSize = $counts_per_group;
     $currentInsertSQLValues = "";
     $createdAwbsListArray = [];

     for($i = 0;$i < sizeof($insertArray);$i++){
         $v = $insertArray[$i];
         $v = str_replace("values(", "VALUES (", $v);
         $v = str_replace("values (", "VALUES (", $v);

         $value = get_string_between($v,"VALUES (",");");

         $currentInsertSQLValues .= "(".$value.")";

         if(($i+1) % $groupSize == 0){
             array_push($insertSQLValuesArray, $currentInsertSQLValues.";");
             $currentInsertSQLValues = "";
         }else{
             $currentInsertSQLValues .= ",";
         }

     }
     if($currentInsertSQLValues != "") array_push($insertSQLValuesArray, rtrim($currentInsertSQLValues,",") .";");//values < group size:last values

     $statements = [];
     //combile INSERT INTO with values header + values
     for($i = 0;$i < sizeof($insertSQLValuesArray);$i++){
         $statement = $SQL_HEADER.' VALUES '.$insertSQLValuesArray[$i];
         array_push($statements, $statement);
     }

     //echo json_encode($statements);
     return $statements;

 }

用法


$list = [
            "INSERT into users(username,id) values ('GRAND',1);",
            "INSERT into users(username,id) values ('MASTER',2);",
            "INSERT into users(username,id) values ('DEOGRATIAS',3);",
            "INSERT into users(username,id) values ('DAMAS',4);",
            "INSERT into users(username,id) values ('NGEREZA',5);"
        ];
            $list = joinInsertQueriesFromArray($list,3);
            //echo json_encode($list);
