Question

我想从一个表中读取所有数据并将一些数据插入到另一个表中。我的查询是

  INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
  VALUES ( 
      (SELECT magazine_subscription_id, 
              subscription_name, 
              magazine_id 
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC), '1')

但我收到了错误

  #1136 - Column count doesn't match value count at row 1

请帮帮我。

Answer 1

您可以使用INSERT...SELECT语法。请注意，您可以引用＆＃39; 1＆＃39;直接在SELECT部分。

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
SELECT magazine_subscription_id, 
       subscription_name, 
       magazine_id, 
       '1'
FROM tbl_magazine_subscription
ORDER BY magazine_subscription_id ASC

Answer 2

如果要将一个表中的所有数据插入到另一个表中，则只需要一个非常简单的sql

INSERT INTO destinationTable  (SELECT * FROM sourceDbName.SourceTableName);

Answer 3

它不会像这样工作。

当您尝试使用查询插入行时，查询中应该包含所有值。

要插入上述问题 magazine_subscription_id, subscription_name, magazine_id, status 在您选择的查询中 magazine_subscription_id, subscription_name, magazine_id, status 1这是不可能的。

如果要插入，则需要使用直接值查询

进行插入

Answer 4

实际上，从一个表到另一个表的复制数据的mysql查询是
Insert into table2_name (column_names) select column_name from table1
其中，值从table1复制到table2

Answer 5

如果有像“id”这样的主键你必须排除它，例如我的php表有：id，col2，col3，col4列。 id是主键，所以如果我运行此代码：

INSERT INTO php  (SELECT * FROM php);

我可能会收到此错误：

#1062 - Duplicate entry '1' for key 'PRIMARY'

所以这是解决方案，我排除了“id”键：

INSERT INTO php ( col2,col3,col4)  (SELECT col2,col3,col4 FROM php2);

所以我的新php表已经有了所有php2表行。

试试这个。你做错了。

    INSERT INTO mt_magazine_subscription( 
    magazine_subscription_id, 
    subscription_name, 
    magazine_id, status) VALUES ( 
         (SELECT magazine_subscription_id, subscription_name, 
                 magazine_id,1 as status FROM tbl_magazine_subscription 
                 ORDER BY magazine_subscription_id ASC)
    )

Answer 8

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
VALUES ( 
      (SELECT magazine_subscription_id, 
              subscription_name, 
              magazine_id,'1' as status
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC));

Answer 9

INSERT INTO destination_table ( 
      Field_1, 
      Field_2, 
      Field_3) 
SELECT Field_1, 
      Field_2, 
      Field_3 
      FROM source_table;

但这是一个不好的MYSQL

请改为：

drop the destination table: DROP DESTINATION_TABLE;
CREATE TABLE DESTINATION_TABLE AS (SELECT * FROM SOURCE_TABLE);
