MYSQL：使用来自两个子查询的数据创建插入,mysql,sql,Mysql,Sql,我知道在从数据库中选择行之后，可以使用子查询进行插入 INSERT INTO wp_43_term_relationships (object_id, term_taxonomy_id, term_order) SELECT ID, 8363, 0 FROM ( SELECT DISTINCT wp_43_posts.ID FROM wp_43_posts INNER JOIN wp_43_term_relationships ON wp_43_term_relationships.object

我知道在从数据库中选择行之后，可以使用子查询进行插入

INSERT INTO wp_43_term_relationships (object_id, term_taxonomy_id, term_order)
SELECT ID, 8363, 0 FROM
( SELECT DISTINCT
wp_43_posts.ID
FROM
wp_43_posts
INNER JOIN wp_43_term_relationships ON wp_43_term_relationships.object_id = wp_43_posts.ID
INNER JOIN wp_43_term_taxonomy ON wp_43_term_taxonomy.term_taxonomy_id = wp_43_term_relationships.term_taxonomy_id
WHERE  (wp_43_term_taxonomy.term_id = 4613 OR wp_43_term_taxonomy.term_id = 4615) AND wp_43_term_taxonomy.term_id != 8363 ) posts

但是，如果我不需要硬编码8363，而是需要从另一个查询派生它呢？例如，我需要从

SELECT
wp_43_term_taxonomy.term_taxonomy_id
FROM
wp_43_term_taxonomy
WHERE
wp_43_term_taxonomy.term_id = 8363

只需将其放入子查询并使用额外的联接：

INSERT INTO wp_43_term_relationships (object_id, term_taxonomy_id, term_order)
SELECT ID, someval, 0 FROM
( SELECT DISTINCT
wp_43_posts.ID,t.term_taxonomy_id someval
FROM
wp_43_posts
INNER JOIN wp_43_term_relationships ON wp_43_term_relationships.object_id = wp_43_posts.ID
INNER JOIN wp_43_term_taxonomy ON wp_43_term_taxonomy.term_taxonomy_id = wp_43_term_relationships.term_taxonomy_id
WHERE  (wp_43_term_taxonomy.term_id = 4613 OR wp_43_term_taxonomy.term_id = 4615) AND wp_43_term_taxonomy.term_id != 8363

是的，您可以，请参见下面的修改后的查询。基本上，将该列包含到要为

如果用（）中的第二个查询替换常量，它应该可以工作。像这样：

INSERT INTO wp_43_term_relationships (object_id, term_taxonomy_id,term_order)
SELECT ID,
(SELECT wp_43_term_taxonomy.term_taxonomy_id FROM wp_43_term_taxonomy WHERE wp_43_term_taxonomy.term_id = 8363),
0 FROM
... remaining of the original ...

至少如果您只需要1个值，否则最好将这个额外的表连接到其他表。

如果您用（）中的第二个查询替换常量，它应该可以工作。像这样：

INSERT INTO wp_43_term_relationships (object_id, term_taxonomy_id,term_order)
SELECT ID,
(SELECT wp_43_term_taxonomy.term_taxonomy_id FROM wp_43_term_taxonomy WHERE wp_43_term_taxonomy.term_id = 8363),

这里似乎有几个硬编码的值；也许是时候考虑生成一个包含一个简单脚本的插入查询的.sql文件（无论是您首选的语言PHP、Python等），都允许在将值绑定到查询之前将其检索为变量，准备标识符数组以在循环中使用…@FrostyZ创建一个wp-cli命令需要2分钟，你是对的，但是我必须使用mysql，因为有时候它更容易。我很好奇。我可以简单地运行另一个查询并对值进行硬编码，但我想知道如何做到这一点！看起来这里有几个硬编码的值；也许是时候考虑生成一个包含一个简单脚本的插入查询的.sql文件（无论是您首选的语言PHP、Python等），都允许在将值绑定到查询之前将其检索为变量，准备标识符数组以在循环中使用…@FrostyZ创建一个wp-cli命令需要2分钟，你是对的，但是我必须使用mysql，因为有时候它更容易。我很好奇。我可以简单地运行另一个查询并对值进行硬编码，但我想知道如何做到这一点！看起来这里有几个硬编码的值；也许是时候考虑生成一个包含一个简单脚本的插入查询的.sql文件（无论是您首选的语言PHP、Python等），都允许在将值绑定到查询之前将其检索为变量，准备标识符数组以在循环中使用…@FrostyZ创建一个wp-cli命令需要2分钟，你是对的，但是我必须使用mysql，因为有时候它更容易。我很好奇。我可以简单地运行另一个查询并对值进行硬编码，但我想知道如何做到这一点！看起来这里有几个硬编码的值；也许是时候考虑生成一个包含一个简单脚本的插入查询的.sql文件（无论是您首选的语言PHP、Python等），都允许在将值绑定到查询之前将其检索为变量，准备标识符数组以在循环中使用…@FrostyZ创建一个wp-cli命令需要2分钟，你是对的，但是我必须使用mysql，因为有时候它更容易。我很好奇。我可以简单地运行另一个查询并对值进行硬编码，但我想知道如何做到这一点！
