wp db query

对数据库执行 SQL 查询。

此命令在 after_wp_config_load 钩子上运行，在 wp-config.php 加载到作用域之后。

使用 wp-config.php 中指定的 DB_HOST、DB_NAME、DB_USER 和 DB_PASSWORD 数据库凭据执行任意 SQL 查询。

使用 --skip-column-names MySQL 参数从 SELECT 查询中排除表头。通过管道传输输出来完全移除 ASCII 表格。

OPTIONS

请参阅参数语法参考，以详细了解所使用的语法约定。

[<sql>] : 一条 SQL 查询语句。如果未提供，将尝试从 STDIN 读取。

[--dbuser=<value>] : 传递给 mysql 的用户名。默认为 DB_USER。

[--dbpass=<value>] : 传递给 mysql 的密码。默认为 DB_PASSWORD。

[--<field>=<value>] : 传递给 mysql 的额外参数。请参阅 mysql 文档。

[--defaults] : 加载环境的 MySQL 选项文件。默认行为是跳过加载它们，以避免因配置错误而导致失败。

示例

# 执行存储在文件中的查询
$ wp db query < debug.sql

# 查询数据库中的特定值（通过管道移除 ASCII 表格边框）
$ wp db query 'SELECT option_value FROM wp_options WHERE option_name="home"' --skip-column-names
+---------------------+
| https://example.com |
+---------------------+

# 检查数据库中的所有表
$ wp db query "CHECK TABLE $(wp db tables | paste -s -d, -);"
+---------------------------------------+-------+----------+----------+
| Table                                 | Op    | Msg_type | Msg_text |
+---------------------------------------+-------+----------+----------+
| wordpress_dbase.wp_users              | check | status   | OK       |
| wordpress_dbase.wp_usermeta           | check | status   | OK       |
| wordpress_dbase.wp_posts              | check | status   | OK       |
| wordpress_dbase.wp_comments           | check | status   | OK       |
| wordpress_dbase.wp_links              | check | status   | OK       |
| wordpress_dbase.wp_options            | check | status   | OK       |
| wordpress_dbase.wp_postmeta           | check | status   | OK       |
| wordpress_dbase.wp_terms              | check | status   | OK       |
| wordpress_dbase.wp_term_taxonomy      | check | status   | OK       |
| wordpress_dbase.wp_term_relationships | check | status   | OK       |
| wordpress_dbase.wp_termmeta           | check | status   | OK       |
| wordpress_dbase.wp_commentmeta        | check | status   | OK       |
+---------------------------------------+-------+----------+----------+

# 将额外参数传递给 MySQL
$ wp db query 'SELECT * FROM wp_options WHERE option_name="home"' --skip-column-names
+---+------+------------------------------+-----+
| 2 | home | http://wordpress-develop.dev | yes |
+---+------+------------------------------+-----+

多站点使用说明

请注意，全局 --url 参数对此命令无效。如需查询主站点之外其他站点的数据，您需要手动修改表名，使用包含站点 ID 的前缀。

例如，要获取第二个站点的 home 选项值，请按如下方式修改上述示例：

$ wp db query 'SELECT option_value FROM wp_2_options WHERE option_name="home"' --skip-column-names
+----------------------+
| https://example2.com |
+----------------------+

要确认目标站点的 ID，可使用 wp site list 命令：

# wp site list --fields=blog_id,url
+---------+-----------------------+
| blog_id | url                   |
+---------+-----------------------+
| 1       | https://example1.com/ |
| 2       | https://example2.com/ |
+---------+-----------------------+
