WordPress批量替换数据库中内容SQL语句

09/07/2018 建站攻略 0条评论阅读次数 613

需要替换wordpress所有内容中的部分内容，最快方法当然是在phpmyadmin使用sql语句来完成,替换前务必备份数据库,以免出现失误

替换语句

UPDATE wp_posts SET post_content = REPLACE( post_content, 'old content A', 'new content B' )

1	UPDATE wp_posts SET post_content = REPLACE( post_content, 'old content A', 'new content B' )

解释:更新数据库中wp_posts表post_content字段的内容”old content A”为”new content B”(不包含双引号””)

快捷方法:安装WordPress插件Find and Replacer 然后使用插件来,这个方便,但是我更喜欢直接搞SQL
插件使用方法截图如下:

WordPress常用SQL语句

筛选自定义meta的YouRUrl_value包含.pdf的内容，替换为.rar

UPDATE `wp_postmeta` SET `meta_value` = REPLACE( meta_value, '.pdf', '.rar' ) WHERE `meta_key` = 'YouRUrl_value' AND `meta_value` LIKE '%.pdf%'

1	UPDATE `wp_postmeta` SET `meta_value` = REPLACE( meta_value, '.pdf', '.rar' ) WHERE `meta_key` = 'YouRUrl_value' AND `meta_value` LIKE '%.pdf%'

查找wordpress自定义字段yourmeta中包含aaa.com的记录

select * from wp_postmeta WHERE `meta_key` = 'yourmeta_value' AND `meta_value` LIKE '%aaa.com%'

1	select * from wp_postmeta WHERE `meta_key` = 'yourmeta_value' AND `meta_value` LIKE '%aaa.com%'

建立一张表来存储查找的记录

create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yourmeta_value' AND `meta_value` LIKE '%aaa.com%'

1	create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yourmeta_value' AND `meta_value` LIKE '%aaa.com%'

在刚才新建的表中插入包含bbb.com的记录

insert into a_temp(meta_id,post_id,meta_key,meta_value) select * from wp_postmeta WHERE `meta_key` = 'xzy1url_value' AND `meta_value` LIKE '%bbb.com%'

1	insert into a_temp(meta_id,post_id,meta_key,meta_value) select * from wp_postmeta WHERE `meta_key` = 'xzy1url_value' AND `meta_value` LIKE '%bbb.com%'

mysql删除斜杠/之前的内容.如果有多个斜杠/,就多执行几次

update a_temp SET meta_value = SUBSTRING(meta_value, INSTR(meta_value, '/') + 1)

1	update a_temp SET meta_value = SUBSTRING(meta_value, INSTR(meta_value, '/') + 1)

mysql在meta_value字段原有的字符串前插入字符串aaa

update a_temp SET meta_value= CONCAT('aaa',meta_value)

1	update a_temp SET meta_value= CONCAT('aaa',meta_value)

mysql在meta_value字段原有的字符串后插入字符串aaa

update a_temp SET meta_value= CONCAT(meta_value,'aaa')

1	update a_temp SET meta_value= CONCAT(meta_value,'aaa')

mysql字段的字符串中格式化

UPDATE a_temp SET meta_value = REPLACE( meta_value, ' ', '' )
UPDATE a_temp SET meta_value = REPLACE( meta_value, '.', '_' )
UPDATE a_temp SET meta_value = REPLACE( meta_value, '_rar', '.rar' )
UPDATE a_temp SET meta_value = REPLACE( meta_value, ',', '' )
UPDATE `wp_postmeta` SET `meta_value` = REPLACE( meta_value, '.pdf', '.rar' ) WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

UPDATE a_temp SET meta_value = REPLACE( meta_value, ' ', '' )

UPDATE a_temp SET meta_value = REPLACE( meta_value, '.', '_' )

UPDATE a_temp SET meta_value = REPLACE( meta_value, '_rar', '.rar' )

UPDATE a_temp SET meta_value = REPLACE( meta_value, ',', '' )

UPDATE `wp_postmeta` SET `meta_value` = REPLACE( meta_value, '.pdf', '.rar' ) WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

筛选yoururl_value字段里包含bbbb.com内容的数据

select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

1	select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

建立a_temp存放筛选出来的数据

create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

1	create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

将包含cccc.com内容的数据追加插入a_temp

insert into a_temp(meta_id,post_id,meta_key,meta_value) select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%cccc.com%'
create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%';

1 2	insert into a_temp(meta_id,post_id,meta_key,meta_value) select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%cccc.com%' create table a_temp as select * from wp_postmeta WHERE `meta_key` = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%';

以下是删除/左边字符

update a_temp SET meta_value = SUBSTRING(meta_value, INSTR(meta_value, '/') + 1);

1	update a_temp SET meta_value = SUBSTRING(meta_value, INSTR(meta_value, '/') + 1);

替换内容中的部分字符,对内容进行格式化

UPDATE a_temp SET meta_value = REPLACE( meta_value, ' ', '' );
UPDATE a_temp SET meta_value = REPLACE( meta_value, '.', '_' );
UPDATE a_temp SET meta_value = REPLACE( meta_value, '_rar', '.rar' );
UPDATE a_temp SET meta_value = REPLACE( meta_value, ',', '' );
update a_temp SET meta_value= CONCAT('http://xxxx.com/',meta_value);

UPDATE a_temp SET meta_value = REPLACE( meta_value, ' ', '' );

UPDATE a_temp SET meta_value = REPLACE( meta_value, '.', '_' );

UPDATE a_temp SET meta_value = REPLACE( meta_value, '_rar', '.rar' );

UPDATE a_temp SET meta_value = REPLACE( meta_value, ',', '' );

update a_temp SET meta_value= CONCAT('http://xxxx.com/',meta_value);

用临时表的内容替换原字段内容

DELETE FROM wp_postmeta WHERE meta_key = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

1	DELETE FROM wp_postmeta WHERE meta_key = 'yoururl_value' AND `meta_value` LIKE '%bbbb.com%'

将a_temp表处理好后的下载地址,更新到wp_postmeta的yoururl_value

UPDATE wp_postmeta,a_temp  SET wp_postmeta.meta_value=a_temp.meta_value  WHERE wp_postmeta.meta_id=a_temp.meta_id

1	UPDATE wp_postmeta,a_temp SET wp_postmeta.meta_value=a_temp.meta_value WHERE wp_postmeta.meta_id=a_temp.meta_id

删除所有未使用的标签

FROM wp_terms AS a
