SQL选择包含字符串的所有表的所有列的所有行

Question

I dont really know SQL but have been tasked with importing content to a new WordPress site from an old one. All went well bar the internal links have kept the old site url. eg post image url is:

www.oldsite.com/content/uploads/01/foo.jpg

instead of

www.newsiteurl.com/content/uploads/01/foo.jpg

I took a look through the DB via phpMyAdmin but could find no direct reference to the old site url - not even in the post's content. New links in work fine but Im not about to trudge through 3 years worth of posts replacing urls.

Anyone know where this url is set? If not how can I search the WP SQL DB for all items of all tables for any cell that contains "oldurl.com"?

I already tried

SELECT * FROM * WHERE * LIKE '%oldurl%'

But phpMyAdmin told me SQL thought I was having it on; it said #1064 you have an error in your syntax

Answer 1

You're trying to use WHERE * LIKE something in a SQL statement. You Can't Do That??. You have to mention the specific column name.

The fields you're looking for are in the wp_options table. They have the option_name s of siteurl and home .

You really should use the built-in import and export features; this business of cloning a site by copying the data tables is somewhat tricky.

If you're spelunking and trying to figure out what's where, dump the database to an SQL file, then open that file up in a text editor, then search for things.

I used the tool at https://interconnectit.com/products/search-and-replace-for-wordpress-databases/ As suggested by @NathanDawson. It's a really neat little plugin that found some entries I'd missed in the post_content table.
