mysql - Remove string value after HTML delimiter from database? -


i'm migrating website different platform. inside database, have column named excerpt supposed contain intro text blog posts. after migrating database, i've come find excerpt column , content column duplicates of each other identical values. basic schema looks follows:

-------------------------------------------------------------------------- id | title       | excerpt                                     | content | -------------------------------------------------------------------------- 1  | post.  |<p>text want.</p><p>text don't want.</p> |<p>text..| 2  | post.  |<p>text want.</p><p>text don't want.</p> |<p>text..| 3  | next post.  |<p>text want.</p><p>text don't want.</p> |<p>text..| 4  | post?  |<p>text want.</p><p>text don't want.</p> |<p>text..| 5  | post? |<p>text want.</p><p>text don't want.</p> |<p>text..| --------------------------------------------------------------------------

what i'd know is, in excerpt column, how can remove after first </p> occurrence? i've been searching solution on last few days , thing i've come across regexp in sql i'm still rather new writing query commands.

any appreciated. thanks, everyone!

try this:

select      excerpt,     substring(excerpt, 0, locate('</p>', excerpt) + char_length('</p>'))       your_table

edit:

select      excerpt,     substring_index(excerpt, '</p>', 1)       your_table
