This article mainly introduces the realization method of replacing letters in mysql database, which has certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

In mysql, you can use the replace function to replace letters, with syntax such as "mysql > UPDATE `de` SET body = REPLACE (body,','');".

Mysql replacement string

The replace function in mysql directly replaces a specific string in a field in the mysql database, and no longer needs to write its own function to replace it, which is very convenient to use. Mysql replacement function replace ()

UPDATE table_name SET field_name = REPLACE (field_name, 'from_str',' to_str')

Description:

Table_name-the name of the watch

Field_name-Field name

From_str-- string to be replaced

To_str-- replaced by a string

For example:

Mysql > UPDATE `dede` SET body = REPLACE (body,',')

This function is multi-byte safe, which means you don't have to worry about Chinese or English characters.
