SQL REPLACE Multiple Strings: Nested Function Guide

In SQL, the REPLACE function can only replace one piece of content. If you want to replace multiple pieces of content, you can use multiple nested REPLACE functions or implement other methods.

Here is an example of replacing multiple contents using multiple nested REPLACE functions.

SELECT REPLACE(REPLACE(column_name, 'content1', 'replacement1'), 'content2', 'replacement2') AS replaced_column
FROM table_name;

In the example above, column_name is the name of the column to be replaced, ‘content1’ and ‘content2’ are the content to be replaced, and ‘replacement1’ and ‘replacement2’ are the content to replace them with.

If the content to be replaced is complex or there are a large number of replacements needed, it may be more suitable to use regular expressions to achieve the replacements. The level of support for regular expressions may vary among different database management systems, so please make syntax adjustments according to the specific database management system.
