What is the method to replace strings in MySQL?

You can replace strings in MySQL using the REPLACE function, which takes three parameters: the column or expression to replace the string in, the string to be replaced, and the new string to replace it with.

For example, to replace all occurrences of “old_string” with “new_string” in a certain field in the table, you can use the following statement:

UPDATE table_name
SET column_name = REPLACE(column_name, 'old_string', 'new_string');

Additionally, if you only want to search for a string and replace it in the results, you can use the SELECT statement combined with the REPLACE function.

SELECT REPLACE(column_name, 'old_string', 'new_string') AS new_column_name
FROM table_name;
