Replacing and removing substrings

The REPLACE() function is a versatile function that allows you to replace or remove characters from a string. The syntax is as follows:

REPLACE(fieldName, 'searchFor', 'replaceWith')

Where fieldName is the field or string being updated, searchFor is the characters to be replaced, and replaceWith is the replacement substring.
