SQL REPLACE Function: Replace Strings in SQL Server

In SQL Server, you can use the REPLACE function to substitute strings.

The syntax for the REPLACE function is as follows: REPLACE(string_expression, search_string, replacement_string)

In this case, the string_expression is the string expression to be replaced, the search_string is the substring to be replaced, and the replacement_string is the substring to replace it with.

Suppose there is a table named “customers” with a column named “address,” and we want to replace “Street” in the address with “Road.” This can be achieved using the following SQL statement:

Update the customers’ addresses by replacing ‘Street’ with ‘Road’.
