Demo SQL Server Database
In this tutorial on REPLACE() function, we will use the following table for examples.
To create this table in your system, you have to run the below query:
Query:
--to create the table
CREATE TABLE [w3wiki]
(
[id] [int] UNIQUE,
[name] [varchar](20),
[course] [varchar] (50)
) ON [PRIMARY]
--to insert values to the table
INSERT INTO w3wiki ([id],[name],[course])
VALUES (1, 'Vishu', 'Python Self Paced');
INSERT INTO w3wiki ([id],[name],[course])
VALUES (2, 'Neeraj', 'Java Self Paced');
INSERT INTO w3wiki ([id],[name],[course])
VALUES (3, 'Aayush', 'SQL Self Paced');
INSERT INTO w3wiki ([id],[name],[course])
VALUES (4, 'Sumit', 'Java Self Paced');
INSERT INTO w3wiki ([id],[name],[course])
VALUES (5, 'Vivek', 'Java Self Paced');
SQL Server REPLACE() Function
SQL Server is a strong relational database management system (RDBMS) developed to manage large data efficiently. In SQL Server, the REPLACE() function is used to modify or replace a substring within a given string. Taking about the real word uses, the REPLACE() function is vastly used in data processing tasks such as data cleaning. It is also used for data masking purposes.
In this article, we are going to deep dive into the uses and implementation of the REPLACE() function. We will explore various examples along with their respective explanations.
