SQL SERVER: REPLACE FUNCTION

This SQL Server tutorial explains how to use the REPLACE function in SQL Server (Transact-SQL) with syntax and examples.

DESCRIPTION

The SQL Server (Transact-SQL) REPLACE function replaces a sequence of characters in a string with another set of characters, not case-sensitive.

The syntax for the REPLACE function in SQL Server (Transact-SQL) is:

REPLACE( string1, string_to_replace, replacement_string )

string1

The source string from which a sequence of characters will be replaced by another set of characters.

string_to_replace

The string that will be searched for in string1.

replacement_string

The replacement string. All occurrences of string_to_replace will be replaced with replacement_string in string1.

The REPLACE function can be used in the following versions of SQL Server (Transact-SQL):

SQL Server 2014, SQL Server 2012, SQL Server 2008 R2, SQL Server 2008, SQL Server 2005

Let's look at some SQL Server REPLACE function examples and explore how to use the REPLACE function in SQL Server (Transact-SQL).

For example:

SELECT REPLACE('mindSforest.com', 'S', '3');
Result: 'mind3fore3t.com'          (both s and S are replaced by 3)

SELECT REPLACE('MINDSforest.com', 'Minds', '1234');
Result: '1234forest.com'

SELECT REPLACE('mindsforest.com', 'i', '123');
Result: 'm123ndsforest.123om'

SELECT REPLACE('Minds Forest', ' ', 'B');
Result: 'MindsBForest'
