If you want a ‘phrase,’ you need to add spaces dividing separate words in the phrase: SELECT CONCAT('MySQL ','is ','RDBMS') AS Result The above syntax concatenates strings without a space, and you get only one word. Note that in the following example we are also providing a name for a new column that will display the result: SELECT CONCAT('My','SQL') AS 'Result' The simplest example is joining different pieces of text together to combine a new word or phrase. Usually, we use CONCAT() with the SELECT statement. In this case, the query will throw an error. However, you can’t execute CONCAT in MySQL without providing at least one expression. You can add as many expressions as you need. Where expression_1, expression_2, expression_n stand for the strings you are combining. The syntax for the CONCAT function is as follows: CONCAT(expression_1,expression_2.expression_n) However, in MySQL, the syntax is simpler and more accurate. It is a regular SQL function also present in Oracle, SQL Server, and PostgreSQL. The CONCAT function is not unique to MySQL databases. This article will explore the syntax and usage of the CONCAT function in MySQL to help you understand and master it excellently. Besides, it saves you space, as several strings become one item to address. CONCAT will let you do this job with one straightforward SQL statement. Your goal is to retrieve data and present it in a format suitable for reading. Why is it necessary to master? Assume you need to perform the data selection from several columns of a large table. ![]() ![]() In MySQL, the CONCAT function takes strings from different cells and joins them together in one cell, thus creating a new string.
