![]() If you want to concatenate columns with comma then you can add it within quotes, as an argument in concat() function, as shown below. Here is an example where we don’t alias the concat() function SELECT CONCAT(first_name, " ", last_name) FROM students If you don’t provide an alias to the concat() function then column name of result will be the entire concat() function as defined in the SQL query. SELECT CONCAT(first_name, " ", last_name) AS Full_name FROM students Here is an example to concatenate first_name and last_name column with a space in between to obtain full name. Each string can be a literal within single/double quotes or a column name. In the above function, you need to specify the strings to be concatenated, in a comma-separated manner – first string as first argument, second string as second argument, and so on. Here is the syntax for concat() concat(string1, string2. Here are the steps to concatenate strings in MySQL.Ĭoncat() is the most common function to concatenate strings in MySQL. We will use concat() function to concatenate strings in MySQL, since it allows you to concatenate literals with other literals or with columns, and it also allows concatenation between only columns, even if they have different data types. In this article, we will learn how to concatenate strings in MySQL, with different use cases. They may be of same of different data types. Sometimes you may need to concatenate strings in MySQL. The syntax for the CONCAT function is as shown below: CONCAT(Column 1, column 2.MySQL provides many useful functions to work with string literals and text based columns. ![]() The CONCAT function can concatenate or combine values from multiple columns into a single column. VALUES given query returns all data from the student table: SELECT * FROM student order by sid Ĭoncatenate Columns Using the CONCAT Function in MySQL Here, we insert sample data values into the student table for the demonstration. CREATE TABLE student (sid INT, firstname VARCHAR(20) NOT NULL, lastname VARCHAR(20) NOT NULL, email VARCHAR(55) NOT NULL) The following script creates a table student with four columns ( sid, firstname, lastname, and email). ![]() In contrast, the CONCAT_WS() function returns the NULL value only if the separator is NULL. There is another significant difference between these functions in that the CONCAT() function returns the NULL value if any of the arguments are NULL. These two functions differ because the CONCAT_WS() function works along with a separator between strings, whereas the CONCAT() function does not allow the use of separators. Two different functions can be used to accomplish this task.īoth CONCAT() and CONCAT_WS() functions concatenate two or more strings. Similarly, if an address is split into multiple columns in a database and you want it as a single address, including city, state, and country in your application, then the CONCAT function would be very useful. If you have two separate columns in the database as first name and last name and want to show value in both the columns as a single string full name, you can use one of the two given approaches to accomplish your task. It is possible to simplify the above procedure by concatenating the values as you select rows from the Database Table. This task can easily be accomplished pro-grammatically by selecting fields from a MySQL table and storing their values into one variable after concatenating their values. This article will show you various ways to concatenate data of two columns in MySQL. Concatenate Columns Using the CONCAT_WS Function in MySQL.Concatenate Columns Using the CONCAT Function in MySQL.
