![]() ) Code language: SQL (Structured Query Language) ( sql ) The following illustrates the syntax of the CONCAT function. The CONCAT function requires a minimum of one parameter otherwise it raises an error. The MySQL CONCAT function takes one or more string arguments and concatenates them into a single string. In Microsoft SQL server, you use the addition arithmetic operator (+) to concatenate string values.īesides using spaces for string concatenation, MySQL provides two other functions that concatenate string values: CONCAT and CONCAT_WS. For example, if you use PostgreSQL or Oracle, you have to use the string concatenation operator ||. MySQL string concatenation is cleaner in comparison with other database management systems. To concatenate two or more quoted string values, you place the string next to each other as the following syntax: SELECT 'MySQL ' 'String ' 'Concatenation' Code language: SQL (Structured Query Language) ( sql ) In this short article, we have learnt how to concatenate multiple strings using concat() function.Summary: in this tutorial, you will learn various ways to concatenate two or more strings together by using the MySQL CONCAT and CONCAT_WS functions. However, please note, if any of the strings in concat() function is NULL, then the result of concatenation is NULL. SELECT CONCAT(first_name, " ", last_name,", ", cast(Age as char)) AS student_details FROM students However, if you get an error saying type mismatch, then you can always use cast(), convert() or format() function to convert the data into string before combining with other strings. Generally, concat() function will automatically convert non-string data types like integers & dates into strings before concatenation, as seen in the above example. SELECT CONCAT(first_name, " ", last_name, ", ", Age) AS student_details FROM students In the following query, we add age details after the full name, along with a comma in between. 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. MySQL provides many useful functions to work with string literals and text based columns.
