![]() ![]() ![]() A numeric argument is converted to its equivalent nonbinary string form. If the arguments include any binary strings, the result is a binary string. If all arguments are nonbinary strings, the result is a nonbinary string. The CONCAT() function returns NULL if any argument is NULL.Įxample: SELECT CONCAT('Homer', NULL, 'Simpson') AS 'Full Name' You only need to specify the separator once, and it’s used on every string that’s concatenated, therefore saving you from having to re-type it between each string. This allows you to specify a separator to be used in between each string. If you’re concatenating more than two strings, and you need a space (or other separator), consider using the CONCAT_WS() function. ![]() So if we apply this to a database, then the query might look something like this: SELECT CONCAT(FirstName, ' ', LastName) AS 'Full Name' Which may or may not be the result you’re looking for. If I didn’t add the space it would’ve looked like this: SELECT CONCAT('Homer', 'Simpson') AS 'Full Name' I concatenated the first name, the last name, plus a space. Returns a binary string, if the arguments include any binary strings. Returns a nonbinary string, if all arguments are nonbinary strings. Returns the string that results from concatenating the arguments. Note that I actually concatenated 3 strings here. MySQL CONCAT () function is used to add two or more strings. Here’s an example: SELECT CONCAT('Homer', ' ', 'Simpson') AS 'Full Name' In MySQL (and in any computer programming environment), string concatenation is the operation of joining character strings end-to-end. MySQL has the CONCAT() function, which allows you to concatenate two or more strings. The function actually allows for one or more arguments, but its main use is to concatenate two or more strings. ![]()
