#MYSQL CONCAT A MINIMUM PLUS#

In MySQL, you can easily concatenate strings by specifying them within single or double quotes and separating them with spaces. The execution of the above query statement gives the following output with expected strings:Īn alternative way of concatenating strings in MySQL: We can use the Concat function to do so in the following query statement: SELECT CONCAT('Word ', word, ' means that ', meaning) AS 'Meaning of Words' FROM dictionary Now, we have to concatenate the column values such that the resultant string will have the strings in the format Word “word column string” means that “meaning string”. Let us retrieve the inserted records: SELECT * FROM dictionary The execution of the above query statement shows the following output: ('panache', 'a tuft or plume of feathers', 'feather collection') ('flair', 'stylishness and originality.', 'originality'), ('knack', 'an acquired or natural skill at doing something.', 'natural skill'), ('thesaurus', 'a reference tool which shows groups of words that have similar meanings', 'representation of groups of words that have similar meanings'), ('polysemy','the fact that some words can have more than one meaning', 'multiple meaning words'), ('lexicography', 'the job or skill of writing dictionaries', 'writing dictionaries'), ('etymology', 'the study of the origins of words the origins of a particular word', 'the study of the origins'), ('connotation', 'an additional idea or emotion that a word suggests to you', 'emotions attached to words' ), ('antonym', 'a word that means the opposite of another word', 'an Alternative name'), Let us insert some records in the table using the following query statement: INSERT INTO 'dictionary' ('word', 'meaning', 'description') VALUES We will use the following table to create the table: CREATE TABLE 'dictionary' ( Let us create a dictionary table containing three columns: word, description, and meaning. We can even concatenate the values stored inside the variables and column values. The execution of the above query statement gives the following output as NULL because even a single NULL parameter can result in the output string being NULL: We will try concatenating “Welcome”, “To “, “EDUCBA” and NULL parameters using the following query – SELECT CONCAT('Welcome', 'To ', 'EDUCBA ', NULL) Let us try concatenating the strings with a NULL value as one of its parameters in the Concat function. The execution of the above query statement gives the following output: For this, we will use the following query statement – SELECT CONCAT('EDUCBA', 'IS A GREAT ', 'PLATFORM ', 'TO EXPAND ', 'YOUR HORIZONS ', 'OF LEARNING') AS 'Final String' Now, we will concatenate the string values “EDUCBA”, “IS A GREAT “, “PLATFORM “, “TO EXPAND “, “YOUR HORIZONS” and “OF LEARNING” using the Concat function in MySQL. We can observe from the output that an error is raised, saying that an incorrect number of parameters were supplied to the Concat function. The execution of the above query statement gives the following output –

We will execute the following query statement – SELECT CONCAT() A numeric argument is converted to its equivalent nonbinary string form.Let us first try to execute the MySQL Concat function without passing any parameters and see the output which is arisen. 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. Note that I actually concatenated 3 strings here. 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.
