Now, we will concatenate FirstName and LastName to get FullName and City, State and PinNo to get Address using CONCAT Function. So, the Student table is : Select * From Student StudentId Student(FirstName, LastName, Class, City, State, PinNo ) Now inserting some data to the Student table : INSERT INTO To demonstrate create a table named Student. SELECT CONCAT('geeks', 'for', 'geeks', NULL) AS ConcatenatedString Įxample-4 : In this example we are going to concatenate string between column of a table. SELECT CONCAT(19, 10, 5.60) AS ConcatenatedNumber Įxample-3 : Concatenating string which includes a NULL String using CONCAT Function. SELECT CONCAT('geeks', 'for', 'geeks') AS ConcatenatedString Įxample-2 : Concatenating numeric string using CONCAT Function. Example-1 : Concatenating 3 string using CONCAT Function. If the argument is numeric, it is converted. 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. If any of the input string is NULL then it returns NULL. MySQL CONCAT () function is used to add two or more strings. Returns : It returns a new string after concatenating all input string. : The input string which we want to concatenate. Parameter : This method accepts N argument.

Note that in MySQL, you will need to enable the pipe concatenation operator first. If you’re using SQLite, this is your only option. Most RDBMSs include a string concatenation operator that concatenates its operands. SQLite and Oracle don’t have a CONCAT_WS() function, but they do have a string concatenation operator (see below).
RDBMSs that have a CONCAT_WS() function include MySQL, MariaDB, SQL Server, and PostgreSQL.
In such cases, you only need to specify the separator once.
This function can be particularly useful if you have a lot of strings to concatenate: SELECT CONCAT_WS(', ', 'Red', 'Green', 'Orange', 'Blue') This function allows you to specify a separator that will be used to separate all concatenated strings.Įxample: SELECT CONCAT_WS(' ', 'Bangkok', 'Breaking') The CONCAT_WS() FunctionĪnother way to include a space between the strings is to use the CONCAT_WS() function. SQLite doesn’t include a CONCAT() function, but it does have a string concatenation operator (see below). RDBMSs that have a CONCAT() function include MySQL, MariaDB, SQL Server, Oracle, and PostgreSQL. With this function, if we want to include a space between the strings, we’d need to either add a space to one of the strings, or include a space as a separate argument: SELECTĬONCAT('Bangkok ', 'Breaking') AS "Option 1",ĬONCAT('Bangkok', ' ', 'Breaking') AS "Option 2" Generally, non-string arguments are converted to a string before the concatenation occurs.Įxample: SELECT CONCAT('Bangkok', 'Breaking') Most major RDBMSs provide a CONCAT() function for concatenating its string arguments. And there’s also a string concatenation operator, which allows us to concatenate its operands.īelow are examples of each method.There’s also a CONCAT_WS() that allows you to specify a separator that separates the concatenated strings.There’s the CONCAT() function, which concatenates its arguments.Most of the major RDBMSs provide several options for concatenating two or more strings.
