String Function in SQL Server 2012

CONCAT() Function

Concat Function is new function in SQL Server 2012 this Function is very Great Function becouse in 2008 when we want to concat two name + Number we must make ++and Cast the Number to String that’s very hard today in this version we will make this operation in one and easy step . Let’s See How :

SELECT CONCAT(1, 2, 3, 4) AS SingleString
SELECT CONCAT(‘One’,1, 1.1, GETDATE()) AS SingleString
SELECT CONCAT(‘One’,2,NULL) AS SingleString
SELECT CONCAT(”,”,”,”) AS SingleString
SELECT CONCAT(NULL, NULL) AS SingleString

in old SQL Server when you want to conact Mostafa + Elmasry +1985 you write

Select ‘Mostafa’ + ‘ Elmasry’ + Cast(‘ 1985’ as Nvarchar(10)) AS My_Name

But in New Version that’s very easy see :

Select Concat(‘Mostafa’,’ Elmasry’,1985)
