New function in DENALI SQL SERVER 2012 (CHOOSE)
Hello friends,
This is another post related to new functions in DENALI (SQL SERVER 2012).
So today I am going to discuss “CHOOSE” functions .By the name it is clear that it will choose value.
In a simple sentence you can say it array which give value according to index parameter.
Its syntax is very simple.
CHOOSE (VALUE,CHOICE1, CHOICE2….CHOICEN)
Below is example.
In the example we are passing month value in CHOOSE function and according to value it provide corresponding string value of month.
DECLARE @tblFriends AS TABLE (Prefix VARCHAR(10) ,
Fname VARCHAR(200),
LName VARCHAR(100),
DOB SMALLDATETIME)
INSERT INTO @tblFriends(Prefix,Fname,LName,DOB) VALUES('DR','Ravindra','Verma','1/1/1981')
INSERT INTO @tblFriends(Prefix,Fname,LName,DOB) VALUES('Mr','Rajul','Verma','3/3/1981')
INSERT INTO @tblFriends(Prefix,Fname,LName,DOB) VALUES('Sir','Suyash','Kokje','4/4/1981')
INSERT INTO @tblFriends(Prefix,Fname,LName,DOB) VALUES('Sardar','Ravindra','Dhariwal','2/2/1981')
INSERT INTO @tblFriends(Prefix,Fname,LName,DOB) VALUES('Pandit','Shyam','Purohit','5/5/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Shrikant','Yadav','6/6/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Sawan','Gupta','7/7/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Pankaj','Tomar','8/8/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Vaibhav','Joshi','9/9/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Vikram','Chouhan','10/10/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Subhash','Patidar','11/11/1981')
INSERT INTO @tblFriends(Fname,LName,DOB) VALUES('Vinay','Karma','12/12/1981')
SELECT CONCAT(Prefix,' ' ,FName, ' ',LName) AS ConcatName,
CHOOSE (datePart(m,DOB),'JAN','FEB','MAR','APR','MAY','JUN','JUL','AUG','SEP','OCT','NOV','DEC') AS DOBMONTH
FROM @tblFriends
so when you execute this script you will get following result.
I hope you enjoyed learning this.
ConcatName DOBMONTH
DR Ravindra Verma JAN
Mr Rajul Verma MAR
Sir Suyash Kokje APR
Sardar Ravindra Dhariwal FEB
Pandit Shyam Purohit MAY
