Solution 3

The query you wrote will give conversion error from varchar to int..
remove the single quotes from the date you mentioned if u want the varchar value

SQL

DECLARE @TodaysDate VARCHAR(10)
SET @TodaysDate = 12/25/2005
SET @TodaysDate = @TodaysDate + 5

Solution 1

Execute the sql on sql server query analyser.
Answer is D because you can not add string value and an integer value.

Hi,

open SQL sever then copy this code to query analyzer then execute,

Here you will get the error like.

Conversion failed when converting the varchar value '12/25/2005' to data type int.

Solution 4

Hi,

use print or select statement end of the code.

SQL

DECLARE @TodaysDate VARCHAR(10)
SET @TodaysDate = '12/25/2005'
SET @TodaysDate = @TodaysDate + '00/03/2012'
print @TodaysDate

Now you can see the result of the TodaysDate
