Addition of two numbers

[sonia.sardana]

1) DECLARE @num1 int , @num2 int
Above statement declares two variables num1 and num2.

I want the addition of two numbers--
SET @num1=10
Error-Must declare the scalar variable "@num1".

2) DECLARE @num1 int =10, @num2 int= 20
is it possible to initialise the variables in the declaration as in the above case.

1) are you saying that you have these 2 lines of code

DECLARE @num1 int , @num2 int
SET @num1=10
 

and you are getting this error
Error-Must declare the scalar variable "@num1".

if so then I am staring and staring at the lines and I can't for the life of me see anything wrong with them. The error is saying you havn't declared the variable @num1

Where have you written those two lines? In a stored proc, In query analyser or where ???

2) No, I dont think so. But try and see, you will get an error if you can't

Query Analyzer......
Error is there u can check it out by executing it ......

Triggers are also known as Stored procedures na........

DECLARE @num1 int , @num2 int
SET @num1=10
 

Nope, it works fine for me in query analyser ???

In SQL Server 2000,Query Analyzer and Enterprise Manager are different.
But in SQL Server 2005,there is only one window where on the LEFT HAND SIDE,u r able to view all ur tables, and on the RHS,u write query.


U R working on SQL 2000 or 2005??

I m working on SQL Server 2005.

I have not had the pleasure of using SQL 2005 as yet, I use 2000.

Click New Query. Paste your code on the query window. Click execute (or press F5)
