Declare @Count tinyint
Declare @Count2 tinyint

SELECT @Count2 = Count(*) FROM  table where artno = @new 

If @Count2 != 0
BEGIN
    delete from table where artno = @new
END

I could not know what these lines of codes in the stored procedure in SQL Server are doing exactly.

I have looked into the definition of and use of count() after that as well not able to figure it out. Especially the = in the code confuses me a lot as well as * in the `count(*)´.

I am beginner so would like to apologize if its quite elementary question, I got to understand though.

    SELECT @Count2 = Count(*) FROM  table where artno = @new

    gets the number fo records where artno is equal to the content in your @new varaible and stores that number in the @Count2 variable.

    If @Count2 != 0
BEGIN
    delete from table where artno = @new
END

    deletes all records where artno is equal to the content in your @new varaible, if the @count2 is not 0

    BTW the @Count variable is not used in that code and is obsolete.
