loop thru the list of months using t-sql statement
-
can this be done in a t-sql statement:
table 1:
operator
name1
name2
name3
table 2:
previous_month
name2
table 3:
current_month
name1
name2
i need to return the list of operators from table 1. i need to join it with the other two tables.
table2 will tell me the value for the previous month. if its null in table2 then the value of item will be 0.
if it has a matching record in table 2 then its 1.
if it has a matching record in table 3 then the value of the month is the current month and item is 1. otherwise
the value of the month is the current month and item is 0.
my problem is how can i iterate through values January to (CurrentMonth-1) so that it will return the following:
operator month item
name1 January 0
name1 February 0
name1 March 0
name1 April 0
name1 May 0
name1 June 0
name1 July 0
name1 August 0
name1 September 0
name1 October 1
name2 January 1
name2 February 1
name2 March 1
name2 April 1
name2 May 1
name2 June 1
name2 July 1
name2 August 1
name2 September 1
name2 October 1
name3 January 0
name3 February 0
name3 March 0
name3 April 0
name3 May 0
name3 June 0
name3 July 0
name3 August 0
name3 September 0
name3 October 0
thanks

It sounds like a CASE statment would work. But it would help if you could give us some sample data, your current output, and what you hope to achieve...
