return previous ID
I have a table like below
ID Product_ID
1 1001
1 1002
1 1003
1 1004
2 1008
2 1009
I am trying to write a query that return a previous product number based on the ID and productId that will be provided as parameters
For example, if I put 1 and 1002 , the query should return 1001
if i put 1 and 1004 then it should return 1003
if i put 2 and 1008 m then it should return 0 because it does not have a previuos product ID
what is the best way to do this SQL 2005?
