Please post DDL, so that people do not have to guess what the keys,
constraints, Declarative Referential Integrity, data types, etc. in
your schema are. Sample data is also a good idea, along with clear
specifications. It is very hard to debug code when you do not let us
see it.
In many years of writing SQL, I have seldom found a need for a cursor.
They usually run 1-2 orders of magnitude slwoer than a relational
solution.
When someone uses one, it is generally becasue they are mimicing a
magnetic tape file system, and probably violating the basic principle
of a tiered architecture that display is done in the front end and
never in the back end. This a more basic programming principle than
just SQL and RDBMS.
Finally, id_position is not an ISO-11179 data element name and it makes
no sense. Identifier of what? Position of what? You have two
adjectives without a noun. But I bet you mant it to be PHYSICAL
location because you are mimicing a magnetic tape file system, instead
of using SQL for an RDBMS.
What is your real problem? Show us and perhaps we can help you.
