ECPG Questions

G'Day !

I am writing an application that intefaces with a POstgreSQL database thru
ECPG.

One of my queries is rather complex involving 4+ tables. One table has an
arbitrary number of items associated with a single entry on another table.
It is actually a many to many relationship. I am using a "index" table to
relate the two.

For example: I have a table that contains an id plus other information
then a second table that contains an id as a foriegn key plus an arbitray
number of data points. the two table are associated with an index table.

I want to retrieve the data and put it into a linked list of structs, the
data points in an
array inside the struct.

Is there an easy way to do this.

I was think that I would open a cursor to get the info from the first table
(which includes a column for number of data points) Then allocate an array
and open a second cursor to retrieve the data points, then put all the data
into a list element and move to the next truple.

Is this legal ? Is there a better way ?

The alternative is to get all the data in one large truple and throw away
all the repetive data returned. This seems like an unneeded headache.

comments and suggestions
