SQL How To

• Posted by cklester <cklester at yahoo.com> Sep 03, 2005

If one of my fields in a database is a sequence like {1,2,5} and those numbers
are references to unique IDs in another table, how would I get a field from
the other table using those reference IDs (that is, what's the SQL)?

For instance
person table (1 record):
   unique_id:1
   name:cklester
   fruits:{1,2,5}

fruits table (5 records):
   unique_id:1
   name:apple

   unique_id:2
   name:orange

   unique_id:3
   name:pear

   unique_id:4
   name:banana

   unique_id:5
   name:kiwi

So my query would return {"apple","orange","kiwi"}

Should I do away with the sequence field and create a new table like so:

prefs table (3 records):
   unique_id:1
   person:1
   fruit_pref:1

   unique_id:2
   person:1
   fruit_pref:2

   unique_id:3
   person:1
   fruit_pref:3

Thanks!
