Hello,I hope this question is not too novice for this group. I have a table portfolio=# \d questions Table "questions"Attribute | Type | Modifier -----------+-------------+-----------------------------------------------------qid | integer | not null defaultnextval('questions_qid_seq'::text)optiona | text | default 'Z'optionb | text | default 'Z'optionc | text | default 'Z'optiond | text | default 'Z'optione | text | default 'Z'optionf | text | default 'Z'optiong | text | default 'Z'optionh | text | default 'Z' and other table named quizes, which contains references to the questions. Basically a quiz is composed of up to three questions. portfolio=# \d quizes Table "quizes"Attribute | Type | Modifier -----------+-------------+------------------------------------------------------quiznum | integer | not null defaultnextval('quizes_quiznum_seq'::text)question1 | integer | question2 | integer | question3 | integer | So my question is if I want to querry out a particular quiz and all its questions and question options, how can I do that in one command. I know that I could do it with a couple of loops, but I think the SQL is much more eliquent. Maybe I have my tables incorrectly set up? And suggestions? Thanks all,Daryl
