RE: ADVICE: Best way to store multi values

["Cal Evans" <cal@xxxxxxxxxxxx>]

you need a join table between the two tables. It would contain the primary
keys of both tables. This way for any given staffID, you could have 0-n
records that contain staffId & subjectTitles_id.

To get all the subjectTitles for a given staff you would

Select * from staff_subjectTitles where staffId = <thePersonToLookFor>;

you can use where clauses to join in the Staff and SubjectTitles tables to
that select as well to gather them all into one select.

Subject: ADVICE: Best way to store multi values


Hi,

I have a table called staff which currently has a column called
subjectTitles_id which is the type INTEGER.

I have another table called subjectTitles which contains 12 subject
titles.

So that is how a member of staff is assigned a subject.

Trouble is I need to be able to assign a multiple number of subjects to
anyone member of staff.

The method I thought to use was change staff.subjectTitles_id from
INTEGER type to CHAR type and store a string of CSV numbers which
correspond to the id's of the table subjectTitles, e.g.:-

1;2;7;10

Is this the way?

It seems quite ungraceful.
