How to insert more than one value into one field in the database?
-
Hi,
I need to know how to insert more than one value from a sproc into one table that has two fields..
for example i need to insert a baker
this baker... cooks...cleans....preps......and at the same time this baker has one UserID... THE table that i need to inset this info into has only two columns... userid and Jobs...
So my question is how do i do a insert like this?
thanks,
erik..

You don't. You normalise your database schema so that a single field stores a single value.
In your example use 3 tables. 1 to store details of the user. (id = 1, title = baker, name= Bob, etc)
A second table stored jobs (eg cook, clean, bake, prepare, sell) and a third is a joining table between them (eg userid = 1, jobid=1, userid=1, jobid=3)
If you have no option (ie existing database and you can't change design) then you could concatinate the values together into a comma-delimited list and store that. That option does however violate the first rule of database normalisation.

awww.. not a concatenated list...
that will be absolutely horrible to search through...I'd go for the userid + job instead, one row for each job that the userid has. This would of course mean that the PK must also be userid + job... but I think I prefer that instead of having userid + job1, job2, job3....

that will be absolutely horrible to search through...Search through? How about updating to remove a job. That goes several miles beyond horrible.
Hence the comments about normalising the database.
I was working on the assumption (probably bad) that userID was unique.

Oh, yes, you're absolutely right. The step beyond horrible is ever so short.
I too assumed that userId was unique, hence the note about userId + job must then become the PK...

ok i am lost here... what exactly is it that i should do?

Could you give us a little bit broader description of tables involved and what fields are unique?
Ideally you shouldn't put more than one value in a field (doing so violates the basic rules of relational databases), so if you give us a better idea of the overall problem, we can sugest somethng useful.

oop's... i can see that i have not asked my question correctly. (((( Ideally you shouldn't put more than one value in a field ))))) i need to insert many records into one talbe (userspecialty) that have the same userid..
so when i insert a new user into the users table...then i insert all of the userspecialty (user may specialize in one are or 20 areas....) would like to wrap this up in one querry.

This is where i need to pass in one to (how ever many) after i am able to retrieve the newly inserted user

Erik - if I've understood the requirements correctly, I think what you want to do is this...
INSERT INTO UserSpecialty SELECT @UserId, UserSpecialtyCD FROM Specialty WHERE SpecialtyName IN ('Butcher', 'Baker', 'Candlestick Maker')
**ASCII stupid question, get a stupid ANSI !!!** -
I have a form that a new user fills out decribing their business and the different areas of building they specialize in...
all of the fields that the new user fills out is one value... what i need for the areas that the user specializes in..is a way for the user to make a Multiple selection and pass that back to a stored procdure... i think i am going to need some sort of xml..
what do you think?
erik

One alternative is to have a drop-down box that displays the values from your "Specialty" table where the user can select multiple rows and then you insert based on the selection...
actually, that's what I thought you were doing when I posted that query...
**ASCII stupid question, get a stupid ANSI !!!** -
Think you mean a list box
Yes add a list box to the form, populate the values into the list box based on your Specialty table.
Make it multiselectable.
When your form gets submitted to the DB, create a loop for a count of items selected and just call your proc each time to insert into UserSpecialty.
Dont see this a SQL problem though, maybe the wrong forum
-
Here is what i finally was able to come up with.
I did use a listbox so that i can let the user make more than one slection... when i got to this part in my application i was a little dumbfounded because it never dawned on me that i would need to insert more than one record for one userid at a time...So in order to keep my app looking pro i had to come up with something...and o'll xml to the resuce...
This is not the exact piece that i have in my app; however, this is what i used to test with and build, and this works great... this will allow the user to insert as many records from a listbox as they want to..
OPENXML.... to the resuce.
