OUTER JOIN with multiple tables and a plus sign?

I am trying to select specific columns from multiple tables based on a
common identifier found in each table.

For example, the three tables:

PUBACC_AC
PUBACC_AM
PUBACC_AN

each have a common column:

PUBACC_AC.unique_system_identifier
PUBACC_AM.unique_system_identifier
PUBACC_AN.unique_system_identifier

What I am trying to select, for example:

PUBACC_AC.name
PUBACC_AM.phone_number
PUBACC_AN.zip

where the TABLE.unique_system_identifier is common.

For example:

--------------
PUBACC_AC
=========
unique_system_identifier name
1234 JONES

--------------
PUBACC_AM
=========
unique_system_identifier phone_number
1234 555-1212

--------------
PUBACC_AN
=========
unique_system_identifier zip
1234 90210

When I run my query, I would like to see the following returned as one
blob, rather than the separate tables:

--------------------
unique_system_identifier name phone_number zip
1234 JONES 555-1212 90210
--------------------

I think this is an OUTER JOIN? I see examples on the net using a plus
sign, with mention of Oracle. I'm not running Oracle...I am using
Microsoft SQL Server 2000.

Help, please?

P. S. Will this work with several tables? I actually have about 15
tables in this mess, but I tried to keep it simple (!??!) for the above
example.

Thanks in advance for your help!

Who actually BUYS the cr@.p that the spammers advertise, anyhow?!!!
(Rhetorical question only.)You do the following:

SELECT PUBACC_AC.Name + PUBACC_AM.Phone_number + PUBACC_AN.zip
FROM PUBACC_AC
INNER JOIN PUBACC_AM
ON PUBACC_AM.unique_col = PUBACC_AC.unique_col
INNER JOIN PUBACC_AN
ON PUBACC_AN.unique_col = PUBACC_AC.unique_col

That's it - you do inner join, if you want only those records, for which
unique_col value exists in all 3 tables.
Or, if you replace "INNER JOIN" with "FULL JOIN", which is the same as OUTER
JOIN in Oracle, you will get
as meny records as number of unique_col values.

Thats it!

Hope it helped,

OUTER JOIN plus split? - how to?

Hi,

I have two tables.. one has a list of the UK postcodes.. well..it's actually the districts..

so it's the first two three or four characters (basically all UK postcodes are one or two letters.. then one or two numbers.. then a gap.. and then some more info)

So my first table has everything "before the gap" in seperate records.

My second table is full of exact postcodes.. so everything before and after the gap.

What I need to do is.. for each "full" postcode I have... strip it down so I get it formatted to everything before the gap.. and then find out how many of those I have...

This is also complicated because many of the "full postcodes" don't have the gap.

so if I have:

er56 7tr
fr2 4tg
er567tr
po3 8ty

I would want results of:

er56 - 2
fr2 - 1
po3 - 1

One I have that, I can bring in the second table with all of the parcial postcodes to do an OUTER JOIN and get the postcodes where I DONT have any results.

I know that's pretty complicated, so I'm stuggling a little!

sO i need to get the first "X" amount of characters out of a db value (it could be two values.. could be up to four- first one or two will be char, second one or two will be numeric), then do a count.

Can anyone help?

Just to help clarify:

If I was doing this ASP I would write it as:

get first value from string
- add to output string

get second value from string
- add to output string

get third value
If numeric - add to string
If not - stop loop

get fourth value
If numeric - add to string

If not - stop loop

ok thought of an easier way - but still need help.

In my SELECT clause, need to have a variable which is gathered by the length of the postcode string.. so:

1) - Remove any spaces in string
2) - Check length
3) - If length = 5 then postcode = first 2 chars in string
4) - If length = 6 then postcode = first 3 chars in string
5) If length > 6 then postcode = first 4 chars in string.

Any ideas?
