Hi John,
Just do a normal join as you would, for the second table reference it in
this fashion, <databasename>.<tablename> as xyz. Here is an example that
I've used myself
use test;
SELECT
s.name,
c.Street_addr_1,
c.Street_addr_2,
c.Town,
c.State,
c.PostCode,
SUM(s.tot_sales) as t_sales
INTO OUTFILE "./cardfile.csv"
FROM
sales s
INNER JOIN lcscreative.contact c
<------------------------------------------------------------ *
ON CONCAT(c.Contact_first_name, ' ', c.Contact_last_name) =
s.name
WHERE
c.Country = "Australia" OR c.Country IS NULL
GROUP BY
s.name
ORDER BY
t_sales
DESC
LIMIT 149;
Check the *, this references another database/table

Subject: Re: Import Table?
Sorry to bother you once more on this David, but I am having trouble
figuring out how to run a query on tables in two different databases. I
normally use
/usr/local/mysql/bin/mysql -h localhost -u username -ppassword -D
databaseName -N -e SELECT ...
as the initial string of the query. However, this only references one
database. How can I issue a query over two tables, one in each database?
Thanks,
John

Aha, that's it! I didn't think about the fact that you can run
queries
on tables in multiple databases in that manner.
The end result is exactly the same.
You made my day. Thanks!

Hi John,
I would probably create a temporary database, use this,
dump all the
tables into that and then use only the table that you
want, followed
by
a drop database. It would be a bit difficult to strip
out one table
AFAIK. I can't see anything in the mysql client options.
eg. mysql -u root -p <new databasename> <./.sql file
If you are embedding this into the app, is this perl or
similar? You
can
either do a create tempdatabasename or use the test
database that
seems
to be created by every mysql installation and just do a
mysql -u root
-p
test <./.sql file
Your comparisons can refer to permanent.tablename and
temp.tablename.
They will be logically and physically separate. eg. you
can JOIN etc.
so
long as you have the permissions.
Sorry I can't be of more help.

David,
I should probably just give the big picture of what I
need to
accomplish. Here it is:
I am on Mac OS X.3.
The sql file was dumped from the same database at an
earlier date
using
mysqldump.
The database has 6 tables in it, one of which is the
table I want to
access -- 'theTable'.
The end goal is to load 'theTable' from the dumped sql
file into a
temporary table on the server in order to do some
comparisons between
'theTable' currently in the server and 'theTable' from
the sql file.
I am embedding these mysql commands into my MAC OS X
application's
code, so cutting and pasting data is not relevant to my
situation.
Thanks for sticking with me on this!

Hi John,
Personally, I'd just do a cut and paste job on
the .sql file unless
it
is too unmanageable. Not knowing your platform,
and being a unixy
type
person, I would use sed or grep to strip out the
lines that I need
and
then plonk them straight into another file. I
don't know how you
could
accomplish that on a Windows platform.
I hope I haven't misunderstood, is the .sql file
come from another
MySQL
database or is this from a SQL server machine or
similar? My
interpretation of a .sql file is something akin
to that created by
mysqldump eg. a text file that has a number of
SQL statements in it
allowing you to recreate the table by using this
as input.
You can also use

Thanks for the response, David. How about if I
want to import all
the
entries from one specific TABLE within that sql
file into a table
with
identical columns on my MySQL server? Is there a
way?
Thanks,
John

Hi John,
If it is a ".sql" file, with all
appropriate SQL statements already
in
place then you only have to do the
following
$ mysql -u xxxx -p databasename <.sql
file
This will process all appropriate
statements in the file.

Subject: Import Table?
Is there a command that will load in all
of the data from a table
within a database ".sql" file on disk?
The only import option I am
seeing is "LOAD DATA INFILE" which
requires a text file already
exported to disk. How about a way to
load in the table data
directly
from the database file?
Thanks,
John
