For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Query A Different Database?

Posted by patterj (patterj), 24 May 2005
I would like to query a table from a different database, but not sure how to do it. I know in SQL Server, you can do this using ".." ex:

select table1.field1, table2.field2
from database..table1, table2
where table1.field1 = table2.field2

I was hoping there was a way to this in MySQL. I don't believe it supports the syntax listed above.

I'm sorry. I answered my own question. Turns out all tables can be accessed using this logic:

database.table.field

ex:
select database1.table1.field1, table2.field2
from database1.table1, table2
where table1.field1 = table2.field2
