I am working on a database using Valentina and
RunRev. I am just learning
sql and have discovered that sql joins will be key
to a lot of my
development. So I constructed a join, which looks
like the following:
SELECT BasicLexicon.Nishnaabemwin, BasicLexicon.PoS,
Keys.Key, Keys.PoS,
Keys.SubKey, Keys.UniqueCode FROM BasicLexicon, Keys
WHERE
BasicLexicon.UniqueCode = Keys.UniqueCode
The details aren't important -- Basically, all this
is doing is getting
information from _two_ different tables in a
Valentina database, and
stitching them together. Here's my question -- Why
does this work with the
following function call:
put revDataFromQuery(,,1,myJoin,) into fld
dataset
This does exactly what I want! What puzzles me is
the fact that the
revDataFromQuery seems to require a single database
ID:
revDataFromQuery([columnDelim],[rowDelim],databaseID,SQLQuery[,varsList])
So how can this join succeed, since it's looking up
two distinct queries as
defined by the Database Query Builder, and I only
passed it the index of one
(1)? Is this a bug soon to be corrected, or am I
missing something? Thanks.

Hi Rand,
The reason why Valentina can figure it out, is that
one database can contain multiple tables. In fact, if
the tables were in separate databases, Valentina
couldn't possibly link these two tables. (*)
Hope this helped,
Jan Schenkel.
(*) except of course if you were to import one of the
tables into the other database as a temporary table,
but I digress.
