Hi sqlite-users@sqlite.org,
I use sqliteODBC 0.68 + ADO and SQLite 3.3.6.
I try executing sql:
select t1.field1 as field1, t2.field2 as field2 from table1 t1 left join
table2 t2 on
(t1.id=t2.refid)
and I receive the message on a mistake "no such column: t1.field1(1)"

Thanks for the suggestion.
I wasn't aware that the prepare statement gained you that much for one-table
select queries.
I use it for multi-100k inserts (along with trans.) and it saves quite a bit
of time.
This is my sql for the present problem:
select * from (select f1, f2, f3, f4,
f5

Thank you for your thoughts.
To be clear, the 'optimize for speed' setting in MY release is actually
slower than MY debug version - I know nothing about Ralf's settings.
That issue is separate from SQLiteSpy - I didn't mean to conflate them.
And the issue is not which version of VS I'm

Two ways to do this:
SELECT rowid FROM table ORDER BY rowid DESC LIMIT 1;
SELECT max(rowid) FROM table;
Yes, but neither one of those would be as fast as this query, true?
SELECT rowid FROM table LIMIT 1

The VC6 compiler is from 1998. The VC 7.1 or 8.0 compilers produce better
compilations. I'm certain any Borland or GNU compiler of the past 3 years
would also produce better assembly than VC6. And if somebody has their hands
on a PathScale or Intel compiler, please post some benchmarks!

Write it out in SQL and read in the SQL. A bit clumsy, but simple.

Sqlite is driven by SQL, so you just use SQL like any other SQL database.
