Hi Everyone
I am now familiar with connecting with MySQL using Visual Basic 6 and ADO. I am
about to start a new project which must connect to a customer's MS SQL Server
2005 installation.
How safe/unsafe is my assumption that as far as SQL strings and ADO connections
are concerned 'if it

- SQL Server doesn't support LIMIT clause;
- Don't use quotes for numerical values as it works on MySQL only;
- In GROUP BY clause, list all not aggregated columns you are selecting;
- Use
What about
DROP TABLE IF EXISTS TableName
and

and
ALTER TABLE TableName ADD COLUMN DeliveryNoteNumber INT NOT NULL DEFAULT 0

There are also differences in data types.

Hello,
This is a long post, my apologies.
I have been working on migrating a database from MS SQL to MySQL for about 1
month now and am at a point where I can start running some tests to see how
they compare. I'll provide a little background to help you out.
The MS SQL database is 120million

Chris,
We run a large data warehouse with tables similar to yours. We basically gave up on
indexing and the overhead involved and just tablescan. The key is to partition the
data using a concept called Merge Tables. However, since we currently use Oracle,

Nestor, thanks for your question.
The platform will actually be dictated by the SQL engine, not the
other way around, which is more typically the case. If we go with
MS SQL Server, we'll build a separate host, NT I would guess, to
host it. I'm only responsible for Unix and Linux boxes here, so

very nicely without them. Why are you different?

i tend to think the consultant really just read something that microsoft
sent him. it doesn't sound like he's qualified to suggest one database
or another.
We've been usinf mysql for a year now. We use InnoDB tables, which give
us primary key/foreign key constraints and transactions.

Except that they may be battling for resources: no.
You can also adjust the MS SQL 2K settings to have a maximum memory
