I have an autoincrement field (+others of coarse) in myISAM table. When I

do it with Borland C++ builder 6's TSQLClientDataSet (dbExpress) it throws
an exception that the field's value must be set. It continues

I think you are coming from the wrong angle. If you want the opposite,
you should reverse your approach. Select all the names in the projects
table, match them with names in the contacts, then filter it so you only
have the ones without a match.
SELECT p.name,p.company FROM projects p

Hello everybody,

How much work do you want done for you? Perl and Python are great apps for
writing MySQL reports, and you can output all the report to a text file,
which would be great for a reader. But as report applications, can't help

probably is a better way of doing it. Have you looked into using the
REPLACE function instead of a delete and insert. It should be faster and

I've looked through the mysql manual for information on regualar

You are inserting 6 values into 7 fields, so it fails.
You don't see the failure because you are doing an insert ignore.
You are also inserting numbers with 4 digits right of the decimal, where
you have specified 2.

You are correct that it does sound a bit rude, even when English is
your first language and you stop to think about it. However, what the
statement means is identical to The sex of the animal can be

I guess it depends on if you have a dirty mind, or, you just ignore it and
understand the point of the example. ;) lol
But yeah, could have been worded slightly different.

I believe you can do:

Heh.
the easiest way to do this is to use mysql's own 'password' function.
to add a new user use:
insert into table (username,passwd) values ('jianping',password('jian1830'))
to validate the password:
select count(*) from table where username='jianping' and

Are you referring to the data type SET or the Command SET? The manual page
you point to is talking about the data type, but usually when seen in an
insert it is the Command. I can't recall seeing the datatype referred to in
an INSERT, but maybe my brain isn't fully on yet today.
This is probably a dumb question, but are you running all the queries in
eod_stocks? I ran all the queries and they worked fine. I undotted the
select though because my database was not called eod_stocks. Since you did
not include the part where you select the database to run these queries in,

Jaime,
You should be using the DISTINCT function.
SELECT DISTINCT account, id, FROM etc.
This should give you one instant of 'account' in your SELECT output.
