MySQL error code 150: Foreign key constraint is incorrectly formed
What does table1 look like?

Yeah I used the mysql_error and it returned Can't create table
'.\website\table2.frm' (errno: 150). So what does that say?

Perhaps you don't have permissions to create tables?
It would have been much clearer if your script was like this:
$result=mysql_query($your_create_table_statement);
if($result){ printSuccessful;}
else {print Unsuccessful: .mysql_error()}

Hi guys,
Please can anyone
I suppose the problem is that table1.table1_id and table2.table1_id are
of different types. The first one is INT UNSIGNED and the second is just
INT.
abdulazeez alugo wrote:
Table1 is as below:
CREATE TABLE table1(table1_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
PRIMARY
What about source?
use foobar;
source some/dir/file1.sql;
source some/dir/file2.sql;
...
Though, your solution is much simplier.

I think you meant ORDER BY `registers`..

I´ve got a page where a ought to get 20 registers in ramdom order but i want
to display it in an alphabetical order.
Someone knows if there is a way to get that 20 random registers in
alphabetical order?

SORT BY
.
Index cardinality is 81 while table contains over than 12 millions of
different values.
I've tried recreating indecies but this didn't help.
I couldn't find anything relevant in documentation.
How should I create index on MERGE table?
Thanks in advance!

Why not:
SELECT * FROM `sav00_sava0400_dbf`
emissao BETWEEN '1999-12-01' AND '2000-12-31'
?? ;)
`sav00_sava0400_dbf` WHERE `emissao` BETWEEN '1999-12-01

You were right. There was a bug. Upgrading to mysql 4.1.20 solved my
problem.

an OPTIMIZE TABLE command every few hours, took a couple of
seconds each time, and performance stayed good.
Thanks for advice. I think I should I give this a try.. :)

Hi, Brian!
First of all I think next time you should better attach your database
structure. It'll be much easier to understand your problem if you will...
Maybe you're asking for something like this:
SELECT project_name, elecremain, controlremain, otherremain, elecremain
+ controlremain +
)

Good day!
Can you be more concrete? I believe nobody in this list can read your
thoughts.
What tells mysql? What do you see in logs?

As I said before, you can use something like:

FYI,
Nuno is correct you cannot see the password in the 'ps' and my scripts
