Selecting data from mysql using qt?

[lyuts]

Ok, I see. What is the location of your XAMPP installation? try to find the mysql binary there. And use the whole path (since I assume it is not in PATH) when connecting, i.e.

@/path/to/xampp/bin/mysql -D dbname -u username@

UPD: Didn't notice the location of xampp. then try (I guess it would be like this) @/opt/lampp/bin/mysql@

[doforumda]

now here it what it says
@
root@zafar-laptop:/# /opt/lampp/bin/mysql -D testTwo -h localhost -u root -p 123456
Enter password:
ERROR 1049 (42000): Unknown database '123456'
@
i am providing the right pw

[lyuts]

Try not passing -p switch. I guess you will be prompted to type in your password.
or
@/opt/lampp/bin/mysql -u root testTwo@

[doforumda]

now it output is Access Denied
@
root@zafar-laptop:/# /opt/lampp/bin/mysql -u root testTwo
ERROR 1045 (28000): Access denied for user 'root'at'localhost' (using password: NO)
@

[lyuts]

I'm sorry i just confused you with my last post.

@/opt/lampp/bin/mysql -u root -p 123456 testTwo@

I thought that mysql would prompt you but it didn't.

[Dii]

Do it this way, then it will prompt for a password:

@/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p
@

[doforumda]

i got a big ouput here but i have not seen any errors in this. when i try to post whole output this forum didnt allow me to post more than 6000 characters

[lyuts]

Cut it into pieces or use something like pastebin.

[doforumda]

ok here it is

root@zafar-laptop:/# /opt/lampp/bin/mysql -u root -p 123456 testTwo

'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect. WARNING:
options deprecated; use --disable-auto-rehash instead.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent)
--character-sets-dir=name
Directory where character sets are.

Named commands are disabled. Use * form only, or use

Hm, apparently mysql is rather strict in terms of specifying parameters. Try to follow ¤ Dii ¤'s instructions.

[doforumda]

whats Dii and where are these instructions?

[lyuts]

Here is his post.

[quote author="¤ Dii ¤" date="1286874970"]Do it this way, then it will prompt for a password:

@/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p
@
[/quote]

[Dii]

lol, don't be write only :)

/opt/lampp/bin/mysql -D testTwo -h localhost -u root -p

[Dii]

BTW if you do this, AND it's working, you end up in mysql command line interface, you can get out with 'exit'

[doforumda]

sorry i couldnt notice Dii user

[lyuts]

Wow, mysql is full of surprises. Never got those with psql. ¤ Dii ¤, does it have \q command?

[doforumda]

yes i get into mysql command line

[doforumda]

whats the reason that my database is not opening in qt?
