Answer 2

run this command in command line:

mysql> show variables like 'version_compile_machine';

then you get something like this:

+-------------------------+-------+
| Variable_name           | Value |
+-------------------------+-------+
| version_compile_machine | i386  |
+-------------------------+-------+
1 row in set (0.00 sec)

and then please check this: http://www.redhat.com/archives/rhl-list/2006-October/msg03684.html

you'll see that i386/i686 are 32 bit, and x86_64 is 64 bit.

Hope this helps.

Answer 3

You can use version() :

SELECT version();

See more information here:)

Answer 4

Running the command-line MySQL client:

mysql> select version();

OR

mysql> \s

which is an alias for:

mysql> status

Answer 5

You could try the command: (no login needed)

mysql -V

Answer 6

To know your Mysql bit architecture please follow this step. Open Mysql console from phpmyadmin

Now after entering password type this command

show global variables like 'version_compile_machine';

if version_compile_machine = x86_64 then it is 64 bit

else 32 bit.

Answer 8

I was searching for this also (core dump issues connecting to mysql) and it seemed none of the above answers properly answered the question: eg mysql version info doesn't include the build type 32or 64 bit.

found this capttofu: Do I have a 32-bit or 64-bit MySQL? captoflu which uses a simple "file" command to tell what build youre running, in my case.

BensAir:~ Ben$ /usr/local/mysql/bin/mysqld --verbose --help
file /usr/local/mysql/bin/mysqld
/usr/local/mysql/bin/mysqld: Mach-O 64-bit executable x86_64

Answer 9

No login is needed (OS X 10.11).

$ /usr/local/mysql/bin/mysqld --version

Answer 10

Use @@version server variable.

select @@version;

This is what I get on my server:

mysql> select @@version;
+-----------------+
| @@version       |
+-----------------+
| 5.0.67-0ubuntu6 |
+-----------------+
1 row in set (0.00 sec)

Hope it helps.

Here's a list of all server variables .
