 that is given to the attacker about the result of the executed statement. Error messages, especially those generated by a connection API or programming language, are often quite technical and verbose and can reveal critical information, e.g., parts of the failed statement like “You have an error in your SQL syntax near '…'”. Such messages can give attackers handy information on the context the injection happens in (statement type, clause type, parentheses nesting level, etc.).
In your example a simple id=' OR '1'='1 would result in the following statement:
SELECT * FROM `mytable` WHERE id='' OR '1'='1'

With the latter expression '1'='1' all rows will get selected. An extension to this would be using a sub-query to read arbitrary data in a blind manner:
SELECT * FROM `mytable` WHERE id='' OR EXISTS (SELECT * FROM users WHERE name='admin' AND password LIKE 'a%') AND '1'='1'

Here all rows would only be selected if there exists a user admin whose password begins with a, otherwise no row would be selected. This technique is called ‘boolean-based blind’.

 Q:

Cannot execute virtualenv commands when using Python 2.7

I am trying to set up a virtual environment for a Django project, using Python 2.7. Both Python 2.7 and 3.6 are installed on my Mac.
I run the command, specifying the path to Python 2.7 virtualenv --python=/usr/bin/python2.7 venv and everything seems to work fine. However, when I run venv source/bin/activate it tells me venv: command not found.
Something is broken. I have read similar answers on Stack Overflow but nothing seems to be working. I have installed and uninstalled virtualenv with pip, tried running with superuser etc.

A:

I guess you need source venv/bin/activate. source is a command, venv is the directory your virtualenv is located in.

Such messages can give attacker handy information on the context the injection happens in (statement type, clause type, parentheses nesting level, etc .).

 With the latter construction' 1'='1' all rows will get selected. An extension to this would be using a bomber - query to read arbitrary data in a blind manner: 
 SELECT * FROM 'mytable 'WHERE id=" OR EXISTS (SELECT * FROM users WHERE name='admin' AND password LIKE' a%') AND' 1'='1' 

 Here all rows would merely be selected if there exists a user admin whose password begins with a, otherwise no row would be selected. This technique is called ‘ boolean - based blind ’.
