An attacker has determined a web application is running the SQL command shown below. What could she enter for VALUE to get a list of all email addresses in the employee table and avoid syntax errors?

Entering ' or 1=1;-- transforms the executed query into: select email from employee where name = '' or 1=1;-- '; the leading apostrophe closes the open string literal in the WHERE clause, 'or 1=1' creates a condition that is always true causing all rows and thus all email addresses to be returned, and the -- SQL comment marker causes the database engine to ignore the trailing apostrophe from the original query, preventing a syntax error.

' or select email from employee would produce a syntax error because placing a bare SELECT statement after OR in a WHERE clause requires a valid subquery form with parentheses, and the original trailing apostrophe from the query would remain uncommented.

or select email from employee lacks a leading apostrophe to break out of the open string literal, so the entire input is interpreted as the literal string value being searched rather than injected SQL syntax.

or 1=1 does not begin with an apostrophe to escape the string context, so the input is treated as a literal string value within the surrounding quotes rather than executable SQL logic.
