public @interface SqlEvenQuotes
Denotes a String that contains either zero or an even number of unescaped single quotes —
i.e., there must be either zero or an even number of
' characters in a SqlEvenQuotes
String that are not preceded immediately by another ' character. (Thus, all SqlEvenQuotes
Strings ultimately contain an even number of ' characters.) A SqlEvenQuotes String is
syntactical to be passed to query execution methods and is guaranteed not to affect whether
subsequent concatenations are interpreted as SQL command code or as SQL query values.
Common use cases include: SQL query fragments, such as "SELECT * FROM"; properly sanitized user input; and complete SQL queries, such as "SELECT * FROM table WHERE field = 'value'".
