Question

I’m creating a SQL query string in android code which goes as follow:

SELECT strftime('%m', DATE) "MONTH", strftime('%Y', DATE) "YEAR" FROM EXPENSES group by month, year ORDER BY MONTH DESC, YEAR DESC

I know that if I want to get " I write just ' inside a string,
but what if I want to get that single char '?

Could anybody properly enclose this query in quotes, so it works fine?

Answer 1

Your question seems a bit confused as to what you need to escape and when. This should cover it:

• To escape a single quote in SQL, you just double it up.

  'an escaped single quote '' like that'
  

• In Java, you just use double quotes around the outside.

  "a single quote ' like that"
  

• To escape the double quotes in Java, use a leading slash \ as so:

  "SELECT strftime('%m', DATE) \"MONTH\", strftime('%Y', DATE) \"YEAR\" FROM EXPENSES group by month, year ORDER BY MONTH DESC, YEAR DESC"
