Question

what is the difference between ‘anything’ and “anything” in sqlite database?
As far i have understood, single quotes are used to denote strings while double quotes are for keywords.
But, i have used column_name="value" as where clause in a query and database accepts that query. why?
thanks..

Answer 1

from the sqlite webpage;

http://www.sqlite.org/lang_keywords.html

If a keyword in single quotes (ex: ‘key’ or ‘glob’) is used in a
context where an identifier is allowed but where a string literal is
not allowed, then the token is understood to be an identifier instead
of a string literal.

If a keyword in double quotes (ex: “key” or “glob”) is used in a
context where it cannot be resolved to an identifier but where a
string literal is allowed, then the token is understood to be a string
literal instead of an identifier.
