c# - When i select from sqlite column of type 'int' I can cast to .net int but when I select from 'integer' column I cannot -

-

i'm using system.data.sqlite, selecting sqlite database table column has type 'integer', , when this: 

int x = (int)reader["mycolumn"];

it fails. problem not value null; column not nullable. if change data type of column 'int' works fine. values in column '2', '3', '4', etc.; nothing big.

anyone know if expected behaviour?

as other answerer mentioned, sqlite integer stored in 1, 2, 3, 4, 6, or 8 bytes. however, won't overflow or out of range exceptions.

in context, (int) cast, not conversion. if reader[] didn't return object of type integer, if it's returning different numeric type, cast exception, regardless of value contains.

based on range of valid values sqlite integer, i'd guess it's returning value 64-bit integer, long. verify, try this:

object x = reader["mycolumn"]; debug.writeline(x.gettype().name);

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
