android - how to query against array of integer -

-

i query:

select * table field1 in (1, 2 ,3);

the field1 integer type. field type string be:

select * table field1 in ('1', '2' ,'3');

but in android both use selectionars string[].

string[] filter = new string("1", "2", "3"); cursor altocursor = mcontentresolver.query(                 uri, projection,                 "field1 in (?,?,?)" +                 filter, null);

how different field type string, field1 type of string. query same, how know if "1" in string[] integer or string:

string[] filter = new string("1", "2", "3"); cursor altocursor = mcontentresolver.query(                 uri, projection,                 "field1 in (?,?,?)" +                 filter, null);

confused here, anyone's appreciated!

typically data type of column querying defined integer or string.

database engine not realize if passing string or integer. moment query passed sql engine through error if placing integer values in string column without quote.

  1. check column querying
  2. if string encode them quote
  3. if integer can pass values as comma separated values

to test if string integer can use if (x int)

but in case android smart enough put code them-self guess

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

python - PyCharm Type error Message -

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
