php - Searching a HashByte column in MSSQL -


i'm trying search mssql table contains user data. 2 columns interested in username, , password. password column binary(20) datatype , contains data generated by

   hashbytes('sha1','password')

this call i'm making, without success. missing?

$select_user=sqlsrv_prepare($connection,"     select          id, username              dbo.users              username=? , password=hashbytes('sha1',?)",     array(&$username, &$password));

there nothing in post indicate doing prevent query working.

create table t (   usr varchar(100),   pwd binary(20)   );  insert t    (usr, pwd)   values    ('john', hashbytes('sha1', 'john-pwd'))  insert t    (usr, pwd)   values    ('jane', hashbytes('sha1', 'jane-pwd'))

and here sample query:

declare @pwd varchar(100) declare @usr varchar(100)  set @usr = 'john' set @pwd = 'john-pwd'  -- search john's record username & password select *   t  usr = @usr    , pwd = hashbytes('sha1', @pwd)

here sql fiddle link shows working sample: http://sqlfiddle.com/#!6/45766/2/0

usr   | pwd ------+---------------------------------------- john  | kwrra4hnlawscg4rjmry/9k43sm=

you cache hashed password query besides query should work fine.
