folks! this first experience big scripts in php cli , i'm facing 'not found' error when using sqlsrv_connect function in script. running script in browser okay, connects fine, queries goes fine could; when in cli, friend, shows fatal error: call undefined function sqlsrv_connect() what be, dark magic or newbie developer? this how use function: $_dbip = '127.0.0.1'; $_dbnome = $nome_bd; $_dbuid = 'sa'; $_dbpwd = 'very_strong_secret_pwd'; $conn = sqlsrv_connect($_dbip, array('database' => $_dbnome, 'uid' => $_dbuid, 'pwd' => $_dbpwd)) or die( print_r( sqlsrv_errors(), true)); thanks in advance! there 2 php.ini files , 1 cli , 1 web browser. you need make sure extension enable on both. you should use pdo if possible, because better extension , supports sql server .

if define range in ada being 1 .. 1000, there defined behavior ada spec if increment past 1000? for example: type index range 1..1000; idx : index := 1; procedure increment begin idx := idx + 1; end what should expect happen once call increment idx = 1000? wraps around (idx = 1) out of range exception undefined behavior something else? your program fail constraint_error . however, not because try set idx 1001. rather initial value of 0 not within predefined range either. thankfully, compiler warn @ compile time fact. if had set idx permitted value , incremented beyond upper limit in way compiler cannot statically detect, again constraint_error raised (but there won't hint @ compile time). error technically exception can handle other exception in language. note: intentionally linked ancient ada '83 specs above show behavior has been part of language since beginning of time.

how possible files can contain null bytes in operating systems written in language null-terminating strings (namely, c)? for example, if run shell code: $ printf "hello\00, world!" > test.txt $ xxd test.txt 0000000: 4865 6c6c 6f00 2c20 576f 726c 6421 hello., world! i see null byte in test.txt (at least in os x). if c uses null-terminating strings, , os x written in c, how come file isn't terminated @ null byte, resulting in file containing hello instead of hello\00, world! ? there fundamental difference between files , strings? null-terminated strings c construct used determine end of sequence of characters intended used string. string manipulation functions such strcmp , strcpy , strchr , , others use construct perform duties. but can still read , write binary data contains null bytes within program , files. can't treat them strings. here's example of how works: #include <stdio.h> #include <stdlib.h> int main() {...

i have 2 tables: users (userid,student_no,name) , regd (semester,student_no) . users contain 7,000 records , regd contains 20,000 records. there entries in regd not in users . how quickly select entries in users have entries in regd semester = '2012-2'? tried this: select * `regd` , users semester = '2012-2' , users.student_no = regd.student_no but taking forever load queries if have tiny database. every 6 months, 10,000 entries added regd , 2,500 entries added users each year. add indexes on join columns: create index idx_regd_student_no on regd(student_no); and create index idx_users_student_no on users(student_no); also, if tables don't have pk, add one. in case of regd, can use pk = (semester, student_no) . as other comments say, 22k records not big, can assume without decent index. hope helps.
