ID: 28264 User updated by: csaba at alum dot mit dot edu Reported By: csaba at alum dot mit dot edu -Status: Closed +Status: Open -Bug Type: SQLite related +Bug Type: Documentation problem Operating System: Win 2K Pro PHP Version: 5CVS-2004-05-03 (dev) New Comment: It's unclear to me from the earlier comments that fixed means there is another function which mostly does what this one is documented as supposed to be doing (and today's earlier rejoinder is the the first mention of sqlite_exec). Nevertheless, I had tested with sqlite_exec before submitting the report earlier today, and yes, it does do multiple queries. To me, fixed includes the documentation agreeing with observed behaviour. As I noted in the original report, the documentation for sqlite_query says that SQLite will execute multiple queries. If the code isn't going to change, perhaps the documentation should. Therefore, I have reclassified the Category as 'Documentation problem'. Previous Comments: ------------------------------------------------------------------------ [2005-04-05 01:19:18] sniper@php.net It was fixed: You need to use sqlite_exec() instead of sqlite_query() (took about 2 minutes for me to figure out and I don't use SQLite at all..) ------------------------------------------------------------------------ [2005-04-04 22:00:25] csaba at alum dot mit dot edu This is still behaving in the same way as originally described (just tested on PHP 5.0.4-dev 11-Mar-2005). Here is slightly nicer code to show the problem: <?php $db = sqlite_open(':memory:', 0666, $sqliteerror); $tbl = "delme"; $multiQuery = "CREATE TABLE $tbl " . "(foo INTEGER PRIMARY KEY, bar TEXT);" . "INSERT INTO $tbl VALUES (null, 'Hi Mom');"; $dbRes = sqlite_query ($db, $multiQuery); $creationTest = "PRAGMA table_info('$tbl');"; $insertTest = "SELECT * FROM $tbl;"; $acT = sqlite_array_query ($db, $creationTest, SQLITE_ASSOC); print "<br><br>Table was created:<br>"; var_dump ($acT); $aiT = sqlite_array_query ($db, $insertTest, SQLITE_ASSOC); print "<br><br>"; if ($aiT) {print "with rows:<br>"; var_dump ($aiT); } else print "but nothing was inserted"; ?> Csaba ------------------------------------------------------------------------ [2004-07-10 15:14:35] wez@php.net This bug has been fixed in CVS. Snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. Thank you for the report, and for helping us make PHP better. "Fixed" in CVS. http://cvs.php.net/diff.php/pecl/sqlite/sqlite.c?r1=1.62.2.21&r2=1.62.2.22&ty=u ------------------------------------------------------------------------ [2004-05-27 00:15:40] saleh at sfsj dot net I also want to add that even if you try to use transactions to execute multiple queries.. I tried to use BEGIN; and BEGIN TRANSACTION; but both of them will not work and nothing will happen.. ------------------------------------------------------------------------ [2004-05-03 22:41:50] csaba at alum dot mit dot edu Description: ------------ The sqlite_query page in a prominent box declares that SQLite will execute multiple queries separated by semicolons, but this seems not to be the case according to the test below. While I posted a workaround for this, it is not very efficient because you have to send each query separately. I have tested the command line version of SQLite (2.8.13) and it does accept multiple queries separated by semicolons. Also, if dealing with this problem, I'd like to suggest that if the final query is a SELECT or other statement which produces some result normally destined for the user, that it be returned to the caller that way. The documentation makes it seems like maybe it will and maybe it won't, saying it's undefined. In particular, it would be helpful if SELECT and PRAGMA returned their results. If you indulge me on that, please extend the functionality to sqlite_array_query. Thanks, Csaba Gabor Reproduce code: --------------- $db = sqlite_open(':memory:', 0666, $sqliteerror); $tbl = "delme"; $multiQuery = "CREATE TABLE $tbl (foo INTEGER PRIMARY KEY, bar TEXT);" . "INSERT INTO $tbl VALUES (null, 'Hi Mom');"; $dbRes = sqlite_query ($db, $multiQuery); $creationTest = "PRAGMA table_info('$tbl');"; $insertTest = "SELECT * FROM $tbl;"; $acT = sqlite_array_query ($db, $creationTest, SQLITE_ASSOC); var_dump ($acT); print "<br><br>Table was created,<br>"; $aiT = sqlite_array_query ($db, $insertTest, SQLITE_ASSOC); var_dump ($aiT); print "<br>but nothing was inserted"; Expected result: ---------------- I expect to that the SQL INSERT statement was carried out Actual result: -------------- However, SQL statements after the first ';' seem to be ignored. Thus, the second var_dump only gets an empty array. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28264&edit=1
