From: rphp at ryanjameson dot com Operating system: windows 2000 PHP version: 5.0.2 PHP Bug Type: ODBC related Bug description: odbc_fetch_row($rs,0) does not reset dataset.
Description: ------------ Since upgrading to 5.0 I've found that looping through a recordset ($rs) via odbc_fetch_row and then attempting to reuse the recordset by calling odbc_fetch_row($rs,0) seems to put me at the first record of the recordset versus giving me a "reset" recordset. The result is a subsequent odbc_fetch_row then puts me at the second item in the record set which is not how it behaved in previous versions. In previous versions calling odbc_fetch_row($rs,0) followed by odbc_fetch_row($rs) would leave you on the first row since the odbc_fetch_row($rs,0) had in effect reset the recordset. This ability is mentioned in the user contributed notes for this function. I have a rather large and intracate library partially built around the ability to "reset" recordsets. I have been unable to find another way to do this. Since installing PHP 5.0 all results that relied on this are missing the first row. :-\ Reproduce code: --------------- create a simple odbc record set ($rs) by selecting from any table then... odbc_fetch_row($rs); //moves the pointer //in past this would reset the pointer odbc_fetch_row($rs,0); $cnt = 0; while (fetch($rs)) $cnt++; echo "$cnt is one less than the actual result count because it started on the second row!"; Expected result: ---------------- I expect $cnt to equal the number of rows in the result set because odbc_fetch_row($rs,0) should reset the set, not move the pointer to the first row. Actual result: -------------- $cnt is one less than the result count. -- Edit bug report at http://bugs.php.net/?id=30876&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30876&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30876&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30876&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30876&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30876&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30876&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30876&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30876&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30876&r=support Expected behavior: http://bugs.php.net/fix.php?id=30876&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30876&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30876&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30876&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30876&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30876&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30876&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30876&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30876&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30876&r=mysqlcfg
