Here are more details about error checking and return values from multi_query(). Testing shows that there are some mysqli properties to check for each result: affected_rows errno error insert_id warning_count If error or errno are not empty then the remaining queries did not return anything, even though error and errno will appear to be empty if processing further results is continued. Also note that get_warnings() will not work with multi_query(). It can only be used after looping through all results, and it will only get the warnings for the last one of the queries and not for any others. Tropical Ecology Kricher Pdf Printer. If you need to see or log query warning strings then you must not use multi_query(), because you can only see the warning_count value. Note that you need to use this function to call Stored Procedures! If you experience 'lost connection to MySQL server' errors with your Stored Procedure calls then you did not fetch the 'OK' (or 'ERR') message, which is a second result-set from a Stored Procedure call.

You have to fetch that result to have no problems with subsequent queries. Bad example, will FAIL now and then on subsequent calls: sqlLink, $sQuery )) $this ->queryError (); $this ->sqlResult = mysqli_store_result ( $this ->sqlLink );?>Working example: sqlLink, $sQuery )) $this ->queryError (); $this ->sqlResult = mysqli_store_result ( $this ->sqlLink ); if( mysqli_more_results ( $this ->sqlLink )) while( mysqli_next_result ( $this ->sqlLink ));?>Of course you can do more with the multiple results then just throwing them away, but for most this will suffice. You could for example make an 'sp' function which will kill the 2nd 'ok' result. This nasty 'OK'-message made me spend hours trying to figure out why MySQL server was logging warnings with 'bad packets from client' and PHP mysql_error() with 'Connection lost'.

If you want to create a table with triggers, procedures or functions in one multiline query you may stuck with a error - #1064 - You have an error in your SQL syntax; xxx corresponds to your MySQL server version for the right syntax to use near 'DELIMITER' at line 1 The solution is very simple - don't use DELIMITER keyword at all! So, instead of: DELIMITER CREATE TRIGGER $dbName.$iname BEFORE INSERT ON $table FOR EACH ROW BEGIN EOT DELIMITER; just use: CREATE TRIGGER $dbName.$iname BEFORE INSERT ON $table FOR EACH ROW BEGIN EOT; For more information read answers at StackOverflow for question #5311141. If you don't iterate through all results you get 'server has gone away' error message. To resolve this, in php 5.2 it is enough to use next_result ());?>to drop unwanted results, but in php 5.3 using only this throws mysqli::next_result(): There is no next result set. Please, call mysqli_more_results()/mysqli::more_results() to check whether to call this function/method so it should be replaced with more_results () && $mysqli ->next_result ());?>I also tried but failed: more_results ()) $mysqli ->next_result (); // also throws error in some cases if ( $mysqli ->more_results ()) while ( $mysqli ->next_result ());?.
