I wanted to <a href="http://davidwalsh.name/backup-mysql-database-php" rel="nofollow noreferrer">backup my database with PHP</a>. I tested the linked script but it was never ending, I tried to prepend the <code>repair $table</code> before the query but it didn't help. So I figured out if I just skip two tables (you can see in the code) then it works fine: <pre><code><? error_reporting(E_ALL); ini_set('error_reporting',1); require('../basedatos.php'); echo 'included '; /* backup the db OR just a table */ function backup_tables($host,$user,$pass,$name,$tables = '*') { echo '1 '; //get all of the tables if($tables == '*') { $tables = array(); $result = mysql_query('SHOW TABLES') or die(msyql_error()); while($row = mysql_fetch_row($result)) { $tables[] = $row[0]; } } else { $tables = is_array($tables) ? $tables : explode(',',$tables); } echo '2 '; //cycle through foreach($tables as $table) { if($table == 'etiquetas' || $table == 'links') continue; $repair = mysql_query("REPAIR table $table") or die(mysql_error()); echo '3- '.$table.' '; $result = mysql_query('SELECT * FROM '.$table) or die(msyql_error()); $num_fields = mysql_num_fields($result); $return.= 'DROP TABLE '.$table.';'; $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table)) or die(msyql_error()); $return.= "\n\n".$row2[1].";\n\n"; for ($i = 0; $i < $num_fields; $i++) { while($row = mysql_fetch_row($result)) { $return.= 'INSERT INTO '.$table.' VALUES('; for($j=0; $j<$num_fields; $j++) { $row[$j] = addslashes($row[$j]); $row[$j] = ereg_replace("\n","\\n",$row[$j]); if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; } if ($j<($num_fields-1)) { $return.= ','; } } $return.= ");\n"; } } $return.="\n\n\n"; } echo '4 '; //save file $handle = fopen('db-backup-'.time().'-'.(md5(implode(',',$tables))).'.sql','w+'); fwrite($handle,$return); fclose($handle); } backup_tables('localhost','username','password','*'); ?> </code></pre> Is there any way to find the rows that are giving me a problem so I can edit/delete them? -PS- Also, I don't get any errors if I don't skip them (the script just never gets to the end, that's why I added some ugly logs.., any idea why? -EDIT- Also, if I try to export the database via, for example, sqlBuddy I also get errors: <img src="https://i.stack.imgur.com/F2cE4.png" alt="enter image description here">

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
