MySQL is "smart" enough to increment its auto_increment value when you import data MySQL has no built in method for doing db size limits MySQL

Benefits (1) Able to handle large databases that can be accessed over the Web. Flexible and secure password system to protect your data - powerful security system Fast, reliable, easy to use, and affordable!

MySQL Example Connect to MySQL. Send a query. Print a table heading. Print table rows until end of the table has been reached.

MySQL Example <?php $conn = mysql_connect ( $host , $user , $password ); mysql_select_db ( $dbname ); $res = mysql_query ( "SELECT * FROM users" , $conn ); $header_printed = false ; print "<TABLE>\n" ; do { $data = mysql_fetch_array ( $res , MYSQL_ASSOC ); // Retrieve the next row of data. if ( ! is_array ( $data ) ) { break; }

MySQL Example ( continue ) if ( ! $header_printed ) { print " <TR>" ; reset ( $data ); while (list( $name , $value ) = each ( $data )) { print " <TH>$name</TH> \n " } print " </TR>\n" ; $header_printed = true ; } print " <TR>\n" ; print " <TD>" ; print implode ( "</TD>\n <TD>" , $data ); print " </TR>\n" ; } while ( $data ); print "</TABLE>\n" ; ?>
