hvis du har ukendt antal page , kan du også PreparedStatement

SET @sql = NULL;
SELECT
  GROUP_CONCAT(DISTINCT
    CONCAT(
      'SUM(CASE WHEN `Page Visited` =''',
      `Page Visited`,
      ''' then 1 ELSE 0 end) AS ',
      CONCAT('`',`Page Visited`, ' Visits`')
    )
  ) INTO @sql
FROM TableName;

SET @sql = CONCAT('SELECT ID, Name, ', @sql, ' 
                   FROM tableName
                   GROUP BY ID, Name');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
