Answer 2

this may be useful to you

SELECT COLUMN_NAME from information_schema.COLUMNS where TABLE_NAME='table' AND TABLE_SCHEMA='database_name'

information_schema is database containing meta data about all databases so when ever you want this kind of data you simply fire query on it

Answer 3

Try this:

SELECT GROUP_CONCAT(COLUMN_NAME) INTO @s 
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA = 'database_name' AND TABLE_NAME = 'tableName' AND 
      COLUMN_NAME LIKE '1%';

SET @sql = CONCAT('SELECT ', @s, ' FROM tableName');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
