Select only columns with null/empty values from the table

You can do it with dynamic SQL like this

DELIMITER $$
CREATE PROCEDURE sp_empty()
BEGIN
  SET @sql = NULL;

  SELECT GROUP_CONCAT(
           CONCAT('(SELECT GROUP_CONCAT(id) FROM Table1 WHERE `', 
                  column_name, '` IS NULL ',
                  CASE  
                    WHEN data_type IN('varchar', 'char') 
                      THEN CONCAT('OR `', column_name, '` = ''''')
                    WHEN data_type IN('date', 'datetime', 'time') 
                      THEN CONCAT('OR `', column_name, '` = 0')
                    ELSE ''
                  END, ')`', column_name, '`'))
     INTO @sql
    FROM INFORMATION_SCHEMA.COLUMNS
   WHERE table_schema = SCHEMA()
     AND table_name = 'table1'
     AND column_name NOT IN ('id')
   GROUP BY table_name;

  SET @sql = CONCAT('SELECT ', @sql);

  PREPARE stmt FROM @sql;
  EXECUTE stmt;
  DEALLOCATE PREPARE stmt;
END$$
DELIMITER ;

Note that it takes care of different data types of columns.

Sample usage:

CALL sp_empty();

Output:

| DATA1 | DATA2 | DATA3 |
|-------|-------|-------|
|     2 |   1,4 |     1 |

Here is SQLFiddle demo

SET @sql = NULL;

SELECT GROUP_CONCAT(
         CONCAT('(SELECT GROUP_CONCAT(id) FROM Table1 WHERE `', 
                column_name, '` IS NULL ',
                CASE  
                  WHEN data_type IN('varchar', 'char') 
                    THEN CONCAT('OR `', column_name, '` = ''''')
                  WHEN data_type IN('date', 'datetime', 'time') 
                    THEN CONCAT('OR `', column_name, '` = 0')
                  ELSE ''
                END, ')`', column_name, '`'))
   INTO @sql
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE table_schema = SCHEMA()
   AND table_name = 'table1'
   AND column_name NOT IN ('id')
 GROUP BY table_name;

SET @sql = CONCAT('SELECT ', @sql);

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

If for some reason you can't use a version with dynamic SQL, then as a last resort you can produce a query like this on your own including all of your columns

SELECT 
(
  SELECT GROUP_CONCAT(id) 
     FROM Table1 
    WHERE `data1` IS NULL 
       OR `data1` = ''
) `data1`,
(
  SELECT GROUP_CONCAT(id) 
    FROM Table1 
   WHERE `data2` IS NULL
) `data2`,
(
  SELECT GROUP_CONCAT(id) 
    FROM Table1 
   WHERE `data3` IS NULL 
      OR `data3` = 0
) `data3`
...

This would probably be a bad idea considering you have up to 20 data columns, but would something like this work?

SELECT * FROM
    (SELECT GROUP_CONCAT(id) data1 FROM foo WHERE data1 IS NULL OR data1 = '') AS f1,
    (SELECT GROUP_CONCAT(id) data2 FROM foo WHERE data2 IS NULL OR data2 = '') AS f2,
    (SELECT GROUP_CONCAT(id) data3 FROM foo WHERE data3 IS NULL OR data3 = '') AS f3
