Create a table with column names derived from row values of another table

Question

Suppose I have the following table with a single column:

Table_1

-----------
| nameCol |
-----------
| A       |
| A       |
| B       |
| C       |         


        

Answer 1

You could use a dynamic query:

SELECT
  CONCAT(
    'CREATE TABLE Table_2 (',
    GROUP_CONCAT(DISTINCT
      CONCAT(nameCol, ' VARCHAR(50)')
      SEPARATOR ','),
    ');')
FROM
  Table_1
INTO @sql;

PREPARE stmt FROM @sql;
EXECUTE stmt;
