MySQL: Creating a new table with information from a query

In MySQL, I would like to create a new table with all the information in this query: select * into consultaa2 from SELECT

In MySQL, I would like to create a new table with all the information in this query:

select * into consultaa2 from SELECT
 CONCAT(    'UPDATE customers SET
 customers_default_address_id= ',    
 (SELECT a.address_book_id FROM
 address_book a where
 c.customers_id=a.customers_id order by
 address_book_id desc limit 1),    '
 WHERE customers_id = ', customers_id,
 ';') AS sql_statement FROM customers c
 where c.customers_id > 3894;

The query is too long for the brows开发者_运维百科er to show the concat and I need this to make this updates.


You can do it like this:

CREATE TABLE tablename SELECT * FROM othertable;

tablename is the name of the new table you want to create, SELECT * FROM othertable is the query that returns the data the table should be created from.


*Note that this method does not create a table (as per OP title). To do that see this answer.*


Inserting into a table with information from a query is of the format

INSERT INTO <TABLE-1> 
SELECT * FROM <TABLE-2>

In your case, it would be

insert into consultaa2 
SELECT CONCAT( 'UPDATE customers SET customers_default_address_id= ',
(SELECT a.address_book_id FROM address_book a where c.customers_id=a.customers_id order by address_book_id desc limit 1), ' WHERE customers_id = ', customers_id, ';') AS sql_statement FROM customers c where c.customers_id > 3894;

Just make sure the columns in the table you are inserting into and the columns returned from the select query match.


mysql create new table

Example from mysql commandline.

mysql> create table foo(id int, vorta text);
Query OK, 0 rows affected (0.02 sec)

Insert rows

mysql> insert into foo values(1, 'for the hoarde');
Query OK, 1 row affected (0.00 sec)

look what's in there

mysql> select * from foo;
+------+----------------+
| id   | vorta          |
+------+----------------+
|    1 | for the horde  |
+------+----------------+
1 row in set (0.00 sec)

Create a new table with information from a query

mysql> create table foo2 select * from foo;
Query OK, 1 row affected (0.01 sec)
Records: 1  Duplicates: 0  Warnings: 0

Check if the data moved

mysql> select * from foo2;
+------+----------------+
| id   | vorta          |
+------+----------------+
|    1 | for the horde  |
+------+----------------+
1 row in set (0.00 sec)
