How to reuse a table in MySQL Workbench?

Question

I read those solutions to the similar questions, but it did not seem to work in my case, I tried:

WITH tmp AS
( (things below is just an **example** to show that it will return a table)
SELECT 
*clounmname* FROM *tablename*
WHERE *XXXX*
)
SELECT *columnname* FROM tmp;

But my mysql workbench says the WITH at the very beginning is misused.. I also tried to add a ; before WITH, but it still does not work..

So I tried:

SELECT *columnname* FROM 
( (things below is just an **example** to show that it will return a table)
SELECT 
*clounmname* FROM *tablename*
WHERE *XXXX*
);

It runs with no error, but returns nothing.. So I don't know what to do, is there something wrong with mysql workbench?

(Version number of my Mysql worbench is 6.2 for Ubuntu 14.04) (The query above is just an example, I know AND and other stuffs.)

I even tried:

CREATE TABLE temp
SELECT *columnname* FROM 
( (things below is just an **example** to show that it will return a table)
SELECT 
*clounmname* FROM *tablename*
WHERE *XXXX*
);
SELECT *columnname* FROM temp;

But nothing returns without any error

Answer 1

MySQL does not support the WITH keyword at this time. Common Table Expressions are not available in MySQL yet.

The solution is to use a temporary or derived table or an inline view.

Answer 2

The query you are using is known as Common table Expression (CTE) . As of now, there is no support for CTE exist in MySQL . Alternative solution is to use either Temporary table or inline view .

So your posted CTE query can be modified with inline view as below. Where the result set returned from inner query will be treated as a temporary result set/view.

select * from
( 
SELECT *clounmname* 
FROM *tablename*
WHERE *XXXX*
) tab

If the result of the inner query will be used more than once then consider pulling that in a temporary table and then use that temporary table like below

create temporary table mytab (*clounmname* datatype);

insert into mytab
SELECT *clounmname* 
FROM *tablename*
WHERE *XXXX*;

select * from mytab;

Make sure that the datatype of the column in temporary table and datatype of the column in select list are same.
