Hi Peter (and MySQL list),
On Wed, Jan 13, 2010 I (Ricardo Dias Marques) asked the following :
It would be convenient for me to get a list of those fields ordered by
field / column name.
... and on the same day, Peter Brawley peter.braw...@earthlink.net
kindly replied:
SELECT *
FROM
and the SHOW COLUMNS (or its synonym SHOW FIELDS) command:
MySQL :: MySQL 5.0 Reference Manual :: 12.3.1 DESCRIBE Syntax
http://dev.mysql.com/doc/refman/5.0/en/describe.html
MySQL :: MySQL 5.0 Reference Manual :: 12.5.5.5 SHOW COLUMNS Syntax
http://dev.mysql.com/doc/refman/5.0/en/show-columns.html
in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near 'ORDER BY Field' at line 1
So, I went to read the online documentation about the DESCRIBE command
and the SHOW COLUMNS (or its synonym SHOW FIELDS) command:
MySQL :: MySQL 5.0
create a
table containing 10 INT columns, the result of show columns from should show
the Type column length of 3 with a maximum data allocation for the 10 rows of
30 bytes, and not ~2MB, as is currently the case.
And even, in a worse case, MySQL Dev decided to give the length back
column. NOTE: The
result's. I.e. why give such an arbitrary number of bytes/length when no
ENUM's or SET's are even in the result. The point being, even if you create a
table containing 10 INT columns, the result of show columns from should show
the Type column length of 3 with a maximum data
Since a couple of recent stable versions back (and more recently, MySQL
5.0.22), MySQL has been returning the column length (C API) of the 'Type'
column of a show columns from.. statement as being 196605 (almost 192KB),
when this column only really contains data in the region of 10 bytes

Hi all,
I was wondering is it possible to use SHOW COLUMNS FROM tbl_name as a
subquery.
I tried something like this ( w/o success ):
SELECT * FROM tbl1 INNER JOIN (SHOW COLUMNS FROM tbl2) AS t2 WHERE t1.ID
=t2.field;
or
SELECT field FROM (show columns from Research.idefix);
