Hey guys,

 

I found this interesting…

 

 

test=# create table t ( c char);

CREATE TABLE

 

test =# \d t

         Table "public.t"

 Column |     Type     | Modifiers

--------+--------------+-----------

 c      | character(1) |

 

test =# alter table t drop column c;

ALTER TABLE

 

test =# \d t

     Table "public.t"

 Column | Type | Modifiers

--------+------+-----------

 

test =# select * from t;

 

--

(0 rows)

 

test =# create table t2 ();

CREATE TABLE

 

test =# select * from t2;

 

--

(0 rows)

 

 

I mean, we have a table with nothing on it.  Of course this maybe useful
if like to check if an object exists in pg_class for some reasons.  But
nah… we can have other workarounds for that.  Is this allowed in SQL?

 

 

Thanks,

 

 

herbert
