Обсуждение: DROP TABLE Appears to Fail

   I cannot recall issuing a DROP TABLE command from psql that did not work,
but seem to have this as a new experience.

   When I look at the database table list with '\d' I see

public | station_type                              | table    | rshepard
public | station_type_statype_seq                  | sequence | rshepard

and I want to drop and recreate these with a typo fixed. But, the drop
commands do not appear to work:

# drop table station_type

# \d

  public | station_type                              | table    | rshepard
  public | station_type_statype_seq                  | sequence | rshepard

   I fail to see what I'm doing incorrectly and would appreciate a clue stick
to set me on the proper path.

TIA,

Rich

Hi Rich,

it might be sufficient to add a semicolon to your drop statement:

# drop table station_type;

Andy,

   Actually, that's not true. On a whim I tried that and psql complained
about a syntax error at the initial 'd'.

Rick,

   See my answer to Andy: that's incorrect syntax and psql complains.

   But there is no continuation command just 'drop table <tablename>'.

Thanks,

Rich

specifically note the prompt.   the -# means you're in the middle of a
command.   =# means its ready for a new command.


as another example...

    pierce=# create table foo (id integer);
    CREATE TABLE
    pierce=# drop
    pierce-# table
    pierce-# foo
    pierce-# ;
    DROP TABLE
    pierce=#

   Ah, so! I didn't see this.

Thank you very much,
