Re: column insert/alter got me stumped!

I think you want this:

update tablename set columname = 'value'
where column2 = 'value2';

guys,
just wanna change value of 1 existing column

# insert into tablename (columnname) values ('value');
...works

# select columnname from tablename where columnname='value';
...works

# insert into tablename (columnname) values ('value') select
columnname from tablename where columnname='value';
or
# insert into tablename (columnname) values ('value') where
columnname='value';
...combinations don't work

# alter table tablename alter column columnname set value='value';
...doesn't work either

embarrassingly simple? pgadmin III thinks so
