for table
foo
banned:boolean
When try run 'insert into foo(banned) values(0)'
It returns
ERROR: column "banned" is of type boolean but expression is of type
integer
LINE 1: insert into foo(banned) values(0)
and I found a way to add the cast
insert into foo(banned) values(0::boolean)
but I have a big table which dump from mysqldump and covert by
mysql2pgsql. all of boolean relation values is 0 instead of '0' or
FALSE.
Is there any way to make pgsql implicit cast the integer to boolean?
If that is a one-time thing, why not create the table with banned as an integer
column and another boolean column (if your INSERTs are properly listing the
column names), then after the import update the boolean to the casted integer
value, drop the integer and rename the boolean?
Something like:
CREATE TABLE foo (banned integer, banned_b boolean);
-- run your inserts
update foo set banned_b =
case banned
when 0 then false
else true
end;
alter table foo drop column banned;
alter table foo rename column banned_b to banned;
