Hello everybody.
I''ve just converted an access database to postgres. The conversion
was ok, but when i'm trying to insert data on some tables with boolean
types from a Visual Basic application i receive an error. A sample:
table example, with firs field of integer, second of type text and
third of type boolean
the query: INSERT INTO EXAMPLE VALUES (1, 'text', 0)
When i used access this worked fine, in boolean types 0 is false and
1 is true, but in postgres (8.1 and 8.3 version) i receive the next error:
column "premarco" is of type boolean but _expression_ is of type integer
My question is, can i force postgres to accept integer values as
boolean without changin query to INSERT INTO EXAMPLE VALUES (1, 'text',
0::boolean). This is a problem because if I have to do this i will have
to test about one hundred queryes
Thank you very much
Two options:
1) Change the column in Postgres to an integer type.
2) Change the assignment in pg_cast from explicit to implied for the
int4,bool cast. See for more details:
http://www.postgresql.org/docs/8.3/interactive/catalog-pg-cast.html
Thank you very much. I've choosen the second option, using this
query:
update pg_cast set castcontext='i' where castsource=23 and
casttarget=16
