ODBC-client->Linux-server: datatype boolean not recognized?

Jelle Ruttenberg <ruttenberg@neroc.nl> — 1999-09-30T14:46:16Z

Hello all,

I posted the following also to pgsql-interfaces/general, but got no 
workable solution (yet).

The ODBC client-application I'm developping will be able to run on Mac 
and WIN/NT, uses booleans itself and has to be able to be a frontend for 
a range of SQL-databases.


Thanks,
Jelle

Hello all,

I'm trying to connect from a ODBC-client to PostgreSQL on a Linux-server. 
All is going well, except that the ODBC-client seems not to recognize the 
PostgreSQL boolean-datatype.

Is this really caused by PostgreSQL? If yes: is there a workaround, like 
altering the datatypename 'bool' in the proper places (pg_type?)? If no: 
then it is another problem and can somebody give a hint?

Thanks,
Jelle.


I tested and encountered it in the following testsituations:

Situation 1:
Client: Mac via OpenLink ODBC-Client
Server: Linux RH 6.0 via OpenLink Requestbroker
Result: it looks like PostgreSQL-boolean is converted to SQL_C_CHAR, the 
datatype itself is called 'bool'

Situation 2:
Client: NT with psqlODBC
Server: same Linux
Result: in MS-Query:
-  viewing the table-definitions, it comes with the message that it 
doesn't recognize datatype 'bool'
-  selecting values it looks like PostgreSQL-boolean is converted to a 
numeric

PostgreSQL: 6.5.1
