Re: JBuilder 4 QDS problem - Mailing list pgsql-jdbc

This sort of has nothing to do with the jdbc driver the relevant error
message is:

Unable to identify an operator '=' for types 'numeric' and 'double
precision'

This is due to the backend not having an equals operator between your
two types

Subject: [JDBC] JBuilder 4 QDS problem


Hi,

Anyone using the Query Dataset that JBuilder 4.0 provided? I am using
PostgreSQL 7.2 with the latest JDBC driver, I defined a table with some
NUMERIC fields, e.g. NUMERIC(12,4). When I use the qds to get the data
from database, it has no problem. But when I want to save the data using
the qds, it cannot run with success. The qds will detect a wrong field
type for the numeric field and save fail. The program is working on DB2
with related JDBC driver. Anyone can help?

The exception:
com.borland.dx.sql.dataset.ResolutionException: An error occurred

(2002-02-03 12:01:58,310)
