Summary: 08.02.01: Incorrect size returned for adVarWChar and adVarChar fields after Paremeters.Refresh.
Initial Comment:
I'm using VB6 on a Windows XP machine with ODBC driver 08.02.01 and PostgreSQL 8.2beta1.
CREATE TABLE testtable
(
code integer NOT NULL,
testfield character varying(5000),
CONSTRAINT proschargemstrpk PRIMARY KEY (proschargecode)
)
When I use a Command object, set the CommandText, and perform a .Parameters.Refresh, the .Size of testfield's parameter
is254 instead of 5000 and setting the .Value of the parameter to anything longer than 254 characters results in an
error. This happens with both the Unicode and ANSI drivers.
The create table statement that pgAdmin III gives me is included at the top. If any additional information is needed,
Iwill provide it.

Unfortunately this problem is hard to solve.
Couldn't you change the defintion of the textfiled
from varchar(5000) to text ?

I did find a work-around for this by change MaxVarcharSize
to match the Max LongVarChar size, but I don't think the
parameter should say it's a VarChar(254) when it's a
LongVarChar(5000).
The "Text as LongVarChar" checkbox has been checked on the
DSN's property pages.

Sorry, the primary key should be "code"... I meant to
simplify the field names, but forgot to change the
constraint line.
