Re: RV: no updateable recordset

Hi,

I'm trying to access to a postgreSQL database via ODBC. I'm able to read
the data without any problem from VB on windows, but I can't update or
insert any record.

I have NOT checked the 'read only' option of the driver.

I'm using Postgres 7.1.2 on a SuSE 6.3 Linux, and the 7.01.0005 driver. But
I had the problem previously (with version 7.0.2 and an older version of the
driver).

I can insert or update a record from 'psql' or via the unixODBC driver
installed on the same machine.

There's another extrange thing, I'm not able to modify any record, but I
can do a drop table via odbc (so the table is not read only). I'm using the
visual basic sample VisData to do the test. I've read something about a
msysconf file or table, in the logs I see the following:
>> Relation 'msysconf' does not exist'

>>conn=152710432,
SQLDriverConnect(out)='DSN=test;DATABASE=test;SERVER=server;
>>PORT=5432;UID=postgres;PWD=XXXX;READONLY=0;PROTOCOL=6.4;FAKEOIDINDEX=0;
>>SHOWOIDCOLUMN=0;ROWVERSIONING=0;SHOWSYSTEMTABLES=0;CONNSETTINGS='
>>conn=152710432,query='BEGIN'
>>conn=152710432, query='declare SQL_CUR095D0040 cursor for SELECT Config,
nValue FROM MSysConf'
>>ERROR from backend during send_query: 'ERROR: Relation 'msysconf' does
not exist'
>>conn=152710432, query='ABORT'
>>STATEMENT ERROR: func=SC_execute, desc='', errnum=-1, errmsg='Error while
executing the query (non-fatal)'

Does this mean that my databases should contain any tables to allow odbc
(write)connections? Can anybody help me?

Thanks in advance,

Manuel Martínez Valls

1. MS JET database engine reads some ODBC settings from MSysConf table:
CREATE TABLE "msysconf" (
"config" int2 NOT NULL,
"chvalue" character varying,
"nvalue" int4,
"comments" character varying);
REVOKE ALL on "msysconf" from PUBLIC;
GRANT SELECT on "msysconf" to GROUP "odbcusers";
All ODBC users must have permission to use the SELECT statement on this
table. For correct settings look at DAO reference.
2. You need unique index to update table. Look around Recognize Unique
Indexes or Fake Index in PostgreSQL ODBC FAQ.

Hi again,

I've followed your advice and I've created this table, after that reading
the PostgreSQL ODBC FAQ I've realized that they recommend to install the
pgAdmin utility, so that's what I've done.

Now I have created the msysconf table as you told me, I've the following
values:

config=101, nvalue=1, comments='Allow local storage of passwords in
attachments'
config=102, nvalue=10, comments='Background population delay'
config=103, nvalue=100, comments='Background population size'

Now, I can't see any error on the logs, but I still having the same
no-uptdateable recordsets.

Can you told me which are the magic values?

Thanks for your help,

Manuel Martínez Valls

Sorry, I've already solved the problem. The solution is just to create the
MSysConf table but... I made a mistake, I was using the 'snapshot' option on
visdata and the data were obviously 'Not Updateable'.

Thanks for your help,
