Re: [Info-Ingres] bad procedure screws good procedure

Works fine for me on the datallegro variant of both main and 9.1.1.
I can't think of any specific datallegro fixes that would address
whatever this problem is. So I'm guessing that it's fixed (by Ingres
Corp) in a more recent 9.1.1 than what you are testing.

Re: [Info-Ingres] Question on usermod command

I have tested patch P12814 for Solaris and Ingres 2.6. It has a fix for
bug 101117:
"Failures during usermod can lead to non-persistent objects being
dropped without warning."
Also look out for a pending fix for bugs 120485:
"If a usermod fails because of a lock timeout the temporary files (in
II_TEMPORARY) are removed."

Re: [Info-Ingres] get returned value of stored procedure in ingres

I'm not sure I properly understand your question, but maybe this is what
you want to know:
There are several ways to return values from Ingres 2006 database
procedures (DBPs). First off, there's the RETURN statement, which
allows you to return a single integer value. The second possibility is
to call the procedure and pass the arguments BYREF, and in the parameter

Re: [Info-Ingres] Question on usermod command

The 2.6 documentation was misleading. It was corrected in Ingres2006.
In 2.6 be sure to capture the output of the usermod command (I use tee) so,
after a fail condition, you can restart the rebuild at the correct point.
In case of any fails, dont run usermod a second time otherwise you risk
losing index definitions. It is a good idea to keep a backup copy of the

[Info-Ingres] Question on usermod command

2008-07-21T18:20:06Z

The Ingres 2.6 Command Reference Guide's description for the usermod command states "The usermod command modifies a database's user-defined tables to the most appropriate storage structure for accelerating query processing."
I had thought that usermod simply modified the tables to their defined storage structures which is what I recall seeing in the description for usermod in the Ingres 2006 Command Reference Guide.

Hello Naïm,
Please have a look to the function called "return" (see details in the
SQL Documentation).
Hope this help.

[Info-Ingres] jdbc caches prepared statements?

2008-07-21T12:41:01Z

Hi Everyone,

I have a jdbc application which maintanes a connection to a database.

Every morning, the application fires up and runs a set of queries using
this long standing connection.

To generate a set of reports the application runs the same sets of
queries, using a prepare statement, open cursor for statement, fetch

[Info-Ingres] get returned value of stored procedure in ingres

2008-07-18T07:59:39Z

I want to migrate some stored functions from oracle to ingres.
If i am not wrong, I must create a procedure in ingres which returns the
value that was returned by oracle function.
The problem is that I haven't found a way to get this value.
I wanted to know if it is possible to get this returned value in ingres and

How come I'm the one who has to pay $50 for mentioning a perfectly
reasonable new feature? That's got to be well into three figures
worth. In fact I think that's gotta be drinks all round. (Although I do
remember Bruce Lunsford daydreaming about something along those lines
years ago.)

Sounds about right to me!
In that case, it's a good thing I didn't ask for something like
combining the STAR and DBMS servers and removing the distinction between
local and distributed databases, so that we could register tables
directly into a normal database.

Whinge, whinge, whinge. Some people are just never satisfied.
I suppose you want something like "prepared statement was invalidated by
DDL".
I have a quarter here that says this one is going to turn out to be
bizarrely more complicated to fix than any sane person might imagine.
I haven't looked at the code at all, I'm just guessing wildly ...

[Info-Ingres] Dropping a table before the cursor read!

2008-07-18T14:54:03Z

Hi Everyone,

I love query auditing, it can really show exactly which query - or
sequence of queries - is producing errors!

And in this case we see this little beauty:
drop table a_table;
create table a_table(...sundry column definitions...);
prepare statement select count(*) from a_table;
drop table a_table; /* Whoops! */

Re: How much does a view remember?

2008-07-18T13:49:03Z

I note with interest that you can insert a longer value through the
view, so it is only the retrieval from the view that has a problem. I
then looked at the standard and it does indeed allow a string column
to be increased in size. It appears to me that it expects subsequent
operations on a view column based on a changed underlying column to

Could be an Opensource project there. Are you interested?
