Hello! I have a timestamp field with an index

how can I select the fields from a given date, but using the index?

If I do:

where
     ((cast (MyTimeStamp as date)) between :from_date and :to_date)

I guess that is better not to do the cast and pass the params with date
+ time.

I use Delphi and I don't know how to add the time to the date in order
to pass the parameter to the query...

I'm trying with (to get all records from Feb 2nd)

where
     (MyTimeStamp between '02-01-2012 00:00:00' and '02-01-2012 23:59:59')

it uses the index, but I don't get all the records

Thanks!!!!

hi,

using this to install firebird:

yum install firebird-classic.x86_64

it works in centos 6.2. now where is the ibase.h? i need that to compile some
other modules.

Thanks,

Wang

My mistake!... that seems to work OK... Now I just wonder if that is the *best*
way to do that... So far I see no problem, but just in case...

Float is a useless datatype, having only seven digits of decimal
precision.  You'll do better with double - with about 16 decimal
digits of precision.  Even that isn't enough for an accurate
representation of your number, which needs 21 digits.  I think the
closest you'll come is decimal [19,19]

Hi, I'm trying to use fbtracemgr, but I get nothing coming out after I've run a
query.  Here is my config file:
<database mydb.fdb>
       enabled true
log_transactions true
log_trigger_start true
log_trigger_end true
print_perf true
prin_plan true
log_procedure_start true
log_procedure_finish true
</database>

and here is my command:
fbtracemgr.exe -SE localhost:service_mgr -USER SYS DBA -PASS masterkey -NAME
"my_trace" -START -C "my_trace.cfg" > my_trace.log

Is there anything I'm doing wrong?  Have I left anything out?

Hallo,

SQL databases are always in for a surprise about performance of simple
statements.

I have a table with the column 'ID' as BIGINT unique primary key.

The table has about 4000000 entries, the ID counts up without gaps.

A simple

	 select max(ID) from T

takes about 14 seconds complete.

Execution plan:

	 PLAN (T NATURAL)

So Firebird seems to do plan a full table scan. (Hallo, anyone at home?
I have an unique index on that column ;-) )

Some databases can do so much better here: The same statement on a 100%
identical Derby database completes immediately, as does on an Oracle 10g XE.

Do I miss something ? Any suggestions ?

Best regards

As far as I know, you need a DESC index for MAX queries.

Do you get an error when starting the trace session or do you get a line
that the trace session has been started successfully?

With what connect string does your client appliation connect?

- Have you run gfix to check for corruption?
- What's happening when you fool the optimizer to not use the index on
audit_id (I guess audit_id is the primary key column) by adding +0 to
the field in the where clause.

You need an DESCENDING index on the primary key column to speed up a MAX
operation, but I wonder what you are doing with that value then?
Hopefully not incrementing the value by 1 and use that as primary key
value then?

Thanks for the suggestions.
For some strange reason all seems to be fine now. DB Workbench finds the
record
(and looks normal data) and works fine via ODBC as well. No idea what went
on there.

thanks Ann,
You're right, the best option seems to be decimal (18,18).
(19,19) doesn't work :
SQL error code = -842. Precision must be from 1 to 18

Particularly true when you switch between record locking and MVCC.

Yes, there is someone at home.  The problem is that in an MVCC system,
the MAX value in the index may belong to a record that's not
appropriate for your transaction.  Firebird indexes cannot be
traversed backward and can change between reads.

> Some databases can do so much better here: The same statement on a 100%

Right.  And neither of those has index entries for transactions with
different snapshots of the database.

If you actually need to find the MAX often, create a descending index.
  If you're using the MAX to figure out what the next id should be, use
generators (aka sequences).

Good luck,

what is the best way to do a join to a "top 1 row" select of second
table? For example CAR and CAR_IMAGES to display just one image.
I wrote following select, this works. However I think there must be a
clever way to use "ROWS 1" instead of "min() and group by".

SELECT
CMRK.CAR_MARK_NAME,
CMDL.CAR_MODEL_NAME,
fltp.fuel_type_name,
C.MANUF_YEAR,
C.KILOMETER,
C.PRICE,
C.CURRENCY_CODE,
c.CAR_INFO,
clr.COLOR_NAME,
p.name,
p.phone,
p.email,
ci.car_image_id

P.S. I would suggest that the "headshot" image for a given car be stored as a
field in the Car table, to save yourself for the extra select.

Hello:

After using Firebird (2.5 SS) exclusively in a desktop application
environment, I've created an associated app that stores data at an
internet address.

I just finished the code to allow me via a remote site to backup and
immediately restore as a maintenance operation the database.

My plan was to back up to a temp file, then restore that to another temp
file, Disconnect, Shutdown the database with GFIX then FTP.rename the
original database to a filename with time stamp string and then
FTP.rename the temp file to the original database name.

My mistake is that GFIX shutdown would allow this to happen.

How do you allow a rename of the database in an FTP operation? Or is
there a better way of doing what I am trying to do? I am hesitant to do
a restore directly over the original database, but maybe someone can
advise me on that?

Thank you,

Chuck Belanger

This is how I ended up doing it:

Initially I have been using IBOServices to do my local hard drive FDB
backups.

My routine that seems to work now:
1. Check for connected users using a query of MON$Attachments, other
than connection used in the utility app.
2. Disconnect the app I'm using.
3. GFIX shut force 0
4. Do a IBOServices backup with verbose, mainly to make sure the backup
file actually exists on the server when the code progresses to the
restore line. This creates a file with a time string embedded in its name.

5. IBOServices RESTORE simply does not work to write over the existing
FDB, so I use a ShellAPI call to GBAK using the service mgr -r o switch.
Works fine.

The backup gives me some confidence that I have a good file if something
should go wrong when restoring directly to the DB.

Afterward, I re-open the queries for the program, after putting the DB
online and re-connecting.

Is there something I'm missing for doing this DB backup/restore maintenance?

Thank you,

Chuck Belanger

Maybe it is me, but I don't see any clear problem description and I am

Hello Thomas,

sorry for the late reply. I got distracted by other things :(

Now that some time has passed, I'm having trouble to remember the last status on
this issue, unfortunately.
Trying to restore it in my memory, but the result is not the same, I believe. So
I'm more or less starting from zero again.

I've tried to divide the post into separate parts to keep some kind of
structure...


========
Part 1:
========
To my question

>> creation of a ODBC connection to an embedded server works with SYSDBA only,
>> is that correct? I was not able to create one with another user.

you replied with

> No. You should be able to connect with a different user as well. It
> might fail for some reason because the specified user doesn't have
> sufficient privileges on database objects ...

I've tried to set it up again and apparently something was wrong with my
previous attempts. Now I can connect with every combination:
- SYSDBA + (correct / wrong password)
- any other users with random passwords
- and also without any users / passwords at all

so in the end it comes down to what you said:

>> Embedded works that way: The provided user/password combination isn't
>> checked against the security database, but SQL privileges are checked
>> for the provided user when it comes to accessing tables, views etc ...

I think I get it now, but one question regarding this remains:
If I'm not totaly wrong, there is no real user management for the embedded
solution. How can the provided user / his privileges be checked then?

Is it enough to say

CREATE ROLE READACCESS;
GRANT READACCESS TO SOMEUSERNAME;

although the user "SOMEUSERNAME" doesn't really exist?


========
Part 2:
========
When I said "Now I can connect with every combination" above, I meant that the
test connection works from the ODBC interface. When I try to access the
"database" in Excel, I'm getting the error message "bad parameters on attach or
create database CHARACTER SET ISO8859_1 is not defined". My database is created
with this character set and that's also the character set of the ODBC entry.

There are several topics on several forums regarding this issue, but most are
pretty old and somehow there are tons of attempts to fix it and as far as I've
seen no proper solution. Files are being copied back and forth, path variables
etc...

Can't believe it's that complicated and weird...

In my case the end user has our application installed. It uses a firebird
database. It can be installed as an embedded solution or as a client-server
solution. At this point ODBC isn't relevant yet.
It can be set up additionaly, in case the end user needs some additional data
for exports etc.

How has it to be set up correctly, so that he can still use the "normal"
application and also ODBC?


========
Part 3:
========
Assuming everything above is sorted and set up properly, so that also access via
excel works. The roles become relevant. As far as I see, the user, which was
used for creation of the database (the owner) automatically has full access /
all privileges.

If I add another user to security.fdb - let's call him "ODBCREADUSER", create a
role "ODBCREADROLE" and grant this role to this user, it is not enough. I still
need to grant the "select"-rights for desired tables to this role (GRANT SELECT
ON CUSTOMERS TO ODBCREADROLE; etc.) - so far correct?

If at some point I need to apply some changes to the structure of my database,
i.e. add some new tables, the owner has full access / all privileges on the new
tables automatically, but for the additional user "ODBCREADUSER" or better to
say for the role used by that user, i.e. "ODBCREADROLE", it doesn't happen
automatically, so I need to call "GRANT SELECT ON NEW_TABLE1 TO ODBCREADROLE;"
explicitely for all new tables everytime I change the structure, right?

What if only some new fields have been added? Do I have to do anything regarding
the roles in such a case?


Kind regards,
Patrick

Hi Mark,

I thought that

www.sendspace.com/

and

www.vworker.com

would be known enough, one as a file hosting site, the other as a freelancers'
opportunities site.

Explanations are a bit long (readme.txt) and useless without the test database
(polimi.err), so I compressed both into a ZIP file.

A closer look will tell that is actually an innocent ZIP file what I invite to
download.

Is there a better way I can save a file to download and overcome any paranoia ?

As a further test, I uploaded the ZIP file as a google shared doc, too

Thank you

Quick look at readme (note: haven't read it, or tried it out).

In your first example: perhaps you need to do a commit after your delete
statement and before calling the stored procedure, e.g. something like
(air code, not tested):

delete from a_job
where d_ini='2012-03-05';
commit;

select result
from DUPLICATEJOB (
'a1f61856-1c13-11e1-addd-00219bfd1931',
'a7df0588-4388-11e1-addd-00219bfd1931',
'2012-03-05',
null);

Hi Reiner,

> perhaps you need to do a commit after your delete

not so ... and not so easy :)

I tried all the easy things :)

Thank you

Peppe

334 coders went thru my request of paid help in vworker.com until now.

None took it... :(

Without providing the mandatory UDFs, one can't execute your stored
procedures.

As you are using SPs in other SPs, possibly you see some older PSQL code
executing when you are developing the stored procedures? Or perhaps
there is something wrong with your logic. ;-)

somebody put me into the right track.

My SQL client seems to be too old.

When using IB_SQL created with IBObjects v. 4.8.7 my SP returns -60.

I downloaded the last version of IB_SQL (which uses IBO v. 5.0.2) and the SP
correctly returns 0.

I have the solution of my problem now.

This costed me several hours of work and frustration :(

Thank you

Peppe

Good to hear that you solved it. I do want to advise you in the future
to take the time to post your actual question or at least a more
substantial introduction to your problem directly to this mailing-list
instead of making us jump through hoops like going to a different site
(and even there the actual question still isn't explained). And then
requiring us to download all kinds of files to even discover what your
actual problem is.

You are the one with the problem, so it is up to you to make it easy to
get actual help.

What is a good and recommended way to dynamically build a query inside
stored procedure?

For example a typical web portal search engine. user can select one or
many input parameters for a search.
For example car_model, fuel_type, color, gearbox_type etc. then into
select statement where part should be put only those what have value.

I started to look at first at "EXECUTE STATEMENT". but then in
documentation found sentence "Operations will be slow because the
embedded statement has to be prepared every time it is executed.".

then thought probably there is a better way? how to do it?

Hello,

Is it possible to change the charset of all columns and also the default
database charset to NONE? i just want to change the charset definition, not the
data himself. This because i want that it is the client to be responsible to
know in with charset he store the data.

i know their is some tools to make a backup of the database in SQL script and
after we can edit this script (like in mysql), but our database is too big for
such script (+300 GO) and the backup / restore will take weeks :(
