For exact numbers you have to use exact numeric types.
Double is float point type with all advantages and disadvantages.
Look here

Just for fun, try this:
1e20 + 1 + 1 - 1e20 + 1

Hi all,
customers asking for clustering solution.
I found this one:

Do somebody experience with that, any reason to do not used?

Hi,
we are using combination of bat and SQL.
In bat file we are generating SQL and vice versa.
Some example:
@SET sql=s1.sql
@ECHO SET TERM ^^; >%sql%
@ECHO EXECUTE BLOCK AS>>%sql%
@ECHO DECLARE VARIABLE s VARCHAR(1000);>>%sql%
@ECHO BEGIN>>%sql%
@ECHO s = 'CREATE USER %3 PASSWORD
Hi,
I test general impact of compression and I found that for FB 2.5 and FB3
is critical to take another DB page from cache.
Also any cache miss significantly reduce performance.
With current compression and if we have a number lest say 0x3337 stored
in three columns.
BIGINT it will be
Hi,
advantage of SmallInt vs INT vs BIGINT is data density (keep record
shortest as possible).
If you have one column, it is irrelevant, if you have ten columns, you
will see speed improvement.

Hi,
I never used embedded, but seems to be, that you using wrong dll name.
Try to read this topic:
https://www.codeproject.com/Articles/9445/Embedded-Firebird-Full-Featured-Embedded-Database
Yes, look here:
public static void CreateDatabase(string connectionString, int pageSize
= 4096, bool forcedWrites = true, bool overwrite = false)
{
CreateDatabaseImpl(connectionString, pageSize, forcedWrites, overwrite);
} As connection string you can use file name. Look for example here:

Hi,
Dimitri is right.
If you just prepare statement (ANYONE) server will return record
structure including names and data types.
Also, you task is not problem to solve without prepare.
Just at first iteration read the names and put to output before data.

Hi,
look at my example that I'm using for preparing two DB fou join into one
big.
My be it will help you.
-- Prepare data table for replication
-- Ensure that data in both databases are unique
-- No overlap during replication will occur
CREATE OR ALTER PROCEDURE Repl$SynchronizeDataTable(
We have another tables that contain definition of each relation and each
field.
Data for this tables are automatically generated from case tool like this:
EXECUTE BLOCK AS BEGIN
--definition fields for entity: USERFUNCTIONS

Hi Roland,
in some cases we did this to log all transaction starts commits (see
script below).
Set GenMonTransactions to value less 1 will activate log function.
You can simply to change to log transaction commits or rollbacks as well.
And in application you can easy log transaction id
Hi Helen,
sorry for question too specific to ibReplicator.
I still looking for replication SW, because all SW mentioned here
(ibReplicator, symmetricds, CopyCat) has some issues.
Or experience with writing it by self from someone who already did it.
Thank you for understanding.

Ing.
Thank you,
I was try and I found few problems.
1. I failed to set up replication on Db Event (in manual is mentioned).
Any idea how to do with IBreplicator?
2. I failed to transfer all table operation.
Only last values are transfered.
This fail, if is circular link between records like
record A

Hi all,
we are preparing new project with bidirectional replication.
Customer idea is to have master database in head quoter
and slave databases on production plant (to solve network performance
and availability issues).
Witch replication SW you can recommend for this bidirectional replication?
