How to find the procedures, trigger and views, that do not use an index in their operations?

Just open menu Tools-Stored Procedure/Trigger/View Analyzer and press F9. This analyzes all objects and
shows parts that do not use an index in red color. To modify these objects, just double click the line. A
well designed database should have no red line.

How to find the procedures and triggers that have typical type casting problems?

A typical problem that is often not so easy to find is when a varchar(20) column is copied into a varchar
(10) variable. In most cases it makes no problem, but when the source has more than 10 characters you get a
runtime error. This will typically only happen in your customers database. To find these errors, just open
menu Tools-Stored Procedure/Trigger/View Analyzer and press F9.

How to know if your database servers garbage collection is working?

Just open your database, open menu Services-Database Statistics and press F9. On the summary page you can
see a versions column with subcolumns versions, version length and max versions. When the garbage collection
works properly, there should be only very low values for versions and max versions. When there are higher
values, your garbage collection do not work propery, which might have several reasons, typically improper
transaction handling in your application.

How to change the Character Set of all tables in a database?

How to compare different hardware and database server concerning the speed?

We recommend to use the IBExpert Demo Database script in program filesHK-SoftwareIBExpertDemoDBdb1.sql.
This creates a simple shop database. When executing the procedure initall with a parameter 10000, it creates
10000 customers, 10000 products etc. All in all there are 750000 operations in the database, which will have
a size of 25 MB.It should run between 10 and 20 seconds. For creating a larger database, just use a larger
parameter, for example initall(100000) creates a database of about 250 MB with about 7.5 million operations
etc. For using this script with Interbase, please replace the select first 1 syntax to select …. rows 1 in
the script before executing it. Firebird 2 showed a speed improvment of about 75 % compared to firebird 1.5
