Firebird and the Borland Database Explorer
The Borland Database Explorer is available from the Delphi menu via
Database / Explore.
This allows you to
Define a BDE alias
Before you can view information about a database,
you must first
define an alias.
Notice that there are 2 types of BDE aliases
In the Database Explorer, the data displayed and functions you can perform
are different depending on which is selected -
the INTERBASE driver always provides more capability.
- Those based on the BDE INTERBASE driver
- Those based on ODBC
Open/Close the Database Connection
There are several ways to open and close the connection
The default Username/Password is
SysDBA / MasterKey (this does not appear to be case sensitive).
- Double click on the alias name to Open it.
- Right click the alias and select Open and Close
- Highlight the alias and select Object / Open and Object / Close
from the main menu
- Highlight the alias and toggle the first button on the toolbar
(down is Open)
View tables, their data, and their structures
Once a database is Opened, you can select a table
and view its structure and contents.
When looking at the Columns summary, be sure that View
is set for Detail so that you can see all the data.
- The Text tab shows the SQL that creates the table
- The Data tab shows the contents of the table.
Create new tables
First open a Firebird database.
Via the Object / New menu selection,
it is possible to create new objects ... including new tables.
The trick is to first select either an existing object of the same type or
select the header for that type of object.
You can also select New... from the right click popup menu.
Only Firebird databases allow you to create new tables -
Paradox and ForPro databases do not allow this.
Apparently, Domains allow you to define constraints
without specifying a field (column).
Then when you define a table, use the predefined domains to define
the column parameters.
This only works with an INTERBASE alias,
it does not work with an ODBC alias.
Adding Fields (Columns)
With either a new or an existing table, to add a new field (column)
- Right click on Columns and select New...
- You may select one of 11 types
BLOB, CHAR, CSTRING, DATE,
FLOAT, INTEGER, NUMERIC, QUAD, SMALLINT, VARCHAR
(CSTRING, QUAD are not supported by Interbase 5.0, DECIMAL is supported)
- You may select any existing domain from the list
- Set the field name in the left-hand tree view
