ODBCSchema is a tool for browsing and printing table layouts, and browsing tables. It also have a special mode for copying data from one table to another. Tested with Primebase ODBC 3 & 4, and with Butler ODBC. Some minor quirks with Butler ODBC still there.
Enhancements:
- ODBC-Schema is now freeware and openscource.

Databrid is a tool designed for browsing, retrieval and manipulation tool designed for the novice to the expert user. Databrid works on an Oracle Database (versions 8 and above although not all functionality in the Browser is available for the lower versions).
The core functionality of Databrid revolves around the tabbed areas within the Databrid application. The four main tabs in the main screen of Databrid are: SQL Editor, Browser, File and Jobs.
SQL Editor
The SQL Editor tab allows you to write and run SQL and PLSQL.
The tab provides the ability to use one of more syntax highlighting editors with automatic case adjustment for keywords. Provided with each editor is a table for displaying SQL query results and a text output area to display DBMS_Output output. Jobs can be run in the background allowing for the execution of multiple statements at any given time.
Browser
The Browser tab allows the you to browse various parts of the database schema.
The browsing is done via a particular schema user and displays information on tables, views, sequences etc.
Features include the generation of database creation statements for tables, views etc, browsing table or view data, truncating tables, etc.
File
The File tab allows you work with a CSV (comma delimited text file) and the database without having to load the CSV into the database.
This tab has two areas that functionality:
CSV Update and Database Update. CSV Update allows you to add additional columns to a CSV using a Select statement, including binding CSV column values to the Select statement.
Database Update allows you to update the database using insert, updates, deletes or PLSql by binding the CSV column values into your statement.
Jobs
This tab allows you to view which jobs (started from the SQL Editor and File tabs) are
currently running or have finished. Jobs that are running can also be stopped.
Enhancements:
- Connections to MySql may not work correctly if the Oracle drivers are not in the include path. This may affect some versions of the Oracle drivers as well.
- Schema browser not working for Oracle if the user had select on all tables but no access to the dba views. Thanks to Mike Taylor in helping to fix this issue.
