How to Use EMS Data Export with InterBase and Firebird — Step-by-Step Tutorial

Overview

This tutorial shows a concise, prescriptive workflow to export data from InterBase or Firebird using EMS Data Export. Assumes EMS Data Export is installed and you have database credentials and network access.

1. Prepare environment

1. Backup: Make a full database backup (gbak) or export copy before changes.
2. Install: Ensure EMS Data Export (compatible version) is installed on Windows.
3. Drivers: Verify Firebird/InterBase client libraries (fbclient.dll/ibclient.dll) are present and accessible (same folder or PATH).
4. Credentials: Have server, database path, username, and password ready.

2. Create a new project

1. Launch EMS Data Export.
2. Choose File → New (or New Project).
3. Select InterBase/Firebird as data source.
4. Enter connection parameters: server (or local file path), database file, username, password, port (default 3050).
5. Click Connect and confirm you can browse tables.

3. Select tables and queries to export

1. In the database tree, check the tables you want to export.
2. To export a custom dataset, create a SQL query: click Query → New Query, write SELECT … and run to preview rows.
3. Use filters or WHERE clauses to limit rows.

4. Choose export format and options

1. Click Export (or Export Data).
2. Choose output format (CSV, Excel, XML, JSON, SQL, SQL INSERTs, DBF, etc.).
3. Configure format-specific options:
   • CSV: delimiter, quote, encoding (UTF-8/ANSI), header row.
   • Excel: sheet name, XLS vs XLSX.
   • SQL: generate CREATE TABLE, INSERT statements, BLOB handling.
4. Set output folder and filename mask. Optionally enable per-table files.

5. Map fields and set transformations (optional)

1. Use Field Mapping to reorder, rename, or exclude columns.
2. Apply simple transformations (format dates, numeric precision, default values) if the tool provides them.

6. Configure export behavior

1. Set batch size or transaction options for large exports.
2. For large BLOBs, enable streaming or file extraction if supported.
3. Choose whether to wrap output in a single transaction or commit per batch.

7. Run export and monitor

1. Click Start or Export.
2. Monitor progress window for errors or warnings.
3. If errors occur (connection drop, permissions), fix and re-run; partial exports can often resume depending on format.

8. Validate exported data

1. Open output files in appropriate viewer (Excel, text editor, JSON viewer).
2. Compare row counts and sample values with source DB.
3. For SQL exports, try importing into target DB in a test environment.

9. Automate (optional)

1. Save project (.dpr or tool-specific project file).
2. Use command-line interface (if EMS provides) to run saved projects via a scheduled task.
3. Schedule Windows Task Scheduler job for recurring exports.

10. Troubleshooting tips

• Connection failures: check client library, firewall, port, and correct path.
• Permission errors: ensure the DB user has SELECT privileges on tables.
• Encoding issues: try UTF-8 or appropriate character set for your data.
• Large exports slow: increase batch size, disable indexes on import target, or export to multiple files.

Quick checklist

• Backup made
• Client library present
• Connection successful
• Export format & options set
• Field mappings reviewed
• Export run and validated
• Automation saved (if needed)
