Final release of «Native OLE DB Provider for Firebird v4»

Hello Everyone!

We are very pleased to announce the release of final IBProvider v5.32 with support for Firebird v4.

Some of our users have already appreciated our work and started using IBProvider with FB4, including as a linked MSSQL server.

We are grateful to everyone who helped us.

Special thanks to Marek D., who initiated this process.

General overview of FB4 support in IBProvider

  • The direct connection and connection through fbclient.dll are supported
  • The 63-symbols object names are supported
  • Provider supports the following new datatypes (including arrays):
    • INT128
    • NUMERIC on INT128 base
    • DECFLOAT(16)
    • DECFLOAT(34)
  • Provider supports two mode for processing time zones:
    • Through own algorithms
    • Through external library (ICU)
  • The support of the following queries was implemented:
    • SET BIND
  • Provider executes ALTER SESSION RESET before reusing of the connection. Example
  • The new connection initialization properties were added.

In addition to the above, we have significantly improved the existing functionality.

Therefore, it makes sense to upgrade even if you are not yet planning to move to FB4 or are working with InterBase.

With Best Regards, IBProvider Team.

Release of IBProvider v5.31

Hello Everyone!

We have completed the third step in the process of implementing FB4 support in our OLE DB provider.

This release adds support for TIMESTAMP WITH TIME ZONE, improves support for INT128 and improves support for NUMERIC data types.

Please review the changes carefully.

At the end of the news we have prepared a special offer for you.

Kind Regards, IBProvider Team.

Firebird External Table Generator (ext-table-gen) 1.0 released

I am happy to announce the release of “Firebird External Table Generator” (ext-table-gen for short).

“Firebird External Table Generator” is a commandline tool to transform RFC 4180 CSV files to Firebird external table files (a binary format for external table data).

External tables are a good way for bulk-loading data into Firebird. Unfortunately, external tables use a fixed-width binary format, and not (more) standard formats like CSV. It is not always easy to create an appropriate external table file, and this is where ext-table-gen can be used.

At a high level, ext-table-gen provides the following features:

  • Derive a CHAR-based external table definition (i.e. a CREATE TABLE statement and a configuration for ext-table-gen) from a CSV file
  • Transform a CSV file to an external table file (either based on the CSV file itself, or based on a configuration file)

The current version only supports CHAR columns, which makes the generated file essentially a fixed-width text format. Future versions may introduce support for additional column types.

You can find the 1.0 release at ext-table-gen v1.0.

IBProvider v5.30. DECFLOAT and improved connection pool [FB4]

Hello Everyone.

In the current release, we have continued expanding the support of Firebird v4.

New features

  • The full support of DECFLOAT(16) and DECFLOAT(34) has been implemented
  • The new version of IBProvider supports the ICU v63 from FB4 kit
  • Using «ALTER SESSION RESET» for resetting a connection before reusing (see this new example)

Kind Regards and Good Luck! IBProvider Team.

IBProvider v5.29. The initial support of FB4

Hello All 🙂

The implementation of FB4 support requires time. That is why we decided to split this process into parts and make intermediate releases. It will allow you to begin using IBProvider with FB4 right now.

The current support of FB4

  • You can work with FB4 through fbclient.dll
  • You can work with FB4 through a built-in client ( The 13th protocol will be used
  • The long name of database objects are supported
  • All the FB4 datatypes (including new datatypes: INT128, DECFLOAT, time/date with a time zone) are supported at the metadata layer
  • The full support of INT128 and NUMERIC on base INT128 was implemented
  • New initialization properties were added — int128_rulesnumeric_i16_rules

Lots of functional and load tests were made with using FB v4.0.3.2937.

For mission-critical, multi-threaded and 24/7 applications, we highly recommend using the built-in client.

IBProvider Free does not support FB4.

Additional changes

  • The support of DBTYPE_TIMESTAMPOFFSET was added
  • The transformation between {DBTIME, DBTIME2} and {DATE, DBDATE, DBTIMESTAMP, FILETIME} was deleted
  • The transformation of NUMERIC into VARIANT was improved
  • The procession of charset names was corrected

With best regards, IBProvider Team.
