Every year on January 18 we have a small celebration – IBProvider’s birthday.

This year it turned 14.

We thank all our users for using the provider in your projects.

We promise that we will continue to improve IBProvider till it completely supersedes Firebird and Interbase :)

Firebird Data Wizard SQL Maestro Group announces the release of Firebird Data Wizard 13.12, a powerful Windows GUI utility for Firebird data management.

Firebird Data Wizard provides you with a number of easy-to-use tools to transfer any database to Firebird, import data into Firebird tables, export data from tables, views and queries to most popular file formats, dump table data to SQL files as well as generate data-driven ASP.NET pages for your database.

New version features updated Data Import and SQL Dump tools, data export to JSON format, redesigned Start Page, and some other useful things.

There are also other useful things as well as versions for other DBMS (MySQL, Oracle, SQL Server, DB2, PostgreSQL, etc). Read full press release.

The Firebird JDBC team is happy to announce the release of Jaybird 2.2.4.

This release contains the following fixes:

  • Fixed: Exceptions during statement preparation leave connection and transaction open after explicit close (JDBC-311)
  • Fixed batch update (or insert) with blob set through setBinaryStream() sets empty blob for all but the first batch entry (JDBC-312)
  • Fixed incomplete checks of database, transaction, statement and blob handle validity before continuing with actions. These incomplete checks could lead to unexpected exceptions (for example a NullPointerException in iscDatabaseInfo) (JDBC-313)
  • Fixed error when setting connection charset equal to "file.encoding" java property (JDBC-314)
  • Fixed connection character set not correctly set when specifying the Java connection characterset (charSet or localEncoding property)  (JDBC-315)
  • Fixed incorrect lengths and/or radix reported by getTypeInfo and getColumns metadata (JDBC-317, JDBC-318)
  • Initial Java 8 / JDBC 4.2 support (JDBC-319)
  • Firebird 3 BOOLEAN type support, see Support for Firebird 3 BOOLEAN type in the release notes for more details (JDBC-321)
  • Added fallback of loading GDSFactoryPlugin implementations to prevent NullPointerException in Hibernate reverse engineering wizard in NetBeans (JDBC-325)
  • Fixed: Jaybird should specify dialect 3 in dpb when no explicit dialect was set (JDBC-327)
  • Fixed: several DatabaseMetaData methods defined by JDBC to only accept the actual table name also accepted a LIKE-pattern or empty string or null. This was changed to conform to JDBC. This change can break applications that relied on the incorrect behavior (JDBC-331)
    Affected methods are: getPrimaryKeys, getBestRowIdentifier, getImportedKeys, getExportedKeys and getCrossReference. As part of this change getIndexInfo now handles names in the wrong case slightly different.
    Jaybird 3.0 will further modify and restrict the pattern matching and case sensitivity of metadata methods. See Future changes to Jaybird in the release notes for more details.

Downloads available from JDBC driver section on the Firebird website.

The release is also available on maven(*):

<groupId>org.firebirdsql.jdbc</groupId>
<artifactId>jaybird-jdkXX</artifactId>
<version>2.2.4</version>

* The artifactId depends on your target Java version: jaybird-jdk15, jaybird-jdk16, jaybird-jdk17 or jaybird-jdk18

ADO.NET provider for Firebird 4.0.0.0 is ready

We continue to develop our .NET Provider for OLEDB. In the new build (#1434), we have implemented the methods to obtain database metadata:

  • OleDbConnection.GetOleDbSchemaTable
  • OleDbConnection.GetSchema

GetOleDbSchemaTable

Supported schemas:

  • SchemaGuids
  • DbInfoKeywords
  • DbInfoLiterals
  • All schemas of the OLEDB Provider

Distinctions compared to standard OLEDB.NET Provider:

  • The SchemaGuids schema describes all schemas including SchemaGuids, DbInfoKeywords and DbInfoLiterals.
  • The SchemaGuids schema supports restrictions for the Schema column.

GetSchema

Supported schemas:

  • MetaDataCollections
  • Restrictions
  • DataTypes
  • ReservedWords
  • DataSourceInformation
  • CharacterSets
  • Collations
  • Tables
  • Views
  • Columns
  • Procedures
  • ProcedureParameters
  • ProcedureColumns
  • Indexes

Distinctions compared to standard OLEDB.NET Provider:

  • The MetaDataCollections schema supports restrictions for the column CollectionName.
  • The Restrictions schema supports restrictions for the columns CollectionName and RestrictionName.
  • More accurate population of the DataSourceInformation schema.
  • More accurate population of the Restrictions schema.

Implementation peculiarities

  • Caching of data from its own schemas (SchemaGuids, DbInfoKeywords, DbInfoLiterals, …).
  • Coherence of information from metadata schemas with the descriptions of the resulting rowset columns and command parameters (ensured by IBProvider).
  • Different algorithms of metadata loading for Interbase and Firebird. Including – our provider takes into account the version of the server and the version of database ODS (ensured by IBProvider).
  • Caching of OLEDB metadata schemas is carried out on the IBProvider level (see a property «schema_cache»).

Other changes

  • The OleDbSchemaGuid class added with the lists of known OLEDB schema identifiers.
  • The OleDbSchemaRestriction class added with the lists of restriction indexes for known OLEDB schemas.
  • The OleDbLiteral class added.
  • The OleDbMetaDataCollectionNames class added.
  • The number of tests and debug structures ensuring the correct work of components increased.

New examples
