Jaybird 3.0.6 released

We are happy to announce the release of Jaybird 3.0.6.

This release is largely a bugfix release, but contains additional support for Firebird 4.

Jaybird 3.0.6 contains the following fixes and changes:

  • Fixed: Exceptions during fetch of cached result sets (holdable over commit, scrollable and metadata) prevented prepared statement reuse/re-execute with error “Statement state CURSOR_OPEN only allows next states [CLOSING, PREPARED, ERROR], received EXECUTING” (JDBC-531)
  • Improvement: Added FBManager.setDefaultCharacterSet to set default database character set during database creation (JDBC-541)
  • New feature: Support for Firebird 3 case sensitive user names (JDBC-549)
  • Fixed: Savepoints did not work in connection dialect 1 as savepoint names were always quoted (JDBC-556)
  • Changed: The DatabaseMetaData statement cache introduced in Jaybird 3 was unlimited, it is now limited to 12 prepared statements; the least recently used statement will be closed and removed when a new statement is added (JDBC-557)
  • Fixed: UPDATE OR INSERT with existing RETURNING clause handled incorrectly for generated keys (JDBC-566)
  • Fixed: Exceptions during initialization of result sets would not properly close the database cursor leading to error “Current statement state (CURSOR_OPEN) does not allow call to prepare” on reuse of the statement (or errors similar to described for JDBC-531 above). (JDBC-571)
  • New feature: boolean connection property ignoreProcedureType to disable usage of metadata for stored procedure types in CallableStatement When set to true>, call escapes and EXECUTE PROCEDURE will default to use EXECUTE PROCEDURE and not switch to SELECT for selectable stored procedures. (JDBC-576)
  • New feature: connection properties timeZoneBind and sessionTimeZone for limited support for Firebird 4 TIME(STAMP) WITH TIME ZONE types, and decfloatBind for limited support for Firebird 4 DECFLOAT types. (JDBC-538)
  • Fixed: Connection property defaultIsolation/isolation did not work through DriverManager, but only on DataSource implementations. (JDBC-584)

Jaybird 3.0 supports Firebird 2.0 and higher, on Java 7, 8 and 9 and higher. Basic Java 9 and higher compatibility is provided through the Java 8 version of the driver.

Jaybird 3.0.0-alpha-1 release for testing

Jaybird 3.0.0-alpha-1 has been published for testing. We would really appreciate if you could start testing your applications with this version and provide feedback on stability and behavior, but also on the release notes.

Feedback can be sent to the Firebird-java mailinglist or on the issue tracker http://tracker.firebirdsql.org/browse/JDBC.

Jaybird 3.0 is a big change from Jaybird 2.2 and earlier. We have rewritten the entire low-level implementation to be able to support protocol improvements in newer Firebird versions, made changes with a stricter interpretation of the JDBC requirements, and removed some parts that were either obsolete or not functioning correctly.

We recommend that you do not consider Jaybird 3.0 a drop-in replacement for Jaybird 2.2, and study the release notes carefully.

See:

Jaybird 3.0 Alpha 1 is available from Maven central:

Groupid: org.firebirdsql.jdbc,
Artifactid: jaybird-jdkXX (where XX is 17 or 18).
Version: 3.0.0-alpha-1

For example:

<dependency>
     <groupId>org.firebirdsql.jdbc</groupId>
     <artifactId>jaybird-jdk18</artifactId>
     <version>3.0.0-alpha-1</version>
</dependency>

If your application is deployed to a Java EE application server, you will need to exclude the javax.resource:connector-api dependency, and add it as a provided dependency:

<dependency>
     <groupId>org.firebirdsql.jdbc</groupId>
     <artifactId>jaybird-jdk18</artifactId>
     <version>3.0.0-alpha-1</version>
     <exclusions>
         <exclusion>
             <groupId>javax.resource</groupId>
             <artifactId>connector-api</artifactId>
         </exclusion>
     </exclusions>
</dependency>
<dependency>
     <groupId>javax.resource</groupId>
     <artifactId>connector-api</artifactId>
     <version>1.5</version>
     <scope>provided</scope>
</dependency>

If you want to use Type 2 support (native, local or embedded), you need to explicitly include JNA 4.2.2 as a dependency:

<dependency>
     <groupId>net.java.dev.jna</groupId>
     <artifactId>jna</artifactId>
     <version>4.2.2</version>
</dependency>

Jaybird 2.2.4 released

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

Jaybird 2.2.3 (Firebird JDBC) released

The Firebird JDBC team is happy to announce the release of Jaybird 2.2.3.

See http://www.firebirdsql.org/en/jdbc-driver/ for the downloadlinks.

The release is also available on maven:
<groupId>org.firebirdsql.jdbc</groupId>
<artifactId>jaybird-jdkXX</artifactId>
<version>2.2.3</version>

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

The following has been changed or fixed in Jaybird 2.2.3:

  • Fixed incorrect synchronization in native and embedded protocol (JNI) implementation for iscBlobInfo and iscSeekBlob (JDBC-300)
  • Fixed holdable ResultSet is closed on auto-commit (JDBC-304, JDBC-305)
  • Fixed table names missing or padded with spaces in Database view of IntelliJ IDEA (JDBC-308, IDEA-100786)
  • Fixed incorrect JDBC minor version reported under Java 7; this resulted in an incorrect column name (for Java 7) in the metadata of DatabaseMetaData.getColumns(…) (JDBC-309)
  • Added IOException to cause of GDSException with error 335544721; “Unable to complete network request to host “”” for further investigation (JDBC-306)

More details are available in the Jaybird 2.2.3 releasenotes.

Jaybird 2.2.2 Released

The Firebird JDBC team is happy to announce the release of Jaybird 2.2.2.

See http://www.firebirdsql.org/en/jdbc-driver/ for the downloadlinks.

The release is also available on maven:
<groupId>org.firebirdsql.jdbc</groupId>
<artifactId>jaybird-jdkXX</artifactId>
<version>2.2.2</version>

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

The following has been changed or fixed in Jaybird 2.2.2:

  • Fixed: FBMaintenanceManager.listLimboTransactions() reports incorrect transaction id when the result contains multi-site transactions in limbo (JDBC-266)
  • Fixed: Calling PreparedStatement.setClob(int, Clob) with a non-Firebird Clob (eg like Hibernate does) or calling PreparedStatement.setClob(int, Reader) throws FBSQLException: “You can’t start before the beginning of the blob” (JDBC-281)
  • Fixed: Connection property types not properly processed from isc_dpb_types.properties (JDBC-284)
  • Fixed: JNI implementation of parameter buffer writes incorrect integers (JDBC-285, JDBC-286)
  • Changed: Throw SQLException when calling execute, executeQuery, executeUpdate and addBatch methods accepting a query string on a PreparedStatement or CallableStatement as required by JDBC 4.0 (JDBC-288)
    NOTE: Be aware that this change can break existing code if you depended on the old, non-standard behavior! With addBatch(String) the old behavior lead to a memory leak and unexpected results.
  • Fixed: LIKE escape character JDBC escape ({escape ‘<char>’}) doesn’t work (JDBC-290)
  • Added: Support for a connect timeout using connection property connectTimeout. This property can be specified in the JDBC URL or Properties object or on the DataSource. If the connectTimeout property is not specified, the general DriverManager property loginTimeout is used. The value is the timeout in seconds. (JDBC-295)
    For the Java wire protocol the connect timeout will detect unreachable hosts. In the JNI implementation (native protocol) the connect timeout works as the DPB item isc_dpb_connect_timeout which only works after connecting to the server for the op_accept phase of the protocol. This means that – for the native protocol – the connect timeout will not detect unreachable hosts within the timeout. As that might be unexpected, an SQLWarning is added to the connection if the property is specified with the native protocol.
  • As part of the connect timeout change, hostname handling (if the hostname is an IP-address) in the Java wire protocol was changed. This should not have an impact in recent Java versions, but on older Java versions (Java 5 up to update 5) this might result in a delay in connecting using an IP-address, if that address can’t be reverse-resolved to a hostname. Workaround is to add an entry for that IP-address to the /etc/hosts or %WINDIR%\System32\Drivers\etc\hosts file.
