Updates in 1.50 release VI. Issues __________________________________________________________________ Updates in 2.50 release Current version: InterClient 2.50 * This release communicates with InterBase 6.5 using JRE 1.3. You can download JRE 1.3 from http://java.sun.com/j2se/1.3/jre/ * New public classes, methods and fields: Added Quoted Identifier support for InterBase 6 and dialect 3 onwards... interbase.interclient.DatabaseMetaData.supportsMixedCaseQuotedIdentifiers() interbase.interclient.DatabaseMetaData.storesMixedCaseQuotedIdentifiers() interbase.interclient.DatabaseMetaData.getIdentifierQuoteString() Added support for getBigDecimal() without the 'scale' parameter interbase.interclient.ResultSet.getBigDecimal(int) interbase.interclient.ResultSet.getBigDecimal(String) __________________________________________________________________ Updates in 2.01 release * This release communicates with InterBase 6.0.1 using JRE 1.3. You can download JRE 1.3 from http://java.sun.com/j2se/1.3/jre/ * Licensing is now reinstated in InterClient 2.01 * New public classes, methods and fields: interbase.interclient.Connection.setReadOnly() interbase.interclient.ConnectionProperties interbase.interclient.DatabaseMetadata interbase.interclient.DatabaseMetadata.isReadOnly() interbase.interclient.DatabaseMetadata.getDatabaseSQLDialect() interbase.interclient.ResultSet (DATE, TIME and TIMESTAMP support) interbase.interclient.ResultSet (DECIMAL and NUMERIC INT64 support) * New error codes interbase.interclient.ErrorCodes InvalidOperationException__database_is_readOnly_ SQLDialectAdjustmentWarning * DATE columns in ODS 9 will now be reported as having the Interbase Type Name of 'TIMESTAMP' * The operation Statement.setMaxRows(int numRows) is correctly interpreted by InterClient. A result set will contain the specified number of rows. __________________________________________________________________ Updates in 1.6 release * This driver (1.6) does not need a license file. __________________________________________________________________ Updates in 1.51 release * Java 2 compatibility and bug fixes. __________________________________________________________________ Updates in 1.50 release * This release communicates with InterBase 5.x under the JRE 1.1 * Big performance improvements. We may now be the fastest driver on the market. * Interclient is now completely localized, with easily translatable resource bundles for all error messages and hard-wired text used by the driver. Customizable public resource bundles for both InterClient and CommDiag are provided to accomodate international applications. See API reference for interbase.interclient.Resources and interbase.interclient.utils.Resources. * Direct international support for user-specified character sets. InterClient supports 20 of the 22 InterBase character set encodings, including Unicode FSS. Data is transliterated directly using native encodings, this provides much better performance than drivers that use only a single universal encoding on the wire. See the API reference for interbase.interclient.CharacterEncodings for a list of supported encodings. All SQL, CHAR, VARCHAR, and blob character result/parameter data are encoded and decoded using the encoding specified with the charSet connection property. * Improved documentation accessible through the JBuilder help viewer. The InterClient Programmer's Guide has been renamed InterClient Introduction, and the Reference and Help documentation has been extended. The API Reference now has links to JavaSoft's core API documentation. See docs/index.html in the InterClient distribution. * Various capability and robustness enhancements to the API in general, especially in the area of input parameter and result column type conversions. For example, prepared statement parameter conversions now distinguish between character blobs and binary blobs, disallowing certain operations such as setString() on a binary blob and allowing operations such as setBytes() on a character field according to the JDBC conversion tables. * Full support for SQL DESCRIBE and SQL DESCRIBE INPUT functionality. PreparedStatement.getMetaData() provides a way to access result set meta data before a prepared statement is executed. ParameterMetaData off a PreparedStatement provides a way to get metadata describing the input parameters to a prepared statement. This functionality is an extension to the base JDBC API. * Configurable local row cache size. See API reference for interbase.interclient.Statement.setFetchSize(). * SQL State codes associated with driver generated exceptions are now published. See the Help documentation. * Improved error messages. * New public classes, methods and fields: interbase.interclient.BlobIOException interbase.interclient.CharacterEncodings interbase.interclient.CharacterEncodingException interbase.interclient.ErrorCodes interbase.interclient.Resources interbase.interclient.UnsupportedCharacterSetException interbase.interclient.ConnectionProperties.setCharacterEncoding() interbase.interclient.PreparedStatement.getMetaData() interbase.interclient.Statement.setFetchSize() interbase.interclient.Driver.getCompatibleJREVersions() interbase.interclient.Driver.getCompatibleIBVersions() interbase.interclient.Driver.getBuildCertificationLevel() interbase.interclient.Driver.testBuild interbase.interclient.Driver.betaBuild interbase.interclient.Driver.finalBuild * Discarded packages, interfaces, classes and methods: interbase.interclient.netscape_utils Driver.asString() BadInstallation() constructor ComponentException Monitor and monitoring facility DatabaseNotCapableException is now subsumed by DriverNotCapableException All exception class member methods * All driver methods are tagged in the API Reference according to origination: JDBC 1, JDBC 2, or Extensions. Method deprecations are also noted in Reference. * Class inheritance changes to exception classes. * Renamed classes and methods: LoginTimeoutException is now SocketTimeoutException * VARCHAR fields are no longer right trimmed by the result set Adaptor.RIGHT_TRIM_STRINGS directive. * Non-zero error codes are now generated for driver generated exceptions. * More fully qualified version strings for InterClient and InterServer, including build numbers and certfication levels. * Classes are no longer distributed in a single interclient.jar file, rather the following Java archives are distributed: interclient-core.jar The JDBC driver with only the default American English text resources. No utilities are included in the core jar file. interclient-res.jar Locale specific resource bundles. interclient-utils.jar Utilities, this jar file consists of the communications diagnostics utility. interclient.jar JDBC driver, all resources, and utilities. * DatabaseMetaData system table queries now return VARCHAR (vs. CHAR) data for InterBase metadata such as table, column and procedure names. So metadata is no longer right padded with blanks as CHAR data is. * CommDiag improvements. * Examples directory added to distribution with sample Java programs which use InterClient. * Configurable TCP/IP port numbers for InterServer. By default, InterServer listens on port 3060, but this port may be modified manually if necessary. If a port other than 3060 is used, it must be specified in the database or server URL syntax. See Help documentation. * Open Source. The source for InterClient/InterServer is available at www.interbase.com. The terms of the license are in the files InterBase_Public_license.* __________________________________________________________________ Issues Please be aware of the following issues affecting this release of InterClient: * InterBase table names and other metadata must have an ASCII representation. * DatabaseMetadata.getProcedureColumns returns 0 for precision values for NUMERIC and DECIMAL columns rather than the correct precision. * DatabaseMetadata.getColumns does not return the proper default value of a column in an InterBase table. __________________________________________________________________ Copyright (c) 2001 Borland Software Corporation All rights reserved.
