Version 12.6 of the Microsoft JDBC Driver for SQL Server has been released. Version 12.6.0 brings several added features, changes, and fixed issues over the previous production release.

Added

• Added connection property, useDefaultJaasConfig, to allow Kerberos authentication without any additional external configuration #2147
• Allow calling of stored procedures directly in CallableStatements, simplifying the procedure and improving performance #2154
• Added connection property, useDefaultGSSCredential, to allow the driver to create GSSCredential on behalf of a user using Native GSS-API for Kerberos authentication #2177
• Added Java 21 support #2229
• Added connection property, calcBigDecimalPrecision, to allow the driver to calculate scale and precision from Big Decimal inputs #2248
• Added a new named logger for connection open retries and idle connection resiliency reconnects #2250

Changed

• Adjusted PreparedStatement cache, so it's cleared before every execute #2272
• Updated azure-identity, azure-security-keyvault-keys, bouncycastle, and msal library versions #2279
• Changed socketTimeout to ensure it's always less than or equal to loginTimeout #2280
• Change BulkCopy behavior from serializing and deserializing Timestamp objects, to using the objects directly #2291
• Changed how IBM JDK is checked for to prevent issues with OSGi environments #2150
• Updated azure-security-keyvault-keys, bouncycastle, and h2 library versions #2162 #2182 #2249
• Changes to bulkcopy to allow for performance improvements when loading a large number of timestamps #2194
• Added additional errors that should translate to RMFAIL #2201
• Properly synchronize all calls to MSAL, preventing the driver from making extra calls and providing unneccessary dialogues #2218
• Changed driver retry behavior to retry the correct number of times based on connectRetryCount #2247

Fixed issues

• Fixed the way ActivityID was defined and used to be more in line with the behavior of other Microsoft drivers #2254
• Fixed missing getters and setters for useBulkCopyForBatchInsert #2277
• Fixed an issue where, when using the TOP qualifier in a query, the driver returns an error concerning ParameterMetadata #2287
• Fixed an issue where insert statements with missing whitespace worked correctly in regular cases, but not when using batch inserts #2290
• Fixed time zone not being properly applied to Timestamps when inserted using batch insert with bulkcopy #2291
• Fixed locks in IOBuffer to prevent deadlock issues that could arise #2295
• Fixed an issue where, when an exception has no cause, the exception itself is passed along instead, preventing it from being lost #2300
• Fix to ignore irrelevant computed columns during bulk insert #1562
• Fixed an issue where signature was not properly verfied when using Java Key Store, as well as adding a new API to sign column master key metadata (and return generated signature) for use with Java Key Store and Azure Key Vault #2160
• Fixed an issue where a null SQLState was returned when trying to convert a date to a long #2185
• Fixed an issue where schemaPattern was not properly being escaped in SQLServerDatabaseMetadata #2195
• Fixes getObject()'s erroneous conversion of DateTimeOffset to LocalDateTime #2204
• Fixed an issue with ParameterMetadata not properly checking for an invalid index 0 #2217
• Fixed bulkcopy metadata query to make use of cached data, if it's available #2231
• Fixed an issue when writing TVP row values, where input values were not properly filtered for BigDecimal scale #2239

Known Issue

• Localized error strings are not present for languages other than English. This will be addressed in a hotfix.
