Micorosoft SQL Server JDBC 3.0 Released!!!

  • Articolo

Dear SQL Server developers and users:

On behalf of Microsoft SQL Server JDBC team I am very excited to announce our latest JDBC driver Microsoft SQL Server JDBC 3.0 release.

This version of the JDBC driver provides support for features introduced in SQL Server 2008, which includes date and time data types, sparse columns, MERGE statements and large user-defined types (UDTs). The support for the new date and time data types includes new setter, getter, and updater methods for SQL Server time, date, datetime2 and datetimeoffset data types. Support for large UDTs includes handling CLR UDTs that are larger than 8000 bytes as binary data. Also, this release adds interfaces for unwrap and isWrapper in the Wrapper interface. In addition, this release enhances metadata support by adding sparse column metadata and new date and time metadata.

Thank you for providing great feedback on our CTP. We really appreciate your continued support on our driver. Feel free to download a copy and check it out!

Thank you,

Amina Saify - JDBC

    Environment OS: Vista HP SP2 x64 SQLServer: 2008 R2 x64 Java: 6u20 x64 Driver: sqljdbc4-3.0.jar Running a Java app for retrieving some metadata, the driver still returns java.sql.Types.NVARCHAR for 'date', 'time' and 'datetime2' database types, rather than java.sql.Types.DATE/TIME/TIMESTAMP respectively, which is what I expected. What is the reason that the Java app (or the JDBC driver itself?) is treated as a "down-level client"?

    Do you have a concise repro you can share with us. The 2.0 driver returned nvarchar but the 3.0 should not. Are you sure that you are picking up the right jar? I would print the version of the jar in my application via getDriverVersion()

    We'd like to be able to associate a user with a connection during the time we have it out of the pool.  Oracle lets you run "DBMS_SESSION.SET_IDENTIFIER" with the user name.  Is this possible with the 3.0 MS JDBC driver?  I tried playing around with the Connection.setClientInfo() and .getClientInfo() without luck.

    It looks like the documentation is not correct here. From 3.0 the varchar(max) will be reported as varchar and similarly varchar(binary). If you want to know if the type is max type or standard type you have to also use precision to determine whether the type is max type or small type.

    If we could modify applicationName cheaply and dynamically, we could slip in the user name.

    How about a UDT example?  I can't seem to find any documentation on how to use it.
