Developer ProductivityIn SQL Anywhere 12.0.1, new developer productivity features include several new stored procedures anddatabase options, SQL language enhancements, and the implementation of UltraLite support for Androidsmartphone and tablet devices.Enhanced Database ManagementSQL Anywhere 12.0.1 has implemented several new system stored procedures, server parameters, anddatabase options that control many aspects of the database behavior. For instance, you can now specify theserver principal used by the database server for Kerberos authentication. Another example is the ability toprovide each database with an additional set of directories or JAR files in which to search for whenexecuting Java objects in the database, a useful option when your application must provide the directoriesor JAR files.SQL Anywhere supports database mirroring and Veritas Cluster Server to provide high availability. This isdone through the configuration of either two or three database servers, running on separate computers,which co‐operate to maintain copies of the database and transaction log files. Database mirroringenhancements have been made to the PartnerState property and the MirrorServerState property to allowfor better management of a high availability environment. These properties now return the following valueswhen used with their corresponding Property functions:• Connected• Incoming only• Outgoing only• Disconnected• NULLImproved SQL LanguageImprovements to the SQL language have added additional functionality and flexibility within the program,letting you do more. The following are some of the new statements and clauses that can be utilized in SQLAnywhere 12.0.1:• IN parameters of data types LONG VARCHAR, LONG BINARY, and LONG NVARCHAR now allowedin remote procedure calls• USING clause of the CREATE SERVER statement can now contain variables• AT clause of the CREATE EXISTING TABLE statement and CREATE PROCEDURE statement can nowcontain variables• Enhancement to the RAISERROR clause of the MERGE statement and to the RAISERROR statement• VALIDATE TEXT INDEX statement• Extended syntax for TOP and LIMIT clausesSQL Anywhere 12.0.1New Features Summary – February 2011
Additional Driver SupportSQL Anywhere 12.0.1 offers improved support for JDBC. JDBC is a call‐level interface for Java applications,providing you with a uniform interface to a wide range of relational databases, and a common base onwhich higher level tools and interfaces can be built.The JDBC driver now supports the following PreparedStatement.setClob methods for improvedperformance and memory usage when working with large strings and large character streams:PreparedStatement.setClob( int parameterIndex, Clob x )PreparedStatement.setClob( int parameterIndex, Reader reader, long length )Java and .NET ImprovementsThe SQL Anywhere Java VM ClassLoader which is used in providing Java in the database support now allowsapplications to install shutdown hooks. These shutdown hooks are very similar to the shutdown hooks thatapplications install with the JVM Runtime. When a connection that is using Java in the database supportexecutes a STOP JAVA statement or disconnects, the ClassLoader for that connection will now run allshutdown hooks that have been installed for that particular connection prior to unloading.The .NET SetupVSPackage application now performs several installer functions such as updating the GlobalAssembly Cache and the Windows Microsoft.NET machine.config file. In addition, if SQL Server 2008 or lateris installed on the system, .NET SetupVSPackage also installs mapping files to import and export datato/from SQL Anywhere.UltraLite EnhancementsThe UltraLite database now supports Android smartphone and tablet devices. You can use the Androidimplementation of the UltraLiteJ API to create feature rich applications that use UltraLite databases. Datasynchronization is also enabled between a consolidated database and an UltraLite database running on theAndroid device.SQL Anywhere 12.0.1New Features Summary – February 20115
