Version 8.0.1

Enhancements

• The driver package now includes debugging symbols that can be used for diagnosing and debugging issues in the driver. For UNIX, the symbols are embedded directly in the driver binaries, while for Windows, they are stored in separate .pdb files.*
• The driver is now compiled with a Visual Studio 2022 compiler for the Windows platforms. As a result, you must have Microsoft Visual C/C++ runtime version 14.40.33810 or higher on your machine to run the driver.
• The ICU library files that are installed with the Windows version of the product have been upgraded to version 74.1. In addition, the ICU library file names have changed. For the 32-bit driver, the ICU file name has changed from ivicu28.dll to ivicu.dll. For the 64-bit driver, the ICU file name has changed from ddicu28.dll to ddicu.dll. This upgrade is available starting in build 08.02.1072 of the ICU library files.*
  
• The ICU library files that are installed with the Linux version of the product have been upgraded to version 74.1. In addition, the ICU library file names have changed. For the 32-bit driver, the ICU file name has changed from libivicu28.so to libivicu.so. For the 64-bit driver, the ICU file name has changed from libddicu28.so to libddicu.so. This upgrade is available starting in build 08.02.0965 of the ICU library files.*
• The driver has been enhanced to support SAP BW/4HANA and other SAP ODATA V2 services exposed through the SAP NetWeaver Gateway. Refer to Supported SQL statements and extensions for details.
  
• The driver has been enhanced to support CDS views that require parameters. Refer to CDS views for details.
  
• The driver has been enhanced to support HTTP Header authentication for use with the S/4HANA sandbox hosted at https://api.sap.com. Refer to HTTP header authentication for details.
  
• The driver has been enhanced to determine the maximum size of VARCHAR columns within the result set metadata using the new Maximum Varchar Size connection option. Refer to Maximum Varchar Size for details.
  
• A Password Encryption Tool, called ddencpwd, is now included with the product package. It encrypts passwords for secure handling in connection strings and odbc.ini files. At connection, the driver decrypts these passwords and passes them to the data source as required. See Password Encryption Tool (UNIX/Linux only) for details.*
• The driver has been enhanced to support a default value of 100000 for the Web Service Fetch Size connection option. Refer to Web Service Fetch Size for details.
  
• The curl library files that are installed with the product have been upgraded to version 7.75.0, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html. This upgrade is available starting in build 08.02.0239 of the curl library files.

Changed Behavior

• The installer program now requires you to install a JRE that is Java SE 11 or higher before running the installer. In earlier versions, the JRE used by the installer program was included in the product. However, to avoid potential security vulnerabilities, the installer program no longer includes a JRE. Instead, the installer program uses the JRE in your environment to allow for the most secure version of a JRE to be used.

  Notes:

  • This change does not affect the JVM requirements for the driver. For the latest driver requirements, refer to the Product Compatibility Guide.
  • The installer program cannot remove the already installed JRE files from the install directory automatically. Remove them manually.
  • To install the 32-bit drivers on 64-bit Windows platforms and start the SQL engine service, the installer requires the 32-bit version of Java SE 11 or higher installed on your machine and defined on your path.
• The product package no longer includes the ODBC Cursor library file (odbccurs.so) because it has some known security vulnerabilities that could potentially expose you to security risks.*
  Note: The installer program cannot remove the ODBC Cursor library file automatically while installing a new version of the driver. Remove it manually.
• The installer program has been updated to no longer install common components for drivers that do not use them. As a result, the installer program no longer installs the following common components for the SAP S/4HANA driver:*
  • OpenSSL library files, such as ivopenssl30.so, ddopenssl30.so, fips.so, and openssl.cnf.
  • Curl library files, such as libivcurl28.so and libddcurl28.so.

  If the files are not used by any other DataDirect driver on your machine, you can safely remove them from existing product directories.

Notes, Known Issues, and Limitations

• The driver does not support specifying values for the same connection option multiple times in a connection string or DSN. If a value is specified using the same attribute multiple times or using both long and short attributes, the connection may fail or the driver may not behave as intended.
• If you attempt to execute Delete operations against SAP OData services that do not support them, the driver will return the following inaccurate error message: "Expected a string but was BOOLEAN." Contact Technical Support if you encounter issues.
• Updating a NULL value in a column associated with a NOT NULL constraint in a schema table updates the value in the respective column as an empty string. To filter based on a NULL value in this scenario, specify an empty string in the WHERE clause of a SQL statement. Contact Technical Support if you encounter issues.
• The driver does not support update or delete operations on services that require E-Tag validation. If you execute update or delete operations on a service requiring E-Tag validation, the driver returns a 428 error.
• The driver does not connect to services specified by the Service List (ServiceList) option that have a different relative path than the standard, which is https://<hostname>/sap/opu/odata/sap.
• When a column without a value is queried, the driver returns a NULL instead of an empty string. All filter operations require the use of empty strings for such columns.
• When specifying a value for the Extended Options (ExtendedOptions) option in the Configuration Manger, the driver currently adds the option and its value to the Connection String field. However, the ExtendedOptions attribute is not supported in Connection Strings; therefore, attempting to connect with the generated connection string or executing a test connect with the configuration manager will result in the an "Invalid attribute in the connection string: XO" error.
  To work around this issue, manually edit the connection string to remove "ExtendedOptions=" from the connection string; then, specify the value of ExtendOptions as semi-colon separated options in the string.
  For example:
  Driver=;HostName=;ExtendedOptions=WorkArounds2=4096, WorkArounds2=8192;
  Becomes:
  Driver=;HostName=;WorkArounds2=4096;WorkArounds2=8192;
• The driver has been designed to handle large result sets that result. However, out-of-memory errors can still occur. The following items outline how to reduce the likelihood of out-of-memory errors for your environment.
  
  • Reduce Fetch Size (FetchSize) to reduce demands on memory. By lowering the maximum number of rows as specified by Fetch Size, you lower the number of rows the driver is required to process before returning data to the application. Thus, you reduce demands on memory and decrease the likelihood of out-of-memory errors.
  • Increase the JVM heap size. By increasing the max Java heap size, you increase the amount of data the driver can accumulate in memory and avoid out-of-memory errors.
• All of the Release 8.0 Core Components (header files, etc.) needed for development of ODBC applications on Linux are installed into the /include directory created by the product installer.
  Please read the notices.txt file in the installation directory for licensing information regarding the ODBC Core Components. Contact your Progress DataDirect representative if you have any questions.
  Developers using programming languages other than C++: The DataDirect ODBC Driver Manager is a C++ shared library. The ODBC Driver Manager can be used with any language that supports loading a C++ shared library; however, if you are using a programming language other than C++, you must take additional steps to ensure that the C++ libraries are initialized properly when loaded. If you are not using C++, consult your compiler documentation for instructions on using C++ shared libraries with your application.
• A default installation of the product on Linux assumes that the value of the LANG environment setting is en_US. If your locale is not set to en_US, the drivers may not return error messages properly. In this case, you must create a symbolic link in the /locale directory that has the same value as the LANG environment setting. This link must point to the /locale/en_US directory.
• The column attributes 1001 and 1002, which were assigned as DataDirect- specific attributes, were inadvertently used as system attributes by the Microsoft 3.0 ODBC implementation. Applications using those attributes must now use 1901 and 1902, respectively.
• Because of inconsistencies in the ODBC specification, users attempting to use SQL_C_NUMERIC parameters must set the precision and scale values of the corresponding structure and the descriptor fields in the Application Parameter Descriptor.
• You may receive a 126 error when adding or configuring a data source stored on a network location. This might be caused by the settings of the User Account Control (UAC) security feature on Windows 10. To work around this issue:
  Important: Implementing this fix disables security safeguards that are designed to protect your machine. Before starting, refer to the following Microsoft documentation for potential risks associated with disabling the UAC feature: http://windows.microsoft.com/en-us/windows/what-are-user-account-control-settings
