Version History ==============================================================

1.4.28 -----------------------------------------------------------------------

Released 2021-04-30

Enhancements & New Features

  • [PGODBC-1339] Updated OpenSSL library

The connector has been updated to use version 1.1.1i of the OpenSSL library. Previously, the connector used 1.1.1g.

  • [PGODBC-1358] Updated dynamically linked libraries for Linux

The connector has been updated to use the following libraries: - libstdc++ version 6.0.21 or later (previously 6.0.20 or later) - GCC 5.5 or later (previously 4.9 or later)

Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Connector 1.4.28.

  • [PGODBC-1038] When executing multiple concurrent queries in the same connection, the connector terminates unexpectedly.

  • [PGODBC-1206] When querying SQLSpecialColumns(), the connector returns incorrect results.

  • [PGODBC-1260] On Linux, when calling ODBC API calls such as SQLGetCursorName(), the connector returns a bad_alloc exception.

This issue has been resolved. This is caused by an overflow when computing the buffer size. The connector now returns a warning if the buffer size is not appropriate.

  • [PGODBC-1281] When calling SQL_DESC_DISPLAY_SIZE, SQL_COLUMN_LENGTH, and SQL_DESC_OCTET_LENGTH, the connector returns 0 for binary data types.

This issue has been resolved. SQL_DESC_DISPLAY_SIZE, SQL_COLUMN_LENGTH, and SQL_DESC_OCTET_LENGTH now returns with SQL_NO_TOTAL for binary data types. Note that SQL_DESC_LENGTH returns with 0.

  • [PGODBC-1297] In some cases, when multiple threads are creating and destroying the connection handle, the connector hangs or terminates unexpectedly.

  • [PGODBC-1314] When calling SQLExtendedFetch() and different sizes of SQL_ROWSET_SIZE is used, the connector returns incorrect data.

  • [PGODBC-1328] The ODBCMessages.xml file contains duplicate error keys.

  • [PGODBC-1330] When using Power Pivot to query the server, the connector returns a "Requested property not supported" error.

  • [PGODBC-1370] When querying SQLForeignKeys(NULL, 0, PKSchemaName, SQL_NTS, PKTableName, SQL_NTS, NULL, 0, FKSchemaName, SQL_NTS, NULL, 0) or SQLForeignKeys(NULL, 0, PKSchemaName, SQL_NTS, NULL, 0, NULL, 0, FKSchemaName, SQL_NTS, FKTableName, SQL_NTS), the connector returns an error.

  • [PGODBC-1370] When querying SQLForeignKeys(), the connector returns the result set in an incorrect order.

1.4.21 -----------------------------------------------------------------------

Released 2020-12-11

Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Driver 1.4.21.

  • [PGODBC-1297] In some cases, when multiple threads are creating and destroying the environment handle, the driver hangs or terminates unexpectedly.

  • [PGODBC-1304] When SQL_ATTR_AUTOCOMMIT is set to SQL_AUTOCOMMIT_OFF after the connection, the driver incorrectly returns a "current transaction is aborted, commands ignored until end of transaction block" error.

  • [PGODBC-1319] When SQL_ATTR_ACCESS_MODE is set to SQL_MODE_READ_ONLY before the connection, the driver log incorrectly shows "Failed to execute query before connecting to the server: SET readonly = true" where the query is not executed.

This issue has been resolved. The log now shows "Query is not executed because connection has not been established: SET readonly = true" in this case, and "Query executed: SET readonly = true" when the query is executed.

1.4.19 -----------------------------------------------------------------------

Released 2020-10-28

You can now configure logging for the current connection by setting the logging configuration properties in the DSN or in a connection string. For more information, see the Installation and Configuration Guide.

  • [PGODBC-1299] Updated third-party libraries

The driver has been updated to use the following libraries: - OpenSSL 1.1.1g (previously 1.1.1d) - ICU 58.3 (previously 58.2)

  • Additional operating system support

The driver now supports the following additional operating systems: - Windows Server 2019 - Red Hat Enterprise Linux (RHEL) 8 - CentOS 8 - SUSE Linux Enterprise Server (SLES) 15 - Ubuntu 18.04

  • [PGODBC-1233] Support for GEOMETRY data type

The driver now supports data of type GEOMETRY. For more information, see the Installation and Configuration Guide.

  • [PGODBC-1250] Updated TIME (WITH TIME ZONE) data type

Data of type TIME (WITH TIME ZONE) is now mapped to to SQL_TYPE_TIME for ODBC 3.0 or SQL_TIME for ODBC 2.0. For more information, see the Installation and Configuration Guide.

  • [PGODBC-1156] Support for read-only mode

You can now configure the driver to enable read-only mode. To do this, select the Enable Read Only check box (set the ReadOnly connection property to 1). For more information, see the Installation and Configuration Guide.

Additionally, you can change the read-only settings by setting SQL_ATTR_ACCESS_MODE to SQL_MODE_READ_WRITE or SQL_MODE_READ_ONLY.

Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Driver 1.4.18.

  • [PGODBC-1233] When using SQLParamData and SQLPutData to select and insert, the driver returns an error.

  • [PGODBC-1233] If autocommit is disabled and the query fails after execution, the driver returns a "current transaction is aborted, commands ignored until end of transaction block" error.

  • [PGODBC-1199] When using SQLSetDescRec() with SQL_TYPE_DATE and SQL_TYPE_TIMESTAMP, the driver returns an error.

  • [PGODBC-1275] When the connection object's destructor calls SQLDisconnect(), the driver terminates unexpectedly.

This issue has been resolved. When using the driver with an object that has static storage duration (such as a global), you may run into destruction order issues during application termination. The driver now returns SQL_ERROR when SQLDisconnect() is called in this case.

  • [PGODBC-1271] When using a column filter, SQLProcedureColumns() returns incorrect columns.

  • [PGODBC-1223] SQL_DATA_TYPE and SQL_DATETIME_SUB in SQLColumns return incorrect values for date and time data types.

This issue has been resolved. The driver now returns SQL_DATETIME for all date and time types in SQL_DATA_TYPE for SQLColumns. Additionally, the driver now returns SQL_CODE_DATE, SQL_CODE_TIME, or SQL_CODE_TIMESTAMP, depending on the type of date or time column, or null otherwise, in SQL_DATETIME_SUB for SQLColumns.

  • [PGODBC-1201] When using SQLPrimaryKeys with a schema name, the driver returns incorrect results.

The driver's implementation of SQLTables and SQLColumns has been updated to provide stronger protection against SQL injections.

  • [PGODBC-1154] Updated driver version information in Linux binary

You can now check the Linux driver's version from the driver binary file. To do this, open the .so file in a text editor, and search for the text "\(driver_version_sb\):". The driver's version number is listed after this text.

  • [PGODBC-1146] Updated OpenSSL library

The driver has been updated to use version 1.1.1d of the OpenSSL library.

Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Driver 1.4.10.

  • [PGODBC-1146] The driver terminates unexpectedly when both of the following occur:
  • Multiple database drivers are loaded to the same process.

  • One driver unloads and calls ICU's u_cleanup() function, while another driver continues to run and tries to access the memory space that has been cleaned up.

1.4.8 ------------------------------------------------------------------------

Released 2019-09-13

Enhancements & New Features

  • [PGODBC-1117] Updated third-party library linking for Linux

The Linux driver now statically links to the OpenSSL and ICU libraries by default. Driver builds with dynamically linked libraries continue to be available as needed. For more information about this change, contact Customer Support through https://www.simba.com/support/.

  • [PGODBC-1045] Oracle Linux support

The driver now supports Oracle Linux 7.5.

Resolved Issues The following issues have been resolved in Simba PostgreSQL ODBC Driver 1.4.8.

  • [PGODBC-1137] When an input parameter value is indicated as SQL_NULL_DATA during the SQLBindParameter call, the driver incorrectly binds the parameter using the SQL data type of the parameter specified in SQLBindParameter.
