When connected to a Unicode database, the Sybase Wire Protocol driver supports Unicode data types listed in the following table, in addition to standard ODBC data types listed in Data Types.
1 This data type is available only if the data source is configured to use the UTF-8 character set.
2 This data type is available only if the data source is configured to use the UTF-8 character set.
3 This data type is available only if the data source is configured to use the UTF-8 character set.
4 On Sybase 12.5 servers, this data type is available only if the data source is configured to use the UTF-8 character set. On Sybase 12.5.1 and higher servers, this data type is always available, even if the data source is not configured to use the UTF-8 character set.
5 This data type is available on Sybase 15 and higher servers only.
6 On Sybase 12.5 servers, this data type is available only if the data source is configured to use the UTF-8 character set. On Sybase 12.5.1 and higher servers, this data type is always available, even if the data source is not configured to use the UTF-8 character set.
7 This data type is available only if the data source is configured to use the UTF-8 character set.
For data types that require the UTF-8 character set, set the Charset connection string attribute. See Charset for information about using this connection string attribute.
The driver supports the Unicode ODBC W (Wide) function calls, such as SQLConnectW. This allows the Driver Manager to transmit these calls directly to the driver. Otherwise, the Driver Manager would incur the additional overhead of converting the W calls to ANSI function calls, and vice versa.
See UTF-16 Applications on UNIX and Linux for related details. Also, refer to "Internationalization, Localization, and Unicode" in the DataDirect Connect Series for ODBC Reference for a more detailed explanation of Unicode.
