Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
HCL OneDB™ ODBC Driver GuideThe HCL OneDB™ ODBC Driver Programmer's Manual serves as a user guide and reference for HCL OneDB™ ODBC Driver, which is the HCL OneDB™ implementation of the Microsoft™ Open Database Connectivity (ODBC) interface, Version 3.0.
Data typesThese topics contain information about the data types that are supported by HCL OneDB™ ODBC Driver.
Report standard ODBC typesHCL OneDB™ ODBC Driver supports existing applications that support standard ODBC data types only. Check the DSN option Report Standard ODBC Types to turn on this behavior.
Report wide character columnsHCL OneDB™ servers do not support wide character data types.

Report wide character columns

HCL OneDB™ servers do not support wide character data types.

When an application sets the Report Char Columns as Wide Char Columns option, the driver sets the following behavior:

SQLDescribeCol reports char columns as wide char columns
SQL_CHAR column is reported as SQL_WCHAR
SQL_VARCHAR column is reported as SQL_WVARCHAR
SQL_LONGVARCHAR column is reported as SQL_WLONGVARCHAR
The default is 0: (disabled)

After setting the Report Char Columns as Wide Char Columns option, calls to SQLBindParameter with SQL data types have the following behavior:

SQL_WCHAR is mapped to SQL_CHAR
SQL_WVARCHAR is mapped to SQL_VARCHAR
SQL_WLONGVARCHAR is mapped to SQL_LONGVARCHAR
