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
