[DataDirect][ODBC SQL Server Native Wire Protocol driver][Microsoft SQL Server]Conversion failed when converting date and/or time from character string."
Error Message[DataDirect][ODBC SQL Server Native Wire Protocol driver][Microsoft SQL Server]Conversion failed when converting date and/or time from character string.
Defect NumberDefect DD00053392 / PSC00047189
Enhancement Number
Cause
The problem is caused by an application error. ODBC Test Unicode is sending UCS-2 string parameters to the driver when the C Type is SQL_C_CHAR. When the C Type is SQL_C_CHAR, the data should be in an ANSI character set and not UCS-2.  When UCS-2 is used for the character set of the data, the application should use the SQL_C_WCHAR data type.
Resolution
This is an application issue.
Workaround
Notes
Defect DD00053392 has been rejected as this is an application issue.
