Hello,

We are using UTF-8 encoding and it is char that we are using! We aren't using 
wide APIs on Linux!

In the FreeTDS config file we are specifying the client charset as UTF-8.

Strange thing I observed was after commenting the following code the 
SQLExecDirect executes with SUCCESS.

         // Specify the number of elements in each parameter array.
         TRYODBC(hStmt, SQL_HANDLE_STMT, SQLSetStmtAttr(hStmt, 
SQL_ATTR_PARAMSET_SIZE, (SQLPOINTER)idCount, 0));

            // Specify an array in which to return the status of each set of
             // parameters.
            TRYODBC(hStmt, SQL_HANDLE_STMT, SQLSetStmtAttr(hStmt, 
SQL_ATTR_PARAM_STATUS_PTR, ParamStatusArray, idCount));

            // Specify an SQLUINTEGER value in which to return the number of 
sets of
          // parameters processed.
           TRYODBC(hStmt, SQL_HANDLE_STMT, SQLSetStmtAttr(hStmt, 
SQL_ATTR_PARAMS_PROCESSED_PTR, &ParamsProcessed, 0));


Also another point to notice is that, I have recently updated from 
freetds-0.91 and TDS version 7.1. The code worked seamlessly then!

Regards,
Manasi

I would first try with an easy query like "SELECT 1"

In which encoding the U_STRING store the string. No, Unicode is not enough 
(if you don't specify the version).

Should not be SQLExecDirectW or did you enabled UNICODE define in 
Makefile/project file(s) ?
