Enable query logging in SQL Server - c++11

Question

ALL,
I'm trying to execute following code:
SQLHSTMT stmt = 0;
SQLHDBC hdbc;
SQLLEN cbName, cbTableName = SQL_NTS, cbSchemaName = SQL_NTS;
long id;
int result = 0;
std::wstring query;
SQLWCHAR *qry = NULL, *tname = NULL, *sname = NULL;;
if( pimpl->m_subtype == L"Microsoft SQL Server" || pimpl->m_subtype == L"Sybase" || pimpl->m_subtype == L"ASE" )
query = L"SELECT object_id FROM sys.objects o, sys.schemas s WHERE s.schema_id = o.schema_id AND o.name = ? AND s.name = ?;";
qry = new SQLWCHAR[query.length() + 2];
tname = new SQLWCHAR[tableName.length() + 2];
sname = new SQLWCHAR[schemaName.length() + 2];
memset( tname, '\0', tableName.length() + 2 );
memset( sname, '\0', schemaName.length() + 2);
uc_to_str_cpy( sname, schemaName );
uc_to_str_cpy( tname, tableName );
memset( qry, '\0', query.length() + 2 );
uc_to_str_cpy( qry, query );
SQLRETURN retcode = SQLAllocHandle( SQL_HANDLE_DBC, m_env, &hdbc );
SQLSMALLINT OutConnStrLen;
retcode = SQLDriverConnect( hdbc, NULL, m_connectString, SQL_NTS, NULL, 0, &OutConnStrLen, SQL_DRIVER_NOPROMPT );
auto dbName = new SQLWCHAR[pimpl->m_dbName.length() + 2];
memset( dbName, '\0', pimpl->m_dbName.length() + 2 );
uc_to_str_cpy( dbName, pimpl->m_dbName );
retcode = SQLSetConnectAttr( hdbc, SQL_ATTR_CURRENT_CATALOG, dbName, SQL_NTS );
delete[] dbName;
dbName = nullptr;
retcode = SQLAllocHandle( SQL_HANDLE_STMT, hdbc, &stmt );
retcode = SQLPrepare( stmt, qry, SQL_NTS );
SQLSMALLINT dataType[2], decimalDigit[2], nullable[2];
SQLULEN parameterSize[2];
retcode = SQLDescribeParam( stmt, 1, &dataType[0], &parameterSize[0], &decimalDigit[0], &nullable[0] );
retcode = SQLBindParameter( stmt, 1, SQL_PARAM_INPUT, SQL_C_DEFAULT, dataType[0], parameterSize[0], decimalDigit[0], tname, 0, &cbTableName );
retcode = SQLDescribeParam( stmt, 2, &dataType[1], &parameterSize[1], &decimalDigit[1], &nullable[1] );
retcode = SQLBindParameter( stmt, 2, SQL_PARAM_INPUT, SQL_C_DEFAULT, dataType[1], parameterSize[1], decimalDigit[1], sname, 0, &cbSchemaName );
retcode = SQLExecute( stmt );
retcode = SQLBindCol( stmt, 1, SQL_C_SLONG, &id, 100, &cbName );
retcode = SQLFetch( stmt );
if( retcode != SQL_SUCCESS && retcode != SQL_SUCCESS_WITH_INFO && retcode != SQL_NO_DATA )
{
GetErrorMessage( errorMsg, 1, stmt );
result = 1;
}
else if( retcode == SQL_NO_DATA )
tableId = 0;
delete[] qry;
qry = NULL;
delete[] tname;
tname = NULL;
delete[] sname;
sname = NULL;
(error checking is omitted for clarity)
When executing, everything is succeeded, except SQLFetch() which doesn't return any rows and therefore tableId will be 0.
The weird thing is - running the query in the SQL Server Studio succeeds and the row is returned.
Can someone please explain how is it possible?
Or better yet - explain to me how can I get the exact query executed on the server to be logged.
Because trying to do Server -> Management -> SQL Logs and choosing a "Current Log" I can only see queries that are crashing..
TIA!!
And yes - I'm using 2008 SQL Server for testing purposes.
