Does Qt 4.4.0's TDS Engine support transaction and storage procedure's call

Does Qt 4.4.0's TDS Engine support transaction and storage procedure's
call. There is output parameter and returned recordset in the storage
procedure.

for examples:
SQL Script:

----------------------
declare @aaa float
set @aaa = 10.0
exec proc1 @aaa output
-----------------------

----------------------
declare @aaa float
set @aaa = 10.0
exec proc1 @aaa output
-----------------------

To copy to clipboard, switch view to plain text mode 

Qt Code:

-----------------------
QSqlQuery q;
q.prepare("exec proc1 ?");
q.bindValue(0, 0, QSql::Out);
q.exec();
double f = q.boundValue(0).toDouble();    // fetch the output parameter
 
 
------------------------

-----------------------
QSqlQuery q;
q.prepare("exec proc1 ?");
q.bindValue(0, 0, QSql::Out);
q.exec();
double f = q.boundValue(0).toDouble();    // fetch the output parameter

stored procedure returned values and and recordsets are not fully supported, as the documentation states.

what driver and what dbms are you using?

Thanks for edited.


Qt 4.3.1's tds (connect mssql by db-library(ntwdblib.dll)) is not support transaction and store procedure's out params or returned recordsets.
I want to know the tds(mssql/ntwdblib.dll) of Qt 4.4.0's information about transaction and store procedure's out params.
