Sorry, looks like my former post is missing:

 

Hi,

            When using the ODBC driver of FreeTDS, the query will time
out if the query was sent by a statement used before. The code was like:

------------------------------------------------------------------------
------------------------------------------------------------------------
---------------------------

            SQLSetStmtAttr (hstmt, SQL_ATTR_QUERY_TIMEOUT,  (SQLPOINTER)
40, SQL_IS_UINTEGER);

            SQLPrepare(hstmt, "...");

            SQLExecute(hstmt);

            // fetch the data

 

            // Wait for 3 minutes

            SQLFreeStmt(hstmt, SQL_CLOSE);

            SQLFreeStmt(hstmt, SQL_UNBIND);

            SQLFreeStmt(hstmt, SQL_RESET_PARAMS);

            SQLCloseCursor(hstmt);

            

            SQLSetStmtAttr (hstmt, SQL_ATTR_QUERY_TIMEOUT,  (SQLPOINTER)
40, SQL_IS_UINTEGER);

            SQLPrepare(hstmt, "...");

            SQLExecute(hstmt); // here I got a timeout.

------------------------------------------------------------------------
------------------------------------------------------------------------
---------------------------

 

            It looks to me the tds->query_start_time inside the hstmt
was not cleaned up correctly. (Actually the value is the old time for
the first query) This data member looks like a new one to me. (I am
still using the a FreeTDS version from 2004 and only recently updated to
the 0.64 stable)

 

            For now I will just create a new statement handle for each
new query, but I would like to know whether it is a bug or just I am
writing the wrong code.
