Hello,

I have a small application that first does a quick query to check 
something, then goes on to insert or update something based on the 
results of the first query.

However, the second query fails, without any errors from GetDiagRec, 
unless I call SQLFreeStmt with both SQL_CLOSE and SQL_RESET_PARAMS.

I ran SQL Profiler on the server, and saw that the actual query also 
changed. Normally the placeholders are replaced with variable names, 
but when not calling FreeStmt with SQL_RESET_PARAMS first, they show up 
as '?'.

Should I allways call FreeStmt with SQL_RESET_PARAMS before attempting 
to run a query using placeholders, or is this a bug somewhere?


Call sequence:
SQLPrepare(hstmt, "SELECT COUNT(x) ...", SQL_NTS);
SQLExecute();
SQLFetch();
SQLGetData();
SQLFreeStmt(hstmt, SQL_CLOSE);

SQLBindParameter
...
SQLPrepare(hstmt, "INSERT INTO x (a, b, c) VALUES (?, ?, ?)", SQL_NTS);
SQLExecute
SQLFreeStmt(hstmt, SQL_RESET_PARAMS);


Regards,
Frode
