[bug-report]SQLRowCount set affected row numbers is incorrect when use SQLBindParameter and SQLSetStmtAttr for SQL_ATTR_PARAMSET_SIZE

Hi,

I'm tring to insert and update a lot of records using SQLBindParameter
and SQLSetStmtAttr, but SQLRowsCount returned record number affected by
ONLY the LAST SINGLE SQL STATEMENT.

Here is my code sequence.

1.
status = SQLBindParameter(cda,
KCPD_SCAST(KCPD_SQLUSMALLINT, parm_pos),
KCPD_SCAST(KCPD_SQLSMALLINT, param_type),
ftype,
KCPD_SCAST(KCPD_SQLSMALLINT, mapped_sqltype),
temp_column_size,
sqltype == SQL_TYPE_TIMESTAMP ? kcpd_odbc_date_scale : 0,
KCPD_RCAST(KCPD_SQLPOINTER, v.p_v),
buflen,
v.p_len);

2.
status = SQLSetStmtAttr(cda,
SQL_ATTR_PARAMSET_SIZE,
KCPD_RCAST(void*, temp_iters),
SQL_NTS);

3.
status = SQLExecute(cda);

4.
SQLRowCount(cda, affected_num);

I inserted 1000 records into the table, but affected_num set by
SQLRowCount is 1

I searched the source code for this issue, and found in CC_send_query_append
(connection.c:2062)

My question is :
Is this line (connection.cpp : 2062) has a bug? I think it may use '+='
rather than '='.
lack of libpg.dll and headers, I cannot compile the source code and check
my idea.
