Character conversion , command order

Hello Colleagues,

I have a MSSQL 2000 database and a system written in WinPROLOG (LPA;
unicode character coding) using it via ODBC. They are running with no
problem in Win XP (on common or different hardware). Now I try to
migrate the last one (the DB remains in WinXP) into the next
environment: Ubuntu 2.6.31-20 (English), Wine1.2 (1.1.40-0ubuntu1; XP),
unixodbc (2.2.11-16ubuntu1), freetds-0.82 (freetds-stable 2009.12.11).
The main settings:

/etc/odbcinst.ini:

[ODBC]
Trace		= yes
Tracefile	= /tmp/odbc.log
ForceTrace	= Yes
[mssql_tds]
Description	= MSSQL driver
Driver		= /usr/local/lib/libtdsodbc.so
Driver64		= 
Setup		= /usr/lib/odbc/libtdsS.so
Setup64		= 
UsageCount	= 2 
CPTimeout	= 
CPReuse		= 

/etc/odbc.ini:

[MSSQL]
Description	= mssql_tds
Driver		= mssql_tds
Server		= 192.168.1.65
Port		= 1433
Trace		= Yes
TraceFile	= /tmp/odbc.log

/usr/local/etc/freetds.conf (active lines)

[global]
	tds version = 8.0
	client charset = UTF-8
	dump file = /tmp/freetds.log
	dump file append = yes
	debug flags = 0xffff
	debug level = 10
	text size = 64512
[mssql_tds]
	host = 192.168.1.65
	port = 1433
	tds version = 8.0
	client charset = UTF-8

1) A slight problem: There is no freetds.log unless export
TDSDUMP=/tmp/freetds.log (start of Wine is complicated this way).

What to do to activate settings of freetds.conf?

2) The character conversion problem. On terminal I see:

hegedus@hegedus:~$ export TDSDUMP=/tmp/freetds.log 
hegedus@hegedus:~$ isql -v MSSQL user pw 
 <Connected! etc>
SQL> sp_databases 
 <list of databases including model>
SQLRowCount returns -1 
6 rows fetched 
SQL> use model 
[01000][unixODBC][FreeTDS][SQL Server]Changed database context to
'model'. 
[ISQL]INFO: SQLExecute returned SQL_SUCCESS_WITH_INFO 
SQLRowCount returns -1 
SQL> select * from jog 
+------------+---------------------------------+ 
| j_azon     | j_nev                           |

| 3          | | 
+------------+---------------------------------+ 
SQLRowCount returns 4 
4 rows fetched 
SQL> quit 
hegedus@hegedus:~$ 

In the freetdslog starts with:

iconv.c:197:names for ISO-8859-1: ISO-8859-1
iconv.c:197:names for UTF-8: UTF-8
iconv.c:197:names for UCS-2LE: UCS-2LE
iconv.c:197:names for UCS-2BE: UCS-2BE
iconv.c:363:iconv to convert client-side data to the "ISO-8859-1"
character set
iconv.c:516:tds_iconv_info_init: converting "ISO-8859-1"->"UCS-2LE"
iconv.c:516:tds_iconv_info_init: converting "ISO-8859-1"->"UCS-2LE"

The result of the select in the log is:

net.c:671:Received packet

0080 00                     -                        |.|

The ? in the only displayed name is instead of o-double-acute (not in
8859-1); the missing lines have characters existing in 8859-1 but not in
ASCI (the last one has 2 of them with o-double-acute). 

What to do to handle non-ASCI characters?

3) The mentioned programme uses procedure of MSSQL sp_databases, but –
as I see in the odbc.log – with different to isql set of ODBC commands.

The corresponding part of the odbc.log of isql is:

[ODBC][5053][SQLPrepare.c][189]
		Entry:            
			Statement = 0x80da110

			Character Attr = (nil)            
			Buffer Length = 0

[ODBC][5053][SQLColAttribute.c][648]

That of Prolog programme is:

[ODBC][4992][SQLBindCol.c][251]
		Exit:[SQL_ERROR]
		DIAG [S1003] [FreeTDS][SQL Server]Program type out of range

What can I do for this range (accepted by Windows-MSSQL2000 pair)?

Thank you
Gábor
