Hi, guys! I use HDBC-ODBC module to work with windows data base and I got following problem: when I try to do INSERT

import Codec.Text.IConv (convert) import qualified Data.ByteString.Lazy as BSL ... let name = convert "UTF-8" "WINDOWS-1251" $ BSL.pack "bla" quickQuery "INSERT INTO Mytable (name,descript) VALUES (?, ?)" [toSql name), toSql name]

and this also not worked:

quickQuery "INSERT INTO Mytable (name,descript) VALUES (?, ?)" [toSql ( BS.pack "bla "), toSql ( BS.pack "blabla" )]

MSSQL server response me error: ... [ODBC SQL Server Driver][SQL Server]Invalid character value for cast specification It seems to be different encoding then HDBC-ODBC module can work with. I read documentation for HDBC:

To accomplish this, whenever a ByteString must be converted to or from a String, the ByteString is assumed to be in UTF-8 encoding, and will be decoded or encoded as appropriate. Database drivers will generally present text or string data they have received from the database as a SqlValue holding a ByteString, which fromSql will automatically convert to a String, and thus automatically decode UTF-8, when you need it. In the other direction, database drivers will generally convert a SqlString to a ByteString in UTF-8 encoding before passing it to the database engine.

How can I work with HDBC-ODBC module with non UTF-8 encoding? Cheers, Sergiy
