pilot没法改数据

[faucet]

用jbuilder的database pilot用odbc:jdbc接sqlserver2000，修改数据
提示
----------------------------------------------------------
DataSet has no unique row identifiers.
Note: For QueryDataSets you need to disable metaDataUpdate.ROWID in the
MetaDataUpdate property, in addition to setting the RowId property on a column.
----------------------------------------------------------
用org.gjt.mm.mysql.Driver接mysql，改数据提示
----------------------------------------------------------
The row specified by the resolution query was not found.
Typical reasons are:
Somebody deleted or changed this row.
A floating point comparison failed to match.
A CHAR field needs space padding (see Database.setUseSpacePadding).
Query:


Query:
UPDATE area SET title = ? WHERE id = ? AND title = ?

Row values used for finding existing row:
id=1:title=杭州市
----------------------------------------------------------

数据库没有动过，前几天还好的

还有一个问题

用sqlserver的jdbc驱动（m$提供的）接sqlserver20000时unicode的字段正常,
gb2312的乱码，如何解决？
