Editing JTable from RestulSet Table

问题:

Continuing this question.

My problem is that I can not edit my JTable. I get an exception and the Object value instead of what I should be seeing.

I am using the ResultSet Table code with a MS-Access database and with a few modifications. My code can be found here. I run into an error when I rs.updateRow() is called. java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]Error in row.

I did a google search on this error with updateRow() and not much came up. The only real answer I saw was to use a prepared statement but I am not a pro with SQL commands.

Also a plus if you could tell me the best approach in making this become a GlazedList so I can filter easily. Unless you can provide me something that filters regular JTables easily.

Trying to offer more help since the initial solution didn't work 100%.

Try the info here: Updatable ResultSets to see how to make your ResultSet updatable by specifying arguments when creating a Statement object from your Connection. I realized this option may not have been set by default for you. If you driver supports this mode, it should allow the code to work.

EDIT: It's not necessarily the driver (though you will need a JAR if you wish to change that). You need to enable ResultSet.TYPE_SCROLL_SENSITIVE when creating the table -- the driver may still support this mode. There are ways to probe what the JDBC driver supports, but they're kind of a pain to use unless you use a GUI like SquirrelSQL Client to get a full list of capabilities.

I am using the ResultSet Table code

Search the web for a better example of a ResultSetTableModel. I'm sure you will find one that already implements the setValueAt(...) method. Or another approach is to just copy the data from the ResultSet to a DefaultTableModel and then you can edit it no problem.

Unless you can provide me something that sorts regular JTables easily.

Have you read the JTable API and followed the link to the Swing tutorial on "How to Use Tables" which contains a working example of sorting, since sorting is a default part of the JDK.
