问题 Our Orchard CMS with multi-tenancy just went down. We have since brought it back online by restoring a version of the database, and then recycling the application pool. Communicating with the restored database continued to fail until we recycled the app pool. The post-mortem analysis of the error log from yesterday had zero errors, and the error log from today has about forty errors with the following pattern: About 20 SqlException errors reporting "invalid login" for two of the tenant

问题 This allows me to grab data from my database, store it as a DefaultTableModel and pass that model onto my GUI - populating my jTable with database data. This is the method within my Account class: public static DefaultTableModel buildTableModel() throws SQLException { Vector<Vector<Object>> data = new Vector<Vector<Object>>(); Vector columns = new Vector(); PreparedStatement ps = null; ResultSet rs = null; try { String stmt = "SELECT * FROM APP.DATAVAULT"; ps = Main.getPreparedStatement(stmt)

问题 We all know that SQLException is a checked Exception and most of us agree that checked Exception are verbose and leads to throw/catch pollution. Which approach should I choose to avoid SQLException throwing? Which wrapper/technique/library is recommended? (for example DataAccessException for the Spring folks, but I don't want to use Spring) 回答1: Just wrap it as new RuntimeException(jdbce) . Or defince your own exception that extends runtime exception and use it. I do not think that any

问题 I'm building an REST API and am working on returning the correct status codes to the client. I have a SQLite database and created one table like this: CREATE TABLE views(id INTEGER PRIMARY KEY AUTOINCREMENT, name varchar(10) UNIQUE NOT NULL, data varchar(10) NOT NULL) The connection to the database works fine. I am able to add a view entity to the table as well. When I run prepStmnt.execute() to add another view with the same name as the first one i get a SQLException as expected (since name

问题 I need to load data from an SQLite file into a java program which I develop in Netbeans. The file is to be loaded via a swing menu item. I'm using sqlitejdbc as driver. Here are the code blocks I assume to be important: // header stuff package aufgabe_9; import java.sql.*; //... // menu item opening the file private void mitemOpenFileActionPerformed(java.awt.event.ActionEvent evt) { /** * Handles the dialogue for selecting and loading file. */ JFileChooser fileChoose = new JFileChooser();

问题 I'm utilizing Java and SQLiteJDBC to work with SQLite. I need to access name of columns for a given table and I've found that I could accomplish this with the following command: pragma table_info(myTable) However, when attempting to do the following I get an error. PreparedStatement _pstmt = this._DBConnection.prepareStatement("pragma table_info( '?' );", new String[] {_tableName} ); java.sql.SQLException: NYI I have no idea what NYI means and furthermore, I'm not sure if I can do what I'm

问题 Last update After alot of testing, I realised that if i ran the same query over the same dataset (in this case a Northwind) table on SQL 2000 and SQL 2005, I get two different results. On SQL 2000, i get the error that's in the question. On SQL 2005, it succeeds. So I've concluded that the query generated by linqpad doesn't work on sql 2000. To reproduce this, run: OrderDetails .GroupBy(x=>x.ProductID) .Select(x=>new {product_id = x.Key, max_quantity = x.OrderByDescending(y=>y.UnitPrice)

问题 I'm developing a Webservice at the moment. I thought I was ready to release my first productive version but I keep getting a SQLException which doesn't make any sense to me. I'm developing against a Oracle db btw. Let me give you my code at first: try{ variable = DoQuery("SELECT KEY FROM TABLE WHERE KEY IN ('KEY1', 'KEY2') AND ROWNUM = 1").getString("HANDLE"); }catch(SQLException e){ return "Wasn't able to gather key: " + e.toString() + " - " + e.getSQLState(); } The method "DoQuery": private
