I am trying to currently connect to a database on my current computer. import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class Main { public static void main(String[] argv) throws Exception { Connection connection = null; try { // Load the JDBC driver String driverName = "oracle.jdbc.driver.OracleDriver"; Class.forName(driverName); // Create a connection to the database String serverName = "localhost"; String portNumber = "1521"; String sid = "xe"; String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid; String username =

I've got a logger that records exception information for our in house applications. When we log SQL exceptions it'd be super useful if we could see the actual query that caused the exception. Is there a way we can achieve this? The SqlException does not hold a reference to the SqlCommand that caused the exception. In your logger there is no way to do this. What you could do is catch the SqlException in the method that executes the SqlCommand and wrap it in a more descriptive exception. Example: using (var command = new SqlCommand(connection, "dbo.MyProc")) { try { command.Execute(); } catch

I want to handle different problems, while doing database operations, differently. e.g. The operation may fail because of wrong database credentials or due to network problem. Or it may fail because the query is not correct (if string value is being passed in the int type column) In my C# code, we only have SqlException which has collection of SqlErrors . However there are many severity levels. How can i easily identify the cause of the SqlException ? How can i determine the exception is because of the connectivity problem or authentication failure or because of the problem with the query. I

the last days I was trying to learn how to access mySQL databases via Java. I am able to load the driver and get a connection to the database ( at least I think so, since I don't get an exception there..) the code is: import java.sql.*; public class test { public static void main(String[] args) { try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); System.out.println("driver loaded..."); } catch(ClassNotFoundException e){ System.out.println("Error in loading the driver..."+e); System.exit(0); } try { Connection dbConnection= DriverManager.getConnection("jdbc:odbc:test","root","password");
