Hai All, I am stuck up with a problem, rather, an SQL Exception.Anyone helping out me is appreciated. I fetch some values from Dbase using Stored Procedures which I call thro'my EJBean. I have declared Cursors in my procedures which actually contains the SQL Queries. I am very much successful in getting the values . But,Once I refresh the page which ... |
Jade The last time I got an InvalidCursor state error it was because I had tried to get a value from a resultSet and hadn't called next() on it to get to the first record. It could be that or your at th end of the result set and trying to access a value. hope that helps |
|
Thanks for your response. I have identified the source of error. Unfortunately i don't have the solution. I'm facing this problem when i have more than 10 records in the db table. The reason could be that when u traverse through the resultset after 10 rows it refreshes it and hence throws the error. Thanks In Advance. Nijeesh. |
|
This isn't an immediate answer, unfortunately, but. . . try chaining through your SQLException to see if you can find a more descriptive problem buried in the exception trail. Do something like. . . catch (SQLException e) { // print out info on e . . . // now. . . SQLException nextException = e.getNextException(); while (nextException != null) { // ... |

Hi Venkat, I dont really know what do to in oracle for this type of error, but i am using MySql4.0 and in my client, i can see some variables like Table_locks_waited,Table_locks_immediate, wait_timeout. May be you should try to find corressponding variables to set, so that your query waits for certain time to get back the results. |

There's a few other basic items that you could check: -TCP/IP connections are disabled by default -check all port numbers are the same -confirm that the SQL Server is actually running -double check user names and passwords. You could check that SQL Server is set to mixed authentication. The driver from Microsoft can not handle Windows integrated authentication (there's third party ... |

Well for starts, the stack trace indicates the problem is with your getConnection() line so everything after that is irrelevant.

[URL=For example, the method getInt can be used to retrieve any of the numeric or character types.

Hmmm, probably JDBC driver specific. Is there no driver generated error code further down the stack trace ? I /think/ I've had such a response when there was no data available (but not because of an empty result set). Thus, I suspect a programming/configuration error (as opposed to an SQL error). Check that you've a valid connection, that the statement is ... |

Hi, I guess it depends on the technology you use to access your database (JDBC, O/R mapping etc.) what kind of information you will get in case of a constraint violation.

A word of honest advice: If you don't understand much of Java, and specifically, if you don't understand how checked exceptions work, you're in over your head looking at JDBC.

That is a configuration problem in your MySQL DB. Read the MySQL manual, concentrating on the "GRANT" statement and user privileges.
