Subject [jira] Created: (DERBY-149) Server hang when invalid string is bound to datetime columns.

Server hang when invalid string is bound to datetime columns.
-------------------------------------------------------------

         Key: DERBY-149
         URL: http://issues.apache.org/jira/browse/DERBY-149
     Project: Derby
        Type: Bug
  Components: Network Server  
 Environment: Derby running with Network Server via JDBC universal driver.
    Reporter: A B


When running against Derby Network Server with the JCC driver, attempts to bind an invalid
date/time string to a date/time/timestamp parameter lead to a hang in the client program.

The problem does NOT occur if the same thing is run against a DB2 server, which suggests the
bug is in Network Server, not in the JCC driver.  That said, though, the problem also does
NOT happen if one uses an ODBC client to connect to Network Server, instead of a JDBC client--so
perhaps it's a problem with JCC, after all...hard to say one way or the other...

Here's a simple program to reproduce the problem:

import java.sql.*;

public class go {

	public static void main (String[] args) throws Exception {

		Class.forName("com.ibm.db2.jcc.DB2Driver");
		Connection c = DriverManager.getConnection(
			"jdbc:derby:net://localhost:1527/ugh;create=true", "bah", "humbug");

		Statement s = c.createStatement();
		try {
			s.execute("drop table dt");
		} catch (SQLException se) {}

		s.execute("create table dt (d date)");
		PreparedStatement pSt = c.prepareStatement("insert into dt values (?)");

		try {
			pSt.setString(1, "oops"); // invalid date value.
			pSt.execute();
		} catch (SQLException se) {
			System.out.println("Got " + se.getSQLState() + ": " + se.getMessage());
		}
	}

}

Of course, in order for the program to run, one must start the Network Server on port 1527
first.
