PreparedStatement with Statement.RETURNGENERATEDKEYS. Statement.RETURNGENERATEDKEYS) For some JDBC drivers (for example, Oracle) you have to explicitly list.
-->The existence of a WfbUtilities class makes it possible that your ptmt2 variable refers to some subclass of PreparedStatement which is a wrapper for whatever MySQL returns. Perhaps the implementer of that subclass was lazy and didn't get around to implementing the getGeneratedKeys method. I'm using version 2.0.13 of mmmysql.The change log says Rudimentary version of Statement.getGeneratedKeys from JDBC-3.0 now implemented (you need to be using JDK-1.4 for this to work, I believe) I've previously found it works with java.sql.Statement but not with java.sql.PreparedStatement.

The Microsoft JDBC Driver for SQL Server supports the optional JDBC 3.0 APIs to retrieve automatically generated row identifiers. The main value of this feature is to provide a way to make IDENTITY values available to an application that is updating a database table without a requiring a query and a second round-trip to the server.
Bitcoin generate hd private key. Etc. There are well-turned private keys combinations in HEX and decimal (yes it is weird but it can be)For example: FFFFFFFFFFFF or. We use a dictionary attack to Brainwallet to cover the majority of easy generated wallets.A refers to the concept of storing Bitcoins in one's own mind by memorization of a passphrase. What we do is taking standard words and mix them to get the key and the address.
Java Preparedstatement Return Generated Keys
Because SQL Server doesn't support pseudo columns for identifiers, updates that have to use the auto-generated key feature must operate against a table that contains an IDENTITY column. SQL Server allows only a single IDENTITY column per table. The result set that is returned by getGeneratedKeys method of the SQLServerStatement class will have only one column, with the returned column name of GENERATED_KEYS. If generated keys are requested on a table that has no IDENTITY column, the JDBC driver will return a null result set.
As an example, create the following table in the sample database:
In the following example, an open connection to the sample database is passed in to the function, an SQL statement is constructed that will add data to the table, and then the statement is run and the IDENTITY column value is displayed.
