When you have to generate a primary key based on the existing primary keys, unless the new primary key is simple to generate by adding one to the maximum, there is no direct way to do it in Kettle. In general, for best practices reasons, this is not an advisable solution. This strategy for performing inserts and updates has been proven to be much faster than the use of the Insert/Update step whenever the ratio of updates to inserts is low. Those that already existed would be duplicated instead of updated. The Table Output would insert all the rows. If the columns in the Key field's grid of the Insert/Update step are not a unique key in the database, this alternative approach doesn't work.

The rows for which the insert fails go to the Update step, and the rows are updated. In this case, Kettle tries to insert all records coming to the Table Output step. Finally, fill the lower grid with those fields that you want to update, that is, those rows that had Y under the Update column.

In the Update step, select the same table and fill the upper grid-let's call it the Key fields grid-just as you filled the key fields grid in the Insert/Update step. In the Table Output select the table employees, check the Specify database fields option, and fill the Database fields tab just as you filled the lower grid in the Insert/Update step, excepting that here there is no Update column.

In order to find the values for these settings, you will have to refer to the driver documentation. In the Settings frame specify the connection string (which should be explained along with JDBC), the driver class name, and the username and password. In this case, as connection type choose Generic database. Copy the jar file containing the driver to the libext/JDBC directory inside the Kettle installation directory. First of all, you have to get a JDBC driver for that DBMS. In that case, you might still create a connection to that database. However, it can happen that you want to connect to a database that is not in that list. The list includes both commercial databases (such as Oracle ) and open source (such as PostgreSQL ), traditional row-oriented databases (such as MS SQL Server ) and modern column-oriented databases (such as Infobright ), disk-storage based databases (such as Informix ) and in-memory databases (such as HSQLDB). Kettle offers built-in support for a vast set of database engines.
