Otherwise you will have to break it out into an INSERT/UPDATE operation. If you rely on MERGE in your current environment, be aware that you must be on v7.2.1 to use MERGE in Netezza. If you find that you rely on functions that exists in DB2 that you don't find natively in Netezza, be sure to check what is available in the SQL Extensions Toolkit, which is included with Netezza, but not automatically installed/configured. Stored procedures should avoid row-by-row/cusor-based processing when possible, as this is another case where you may prevent yourself from exploiting the parallel nature of the system. Avoid using ROW_NUMBER for this process as it will most often prevent you from exploiting the parallel nature of the system when used in this way.

On the topic of other issues you may face, here are a few thoughts:īe sure that you generate your surrogate keys either with Netezza's SEQUENCE object, or with a surrogate key generator in your ETL tool. A well-formed upsert process in ETL is a good way to manage for this. This bridge imports the database server metadata as multi models with one model per schema. Views, Stored Procedures)to produce the data flow lineage. Schemas, Tables, Columns, Data Types.) and parse any SQL (e.g.

Which is to say that they are purely informational (for bot the user and the optimizer). Netezza / Puredata SQL (Structured Query Language) In the continuing journey to track down impacted objects and to determine when the code in a database was last changed or added, here is another quick SQL, which can be used in Aginity Workbench for Netezza to retrieve a list of when Store Procedures were last updated or were created. This bridge uses a JDBC connection to a IBM Netezza database server to extract all its metadata (e.g.

Netezza does allow you to specify Primary Key and Foreign Key restraints, but they are not enforced.
