As discussed before, the benefit to this is that it potentially eliminates 3 separate batches (UPDATE, INSERT, AND DELETE ) and puts them into one batch helping to minimize locking and increase efficiency. Use the DDL operator to send the INSERT /SELECT request to move the data from the staging table to the destination table. Concurrent Loading into Multiple Tables Use the Update operator to perform INSERT, UPDATE, and DELETE operations on multiple tables. The Inserter operator can insert CLOB and BLOB data types into a Teradata table The Selector operator can export CLOB and BLOB data types from a Teradata table The Data Connector operator can read/write CLOB and BLOB data types from/to a file. Mini-Batch Loading If the Teradata table is already populated or has secondary or join indexes, Teradata recommends mini-batch loading, which requires 2 steps: Use the Load operator to load data into an empty Teradata staging table.
Another inappropriate use of merge is on code that is mission critical that may need to be troubleshot very quickly. Unfortunately merge does not provide very good insight into what rows have been updated versus inserted or deleted.
We are also going to delete the records in the target that do not exist in the source. cc langsql MERGE dbo. TargetTable tgt Target Table USING urceTable src Source Table ON Main Comparison WHEN NOT MATCHED BY TARGET IDs from Source do not exist in Target THEN INSERT Insert records from source ( ID, Name. The Update operator supports up to 5 tables. For more than 5 tables, use the Stream operator. It supports up to 127 tables. Continuous Loading of Transactional Data from JMS, MQ, or Named Pipe. Both tables involved in the transaction will receive benefit. If the data in one table needs to be synchronized with the other, then you can do so without having to take the target table offline or performing two separate batches and wrapping them in a transaction. The Stream, Inserter, and Selector operators do not use a load slot. They use the Teradata SQL protocol. Selecting the wrong operator could delay the execution of the job. Data Availability Critical mission data needs to be loaded in near real-time. We could have also performed the same action using LECT cc langsql INSERT INTO dbo. TargetTable ( ID, Name ) SELECT ID, Name FROM urceTable src WHERE NOT EXISTS (SELECT 1 FROM dbo. If youre like me, the minute you get to develop a new application using 2008 you decide to use every new feature introduced. Well, while you learn everything up front, you also make more mistakes up front. Use the FastLoad INMOD Adapter operator to interface with a FastLoad INMOD routine. Use the MultiLoad INMOD Adapter operator to interface with a MultiLoad or TPump INMOD routine. Use the FastExport OUTMOD Adapter operator to interface with a FastExport OUTMOD routine. Another difficulty in troubleshooting is not only finding out which records have been updated or inserted, but how many records were updated versus how many were inserted. There is a way to do this, however its not pretty.
