Oracle SQL MERGE Statement
https://www.databasestar.com/oracle-merge-sql/ In this video, we’ll learn what the Oracle MERGE statement does and how you can use it. What is the MERGE statement? It’s a statement that lets you either insert or update data in a table - all in a single statement! It’s helpful if you’re using an ETL (Extract Transform Load) process when creating or updating a data warehouse. It’s also helpful when loading data into your own database if you’re not creating a data warehouse. It allows you to prevent duplicate data and ensure you have up-to-date data in your table. The syntax looks like this: MERGE INTO table_name USING table_name ON (condition) WHEN MATCHED THEN update_clause DELETE where_clause WHEN NOT MATCHED THEN insert_clause [LOG ERRORS log_errors_clause reject_limit integer | unlimited ] In this video, I also show an Oracle SQL MERGE statement example, so watch the video to find out more. For more information on the MERGE statement and how you can use it in your queries, read the related article here: https://www.databasestar.com/oracle-merge-sql/

Main-Memory Join Algorithms: Sort or Hash?
The classical wisdom is that hashing is preferred method to implement joins in main memory. But this wisdom is now many years, if not decades, old and hardware has evolved considerably in the meantime. In this talk I will discuss join strategies for execution in main memory, including hash and sort-merge variants. The runtime characteristics of either strategy depends critically on a suitable implementation that respects the intricacies of modern hardware architectures. I will show how hash and sort-merge joins can be implemented to maximally benefit from hardware features like vector processing (SIMD), multi-level caches, multi-core parallelism, or NUMA-style memory arrangement. And I will point to pitfalls that could mis-guide conclusions about the �best� join implementation strategy. The join implementations discussed outperform the state of the art in join processing by several factors. Experiments on modern hardware platforms indicate that the sort-merge strategy is about to surpass hashing in upcoming hardware architectures�which might put classical wisdom upside-down.

SQL with Oracle 10g XE - Using SELECT and WHERE to Query a Table
In this video I use the SELECT command to query information from my table. Rather than viewing the entire table I can select which columns I want to see as well as in which order I would like them to appear. I use the WHERE command to state a condition on the query that will result in narrowing my search. This video is part of a series of videos with the purpose of learning the SQL language.

When to use Oracle Database Bitmap Indexes Lesson 1
This tutorial will identify some use cases for Oracle bitmap indexes, including some of the more advanced capabilities. See all lessons, free, at http://www.skillbuilders.com/when-to-use-oracle-bitmap-indexes. Indexing your Oracle Database for best performance? There are cases, depending on data structures and queries, where b-tree indexes are not useful (e.g. scan access paths perform inadequately). In these cases, bitmap indexes may be a better solution. Bitmap indexes are a powerful tool, but they need to be used with care. Inappropriate use may cause problems worse than those they solve. The tutorial covers somewhat more advanced cases such as using bitmap join indexes to denormalize a snowflake schema, and to enable star transformations in queries that join fact tables to several dimension tables. This training will benefit any Oracle DBA administering a Data Warehouse or VLDB and "power" developers working in same. Instructor: Oracle Certified Master DBA John Watson, SkillBuilders
