1.Introduction to basic SQL*Plus and SQL commands in oracle 9i
 
20:41
A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. Many popular databases currently in use are based on the relational database model.RDBMSs have become a predominant choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data, and much more since the 1980s. Relational databases have often replaced legacy hierarchical databases and network databases because they are easier to understand and use. However, relational databases have been challenged by object databases, which were introduced in an attempt to address the object-relational impedance mismatch in relational database, and XML databases. Object-relational database management system (ORDBMS) ============================================ An object-relational database can be said to provide a middle ground between relational databases and object-oriented databases (OODBMS). In object-relational databases, the approach is essentially that of relational databases: the data resides in the database and is manipulated collectively with queries in a query language; at the other extreme are OODBMSes in which the database is essentially a persistent object store for software written in an object-oriented programming language, with a programming API for storing and retrieving objects, and little or no specific support for querying. Object-relational database management systems grew out of research that occurred in the early 1990s. That research extended existing relational database concepts by adding object concepts. The researchers aimed to retain a declarative query-language based on predicate calculus as a central component of the architecture. Probably the most notable research project, Postgres (UC Berkeley), spawned two products tracing their lineage to that research: Illustra and PostgreSQL. Many of the ideas of early object-relational database efforts have largely become incorporated into SQL:1999 via structured types. In fact, any product that adheres to the object-oriented aspects of SQL:1999 could be described as an object-relational database management product. For example, IBM's DB2, Oracle database, and Microsoft SQL Server, make claims to support this technology and do so with varying degrees of success. SQL(Structures Query Language) ======================== SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.The acronym SEQUEL was later changed to SQL because "SEQUEL" was a trademark of the UK-based Hawker Siddeley aircraft company. SQL*Plus ======= SQL*Plus is a command line SQL and PL/SQL language interface and reporting tool that ships with the Oracle Database Client and Server software. It can be used interactively or driven from scripts. SQL*Plus is frequently used by DBAs and Developers to interact with the Oracle database. If you are familiar with other databases, sqlplus is equivalent to: "sql" in Ingres, "isql" in Sybase and SQL Server, "sqlcmd" in Microsoft SQL Server, "db2" in IBM DB2, "psql" in PostgreSQL, and "mysql" in MySQL.

Top Nine Coding Guidelines for Oracle PL/SQL
 
08:00
My take, as of November 2015, of some of the most helpful guidelines to follow when writing PL/SQL code: 1. MAXSQL - maximize use of SQL first and foremost 2. SPOD - single point of definition 3. TRACE - production-available application-level tracing 4. LOG - consistent, encapsulated error logging 5. BULK - avoid row by row 6. OBVIOUS - make your code tell its own story, comment when it can't 7. NESTPROG - use nested subprograms 8. DECLARE - use declarative features of language 9. WARN - use compile-time warnings Accompanying blog post: http://stevenfeuersteinonplsql.blogspot.com/2015/10/your-ideas-for-more-important-plsql.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

Working with the Trace File Analyzer Collector
 
28:22
The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command. Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface Copyright © 2014 Oracle and/or its affiliates.

Tracing: Transaction ST12 = Combination of two transactions . SAT (ABAP Trace) , ST05 = SQL Trace SQL Trace: To monitor the database access of reports and transactions. Less common traces : Enqueue Trace: (the locking system),RFC Trace, Table buffer trace: Performance Improvements ABAP Coding: Keep an eye on those loops. Select statements in loops = absolutely avoid = use for all entries instead Function call, or performs in loops = re - visit and see if you can optimize The "READ TABLE" statement Sorted table- Binary search .. Or even better use "Index" on internal tables. Use mass operations on internal table = internal table copy one to another, Append lines of int_fligh1 to int_fligh2. Use field symbols to modify internal table in a loop (minor improvement ) A little trick if you call performs in a loop:: Use static variables Avoid sleep, wait etc commands.. Or synchronous RFC calls 2)Database bottleneck Use Indexes : Make sure Indexes are being used in your select statement (check with trace if needed) Extreme case , create new index (this has the disadvantage of making the insert slower) Select -- End select loop : Usually database optimiser will fix it, still avoid it Select * into corresponding fields = about a millisecond slower Make clever use of inner joins Use views Use (max,min, avg): example : Select max( flightnum ) from flight . GET RUN TIME command Reduce I/O first, then memory, then CPU activity.Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory)

Oracle SQL Performance Tuning for Developers: Understand Explain Plans
 
01:42
Understanding Explain Plans is an excerpt from Oracle SQL Performance Tuning for Developers: http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027 6+ Hours of Video Instruction The focus of Oracle SQL Performance Tuning for Developers LiveLessons is to illustrate coding techniques that ensure a consistent response time between instances and releases of the Oracle database. This course works closely with performance tuning of actual SQL statements. Description In this video training, Dan Hotka starts out with a complete overview of the Oracle architecture so students can get an understanding how their SQL and applications can take advantage of the computing environment. This course then goes in-depth on understanding and controlling the Explain Plan, which is how and in what order Oracle retrieves data. The discussion includes considerable detail, with SQL examples, on how the optimizers--both rule-based and cost-based, but mostly cost-based--make their decisions. Students will work with a variety of SQL statements, reviewing Explain Plans and making changes to make these SQL statements perform better. Lectures include index design, using hints and coding style to control the Explain Plans, and how to use useful tools such as index monitoring, SQL Trace, and the PL/SQL profiler. This LiveLessons course takes a close look at indexes: how Oracle selects them, why they are sometimes not used, and how to tell if indexes are being used. This course includes Oracle10g, Oracle11g, and Oracle12c SQL tuning topics. Skill Level Intermediate Learn How To Read and understand Explain Plan content Review an Explain Plan and tell quickly if this is a good plan Understand a good index column candidate from a not-so-good candidate Quickly tell the likelihood if your SQL will use an existing index Use coding and a variety of Hints (directives) that can produce better performing SQL Execute and interpret SQL trace output Who Should Take This Course Oracle programmers Oracle database administrators who need additional training on SQL tuning Course Requirements Working knowledge of the SQL query language http://www.informit.com/store/oracle-sql-performance-tuning-for-developers-livelessons-9780134117027

Oracle SQL MERGE Statement
 
07:52
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/
