Oracle vs. SQL Server Why Oracle wins.Here is a brief comparison between Oracle 9i and SQL Server 2.In my view, Oracle comes out ahead in this c.By submitting your personal information, you agree that Tech.Target and its partners may contact you regarding relevant content, products and special offers.You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy.Platform dependency.SQL Server is only operable on the Windows platform, a major limitation for it to be an enterprise solution.E13167_01/aldsp/docs25/samples_tutorial/wwimages/figure19-14.gif' alt='Oracle Update Inner Join Syntax In Oracle' title='Oracle Update Inner Join Syntax In Oracle' />Oracle is available on multiple platforms such as Windows, all flavors of Unix from vendors such as IBM, Sun, Digital, HP, Sequent, etc.VAX VMS, as well as MVS.The multi platform nature of Oracle makes it a true enterprise solution.Locking and concurrency.SQL Server has no multi version consistency model, which means that writers block readers and readers block writers to ensure data integrity.In contrast, with Oracle, the rule is readers dont block writers and writers dont block readers.This is possible without compromising data integrity because Oracle will dynamically re create a read consistent image for a reader of any requested data that has been changed but not yet committed.In other words, the reader will see the data as it was before the writer began changing it until the writer commits.SQL Servers locking scheme is much simpler less mature and will result in a lot of delayswaits in a heavy OLTP environment.Also, SQL Server will escalate row locks to page level locks when too many rows on a page are locked.This locks rows which are uninvolved in any updates for no good reason.Performance and tuning.In SQL Server, the DBA has no real control over sorting and cache memory allocation.The memory allocation is decided only globally in the server properties memory folder, and that applies for ALL memory and not CACHING, SORTING, etc.All pages blocks are always 8k and all extents are always 8 pages 6.This means you have no way to specify larger extents to ensure contiguous space for large objects.ANSI+Joins+ANSI+defined+join+syntax+in+ANSI+SQL2+Standard+%281992%29.jpg' alt='Oracle Update Inner Join Syntax In Oracle' title='Oracle Update Inner Join Syntax In Oracle' />No range partioning of large tables and indexes.In Oracle, a large 1.GB table can be seamlessly partitioned at the database level into range partitions.For example, an invoice table can be partitioned into monthly partitions.Such partitioned tables and partitioned indexes give performance and maintenance benefits and are transparent to the application.There is no partitioning in SQL Server.There are no bitmap indexes in SQL Server.There are no reverse key indexes in SQL Server.There are no function based indexes in SQL Server.There is no star query optimization in SQL Server.Object types. Here are some object types missing in SQL Server that exist in Oracle.You cannot declare public or private synonyms.Update Using Inner Join in SQL Server.Using the same concept of Inner join, we can update rows in one table based on another table using Inner Join.Purpose. Use a SELECT statement or subquery to retrieve data from one or more tables, object tables, views, object views, or materialized views.If part or all of the.Free Oracle Magazine Subscriptions and Oracle White Papers Oracle Joins Version 11.Demo Tables Data Join Demo Tables CREATE TABLE person.In this post Ill show you how to do all the main types of Joins with clear SQL examples.The examples are written for Microsoft SQL Server, but very similar syntax.W2KKAfhggcA/hqdefault.jpg' alt='Oracle Update Inner Join Syntax In Oracle' title='Oracle Update Inner Join Syntax In Oracle' />There is no such thing as independent sequence objects.There are no packages i.No before event triggers only after event triggers and no row triggers only statement. Free Pdf To Microsoft Word Conversion . No object types like in PLSQL.PLSQL versus T SQLIn T SQL there are significant extensions to the ANSI SQL 9.The INNER JOIN, LEFT OUTER, RIGHT OUTER JOIN syntax differs from the classic JOIN.No Java database engine as in Oracle.Stored procedures in SQL Server are not compiled until executed which means overhead, late binding and finding errors at execution time only.No ability to readwrite from external files from a stored procedure.PLSQL has many DBMS system packages, where T SQL relies only on a limited number of extended and system stored procedures in the master database.PLSQL is better in error exception handling, and there is no such thing as exceptions in T SQL T SQL uses error not elegant.T SQL does not have the MINUS operator, that makes finding schema differences more difficult in SQL Server.In SQL Server there is no dead connection detection.Clients who lose their connection may still hold locks until a DBA is notified to kill their server side processes.In SQL Server there is no such thing as SQLNET aliasesservice namesThis means applications have to hard code the actual server name into their apps, making it difficult to move databases later to load balance across servers.Clustering technology.In clustering technology, Oracle is light years ahead, since SQL Server has nothing like Oracle Parallel ServerRAC two instances acting on the same data in active active configurations.And with the new version of Parallel Server in Oracle 9i, renamed as the Oracle Real Application Clusters, there is diskless contention handling of read read, read write, write read, and write write contention between the instances.This diskless contention handling is called Cache Fusion, and it means for the first time, any application can be placed in a cluster without any changes, and it scales upwards by just adding another machine to the cluster.Microsoft has nothing like this.Reliability. In SQL Server Standard Edition there is no ability to mirror the transaction log files.In Enterprise Edition there is a log shipping process that is not so reliable.If the logs fill up the disk, the database will crash hard.Sometimes this requires the server itself to be rebooted.Summary. SQL Server is clearly positioned between Microsoft Access and Oracle in terms of functionality, performance and scalability.It is a good workgroup level solution, a very quick time to market solution, and is very simple to use and administer.Oracle is much more advanced and has more to offer for larger applications with both OLTP and data warehouse applications.Its new clustering features are ideal for Application Service Providers ASPs on the Internet, who can now start with a cluster of two small servers and grow by just adding a server when they need to.Reader Feedback. Lucy L.I have worked with both and mostly agree with the authors observations, but I would like to mention the other side of this comment No before event triggers only after event triggers and no row triggers only statement.In SQL server, the statement level trigger gives you access to the pseudo tables INSERTED and DELETED.This means you can perform an action for each row operated on in a setwise fashion rather than in the row at a time fashion you must use in Oracle.This is a much better deal in bulk operations where an Oracle row level trigger can eat up much of the performance advantage of bulk inserts or updates.Balaji S. writes I think it is fundamentally wrong to compare SQL Server with Oracle.I agree with all the points mentioned in the article.Oracle is a more mature and advanced product than SQL Server.Also, I personally faced a problem when we implemented a CRM application over SQL Server.I was told that SQL Server has a limit on the size of the row and that if the row is greater than a certain size, then you need to split the row and insert into two tables with parent child relationship.This happened about a year back and I am not sure whether it is fixed or not.The company tried to migrate their CRM from Oracle to SQL Server but only ended up spending millions to find out that it is not going to work.They are continuing with Oracle now.Harvinder S. writes I found your article very informative.Here are some observations 1 Quote Also, SQL Server will escalate row locks to page level locks when too many rows on a page are locked.From my understanding, SQL Server never escalates row level lock to page level lock.It will aquire pagerow lock at the beginning and escalate to table level lock if needed.Quote In T SQL there are significant extensions to the ANSI SQL 9.The INNER JOIN, LEFT OUTER, RIGHT OUTER JOIN syntax differs from the classic JOIN.I find these extensions to be very beneficial for writing efficient code.I totally agree that SQL Server should have the following features Minus.Partitioning. Indexes bitmap, function based, etc.Better error handling.Better locking mechanism.I hope the next article will be show SQL Servers advantages over Oracle.Patrick M. writes Pure dribble.Clearly the author is an Oracle bigot.For someone that is certified in MS, he sure did get some major items wrong about MS SQL.Clearly he develops with Oracle and has only played with SQL Server, otherwise he would know better.Stored procs are compiled in MS SQL.Oracle Joins Where Clause Join Left Right Outer.INSERTINTO title VALUESBA, Bachelor of Arts INSERTINTO title VALUESBS, Bachelor of Science INSERTINTO title VALUESMS, Master of Science INSERTINTO title VALUESPh.D, Doctor of Philosophy INSERTINTO title VALUESMD, Doctor of Medicine INSERTINTO personpersonid, firstname, lastname, title1VALUES1, Daniel, Morgan, BS INSERTINTO person personid, firstname, lastname, title1VALUES2, Jack, Cline, BA INSERTINTO person personid, firstname, lastname, title1VALUES3, Muriel, Dance, Ph.D INSERTINTO person personid, firstname, lastname, title1VALUES4, Elizabeth, Scott, MS INSERTINTO person personid, firstname, lastnameVALUES5, Jacqueline, Stough INSERTINTO personrole VALUES 1, Administrator INSERTINTO personrole VALUES 2, Professor INSERTINTO personrole VALUES 3, Instructor INSERTINTO personrole VALUES 4, Employee INSERTINTO personrole VALUES 5, Student INSERTINTO personrole VALUES 9, Alumni CREATE SEQUENCE seqprid START WITH 1 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 1, 2 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 1, 9 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 2, 3 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 1, 5 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 3, 1 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 3, 9 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 4, 4 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 5, 5 INSERTINTO personroleie VALUESseqprid.NEXTVAL, 5, 9 COMMIT.

Not from some friend of a friend of a friend, but from an actual dispensary in Boulder, Colorado.Boulder, like the rest of Colorado, has recreational marijuana dispensaries where you can purchase weed legally.It was cool. But while my partner had purchased legal marijuana in the past, I didnt know the first thing about the standard operating procedure of bud buying.If youre not a native, or are visiting a state just to get some cannabis while you vacation, you might want to adhere to a few easy to follow guidelines to make yourself a model dispensary customer.The dispensary, as well as the locals, will appreciate it.Keep Your ID Handy.Visiting a dispensary involves proving youre 2.ID.

You should be prepared before you walk in the door and familiar with what you might be interested in purchasing.That means doing a little research beforehand, checking out the dispensarys site and inventory, and asking friends more familiar with marijuana than you about the best way to get started if its your first time.Be sure to check their hours as well some dispensaries are open late, some open early, and some are closed on certain days of the week.Cameras and Phones are a No No.You should shy away from last minute lookups and sharing with the world your current weed friendly situation until youre home.I was nearly ejected from the first dispensary I visited simply because my DSLR was hanging off my wrist, despite it having a lens cap.Dispensaries have a pretty strict no photos policy that you should adhere to unless you want to get kicked out of the store.Latest trending topics being covered on ZDNet including Reviews, Tech Industry, Security, Hardware, Apple, and Windows.Be Nice to Your Bud Tender.Your bud tender is your marijuana middleman, the person behind the counter that helps you pick the right product.That means you should treat them with the same respect youd show your friendly neighborhood mixologist, and not like some stoner who just loves weed.Theyre happy to help as long as youre polite.Ce Tiles 1 0 Serial Crack For Adobe' title='Ce Tiles 1 0 Serial Crack For Adobe' /> Roboform Enterprise Reviews For JobsDig Into Nearly 3.Years of Free Classic Science Fiction.If youre a fan of classic science fiction from the likes of Ray Bradbury, Isaac Asimov, and Robert A.Heinlein, youre in luck.Roboform Enterprise Reviews Lax' title='Roboform Enterprise Reviews Lax' />Archive.Galaxy Science Fiction for you to peruse for free.If you need to take a break and have some fun, the Internet Archive has gathered over 9.Read more Read.

Last.Pass is a no brainer for anyone who hasnt yet started using a password manager.Last. Pass has the broadest platform support of any password manager I saw, either free or paid.Its autofill feature is flexible and nicely designed.You can securely share selected passwords with other people theres also an Emergency Access feature that lets you give a loved one or other trusted person access to your data.An Automatic Password Change feature works on many sites to let you change many passwords with one click, and a Security Challenge alerts you to passwords that are weak, old, or duplicates, or that go with sites that have suffered data breaches.Last. Pass works on mac.OS, Windows, i. OS, Android, Chrome OS, Linux, Firefox OS, Firefox Mobile, Windows RT, Windows Phoneeven Apple Watch and Android Wear smartwatches.Sorry, no Black. Berry, Palm, or Symbian support.Its available as a browser extension for Chrome, Firefox, Safari, Internet Explorer, and Microsoft Edge, and it has desktop and mobile apps for various platforms.You can access Last.Pass in a browser extension, on the Web, or in a stand alone app.If you have a Chromebook, Last.Pass is your only good option, as it can run entirely as a Chrome extension.Password and Dashlane also offer Chrome extensions, but they rely on background apps that dont run in Chrome OS.And although several other password managers also work on ChromebooksKeeper, Logme.Once, and Robo. Form, with Enpass support in developmenttheyre less capable than Last.Pass overall. When you first log in on a site for which Last.Pass hasnt already stored your password, it prompts you to do soclick or tap Save Site, confirm or edit the details, and then click or tap Save.The next time you visit that site, Last.Pass fills in your credentials by default though you can disable auto file per site if you prefer you then need only click Log In or the equivalent button to log in.If even that is more effort than you want to expend, you can ask Last.Pass to log you in automatically for any given site, although doing so may increase security risks.Handling saved credit card data is also simple, although Last.Pass always requires you to take explicit action before filling in your credit card number.If you need to give someone else access to one or more of your passwords without sending the info in plain text, you can share it using Last.Pass the other person will need to have or create a Last.Pass account to view or use a shared password.However, this sort of sharing is one way any later changes you make to that login in your vault wont sync to the other person.The solution here is the 2.Premium subscription, which lets you set up a shared folder thats accessible for up to five people of your choicethe contents of that folder sync automatically when someone makes changes.In addition, you can designate someone as an emergency contact who can request access to your data under exceptional circumstancesif, for example, you die or become incapacitated.Before that access is granted, the person must wait for a period of time you set between 3 hours and 3.Dashlane offers a similar emergency contact feature 1.Password does not, although it provides numerous other ways to securely share passwords.One of my favorite Last.Pass features, Auto Change Password, comes in handy if a site has had a security breach or you simply realize your old password is too weak.When you select a site in Last.Pass and click the Auto Change Password link, Last.Pass logs in to that site with your existing credentials, generates a new random password, changes your password on that site, and updates its own database with the new password.This otherwise tedious process couldnt be easier the only catch is that it currently works with only about 8.Chrome and Safari.Dashlane has a comparable feature 1.Password does not.Most of the password managers I tested have some sort of security audit feature that checks for passwords in your database that are weak, old, or duplicates from other sites.Last. Pass calls this feature Security Challenge in addition to the checks I just mentioned, it also alerts you to passwords saved for sites known to have had security breaches.Password offers a similar capability, called Watchtower.Last. Pass works well on mobile platforms, too.Although the mobile versions arent quite as convenient to use as the desktop versions owing to operating system restrictions, all the major features such as adding and editing logins, contact info, and credit cards generating new passwords and adjusting most preferences, are present on i.OS and Android, and fingerprint identification is supported on compatible devices.It even works on Apple Watch and Android Wear smartwatches, on which you can search and display your passwords and other secure data.A Premium subscription to Last.Pass costs 2. 4 per yearfar less than 1.Password or Dashlane subscriptionsand adds shared folders, desktop application passwords Windows only, several additional multifactor authentication options for logging in to Last.Pass itself such as Yubi.Key and Sesame, desktop fingerprint identification, 1 GB of encrypted cloud file storage up from 5.MB for free accounts, and priority support.Enterprise accounts are also available, with prices starting at 3.At the end of summer 2.Last. Pass plans to launch a new feature called Last.Pass Families, which will allow family members to securely share passwords, bank account information, passport numbers, and so forth.You will be able to add and remove family members at any time, and control which passwords each person can access so you can give your child the garage door key code, but not your credit card number.The feature will cost an extra fee for both Premium paid and Standard free users of the app, although Premium users will get a free six month trial of Families when it launches.When it becomes available, well test it out as soon as we can and update this guide with our thoughts.
