  • Database advantages? Access, MySQL, msSQL, or any others?

    - by JimZ
    Dear all Stackoverflowers, I just started to learn programming and now I'm putting this question online based on a quote: no question is silly My work needs to develop a order system based on web, which wants a database system. Since using Excel for years as a general office user, I naturally turn this to Access. However, most people say Access is very limited comparing to MySQL or MSSQL, or any other more professional database system. But after developing some functions for my company's order system, I really find Access can fulfill my request. And I also tried MSSQL to develop, which I found it not quite convenient to use. I have searched in stackoverflow and find no general answer about my doubt. Now I am sincerely hoping some experienced and professional developers could clear my doubts. Now I'm listing some Access advantages, which I don't think other database system have. I hope you could help me also find these advantages in others. 1. Access is portable, I can just copy a xxx.accdb file to my company and continue with development. 2. Access is easy to generate helpful table, for example, it will automatically generate a field that can automatically count, could be used as primary key value. 3. it is more compatable with Excel, to display and filter data. 4. importantly, it nerely needs no environment to setup, just needs MS Office to be installed. ............others However, I also find some points that MSSQL is advantaged: 1. security reasons 2. easy to backup, ( just use BACKUP..... sql statement to do it) 3. can edit stored procedure to save some functions to database ...............others specifically, I wish some friends could tell me how to make other database portable? since I usually work both at home and in office. It's a headache to move MSSQL work to my office, since the version of MSSQL is not the same. Thank you all and best regards, :)

  • Why do I get Bind Variable "DeliveryDate_Variable" is NOT DECLARED(Completely New TO Oracle)

  • Oracle query with LOWER

    Hi. Why this returns 0 rows SELECT GARTUSERID, USER_CODE, UNITID, RANKCODE, RANKID, FIO, LOGINNAME, START_DATE, EXPIR_DATE, NOTE, POSITION, ISCHGPASSWORD, IS_EXPIRDATE, IS_BLOCKED, ROW_ID FROM ACONTROL.GARTUSERS WHERE LOWER(LOGINNAME)=LOWER(:LOGIN) AND ROW_ID=:MD5PSWD and this returns 1 row (as I wanted for the first query)?

  • Concatenate and group multiple rows in Oracle

    - by user1693347
    Suppose I have a table like this: NAME GROUP name1 groupA name2 groupB name5 groupC name4 groupA name3 groupC I'd like to have a result like this: GROUP NAMES groupA name1,name4 groupB name2 groupC name3,name5 If there were only one column in the table, I could concatenate the records by doing the following, but with grouping in the context, I really don't have much idea. Any suggestion is welcome, thanks in advance! Concatatenating one column table: SELECT names FROM (SELECT SYS_CONNECT_BY_PATH(names,' ') names, level FROM name_table START WITH names = (SELECT names FROM name_table WHERE rownum = 1) CONNECT BY PRIOR names < names ORDER BY level DESC) WHERE rownum = 1

  • Storing and displaying unicode string (??????) using PHP and MySQL

    - by Anirudh Goel
    I have to store hindi text in a MySQL database, fetch it using a PHP script and display it on a webpage. I did the following: I created a database and set its encoding to UTF-8 and also the collation to utf8_bin. I added a varchar field in the table and set it to accept UTF-8 text in the charset property. Then I set about adding data to it. Here I had to copy data from an existing site. The hindi text looks like this: ????????:05:30 I directly copied this text into my database and used the PHP code echo(utf8_encode($string)) to display the data. Upon doing so the browser showed me "??????". When I inserted the UTF equivalent of the text by going to "view source" in the browser, however, ???????? translates into &#2360;&#2370;&#2352;&#2381;&#2351;&#2379;&#2342;&#2351;. If I enter and store &#2360;&#2370;&#2352;&#2381;&#2351;&#2379;&#2342;&#2351; in the database, it converts perfectly. So what I want to know is how I can directly store ???????? into my database and fetch it and display it in my webpage using PHP. Also, can anyone help me understand if there's a script which when I type in ????????, gives me &#2360;&#2370;&#2352;&#2381;&#2351;&#2379;&#2342;&#2351;? Solution Found I wrote the following sample script which worked for me. Hope it helps someone else too <html> <head> <title>Hindi</title></head> <body> <?php include("connection.php"); //simple connection setting $result = mysql_query("SET NAMES utf8"); //the main trick $cmd = "select * from hindi"; $result = mysql_query($cmd); while ($myrow = mysql_fetch_row($result)) { echo ($myrow[0]); } ?> </body> </html> The dump for my database storing hindi utf strings is CREATE TABLE `hindi` ( `data` varchar(1000) character set utf8 collate utf8_bin default NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; INSERT INTO `hindi` VALUES ('????????'); Now my question is, how did it work without specifying "META" or header info? Thanks!

  • Can't create directory named "mysql" in subversion repository

    - by High Ball
    I have a particular problem with subversion. Environment: subversion (1.6.12dfsg-6), apache2 (2.2.16-6+squeeze7) + mod dav_svn. I can't create a directory named "mysql" or "testmysql" or add and commit a file named "mysql.txt" in my repository. There are many references to "subversion PROPSET 403 forbidden" problems in google and so on. But I can use all functions of subversion. I can also create a directory named "hugo" or "test". My repository works properly. Only "mysql" doesn't work.

    MySQL's query cache is an impressive piece of engineering if sometimes misunderstood. Keeping it optimized and used efficiently can make a big difference in the overall throughput of your application, so it's worth taking a look under the hood, understanding it, and then keeping it tuned optimally.

  • Now It’s Personal (Although It Should Always Be): Campus Recruitment

    - by user769227
    One of the things that I think is important and I want our Campus Recruitment Team here at Oracle to be known for is outstanding customer service. When I say customer service, I mean both students and hiring managers should feel they have had a great experience in our campus hiring process. I think one of the keys to providing outstanding customer service is being able to provide as best as we can a personalised experience where the students who are interviewing with us feel like individuals in our process and not just part a ‘campus drive’. In the campus world this can be challenging at times especially in countries where there is high volume hiring. It can be tricky to create a personal experience when you are hiring for a large number of open graduate roles at one time. I think Campus Recruitment is one of the areas in the recruitment industry that is just waiting for a change. We have all seen the proliferation of Social Media in Recruitment over the past 4-6 years. Every Recruiter has a LinkedIn account or uses Twitter or G+ or FB, etc… and some individuals and organisations do it really well. Even in Campus Hiring there is great Social Media initiatives where companies reach out to students and talk to them. However one thing that has not really changed (and this is a generalisation) is the campus hiring interview process. Do these words inspire enthusiasm to you: “Group Interview, Assessment Centre, On-Campus Drive, Off-Campus Drive, etc...” I don’t know about you but to me these words don’t really sound very personal or individual to students. It almost conjures up images of a factory production line or those long queues you see where the person behind the counter says ‘take a number’. Campus Recruitment has come a long way don’t get me wrong – companies can share data with and talk to students in so many different ways now it really has become a much more transparent and open process. There are some times such as at IIT’s in India where it really is a bit old school in terms of interviewing with students running from company to company interviewing on campus over the course of a few days but I want students talking to Oracle to have as great an experience as possible (the outcome of getting a job or not is separate to the customer experience). As students, what are your thoughts? Do you feel like ‘just a number’ when you are interviewing or is there ways that companies can make the process more personalised. Let us know your thoughts. If you are interviewing with Oracle and have questions, want to talk to us or want to know what it is like working here – email us and we will help where we can. If you can’t reach your local Recruiter in your region email me at [email protected] and I will put you in touch with the appropriate person.

  • SQL SERVER – Weekly Series – Memory Lane – #033

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Spatial Database Definition and Research Documents Here is the definition from Wikipedia about spatial database : A spatial database is a database that is optimized to store and query data related to objects in space, including points, lines and polygons. While typical databases can understand various numeric and character types of data, additional functionality needs to be added for databases to process spatial data types. Select Only Date Part From DateTime – Best Practice A very common question which I receive is how to only get Date or Time part from datetime value. In this blog post I explain the same in very simple words. T-SQL Paging Query Technique Comparison (OVER and ROW_NUMBER()) – CTE vs. Derived Table I have received few emails and comments about my post SQL SERVER – T-SQL Paging Query Technique Comparison – SQL 2000 vs SQL 2005. The main question was is this can be done using CTE? Absolutely! What about Performance? It is identical! Please refer above mentioned article for the history of paging. SQL SERVER – Cannot resolve collation conflict for equal to operation One of the very first error I ever encountered in my career was to resolve this conflict. I have blogged about it and I have realized that many others like me who are facing this error. LEN and DATALENGTH of NULL Simple Example Here is the question for you what is the LEN of NULL value? Well it is very easy – just read the blog. Recovery Models and Selection Very simple and easy explanation of the Database Backup Recovery Model and how to select the best option for you. Explanation SQL SERVER Hash Join Hash join gives best performance when two more join tables are joined and at-least one of them have no index or is not sorted. It is also expected that smaller of the either of table can be read in memory completely (though not necessary). Easy Sequence of SELECT FROM JOIN WHERE GROUP BY HAVING ORDER BY SELECT yourcolumns FROM tablenames JOIN tablenames WHERE condition GROUP BY yourcolumns HAVING aggregatecolumn condition ORDER BY yourcolumns NorthWind Database or AdventureWorks Database – Samples Databases In this blog post we learn how to install Northwind database. I also shared the source where one can download this database as that is used in many examples on MSDN help files. sp_HelpText for sp_HelpText – Puzzle A simple quick puzzle – do you know the answer of it? If not, go ahead and read the blog. 2008 SQL SERVER – 2008 – Step By Step Installation Guide With Images When SQL Server 2008 was newly introduced lots of people had no clue how to install SQL Server 2008 and the amount of the question which I used to receive were so much. I wrote this blog post with the spirit that this will help all the newbies to install SQL Server 2008 with the help of images. Still today this blog post has been bible for all of the people who are confused with SQL Server installation. Inline Variable Assignment I loved this feature. I have always wanted this feature to be present in SQL Server. The last time when I met developers from Microsoft SQL Server, I had talked about this feature. I think this feature saves some time but make the code more readable. Introduction to Policy Management – Enforcing Rules on SQL Server If our company policy is to create all the Stored Procedure with prefix ‘usp’ that developers should be just prevented to create Stored Procedure with any other prefix. Let us see a small tutorial how to create conditions and policy which will prevent any future SP to be created with any other prefix. 2009 Performance Counters from System Views – By Kevin Mckenna Many of you are not aware of this fact that access to performance information is readily available in SQL Server and that too without querying performance counters using a custom application or via perfmon. Till now, this fact has remained undisclosed but through this post I would like to explain you can easily access SQL Server performance counter information. Without putting much effort you will come across the system viewsys.dm_os_performance_counters. As the name suggests, this provides you easy access to the SQL Server performance counter information that is passed on to perfmon, but you can get at it via tsql. Customize Toolbar – Remove Debug Button from Toolbar I was fond of SQL Server Debugger feature in SQL Server 2000. To my utter disappointment, this feature was withdrawn from SQL Server 2005. The button of the debugger is similar to a play button and is used to run debugging commands of Visual Studio. Because of this reason, it gets very much infuriating for developers when they are developing on both – Visual Studio and SSMS. Let us now see how we can remove debugging button from SQL Server Management Studio. Effect of Normalization on Index and Performance A very interesting conversation which started from twitter. If you want to read one link this is the link I encourage you to read it. SSMS Feature – Multi-server Queries Using SQL Server Management Studio (SSMS) DBAs can now query multiple servers from one window. It is quite common for DBAs with large amount of servers to maintain and gather information from multiple SQL Servers and create report. This feature is a blessing for the DBAs, as they can now assemble all the information instantaneously without going anywhere. Query Optimizer Hint ROBUST PLAN – Question to You “ROBUST PLAN” is a kind of query hint which works quite differently than other hints. It does not improve join or force any indexes to use; it just makes sure that a query does not crash due to over the limit size of row. Let me elaborate upon it in the blog post. 2010 Do you really know the difference between various date functions available in SQL Server 2012? Here is a three part story where we explored the same with examples: Fastest Way to Restore the Database Difference Between DATETIME and DATETIME2 Difference Between DATETIME and DATETIME2 – WITH GETDATE Shrinking NDF and MDF Files – Readers’ Opinion Shrinking Database always creates performance degradation and increases fragmentation in the database. I suggest that you keep that in mind before you start reading the following comment. If you are going to say Shrinking Database is bad and evil, here I am saying it first and loud. Now, the comment of Imran is written while keeping in mind only the process showing how the Shrinking Database Operation works. Imran has already explained his understanding and requests further explanation. I have removed the Best Practices section from Imran’s comments, as there are a few corrections. 2011 Solution – Puzzle – SELECT * vs SELECT COUNT(*) This is very interesting question and I am very confident that not every one knows the answer to this question. Let me ask you again – Which will be faster SELECT* or SELECT COUNT (*) or do you think this is apples and oranges comparison. 2012 Service Broker and CAP_CPU_PERCENT – Limiting SQL Server Instances to CPU Usage In SQL Server 2012 there are a few enhancements with regards to SQL Server Resource Governor. One of the enhancement is how the resources are allocated. Let me explain you with examples. Let us understand the entire discussion with the help of three different examples. Finding Size of a Columnstore Index Using DMVs One of the very common question I often see is need of the list of columnstore index along with their size and corresponding table name. I quickly re-wrote a script using DMVs sys.indexes and sys.dm_db_partition_stats. This script gives the size of the columnstore index on disk only. I am sure there will be advanced script to retrieve details related to components associated with the columnstore index. However, I believe following script is sufficient to start getting an idea of columnstore index size. Developer Training Resources and Summary Roundup Developer Training - Importance and Significance - Part 1 In this part we discussed the importance of training in the real world. The most important and valuable resource any company is its employee. Employees who have been well-trained will be better at their jobs and produce a better product.  An employee who is well trained obviously knows more about their job and all the technical aspects. I have a very high opinion about training employees and it is the most important task. Developer Training – Employee Morals and Ethics – Part 2 In this part we discussed the most crucial components of training. Often employees are expecting the company to pay for their training and the company expresses no interest in training the employee. Quite often training expenses are the real issue for both the employee and employer. Developer Training – Difficult Questions and Alternative Perspective - Part 3 This part was the most difficult to write as I tried to address a few difficult questions and answers. Training is such a sensitive issue that many developers when not receiving chance for training think about leaving the organization. Developer Training – Various Options for Developer Training – Part 4 In this part I tried to explore a few methods and options for training. The generic feedback I received on this blog post was short and I should have explored each of the subject of the training in details. I believe there are two big buckets of training 1) Instructor Lead Training and 2) Self Lead Training. Developer Training – A Conclusive Summary- Part 5 There is no better motivation than a personal desire to learn new technology. Honestly there is nothing more personal learning. That “change is the only constant” and “adapt & overcome” are the essential lessons of life. One cannot stop the learning and resist the change. In the IT industry “ego of knowing all” and the “resistance to change” are the most challenging issues. A Quick Look at Logging and Ideas around Logging Question: What is the first thing comes to your mind when you hear the word “Logging”? Strange enough I got a different answer every single time. Let me just list what answer I got from my friends. Let us go over them one by one. Beginning Performance Tuning with SQL Server Execution Plan Solution of Puzzle – Swap Value of Column Without Case Statement Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: SQL SERVER – A Puzzle – Swap Value of Column Without Case Statement. I have proposed 3 different solutions in the blog posts itself. I had requested the help of the community to come up with alternate solutions and honestly I am stunned and amazed by the qualified entries.

  • Customization: It’s Wanted in Enterprise Tech Platforms Too

    - by Mike Stiles
    Did you know that every customer service person does their job the exact same way in every business organization?  And did you know that every business organization cares about the exact same metrics? I hope not, because both those things couldn’t be farther from the truth. And if there are different needs and approaches in different enterprises, it stands to reason technology platforms must become increasingly customizable. Oracle Social Cloud sees that coming and is doing something about it, at least in terms of social media management. Today we introduce Social Station, a customizable user experience workspace within the Oracle Social Relationship Management (SRM) platform. We think a lot about customer-centricity and customer experience around here, and we know our own customers are ready to start moving forward in being able to set up their work environments in the ways that work best for them. That kind of thing increases productivity, helps deliver on social objectives faster, and generally just makes life more pleasant. A recent IDG Enterprise report says that enterprises currently investing in more consumerized, easy-to-use technologies experience a 56% increase in employee productivity and a 46% increase in customer satisfaction. Imagine that. When you make it easier and more pleasant for employees to help customers, more customers get helped and everyone ends up happier. So what does this Social Station do and what does it mean, exactly? It’s an innovative move to take some pretty high-end tech (take a bow developers) and simplify it, making things more intuitive: Drag and drop lets you easily build out and personalize your social workspace with different modules. The new Custom Analytics module can mix and match over 120 metrics with thousands of customizable reporting options. You can check constantly refreshed updates and keep a real-time eye on the numbers you’re trying to move. One-click sharing and annotation in the Custom Analytics module improves sharing and collaboration across teams, departments and executives. Multi-view layout helps you leverage social insights by letting you monitor conversations by network, stream, metric, graph type, date range, and relative time period. The Enhanced Calendar is a better visual representation of content, posts, networks and views, letting you easily toggle between functions and views. The Oracle Social Station sets us up to always be developing & launching additional social modules for you, covering areas like content curation, influencer engagement, and command center creation. Oracle Social Cloud Group VP Meg Bear says, “Consumers today have high expectations of their technology application capabilities and usability, and those expectations don’t stop when they enter their workplaces.” In other words, internal enterprise technology platforms must reflect the personalization and customization being called for in consumer products and marketing. “One size fits all” is becoming an endangered concept. @mikestiles @oraclesocial
