  Hi, I would do something like this* select * from cars_table where body not equal to null. select * from cars_table where values not equal to null And id = "3" I know the syntax for 'not equal' is <, but i get an empty results. For the second part, I want to get a result set where it only returns the columns that have a value. So, if the value is null, then don't include that column. Thanks

• Select JavaHelp topic in TOC when using setCurrentID

  - by dcstraw

  When I use HelpBroker.setCurrentID("[some help id]"), JavaHelp correctly shows the page I want but the associated topic is not automatically selected/highlighted in the table of contents. This makes it difficult for a user to know where in the topic tree the current page is located. Is there any way to programmatically highlight the current topic in the TOC when I use a HelpBroker to navigate to a specific Help page? Note that when the user follows links within the Java help system, the new topic is properly selected in the table of contents.

• Which's the best way to protect primary key on ASP.NET MVC?

  - by Junior Mayhé

  I'm creating a ASP.NET MVC website and I was wandering which techniques do you guys use to protect primary key on these mvc urls. Actually ASP.NET MVC generates this syntax for its urls: /Controller/Action/Id Last week I was trying to encrypt it using SHA-1 Encryption, but this encrypter generates some special symbols like + (plus), / (slash), and other annoying chars which difficult the decryption. Perhaps creating a custom encryption should solve the problem. But I wanna here from you guys, do you have some ideas to protect mvc urls?

• What's the different between these 2 mysql queries? one using left join

  - by Lyon

  Hi, I see people using LEFT JOIN in their mysql queries to fetch data from two tables. But I normally do it without left join. Is there any differences besides the syntax, e.g. performance? Here's my normal query style: SELECT * FROM table1 as tbl1, table2 as tbl2 WHERE tbl1.id=tbl2.table_id as compared to SELECT * FROM table1 as tbl1 LEFT JOIN table2 as tbl2 on tbl1.id=tbl2.id Personally I prefer the first style...hmm..

• Is Programming Right for me?

  - by L1th1um

  I'm interested in programming, but it seems to me that I can't get into it. Every time I've tried to learn a language and stuff by looking through tutorials or books I'd never get past the part where I use the syntax to make something. And by interest, I mean that I read stack overflow a lot, coding horror, and stuff but the actual coding part is hard for me to get into. Did anybody start this way? How did you get past this block?

• hibernate sybase db power function

  - by Vipin Thomas

  We are trying to use sybase function power to do mathematical calculation for one of the DB columns. The hibernate is generating power function as pow(?, xyzo0_.AmtScale) whereas sybase supports power function as Syntax POWER( numeric-expression-1, numeric-expression-2 ) We have tried modifying the hibernate.dialect. Have tried org.hibernate.dialect.SybaseASE15Dialect org.hibernate.dialect.Sybase11Dialect org.hibernate.dialect.SybaseAnywhereDialect but all dialects generate the power function as pow(?, xyzo0_.AmtScale). Is this hibernate issue or are we missing something?

• How does a compiler first compile itself in the same language?

  - by jdk

  I recently read the Mono C# compiler is able to compile itself using the C# language. Cool. In the past I've heard of other languages doing the same. It twists my mind - at inception seems like a chicken and egg problem: syntax vs compiler. What comes first, second and third, etc?...
