• Not Null on the column of a primary key constraint

  I came across a table defined in the same way to...
  
  create table t (t_id int constraint nn_t_id not null constraint pk_t primary, data key number);
  
  Of course, the primary key is the is not null, then is there a reason to add the redundant constraint not null?

  There are two parts to your question, I think:

  (1) why add a NOT NULL if a primary key is also reported.
  (2) why is null is NOT a name defined by the user (in this case nn_t_id).

  1 > I think you are right: there is no difference in behavior in the way that Oracle is going to reject the creation of NULL in this column (whether through the direct insert or update with a NULL value). I personally always declares the NOT NULL for columns, I know to never have null, regardless of whether the column is (member of) a PK.

  It's pretty funny, btw, the SQL standard as chosen able to be the NULL default value. I think that we all type much less, if the SQL standard chose NOT NULL default value. But that's another story.

  2 > I don't see given nullability defined by the user of the explicit names now and then, because of some "coding guideline' which dictates that constraint names must never be generated System. This guideline is often presented as a result of the exception handling of "client-side", where the constraint name is filtered SQLERRM and then more personalized to be displayed to the end user. However for NOT NULL constraint violations, I think (does not fully to check) that you are always thrown an ORA-01400 is an ORA-01407. Who nowadays both will tell you exactly (in SQLERRM) which column of this table is currently in violation of a NOT NULL constraint.

• View of the column in the Finder

  OK, so I've had this problem before, but it sets out of himself, do not know how, but it just resurfaced again.  Normally, for the column, you can drag the width of the columns and make as wide or narrow as you want.  However, the mine at that time the bar doubled with the cursor instead of simple lines... and I can't adjust the columns...  Don't know what it is or how it goes.  Not sure if I am fairly clear in my description, but I add a page to help.

  Does anyone else have this and no idea how to change this?  I can't find anything in the Prefs or display Options or anywhere else.  I had to restart Finder in the Force Quit Applications window, so I don't know if that has anything to do with it.  Have also restarted my MBP as well.  I had posted a discussion about this before and can't remember if someone did or not, but I'm not.

  Thanks for your replies.

  Manfred Hi, I saw this behaviour a couple of times.

  Go to your 'Go' menu Finder, hold the option key and choose the library. Then go to the preferences and trash folder these files:

  com Apple.sidebarlists.plist

  Then, restart or log in and again.

  (You will have to reset some finder prefs the way you like them).

• Impossible to disable the column "Preview" in the Finder Windows

  Before that I describe this problem, I just want to clarify that I have configured Finder to always open folders in a new window, and while some of my files are put into mode icon that the majority is set to display in the list.

  Following an upgrade to Yosemite to El Capitan, some of my Finder list view windows began to show the column "Preview" on the side of the far right, after the date modified column. I don't like this feature because when none of the folders or items are selected it shows just a ugly "blank" space in the window. So, I quickly discovered that I can disable this "Preview" column by selecting "hide the Preview" in the view menu.

  The problem is that once I chose this, in many of my files change does not stick. After a reboot or a restart, I'll go back to the window and the preview column is again. Sometimes it happens immediately after closing the window and opening it again. The worst culprit is my user folder.

  I tried selecting "Hide Preview" and then enter the display options and set as the default view for all Finder Windows, but this makes no difference.

  Anyone know how to disable the overview at all times column in all the windows in the Finder?

  This is what it looks like in my folders set to display from the list:

  

• A loop until the end of the column

  Hello!

  I have a string type 2D table that I want to loop through. The output of the table is feeding an "analysis of the string" vi and then converted into a timestamp. The problem is that the column of my table 2D is a different size. This means that some columns have a few empty cells towards the end of the column. When the cells are feed to the 'string analysis', and it occurs. I want it first is research in the table and delete all of the empty cells or find a way to the loop to the bottom of the column and stop when empty cells begin. The table is not fixed, then it is impossible to use a constant here. Can someone help me on this one?

• Increase the length of the column - restriction key foreign vs MS SQL

  Hello

  I need to increase the length of the column (nvarchar) in some tables. Between these tables are foreign keys.

  When I try to do it on MS SQL databases using the command as "ALTER TABLE TABLE_NAME ALTER COLUMN column NAME NVARCHAR (50) NULL" then I get the error like below:

  Column ' dbo. TABLEA. NAME ' is not the same length or scale as the referencing column or the 'FKNAME' object depends on the column 'name'.

  Therefore resume, on MS SQL I drop all constraints, alter table and re-create constraints.

  When I do this same thing on the oracle database (oracle database a same pattern as MS SQL database, same fk, same tables, columns, etc.) using the command as "ALTER TABLE table_name MODIFY COLUMN NVARCHAR2 (40);  " then length is change without any erros and I wounder t - it a correct situation on oracle? -all the constraints are enabled. Oracle checks the length of data to foreign key columns?

  As I understand the error (ORA-02267: column type incompatible with the type of the referenced column) is the show that if the data type name is not equal between data tables not type length (?)

  To reproduce:

  1 create tables

  CREATE TABLE "TABLEA".

  (ACTIVATE THE 'NAME' NVARCHAR2 (20) NOT NULL,)

  NUMBER OF "TEXTID",.

  'PK_TABLEA' CONSTRAINT PRIMARY KEY ("NAME")

  );

  CREATE TABLE 'TABLEB.

  (SELECT 'ID' NUMBER NOT NULL,)

  NVARCHAR2 (10) "NAME."

  NUMBER OF "WWW."

  "TABLEB' ('ID') PRIMARY KEY CONSTRAINT

  );

  2. create the fk

  ALTER TABLE TABLEB ADD CONSTRAINT FK_TABLEB FOREIGN KEY ('NAME') REFERENCES 'TABLEA' ('NAME');

  On MS SQL, you get an error message on the same length of column ;) no

  Thank you

  Best regards

  Whatever it is, the answer seems to be here: https://docs.oracle.com/cd/E17952_01/refman-5.5-en/create-table-foreign-keys.html

  "Corresponding columns in the foreign key and the referenced key must have similar data types. The size and the sign of the integer types must be the same. The length of the string types are not necessarily the same. For the non-binary (character) string, the character set and collation columns must be the same. "

• Can someone tell me how to expand the columns of names of files in file Explorer?

  In each program, I've never used, all the user has to do to make a column more wide is to click on the divider bar at the top (or the side of the column) and drag the wider column. Instantly. Easily. Nearly second nature without looking.

  Now, clunky Windows 8 coming, and it's so frustrating!  I went on line and saw hundreds of people griping about the same and some of the answers are right-click on the column heading and click on the size, or to choose the longest title in your file and right click and choose the size of the car, but I don't have any of these options.  I right click on the longer title and don't get choices such as car size or size.  There is not a definable column header.  Above the list of files is a bunch of stuff in the Ribbon, none of this centered above the list of files.  Above, there are a few possibilities for right click produce the word "size" in the box that opens, but is not an active link, and I can't click on it.

  I'm amazed that I bought this "top of the new version of line everyone will go to" and it does not with ease.  It is not calculate how wide to make the column... computers are great to calculate.  Why not Windows 8?   When a program allows you to work harder, take four or five steps to do one thing, that is not good design. He should do it for us, we should not be on the right side of the mouse, click on the left side, etc.

  My main question is how to do widen the column, and my secondary question is how can we get Microsoft to listen to us?  I read the comment after comment on dozens of complaints, which is one of the most common.  Thus, besides wishing they would listen to us... I'll call their hotline tomorrow and complain... what someone knows in the meantime what can I do to see all the title of my files?  Right now they are all cut in half way through.  I want to enter this bar on the right and drag it to the right to reveal the name of file in the way of how work most computer programs.

  It almost seems as if Microsoft tried to make it more difficult for their base of users and new users.   It boggles the mind.

  Of course, I'd appreciate it if someone can tell me if it is still possible to make the column wider, and I would love it if there was a response that is easy without going through a lot of steps.  Thanks in advance to anyone out there who has thought about it!

  Happy new year!

  CG

  There is no difference in the way you make the columns wider if I understand the question.
   
  I guess you see something like this (without the arrows highlighting red and pointing to the column headings and separators that you hover over, click on + hold and drag to make greater/smaller in the method you describe):

  

  Or are you speaking of something else than the "File Explorer" you mentioned in your question?
   
  Also - if you get the "double-arrow" cursor hover at the same place as you would drag to the size of column wider or narrower and rather - double-click on - it (as it always has) calculates the necessary width to see everything in the column to the left of the separator you are clicking on and re - size accordingly.
   
  I think that the right click of the column header (see section highlighted above) and change the size to fit refers to this menu, you would get when right-clicking on the column headers highlighted in the picture above...

  

  Now there's something for everyone - you have to be in DETAILS view (as always) in order to get these beautiful columns.  "Very large icons', 'Large icons', 'medium-sized icons", "Small icons", "List", "Tiles" or "Content" views will not have columns to sort by...

  

  In addition, if you notice in the last frame, in the "Détails" view, you must, depending on the size of your window, see "All columns to fit the size" as an option in the view menu.
   
  And the "size of all columns to fit" as shown in the two methods I could think casual to show calculations for all columns and adjusts large/more details for all visible columns in the display of the Explorer of files in all areas.
   
  Oh - and in case you want to "Détails" view to be the default view from this moment for your windows 'Windows Explorer '... Change to it (as shown above) and find the 'Options' button in the top Ribbon (usually the one furthest to the right) and click on it (not the arrows on the side of it - click it to select it) and should open a new window called "Folder Options."  Select the 'view' tab and click on "apply to folders" and all other folders that you open from the moment which will 'View' by default (unless you change it.)  * Special note * here - you can be originally 'Computer' or 'My PC' Windows Explorer - display you must have at least one folder of the selected (such as "drive Local (c)") drive and active in order to see the button 'Apply to records' assets to click.
   
  New - this is essentially the same since Windows XP.  Some of the options have changed names (heck, even Windows Explorer is referred to as 'This PC' now instead of 'Computer' and 'My Computer') and there were a few additional views added and deleted - but even advanced stuff are quite similar to the latest methods to infer.
   
  Hope that helps.  Ask if you have any other questions and please come back anyway let everyone know if the response was satisfactory!

• Chains of substitution in the column link attributes

  I use this attribute a lot recently to activate the link columns in reports to the pleasant appearance buttons, using the same set of classes used by the button model options, for example:

  class="t-Button  t-Button--warning t-Button--simple t-Button--stretch"
  

  Instead of use the chain, I would like to set it either by using a chain of substitution of application to create consistency, or the columns of the region to provide classes based on a condition of level line.

  

  I spotted some differences in behavior between classic and IR and 5.0.1 and 5.0.2. I am not too concerned by version differences because the progress is there, but I want to ensure further progress.

  I have an example here, ws (swesley/otn/forum) connection details

  https://Apex.Oracle.com/pls/Apex/f?p=88776:3

  For both types of reports, the EMPNO uses & BTN_CSS. to supply the value of a string substitution of application. It works for the IR, but not for the classic. Instead, I see

  <a href="javascript:void(0);" &btn_css.="">7369</a>
  

  The ENAME field uses #LINK_ATTRIBS # the source of the value of the SQL. The caveat here is that the LINK_ATTRIBS column must escape special characters the value no. It works in 5.0.2 but not 5.0.1. The latter treats the string as if it has not been dropped?

  

  My solution is to provide

  class="#LINK_ATTRIBS#"
  

  where the sql returns just the set of classes, not the full html tag.

  This problem has recently been described in the mou channel # _Suit.

  Hi Scott - thank you for viewing this issue, I am agree that traditional reports that should support the do of reports interactively. So, I advanced and implemented this change for APEX 5.1.

• all the columns in a database instance

  Yes, there is ALL_TAB_COLS.

  'ALL' in ALL_TAB_COLS, as in ALL_TABLES. You hear all those you have privileges to see, not necessarily those in the database.  The data dictionary views whose names begin with DBA_ (for example, DBA_TAB_COLS and DBA_TABLES) include all those in the entire database.  Usually, not everyone is allowed to use the DBA_ views.

• retrieve the value column access via the variable name of the column

  I need to build a function of validation with this condition:

  The data model is like this:

  We have an array of items_general, with its id and data.

  Then we have specific tables, let's say... item_especific1, item_especific2 item_especificn. They have the same as the table of the item_general pk and fk against item_general

  Each element is in one of the tables item_specific and items_general.

  
  

  Now, the validation feature: I need to check for an element, if some special columns of the item_especificx table are null and will raise an error if this occurs.

  I got the name of especific_table and the list of names of particular column stored in another table.

  
  

  I guess I can browse this list of column table to build a clause concatening Dynamics 'and' | column_name | 'is nothing', but I'm not a big fan of the dynamic sql.

  
  

  Can you think of a better solution? Any way to access the value of the column by using the column name, as if it were a varchar2 key index?
  

  
  

  
  

  
  

  Nope, no filter.

  When you have a funky data like that model, you're destined to dynamic sql and other assortment of headaches.

• A statement UPDATE changes the line if the update changes the column even value?

  HI -.

  I have a main classification and the corresponding audit table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time. He is not able to determine that the value is the same.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  Best regards

  I have a main Table and the corresponding Audit Table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Why?

  You try to resolve what made you what are the PROBLEM that select as the solution?

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time.

  Yes - it is EXACTLY what you say that you wanted to do and EXACTLY what the code does in this article.

  He is not able to determine that the value is the same.

  I think you mean that the code does NOT check if the value is the same. You can certainly change the code to do this check. But I have a question to start with your need for such a solution.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  OK - then modify the code to check EACH COLUMN and compare its NEW value to the OLD value and insert only the table of audit if SOME (or columns you care specifically) have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  It depends on what you mean by 'change the line '. Of course to update a column with the SAME value does not change the resulting data value.

  But the physical structure of the line, the location of the pieces of line and information in the header block (YVERT, etc.) will change. And, as others have said Oracle doesn't know and doesn't care, so if the new value of a column is the same as the old value will create redo, undo and the rest.

  Start over and tell us what PROBLEM you're trying to solve. Then we can help you find the best way to solve it.
