• Please let me know how I can add a new column with a constraint not null, table already has data, without falling off the table... Please help me on this issue...

  Hello

  I have an emp_job_det with a, b, c columns table. Note that this TABLE ALREADY has DATA OF THESE COLUMNS

  IAM now add a new column "D" with forced not null

  Fistly I alter the table by adding the single column "D", if I do, the entire column would be created with alll of nulls for the column DEFAULT D

  ALTER table emp_job_det Add number D; -do note not null CONSTRAINT is not added

  Second... If I try to add the constraint not null, get an eoor as already conatained null values...

  (GOLD)

  In other words, if I put the query

  ALTER table emp_job_det Add number D NOT NULL; -THROWS ERROR AS TABLE ALREADY CONTAINS DATA

  So my question is how how can I add a new column with a constraint not null, table already has the data, without falling off the table

  Please help me on this issue...

  Add the column without constraint, then fill the column. Once all the rows in the table are given in the new column, and then add the constraint not null.

• XMLTable to extract columns with conditional path does not

  Hello

  I am on 11.2.0.3 and I need to extract columns on a section of XML with conditions on, but I get "ORA-00907: lack the right parenthesis", so I think that the way I go about it is not supported or that I have somehow the wrong syntax or something.

  This is a very simplified what I'm trying to do (there could be several different entries in the < sets1 > and < sets2 > sections and they might be in different orders, is not as if I can always choose the first or the last):

  with sample_data as (select 1 id,
                              xmltype('<root>
                                         <sets1>
                                           <set1><set_name>name1</set_name><set_val>val1</set_val></set1>
                                           <set1><set_name>name2</set_name><set_val>val2</set_val></set1>
                                         </sets1>
                                         <sets2>
                                           <set2><set_name>name3</set_name><set_val>val3</set_val></set2>
                                           <set2><set_name>name4</set_name><set_val>val4</set_val></set2>
                                         </sets2>
                                       </root>') xml_doc from dual)
  select *
  from   sample_data sd,
         xmltable('<root>' passing sd.xml_doc
                  columns col1 varchar2(10) path 'sets1/set1[set_name=''name1'']/set_val',
                          col2 varchar2(10) path 'sets1/set1[set_name=''name2'']/set_val',
                          col3 varchar2(10) path 'sets2/set2[set_name=''name4'']/set_val') x;
  

  What I'm trying to get:

  COL1  COL2  COL3
  ----  ----  ----
  val1  val2  val4
  

  I know that I could separate the < set1 > and < set2 > nodes in their own xmltypes xmltable on it and then join them and make the necessary pivoting, etc., but when I try to start that against only 1000 lines, db do not love and ended my session! Therefore, I'm looking for a more elegant way to do it.

  Is there a way to do this in a XMLTABLE? Pointers are very welcome!

  It solves your problem of sample request and you get the output that show you.

   with sample_data as (select 1 id,
                               xmltype('
                                          
                                            name1val1
                                            name2val2
                                          
                                          
                                            name3val3
                                            name4val4
                                          
                                        ') xml_doc from dual)
   select x.*  -- change
   from   sample_data sd,
          xmltable('/root' passing sd.xml_doc  -- change
                   columns col1 varchar2(10) path 'sets1/set1[set_name="name1"]/set_val',  -- change
                           col2 varchar2(10) path 'sets1/set1[set_name="name2"]/set_val',  -- change
                           col3 varchar2(10) path 'sets2/set2[set_name="name4"]/set_val') x;  -- change
  

  As you can see, I've marked the lines that I've changed.  The error you saw came to use two single quotes in the COLUMN XPath instead to use double quotes.  Then I changed the XPath expression in the XMLTable brackets as well.

  I'm confused on what the columns you really want overall, in terms of how you know which values you want, or did you mean that you want something random sets1 and sets2.

  You store the XML file in a column of XMLType SECUREFILE BINARY, right?  It seems that you made previous visits, but just double check.

• How to avoid duplicates

  When I copy the contents of a folder on a USB key, I sometimes gave options to maintain two copies or ignore that (and others like him) in the folder I'm in that copy. I keep the video files in a video folder on a USB key and I try to copy C/disc/videos as often as possible. But sometimes, I don't know where I stopped the last time that the copy and select the files already in the destination folder. Why didn't we the possibility to jump if a duplicate constantly? Is there a way to prevent duplicate files when you do this?

  What type of USB key that you use? I use a 500 GB USB external hard drive and can't reproduce your problem, but mine is (well) permanently connected.

  I always manage the items I copy on records, so when I add new files they copied to a folder on the external drive. If I do double job inadvertently with something the only place where it is likely to be found in the previously copied folder, and it's a simple matter to check.

  Another point, when you copied elements on the external hard drive you by keeping the files on the drive or are you allow to delete?  -Thanks - r.

• How to avoid the stalemate between count with all and several calls from an EP getBackingMapEntry...

  We have a processor input, which initiates a transaction lite by calling getBackingMapEntry on several similar entries.  The same cache distributed these similar entries of accommodation also simultaneously services count with all call and we often a blocking scenario comes from the fact that the count with all call trying to access/key in the same cache block - but in a different sequence - date entry processor accessed (for example, the European Parliament access to similar input 1 then similar input 2 while the count with all attempts to block the same but entries in sequence 2) then the entry 1).  The obvious solution is to change the sequence entry processor accesses these entries to match the sequence used by the count with all operation, but we do not know what sequence consistency applies to operations NamedCache.getAll.  Anyone know?  We believe that we excluded (e.g., consistency does not consider wrt the count with all access sequence) the following:

  • The sequence in an ordered collection of keys such as a list that is passed as an argument to count with all operation
  • The hash code of the key value
  • Any use of Comparable on the keys

  We use 3.7.1 consistency where it varies between 3.7.1 and 12 c.

  Thanks in advance.

  We've thought of it (always happens shortly after the publication on a support site).  If anyone is curious, it seems that the binary class implements Comparable and that consistency sorts instance converted by binary key and access the Scriptures based on this order sorted.  If the entry processor converts the keys to binary instances, sorts and accessed in sorted order, there is no potential blocking (of our observations, at least).  It would be nice if Oracle should document this that people better understand how to write safe concurrent code.

• How to avoid cutting two identical letters with Grep?

  letters rr cannot not be cut at the end of a line

  not allowed

  Captain Achab strongly recriminated the Spanish slave - Cimar
  Ron

  permit

  Captain Achab strongly recriminated the Spanish slave - Ci

  Brown

  Captain Achab recriminated strongly the gue - Spanish

  rrilla

  If I insert a character style not to break the Word won't cut the words and will be probably poorly composed as words with these letters have legal partitions in other places: Ba ~ rran ~ that ~ lla

  I would say that the word in the screenshot has not added correctly and you must remove the ~ between the KR

  But more important, it's Spanish actually assigned to the text? You do this in the drop-down list in the character, the control panel Panel, or in the Formats of Caracter Advanced section of the paragraph style definition.

  Select cell B1 and type (or copy and paste it here) the formula:

  shortcut for this is:

  C1 = if (Len (a1) > 0, Member SUBSTITUTE (A1, B1 & "", ""), "")
