• How to block a select statement for a table of the specified until validation line

  Hello
  
  How to block a SELECT statement for a specified row in a table until willingness to engage occure?
  
  My procedure is part of a Stock request and if a user (X) get stock 1 piece, another user must wait for the user (Y) complete his reportoire.
  
  So, let say my stock have 10 pencils.
  
  When the X user starts the Stock_PLS procedure, in table Stock, line (e.g. R1) that user X should work with it, must be lock up to what the commit / rollback will appear.
  
  procedure Stock_PLS...
  
  Start
  ..
  pencils: pencils-1 =;
  ..
  End
  
  Observation-> pencils: = 9;
  
  
  This means that is a user there, run SELECT * stock of the table where rows_id = R1, SELECTION should wait the Stock_PLS started by user X will be completed (with commit or rollback) and his SELECT should return the value 9.
  
  What I need, is that Oracle has something like LINE EXCLUSIVE TABLE LOCK, but in my situation the SELECT statement should be denied on the specified lines, until the end of the procedure.
  
  Kind regards

  Hello
  You can achieve this using the update with the Select clause.
  You can write your select statement like this
  SELECT * from stock of the table where rows_id = R1 for update;

• How to INSERT a SELECT statement with a GROUP BY clause on a table with an IDENTITY column?

  n an application, I intend to truncate and insertion on a 12 c Oracle database, but have found this problem with a IDENTITY column. Even if the INSERT... SELECT statement works on most SELECT uses I tried, if this statement was also a GROUP BY clause, it does not work, delivering a "ORA-00979: not a GROUP BY expression ' complaint. Some examples of code:

  create table aux ( owner_name varchar2(20), pet varchar2(20) );  
  insert into aux values ('Scott', 'dog'); 
  insert into aux values ('Mike', 'dog'); 
  insert into aux values ('Mike', 'cat'); 
  insert into aux values ('John', 'turtle');  
  
  
  create table T1 (
    id number generated always as identity,
    owner_name varchar2(20),
    pet_count number ); 
  select owner_name, count(*) as pet_count from aux group by owner_name; -- works just fine
  insert into T1 (owner_name, pet_count) select owner_name, count(*) as pet_count from aux group by owner_name; -- doesn't work
  

  The select statement works by itself, but it fails as an INSERT... SELECT statement.

  Appreciate the help!

  Looks like a bug. You must open the SR with Oracle. Meanwhile, you could materialize select:

  SQL > insert into T1 (owner_name, pet_count)
  2 with t as (select / * + materialize * / owner_name, count (*) as pet_count to the owner_name group)
  3. Select owner_name, pet_count t
  4.

  3 lines were created.

  SQL > select * from t1;

  ID OWNER_NAME PET_COUNT

• How to upgrade a selection one line of the table based on values in another table when there is exactly one matching entry and negligence if there is more than a football game

  Hello

  I'm trying to achieve the following objectives:

  1. in table A, select rows based on the values in column 2. something like SELECT * FROM TABLE A WHERE (COLUMN2 = 'X' or Column2 IS NULL)

  2 and these values selected, I want to update Column3 from Table A if TableA.column1 = TableB.column1, but only if there is exactly one game. If there are multiple matches, column 3 of the table article updated.

  That's what I've tried so far.

  UPDATE TABLE_A

  SET

  TABLE_A.COLUMN3 = (SELECT COLUMN3 OF TABLE_B

  WHERE ((TABLE_B.COLUMN1 = TABLE_A.COLUMN1) AND ( TABLE_B.COLUMN1 IN (SELECT Column1 FROM TABLE_B GROUP BY COLUMN1 , HAVING COUNT (*) = 1)))

  WHERE EXISTS (SELECT * FROM TABLE_A)

  WHERE ((TABLE_A.COLUMN2 = 'X' OU TABLE_A.COLUMN2 = 'Y') AND (TABLE_A.COLUMN4 IS NULL OR TABLE_A.COLUMN4 = ' ')));

  More details on my DB environment:

  Version Info:

  Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production

  PL/SQL Release 11.2.0.4.0 - Production

  Toad, but, depending on whether the query updated all lines. I would really appreciate if someone could tell me how to fix my request.

  Thanks in advance.

  Exists it predicate in the block of update will be set to true if there is at least one row in table_a where column2 is X or Y and column4 is null or a space. You need to correlate exists it with the outer query query (I'm guessing on column1) to get the result I think you want.  However, who would update all rows in table_a who meets the criteria, there is a corresponding row in table_b, affecting Column3 lines form null not matched or not.  (Again), I'm guessing that's not your intention.  If you only want to update the lines in table_a which have a corresponding line in table_b and meet the other predicate, then I think you want something more like:

  Update table_a

  Set table_a.column3 = (select column3 of table_b

  where table_b.column1 = table_a.column1 and

  Table_B.Column1 in (select column1 from table_b

  Group by column1, having count (*) = 1))

  where ((table_a.column2 = 'X' ou))

  table_a.Column2 = 'Y') and

  (table_a.column4 is null or)

  table_a.column4 = ' ')) and

  table_a.Column1 in (select column1 from table_b

  Group by column1, having count (*) = 1)

• How to write a single line instead of the entire port?

  Hello

  I followed the example for writing to the digital line as follows

  int taskHandle;

  given int [8];

  char linename [] = "" dev2/port0 / line0:7 ";"

  DAQmxErrChk (DAQmxCreateTask ("", & taskHandle));

  DAQmxErrChk (DAQmxCreateDOChan (taskHandle, linename, "", DAQmx_Val_ChanPerLine));
  DAQmxErrChk (DAQmxStartTask (taskHandle));
  DAQmxErrChk (DAQmxWriteDigitalU8 (taskHandle, 1, 1, 10.0, DAQmx_Val_GroupByChannel, data, NULL, NULL)); Here the data have 8 digits
   
  Error:
  SetWaitCursor (0);
  If (DAQmxFailed (error)) DAQmxGetExtendedErrorInfo (errBuff, 2048);
  If (taskHandle! = 0)
  {
  DAQmxStopTask (taskHandle);
  DAQmxClearTask (taskHandle);
  }
  If (DAQmxFailed (error)) MessagePopup("DAQmx Error", errBuff);

  The example above shows how to write 8 binary to 8 lines, but how to write only one line? I try the following code, but it does not work

  char linename [] = "dev2/port0/line 2;

  ...

  DAQmxErrChk (DAQmxWriteDigitalU8 (taskHandle, 1, 1, 10.0, DAQmx_Val_GroupByChannel, & data [2], NULL, NULL)); Here the data have 8 digits

  The data format for the DAQmxWriteDigitalLines() function will do exactly what you want.

  The data format for the DAQmxWriteDigitalU8() function is a full port (even if you do not have a value of a harbour full of lines in your task).

• How, in Illustrator CS5, select all objects with the three points (or nodes)?

  I'm fairly new to Illustrator, but it seems like it should be simple.  (It's trivial in CorelDraw X 4: after selecting an object with three knots, I go to Edition > search and replace > find objects > find objects that correspond to the currently selected object and navigate the menus left.)

  In Illustrator CS5, select options > identical do not seem to include the selection of all objects with the same number of nodes under the currently selected object.

  A double click on the magic wand tool also does not provide such an option.

  Thanks for any help.

  PS also useful would be knowing how to add other criteria to this search, for example, how to select all objects with three points * and * the current fill color.

  I'm afraid that you have better luck with the number of anchor Point.

Please watch this and guide me.

  Sorry for the late reply. Here is the VI, I hope it works for you. Rather than each element of the index and the addition of the row header, take advantage of the available icons and play with the nodes of property for a good solution.

• How oracle write "Checkpoint is not complete" in the journal of alerts?

  DB version: 10.2.0.4/RHEL 5.8

  In a batch run, we met a lot of 'Checkpoint not finish' errors in the alerts log.

  Later we discovered that the ORLs were only 50 MB in size and that DB had only 3 redo log group. Since this is the likely reason, we will create at least 10 groups of Redo log and increase the size of Redo log at 500 MB.

  But I want to know what exactly are the causes oracle to write "Checkpoint is not complete" in the journal of alerts?

  For the purpose of this discussion, I guess we have only 1 ENT by redo log group. Is my assumption correct below?

  ORL1

  |--> ORL1 file got full, then LGWR begins writing to the file ORL2. Control point occurs at the command of journal

  |                    DBWR writes updated the blocks associated with the entries of data files again ORL1

  |

  V

  ORL2

  |-> ORL2 file obtained full, LGWR wants to start writing to the file ORL3. Checkpoint is initiated to the log command.

  |                    But the control point cannot be completed for reasons unknown

  |

  V

  ORL3

  |---------------->

  Your assumption is only partially right.

  I like to illustrate

  ORL1

  |

  |---> ORL1, file got full, then LGWR begins writing to the file ORL2. Control point occurs at the command of journal

  |                    DBWR begins writing modified blocks associated with the entries of data files again ORL1

  |

  V

  ORL2

  |---> ORL2 file obtained full, LGWR begins writing to the file ORL3.

  |                    Checkpoint for ORL2 is initiated to the log command.

  |

  V

  ORL3

  |

  |---> ORL3 queue (the last member) also got full very quickly. LGWR wants first of all the 'new round '.

  writing (re-use) to ORL1. But the outlined point of control of the previous cycle ORL1 journal is

  not finished yet! .

  Basically, you get this error when LGWR tries to reuse a log file of roll forward online (ORL1 in the example above) and considers that it cannot be.

  This is because the remaining files (ORL2 and ORL3) ORL got entirely written before DB writer finished modified checkpointing associated blocks ORL1 again.

  Until the ORL1 control point is completed, DB crashes effectively and user sessions must wait until LGWR can reuse safely ORL1

  Yes can help a larger size of log roll forward to 10 groups. , But make sure that the input/output subsytem where are stored the ORLs has no latency problem.

• We can use EXISTS in which the condition

  Hi all
  We can use EXISTS (instead of IN) in which the status of a query that is not part of a subquery?
