• How to select a part of the message under macOS Sierra?

  In previous versions of Mac OS x, I was able to select a part of the message (text / iMessage) in the Messages application. Now, if I try to do the same, Tapback is enabled. It's really annoying, as I often have to copy the entire message body, paste into an editor and then to do the editing.

  Which should not happen if you simply select the text of the message by double-clicking or click-and - drag. That action works the same way it always has.

  Tapback happen if you press and hold - in other words, if do not quickly move the cursor.

• 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 select and default hightlight the first line in a programmatic Table(ADF Table created based on a SortableModel) ADF.

  Hi all

  
  

  We use JDeveloper Studio Edition Version 12.1.3.0.0 and deployed on GlassFish Server Open Source Edition 3.1.2.2 (build 5) and connect to the SQLServer database.

  
  

  We created a table ADF programming related to a SortableModel created programmatically to a bean.

  
  

  We need to select and highlight the first row in the table just after making it to retrieve data based on the first line.

  
  

  We tried the based on the following thread: How to call the bean support just after JSFF / page fragment loads? and a few other posts online, but it does not work very well.

  
  

  W has created a hidden text in the bottom of the JSF model as follows:

  
  

  < af:table varStatus = "rowStat" Summary = "table" value = "#{pageFlowScope.crudBean.dynamicTable.collectionModel} '"

  Rows = "#{pageFlowScope.crudBean.dynamicTable.collectionModel.RowCount} '"

  contentDelivery = 'immediate' var = 'row' rendered = 'true '.

  Binding = "#{backingBeanScope.crudBackingBean.tasksTable} '"

  selectionListener = "#{backingBeanScope.crudBackingBean.customListener} '"

  "rowSelection ="single"id ="t1"partialTriggers =": pt_gr2 "columnStretching =" column: clmn0 ">

  < af:forEach items = "#{pageFlowScope.crudBean.dynamicTable.columnNames}" var = 'name' varStatus 'vs' = > "

  < af:column sortable = "true" sortProperty rowHeader = "#{name}" = "no style" headerText = "#{pageFlowScope.crudBean.dynamicTable.columnLabel [name]}" "

  inlineStyle = "width: 100px;"  ID = "clmn$ {vs.index}" >

  < af:activeOutputText value = "#{row [name]}" id = "aot1" / >

  < / af:column >

  < / af:forEach >

  < / af:table >

  ....

  
  

  < af:outputText id = "hiddenOutputTextId" visible = "false" value = "#{backingBeanScope.crudBackingBean.afterPageLoad} '"

  Binding="#{backingBeanScope.crudBackingBean.hiddenOutputText}"/ >

  And we have added the code to the bean to support below:

  public String getAfterPageLoad() {}

  If (!.) {AdfFacesContext.getCurrentInstance () .isPostback ()}

  selectFirstRowInTasksTable();

  }

  Return afterPageLoad;

  }

  public void selectFirstRowInTasksTable() {}

  try {}

  RKS RowKeySet = new RowKeySetImpl();

  RowKeySet rksEmpty = new RowKeySetImpl();

  Model CollectionModel = tasksTable.getValue ((CollectionModel));

  ROWCOUNT int = model.getRowCount ();

  If (rowcount > 0) {}

  model.setRowIndex (0);

  Key of the object = model.getRowKey ();

  RKS. Add (Key);

  tasksTable.setSelectedRowKeys (rks);

  SelectionEvent selectEvent =

  new SelectionEvent (tasksTable.getSelectedRowKeys (), rks, tasksTable);

  selectEvent.queue ();

  customListener (selectEvent); / / to retrieve data

  AdfFacesContext.getCurrentInstance () .addPartialTarget (tasksTable);

  }

  } catch (Exception e) {}

  }

  }

  I think that () selectEvent.queue; should work even without calling the customerListener, but it is not working in all cases.

  What is the problem in my code?

  
  

  
  

  Have you tried to bind property of 'selectedRowKeys' to selection configuration / bean there?

  Something like:

  public RowKeySet getSelectedRKS() {
      if (rks == null) {
          // make first record as selected
          // create RowKeySet and assign it to rks variable(where rks is variable defined in bean with some scope higher than request scope)
      }
      return rks;
  }

• How to select objects? Thing the most annoing in Illustrator

  How can choose us object as this fire-logo on my screen WITHOUT also selecting a box around it?
  Whenever I select the whole of this object, not my logo itself.

  But don't tell me 'block the box first. There is no problem with this in Corel Draw. Illustrator you always select a lot more than what you want.

  

  The same video:

  Au2 you do not have something wrong,

  selection to...

  Illustrator = everything he touches (black arrow)

  Corel = only what is entirely contained in the selection encompassing

  That's the way it works, if you want to select the logo, select text scrolling, your logo, the way you do, then shift + click (deselect) on the small triangle, the gray background rectangle and "Che...". "text... as others have suggested.

  I want to get the chain between second and third underscore concerns underscore, i.e. "MEGAMART".
  How to achieve this in the sql statement.

  One way is to use SUBSTR and InStr.

  INSTR ( str,
        , '_'
        , 1
        , n
        )
  

  Returns the position of the n-th point in str.

  WITH     got_pos          AS
  (
       SELECT     str
       ,     INSTR (str, '_', 1, 2) + 1     AS pos_2
       ,     INSTR (str, '_', 1, 3)          AS pos_3
       FROM     table_x
  )
  SELECT     str
  ,     SUBSTR ( str
              , pos_2
              , pos_3 - pos_2
              )      AS part_3
  FROM    got_pos
  ;
  

  You don't need absolutely the subquery; You can repeat the INSTR expressions as arguments to SUBSTR if you wish.

  In Oracle 10 (and more), you can do ITI with less code, but once again the execution, by using regular expressions:

  SELECT  str
  ,     REGEXP_SUBSTR ( str
                  , '[^_]+'
                  , 1
                  , 3
                  )          AS part_3
  FROM    table_x
  ;
  

  Are you sure the chain will always at least 3 ' _? Everything would change if the channel started by a '_', or the 2nd '_' came immediately after the 1st? Post some sample data (CREATE TABLE and INSERT statements) and the results that you want the data and explain.
  Always tell what version of Oracle you are using.
  See the FAQ forum {message identifier: = 9360002}
