  Hi Joop,

  Create each drawing as a drawing or a relational model in a drawing?

  As a relationship in a drawing model.

  How can I refer to the other schema view in the query designer

  You have a set a display scheme that you create. If the objects used in the view definition belong to another scheme they are included with the schema name in a generated select statement. By default the objects in the same schema (such as the view) are not prefixed with schema name - if you want that the schema name to include, then check the box 'Schema to include in the query name' on the view dialog box.

• Modification of the data types of the custom shared variables

  My application includes a library containing a number of shared single process variables. I use type defs to create the shared variable "of the custom control." I know that shared variables do not-automatic update since the type defs, so I'm updating shared variables (data type, do a right click, properties) whenever I update the type definitions.  However, if I make a change to a type design that does not change the data type, for example to change the labels controls, these changes will be reflected in the shared variable.  The data types of variable window shared list contains entries for each previous update, which indicates he uses the previous entries.  How can I make the window of properties of shared variables 'forget' my previous defs type wandering without deleting the variable total? Withdrawal and replacement would be troublesome because the done variable references throughout my project.

  Thank you

  Wes

  The variable is not in the Distributed System Manager, or Manager of the Variable, and cancellation of the deployment has not been resolved.  However, I found Labview from closing completely and reboot clears the memory of the previously used custom data types that sees the library.  Thus, the effective workaround I found is:

  1 make a significant change to the data type of the type (per your suggestion) FED. Record.

  2 - redefine the variable screw-notice type FED.

  3. save the project. Close and restart labview.

  4 - the old def type is now disabled.

  5. return the significant change of the def type, implement trivial change and save.

  6 redefine the variable using the type correct now def. Viola!

  Thank you!

• ReadOnly user can access the other schema and change them

  Hello everyone,
  
  I created a readonly as this user in oracle 11g r2
  
  SQL > CREATE USER IDENTIFIED BY readonly readonly;
  SQL > GRANT CREATE SESSION, CREATE a SYNONYM to readonly.
  SQL > GRANT SELECT ON SA.vCustomerService TO readonly.
  
  But when I connect to the database and do a select like:
  SQL > SELECT * FROM ACC;
  I get the data in this table, even if I do an update on that table it works.
  
  What I am doing wrong that my readonly user always has full access to the other schema?
  
  Thank you in advance for your help!

  Check the permissions for this table - maybe some operations on this table are granted to the publc?

• When not data type of the variant of wire to the data?

  
  

  When the data type of the sink of the thread (its destination) database is well defined, LabVIEW makes a type definition back from the variant to the data output. It does not work on polymorphic functions and structures border entries, etc. It is usually harmless to leave the type continuous wire in most of the cases but do not forget that you let LabVIEW decide for you, how to convert the data.

  In addition, if you put the following line in your file labview.ini:
  
  coerceFromVariant = TRUE

  you will be able connect variant directly to the sink, without variation in data (and its error handling).

• A question about the conservation of fields (hour, min, sec) time DATE type in the table on the changes of NLS_DATE_FORMAT

  Hello

  Oracle version: 12.1.0.1.0 - 64 bit

                    OS:   Fedora Core 17 X86_64

  My question is about the conservation of fields (hour, minute, second) time DATE type in the array on NLS_DATE_FORMAT changes.

  Take the following test case:

  SQL> create table tmptab(dateval date);
  
  Table created.
  
  SQL> alter session set nls_date_format = 'yyyy-mm-dd hh24:mi:ss';
  
  Session altered.
  
  SQL> insert into tmptab(dateval) values('2014-01-01 00:00:00');
  
  1 row created.
  
  SQL> insert into tmptab(dateval) values('2014-01-01 10:00:00');
  
  1 row created.
  
  SQL> commit;
  
  Commit complete.
  
  SQL> select * from tmptab;
  
  DATEVAL
  -------------------
  2014-01-01 00:00:00
  2014-01-01 10:00:00
  
  SQL> alter session set nls_date_format = 'yyyy';
  
  Session altered.
  
  SQL> select * from tmptab where dateval > '2014';
  
  no rows selected
  
  SQL>
  

  I don't understand why it returns nothing. The second test case above insert statement inserted a line with 10 as the value for the time of the DATE field column dateval.

  Accordingly, while comparing this with the literal '2014' (which based on the new value of NLS_DATE_FORMAT = "yyyy" is implicitly converted to DATE), shouldn't the above query returns the line 2014-01-01 10:00 ?

  I mean, I changed the NLS_DATE_FORMAT but data from time in the table fields are preserved and that's why they should normally be taken into account in the comparison of date.

  What I'm trying to say is that for me (Please correct me if I'm wrong), no matter what NLS_DATE_FORMAT configuration is the following test

  SQL> select * from tmptab where dateval > '2014';
  

  is the same thing that

  SQL> select * from tmptab where dateval > to_date('2014-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss');
  

  And because the line 2014-01-01 10: 00:00 in the tmptab table. The following test

  2014-01-01 10:00:00 > to_date('2014-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')
  

  evolves normally true (beucase of TIME = 10 on the left side of the test) and therefore this line must be returned which is not the case in the test above.

  You kindly could you tell me what I misunderstood?

  Thanks in advance,

  This is the price for the use of implicit conversions. Implicit DATE conversion rules are not as direct as it can be assumed. In your case, all you provide is year as date format. In this case date implicit conversion rules assumes that month in the current month, day 1 and time as 00:00:00.

  SQL > alter session set nls_date_format = "yyyy";

  Modified session.

  SQL > select to_char (to_date ('2014 "), ' mm/dd/yyyy hh24:mi:ss') twice;

  TO_CHAR (TO_DATE('20)
  -------------------
  01/08/2014-00:00:00

  SQL >

  So, when you start:

  Select * from tmptab where dateval > '2014 '.

  Oracle implicitly converts date using "YYYY", which translates as August 1, 2014 '2014'. That's why your quesry returns no rows.

• convert the varchar2 data type to the data number type

  How to convert the varchar2 data type to the data type number.
  
  
  It looks like my data

  col1 varchar2 (50)
  col2 varchar2 (500);

  I need to create a table with the same columns with data like number types (19)
  
  can someone help me
  
  Thank you

  You have changed your original post, so now I see that you get the invalid number.

  This is why you should always avoid the varchar columns to store numbers or dates...

  Since your table source contains a nonnumeric value, you can write a pl/sql to convert data and see what records are false:

  SQL> insert into a (col1,col2) values ('xxxx','2345');
  
  1 row created.
  
  SQL> select * from a;
  
  COL1     COL2
  -------- --------
  1234     2345
  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));
  
  Table created.
  
  SQL> set serverout on
  
  SQL> declare
    2  cursor c is
    3  select * from a;
    4  begin
    5    for r in c loop
    6     begin
    7       insert into b values (to_number(r.col1), to_number(r.col2));
    8     exception
    9       when invalid_number then
   10        dbms_output.put_line('Row rejected: col1='||r.col1||' col2='||r.col2);
   11     end;
   12    end loop;
   13  end;

• Creation of Data Type when the script crashes LabVIEW

  When you use the script (LV2010) if I call the Create method of Data Type (available appeal node when a reference to the BD is cable), if I have all but 1 up to the wiring on 'style' terminal, LabVIEW, it blocks. LabVIEW then restarts with an error message saying that "the last time that you have run LabVIEW internal error or accident took place in lvmain.cpp, line 1756. If I have wiring 1 However, it creates a constant fine.

  I see in the context-sensitive help that it always creates a control at the start, but it seems that I can't get it to create a constant. So, okay, I decided to go around, create the constant, take the new object refnum he returned and there to change the constant in one control... but I can't get this work. Can someone point me in the right direction? Here is the code and the screenshot; This is a quick drop plugin.

  It is intended to run on a cluster that is perceived as an icon if you want to test, you need to create that.

  I presented the 'style' value, 0 if if you don't want to plant LabVIEW, set it up to 1.

  

  No time for an in-depth exploration now.  Create from Datatype killed my LV10.  What I was able to do after creating a constant of cluster, the consultation as an icon and select it.  (1) with the scripts, create a new VI and stick that the constant to figure (2) mount the pasted objected to the ClusterConstant and the change of control.

  I think I know where you're going, should be interesting.

• Data types in the design for the producer consumer model

  Is it possible for me to use any type of data in a model of design producer consumer, without specifying specific data type?

  what I mean is if there is a way to connect to a data type with which I can use any other type of data, not to mention that one that I have connected, and if not, how can I specify the data type for a number or any other data type, for use in a design of producer-consumer model?

  You can make a part of your cluster of data a Variant.  It will take any type of data.  A common architecture for the producer/consumer is a cluster which is an enum and a Variant.  The enum contains all possible "orders", you might want to send.  The variant contains data that could be of any type.

  Ungroup you in the consumer and get the enum and Variant.  Attach the enum to a case structure.  In the specific case, convert the variant type in a data type of regular LabVIEW and with it as you please.

• Change data type for the column in a table - Oracle 8i

  Team,
  
  I need to change a VARCHAR2 column in number.
  
  ALTER table xyz change number abc;
  
  By giving the above statement, it says I need empty this column before you change.
  
  I can't change the data type before emptying this column.
  
  Please indicate any other solution. Give me some suggestions.
  
  Empty the column for me here BIG task.

  user11081688 wrote:

  Not according to the documentation:

  You can change the data type of any column or decrease the size of the entire column if all rows in the column contains NULL values.

  Please indicate any other solution. Give me some suggestions.

  You can add another column with the correct data type.

  ALTER TABLE xyz ADD COLUMN def NUMBER;
  UPDATE TABLE xyz SET def = TO_NUMBER(abc);
  ALTER TABLE xyz DROP COLUMN abc;
  ALTER TABLE xyz ADD COLUMN abc NUMBER;
  UPDATE TABLE xyz SET abc = def;
  ALTER TABEL xyz DROP COLUMN xyz;
  

  If I remember correctly, Oracle 8i does not support the change of name of column if this solution is a bit more complicated than 9i and above. Another option would be to create a new table with CREATE TABLE AS... SELECT, drop the old one and rename a new one to the old.

• Conversion of a data type to the data type Timestamp Date equivalent

  I'm trying to use the date of update the son page to track sales phase changes that occur each day associated with a campaign. Reporting requirements are to break the daily accomplishments of the users each day from the previous week. I can't find any other date field which provides information on when a sales stage has changed.
  
  I've searched high and low and ordered Mr. Lairson (sp?) book, but can't wait until I get to solve my problem.
  
  Can someone advise, very explicitly since I was a novice, on exactly how to type such a conversion?

  I don't know if I understand your query exactly, however if you are looking to convert a timestamp value (i.e. Date of change) in a short date format, then you can use: -

  CAST (timestamp AS DATE)

  for example CAST (lead. (' "Last modified" DATE)

  I hope this helps.
