• How to create iMessage timestamps

  How can I create a timestamp in iMessage settings so I get info date and time of each text message I get. I have Android and it's automatic. It of not a big deal, but may be useful in trying to remember when you sent or received a message. Here is an example

  

  iMessages already are time stamped, but hidden by default. To see the time stamp, open any conversation, slide your finger on the message from right to left. However, once your finger is raised, the timestamp will disappear.

• Create custom timestamp

  Hello
   
  I work on an electricity network and have need to analyze the current and voltage values and display some graphics (power, RMs values).
  I have acquire voltage and current signals with the acquisition of data that works perfectly and save the data in a PDM file. This file is read later in another application that contains all the analyses of power using the Suite of electric power of Labview.

  I can trace all my outings with the date and the time at which the data were acquired (from the file time stamp) but the power on the output of 'power values VI', the values are shown without date or time and it is very important for me to trace the values of power at the right date Ant time.

  I thought to create a timestamp that is initialized with the value of the PDM file first. At each iteration of the loop for, I would add 0.2 second (each iteration corresponds to 10 cycles of the voltage and current signals = 0.2 second for a grid of 50 Hz, it also corresponds to the frequency at which 'power values VI' calculates the values of power) and transmit the data with records to offset.

  My question: is it possible? How can I do? (I don't know how to add time to a timestamp) and is there a better way to do this?

  I tried an answer for a long time! any help would be much appreciated.
   
  (My main VI is very ugly, I know, I just started making it and test things.)

  The easiest way would be to use time of wave table get.  Which returns an array of timestamps corresponding to your samples in your waveform were taken.

• How to create several timestamps fileds in EDS data object?

  Hi all
  
  
  I am creating BAM BOF EDS data objects. I have provided information for the connections of the DB, during the recording of the data objects its not allowing the fields of timestamps.

  Thank you.

  Hello

  Here is the SNA for this oracle docs question.from
  Note:

  Only the tables owned by the user are displayed when a data object is created on an EDS.

  Creating a data object with multiple fields of time on an EDS stamp is not supported.

• Is it possible to create a timestamp Date using a plug-in?

  I created a plug-in that converts PDF files into TIFF files.

  Is there a way to promote a TIFF file as it is created with a date/time stamp?

  I thought that it's basically the equivalent of creating a stamp or a comment to TIFF because it is generated or in the PDF file just before to be converted?

  Thank you

• Trigger - use one to create primary key values

  I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.

  I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.

  Here's what I have.

  CREATE TABLE HF_fishers

  (

  contact_id INT NOT NULL

  , name VARCHAR (25)

  , last_name VARCHAR (35)

  PRIMARY KEY (contact_id)

  );

  CREATE SEQUENCES HF_fishers_seq.

  Then I ran the following trigger:

  CREATE

  HF_fishers_seq_trigger RELAXATION

  BEFORE INSERTING

  ON HF_fishers

  FOR EACH LINE

  BEGIN

  IF (: new.contact_id IS NULL)

  THEN

  : NEW.contact_id: = NVL (: NEW.contact_id)

  HF_fishers_seq. NEXTVAL

  );

  END IF;

  END HF_fishers_seq_trigger;

  =============

  Then I executed the following SQL statement that gives the error.

  INSERT INTO HF_fishers VALUES('Jacob','Muller');

  But if I do everything is good except that it defeats the purpose of relaxation.

  INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');

  MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

  OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?

  -After the code trigger of Jaramillo

  INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.

  INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens");  -No trigger but get key duplicated,.

  INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.

  My mistake.  Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.

  So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine.  The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding.  Colon only works in a trigger without asking for confirmation.

  Here is the code and my exit I ran home

  DROP TABLE hf_fishers CASCADE CONSTRAINTS PURGE;
  DROP SEQUENCE hf_fishers_seq;
  
  CREATE TABLE hf_fishers
  (
  contact_id   INTEGER NOT NULL
  ,first_name   VARCHAR(25)
  ,last_name    VARCHAR(35)
  ,PRIMARY KEY (contact_id)
  );
  
  CREATE SEQUENCE hf_fishers_seq;
  
  CREATE OR REPLACE TRIGGER hf_fishers_seq_trigger

  BEGIN

        :NEW.contact_id := hf_fishers_seq.NEXTVAL;
     END IF;
  
  END hf_fishers_seq_trigger;
  
  INSERT INTO hf_fishers(first_name, last_name)
       VALUES ('Jesse', 'Owens');  -- Works with the trigger
  
  INSERT INTO hf_fishers
       VALUES (hf_fishers_seq.nextval, 'Jesse', 'Owens');  --Works without using the trigger body code.
  
  SELECT *
    FROM hf_fishers;

  Agree with the above.  Triggers (ab) should not be used in this way.  Nontransactional process should not be based on a transactional trigger.  These processes are part of the business logic and should be at the level of the company of codification (Summit, you can add a process to be executed once the completed insertion)

• Trying to create a trigger that adds a value to a field based on another field

  Hello

  Im trying to set a trigger that will add a field to a table if another field = the same thing and one where the condition is met, but can't seem to get anything to do and can't find anything online suggesting the syntax.

  the use of im tables are

  Students

  I need the trigger to identify if the 'status' field = applicant accepted when a new data column is added, if that is the case I need to identify the scope of student_number of applications_history and match it to the student_number on students field, I then need to add a 'Y' in the field 'put' corresponding to this student in the student table. I'm looking for without stopping for some type of syntax format online but could not find anything, is it still possible?

  Instead of, I have using the procedure to insert records in a table and then I created one by dbms_scheduler job.

  This discussion will be useful for any future reference.

  create or replace procedure p2
