• Can't understand why this query returns multiple lines with the same data

  Hi all
  I am a relative novice and self-taught when it comes to SQL. I wrote a query to our reporting tool that returns multiple rows, and I can't understand why. I know that I can use the SELECT DISTINCT option, but it really slows the execution when I do. I'd really rather understand if I can change the code to avoid the multiples. This is the query. I've included a few statements in italics to help explain the break. Any ideas?
  
  SELECT MATSITE, MATPONUM, FIRSTRECPTDATE
  Of
  Subquery that concludes the first date on which purchase orders have been implemented with ACK State
  (SELECT ACKSTAT. PONUM AS 'ACKPONUM', (MIN (ACKSTAT. CHANGEDATE)) AS 'FIRSTACKDATE '.
  OF PZMAX. POSTATUS ACKSTAT
  WHERE (ACKSTAT. STATE = 'ACK') AND (ACKSTAT.ORGID ='CGSALTUS)
  GROUP OF ACKSTAT. PONUM),
  Subquery that concludes the first reception against a purchase order transaction for purposes of comparison
  (SELECT TRANS. PONUM AS "MATPONUM", TRANS. SITEID AS 'MATSITE', (MIN (TRANS. TRANSDATE)) AS 'FIRSTRECPTDATE '.
  OF PZMAX. MATRECTRANS TRANS
  WHERE (TRANS.ORGID ='CGSALTUS) AND (TRANS. HOUR > =: startDate and TRANS. TRANSDATE < =: endDate)
  TRANS GROUP. SITEID, TRANS. PONUM)
  WHERE
  (ACKPONUM = MATPONUM AND FIRSTRECPTDATE < FIRSTACKDATE) OR (NOT EXISTS (SELECT 1 FROM PZMAX. POSTATUS ACKSTAT2 WHERE (ACKSTAT2. PONUM = MATPONUM) AND (ACKSTAT2. STATE = 'ACK') AND (ACKSTAT2.ORGID ='CGSALTUS)))
  
  The where the instruction is intended to find when one of two conditions exists. ((1) received happened before the command either in ACK or 2) a reception that's happened, but the purchase order is never in ACK State. It seems that this second condition that creates multiple lines.
  
  Any thoughts will be appreciated geratly.

  select salary from employees union select salary from employees;

  Hello

  See the docs.

  ' Example of the UNION
  The following statement combines the results of two queries with the UNION operator which eliminates duplicates of selected lines.
  "This statement shows that you must match the data type (using the function TO_CHAR) when the columns do not exist in one or the other table"

• TypeError: Error #1009: cannot understand why I make it

  Hi, I keep getting the error above, Error #1009: cannot access a property or method of a null object reference. and can't understand why I'm getting it.

  I get it in the last line of the following function:

  public function frameEvents (): void

  {

  _playerClass.update ();

  _playerClass.render ();

  _playerClass.updatePlayerShot ();

  _scroll.update ();

  _collision.playerVsGround (_playerClass, foreground1);

  _collision.checkBullets (_playerClass.playerShot.playerShot.bitmap);

  _bigTurretOne.update (_playerClass.xPos, _playerClass.yPos, _scroll.scroll_Vx, _scroll.scroll_Vy, _bigTurretOne.x, _bigTurretOne.y);

  _bigTurretOne.x += _scroll.scroll_Vx;

  _bigTurretOne.y += _scroll.scroll_Vy;

  _bigTurretOne.render ();

  _bigTurrShot.moveMissiles ();

  _collision.checkMissiles (_bigTurrShot._missile.bitmap);

  }

  When I trace (_bigTurrShot._missile.bitmap) I get [object bitmap] so it is not upward with the null value when it's mapped. Everything seems to be OK in the other code I have for it, anyone have any idea why I get the errror?

  It is reactionary and not very elegant but check if the object is not null before accessing its property. If _collision.checkMissiles(_bigTurrShot._missile.bitmap); is giving the null object error, try

  if(_bigTurrShot._missile != null) _collision.checkMissiles(_bigTurrShot._missile.bitmap);

  I recently moved from analytical functions - the PARTITION OF analytical functions I practised so far have prescribed a group by article.

  I don't understand why it does not include a.

  Any tips?

  There is no need to include a GROUP BY in your query, simply because you use analytical functions.

  The main point of the use of analytic functions is to allow you to perform the aggregation or other lines of reference data without having to group data in the normal sense.  The 'score' window, is what defines the data group that you want to reference without actually the outcome of consolidation.

• No. phones service smart blackBerry, cannot understand why.

  My Blackberry Curve has currently no service, and can't firure why. For the record, I'm home, and I've always had the service before. So here's what I can tell:

  * Instead of saying 'connected to T-Mobile' liike it usually does, on the front screen, it says: "failed to initialize."

  * In the State of the Service, only the voice service says "emergency".

  * In the Mobile Network Options, there my mobile network such as AT & T, but my network is T-Mobile, and I didn't AT & t at any time just by owning the phone.

  Any help? The last time something like this happened was when I forgot to pay my phone bill, butI talked to T-Mobile, and is not the problem. Thanks in advance!

  OK, so it seems that I answered my own question. I was still with my old phone SIM card, and he died. So I took one that came with my curve and has been change to T-Mobile to that one, and now it's great to be working again. Thanks for all the suggestions!

• Use of memory Windows 7 - excess and I cannot understand why

  I have a Windows 7 computer with gigabytes of RAM, which should be more than enough for a user like me. However, my computer has sometimes slows down, so I used the Task Manager. I discovered that too large amount of memory was used. This has steadily increased. Now, when I start my computer, my memory usage starts at 38% of the amount of space available and then increased to about 45% of the memory. The culprit is not a virus, as I did several malware analyses, nor is it a memory problem. Task Manager and performance monitor data just came over me, and I can't find the root of the problem. Can anyone suggest a solution or a way to understand the problem? Thank you!

• Hard drive shows almost full but cannot understand why

  Hello

  My C drive shows me using 565 GB with a total area of 596 GB so I'm close to running out of space.

  Strange thing is that I can't know which uses all the space!

  I looked at the size of all files on the C drive, and what follows is the biggest:

  Program x 86: 32 GB

  Windows: 50GB

  Users: 271GB

  Which makes a total of about 350 GB, this is far from the projection of 565 GB used when I look at the properties of the C drive.

  So, where's the rest?

  I have the list hidden files and I looked at disk cleanup and defragmentation.  I also deleted the files in system restore, but it's all the little things.

  The difference, I'm looking for is huge then where is he?

  Max

  Control Panel / System / Protection system allows you to choose the amount of disk space to use for the Restore Points. I use 5 GB that gives me about 6 points of restoration.

• My computer freezes and gets the blue screen at least three times a day. I cannot understand why, and I'm frustrated. Help, please!

  My computer makes sure to plant three to five times a day. It always ends with the blue screen of death and strong buzz. I think it's perhaps because of Spotify, but I've updated, reloaded and all and yet the program itself and my computer still seems to hang. I really don't think that it is good for my computer hangs at 3 times a day. I've had this computer for about 2 months and it is brand new. (Windows 7, I use Google Chrome, it's an Acer 5250-639.

  Although it suggests, it's the driver causing the problem it may not be the problem. However, it is a good place to start.

• That means 1e9 and why this query does not work?

  What does 1e9? Someone has links to documentation on this oracle? And why I get this error?

  SIZE is a keyword - so if you want the name of the column size then use 'SIZE' else give it a different name

• Why this query SQLLite returns the same all the time?

  Hello

  I use a search box to accept a query on three columns and am page before based on the last record, which in this case is Run Baby Run by Loopy

  I know for a fact that the database has a song inside by Loopy called Straight Down the Line, so this should at least be showing that. But it does is display the same songs again.

  Can someone explain the error in my logic here?

  SELECT * WHERE DiscID AS "loopy %" songs or artist LIKE 'loopy %' or AS "loopy %" title AND artist > = 'LOOPY' COLLATE NOCASE Title > = 'Run Baby Run' COLLATE NOCASE ORDER BY artist COLLATE NOCASE ASC, title COLLATE NOCASE ASC LIMIT 20
