In list LIMIT

Is there a limit on number of values you can put in "IN" Clause?
select * from emp
Where deptno in (10,20,30,.....n)
Thanks in Advance

With an explicit list as in your example, the limit is 255 values. If you define the in list as:
WHERE col IN (SELECT col from table)
Then there is no limit.

  • IPhone 5s Recent Call List Limit

    What is the Recent Call List Limit for an iPhone 5s?
    Can you view the entire Recent Call List Limit from the screen?
    Today, as I would delete a call from the list, an older call would appear at the bottom of the list.
    Thanks!

    The Recent call list will display the last 100 calls.
    You can scroll through the list to see from the beginning to end.

  • Overcoming the IN LIST limit

    Hi,
    I've recently posted a question about this but right now, I'm to understand the concept. I'm going to give a bit of background in order to make it more understandable.
    We have an application in which an object (A) contains a list of objects (B). Each of these objects in turn may contain objects (C). Each of these is a different type of object
    Currently, we have designed a very simplistic pattern that follows:
    - Load all Objects A according to user criteria
    - Build a list of comma-separated IDs of Object A and retrieve Objects B using SELECT * FROM B WHERE ID IN (1, 2, 3, etc...)
    - Use the B objects returned to build a comma-separated list of IDs of Object B and retrieve Objects C using this list as: SELECT * FROM C WHERE ID IN (4, 5, 6, etc...)
    Now, this works, but only in very simple conditions.
    Obviously my main concern is that it just won't work if you return more than 1000 Objects A or B at any point in time. The main problem I am facing now is regarding the way to make this work better, in terms of coding pattern and SQL optimization. IN is not that great with large sets as I understand it since it will use conditions such as 1 OR 2 OR 3 etc...
    I've checked out Tom Kyte's website and the table type solution (http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:110612348061). It works, but my string parameter passed in could be more than 4,000 bytes for large reports... Soooo, I kept on reading and saw the BULK INSERT idea.
    My question is the following: In an application where many users may run reports at the same time, is it even valid to consider doing this?
    - LOAD --> BULK INSERT --> LOAD USING BULK INSERTED VALUES --> CLEAN UP CUSTOM TABLE
    Hereby preventing other users from running their reports until this one is finished (unless I have one custom table per type of object)?
    Or is the simple: LOAD OBJECTS A --> LOAD OBJECTS B USING SUBQUERY TO LOAD OBJECTS A better from the beginning? My main thing against it is that we run a query again after we just ran it so we already have the data we need but we have no choice but to re-write it.
    I don't have anything against the BULK INSERT method etc... but for index usage and maintenance, the other solution just seems more complex for a performance that just would not be that great.
    What do you think about it? And if you have the same problem as I do right now, how do you go around it?

    Hi,
    No no it's my bad, I actually did not realize that I mixing up some programming and Oracle concepts without being specific.
    I'm assuming the problem with the 1000 list limit for an IN operator is understood though.
    We perform several SELECT statements to retrieve records from our database. These records are used to instantiate java objects (this is in a J2EE application server, not in the Oracle JVM or java pool at all).
    As an example (I apologize if it's a bad one), on the java side, we have a motherboard. It can contain one or more RAM slots. Each ram slot may contain a RAM module in it (for the sake of the example, I'll say it can contain one or more modules, just like old sockets...). On the database side, we have a MOTHERBOARD table, a RAMSLOT table, and a RAMMODULE table.
    My question was the following: a user may run a report saying that he/she wants to get all motherboards' information in the database. Right now, the way it's been made is that we select all motherboards, get their unique identifier and build a comma-separated list of these ids (in the java code), and then do a
    SELECT * FROM RAMSLOT WHERE MOTHERBOARD_ID IN (1, 2, 3 etc...).
    And the same is done between RAMSLOT and RAMMODULE. The problem is that if more than 1000 motherboards exist, it just won't work.
    Now, when I was looking at the ways to overcome this problem, I went to the Tom Kyte article mentioned. One solution is to create a function that will return a custom table type when passed in the string '1, 2, 3, etc...'. While this works with a small number of motherboards, well, if we loaded a lot of them and went over 4,000 bytes, we get a 'String Literal too long' error. This was mentioned on the AskTom article, to which the followup was: 'use BULK INSERT'. This is why I mention it. I guess what was meant is to load all the data in the custom type table and then perform as before.
    This is why I was wondering how this could possibly be better than just re-writing the query as a subquery later (as undesirable as it might be).
    Thanks for the help and please answer if anything isn't clear.

  • Parameters, dropdown list limit

    i am using a dropdown list of companies.
    as part of my parameters to run my report.
    i think the limit of the dropdown list is 150.
    how do i make it bigger?  i think i have 210 companies... or something like that
    thanks, Jon

    Hi Jon,
    Well, the limit is not 150 but 1000.
    Crystal Reports only shows 1000 list of values by default. This is, however, controlled by a registry key and you can increase it like this:
    Go to regedit (start > run > regedit) Browse to the location:
    HKEY_CURRENT_USER\Software\Business Objects\Suite 12.0\Crystal Reports\DatabaseOptions
    Create a new key called 'LOV' here and then on the right-hand side create a new string value called 'MaxRowsetRecords' with a value higher than 1000, perhaps around 10000.
    Now, this will increase the total values in the list, however it will still show 200 in one page/batch. To increase the batch size and make sure all the values appear a single list there is another registry key:
    Browse to:
    HKEY_CURRENT_USER\Software\Business Objects\Suite 12.0\Crystal Reports\ReportView and look for a key called 'PromptingLOVBatchSize'. Double-click the key and select 'Decimal' and set the value to 5000. Then, make sure you select 'Hexadecimal' and click OK. (We've noticed sometimes that the value is not saved unless we keep Hexadecimal selected).
    Restart Crystal Reports designer and you should have all the values in one batch.
    Let me know how this goes!

  • Multiselect (or just select) list limit

    Hi There,
    Does anyone know if there is a limit to the number of items than can be submitted when using a multiselect (or a shuttle).
    I have a query that returns hundreds of values (all valid). The user is going to need to select 1,2,5... all the way to ALL of these items to be used in another query.
    When I select ALL returned items, I get a browser error (Web page cannot be found - Error 400). This is in IE 8 (I know, I know, not my choice!!).
    Thoughts?
    My shuttle is based on a dynamic LOV which seems to be operating correctly.

  • SCEP Exclusions lists limit

    Hi all is there a limit to System Center Endpoint Protection with SCCM 2012 R2 exclusions for files, extensions and paths?
    I'm looking into creating a global server policy and a global workstation policy which will be aimed to be deployed to 5000 workstations and 600 servers.  I'd like to have the policies as minimal as possible so to avoid having to create multiple collections
    to target to.
    Based on based on our current Symantec environment we have over 150 file extension exclusions 100 folder paths and  and under 50 processes that we want to add to exclusions.
    Would it be wise to have limited policies?  Is there any performance impact if there are soo many exclusions listed under 1 policy?

    It depends on how you setup these policies. One good practice could be setup exclusion base on target users. For example you might have several exclusions for PCs targeted to trusted developers while you won't exclude anything when it is target public PC
    or security-critical systems.
    Before deploy them try run a small testing environment and try apply your policies and monitor their impacts on the system (e.g. performance, scan duration, etc.)

  • Creative Zen Album Track Listing Lim

    Is there a 0 track limit for albums? I just added a new album to it and it only accepted 0 tracks (there are 2). Then it made another file to put the other 2 tracks.

    No, I don't think there is any such limit with that model either. How many albums do you have on there? Is this happening with every relevant album?
    edit: I might know what the problem is. It reads ID3 tags, so if those other two files have a different artist listed or name variation then it will be placed in a different area.Message Edited by ssjmichael on 05-06-2006 03:24 PM

  • Distribution list limits

    According to http://support2.microsoft.com/default.aspx?scid=kb;en-us;238569&Product=out the distribution list limit is based on the property size limit of the computer that is running Exchange Server. The property size limit for an Exchange server is
    about 8 kilobytes (KB). The Exchange server stores all contact links in one property store.
    Does anyone know how i can see current property size of distribution list, or free space in property store?

    You are looking at the size limits for an Outlook Personal Distribution List in that KB article, not an Exchange distribution group. I've seen Exchange groups with tens-of-thousands of members.  The limit is not set by a property limit in the Exchange
    directory, and indeed, I don't know that there is a limit.

  • Unity 4.x - Limits of Distribution List members

    Is there a limit to how many members you can add to a public and/or private distribution list in Unity 4.2?

    Hi Johnny,
    Subscribers > Class of Service > Features Page 
    Lists Available to Subscribers
    Enter a number between one and 99 to specify the maximum number of private lists available to subscribers who are assigned to this COS. Subscribers can manage their private lists by phone and from the Cisco Unity Assistant.
    Though both the Cisco Unity conversation and the Cisco Unity Assistant use this setting to determine when a subscriber has reached the maximum number of lists, consider that each application calculates the number of lists that a subscriber owns differently:
    •When a subscriber tries to use the phone to create a new list by adding members, the Cisco Unity conversation counts the number of private lists that have members, and then compares the total to the value in this setting to determine whether the subscriber has reached the list limit. Lists with no members (empty lists) are not included in the total number of lists that a subscriber owns, even if the lists have recorded names and/or text names.
    •When a subscriber tries to use the Cisco Unity Assistant to create a new list, the Cisco Unity Assistant counts the number of lists that have a recorded voice name, a text name or members, and then compares the total to the value in this setting to determine whether the subscriber has reached the list limit. Lists with no members are included in the total number as long as they have recorded names and/or text names.
    This means that if a subscriber belongs to a class of service that allows 15 lists, and the subscriber has 12 private lists with members and two lists with recorded names but no members, the subscriber can potentially create more lists by phone than in the Cisco Unity Assistant before reaching the list limit:
    •When the subscriber uses the Cisco Unity conversation, the subscriber will reach the list limit either by adding members to the two empty lists and creating one new list, or by creating three new lists. If the subscriber reaches the limit by creating three new lists, the subscriber cannot add members to the two empty lists until two lists are deleted.
    •When the subscriber uses the Cisco Unity Assistant, the subscriber will reach the list limit by creating one new list. Despite reaching the list limit, the subscriber can add members to the two empty lists.
    You can set up private lists for a subscriber on the applicable Subscribers > Subscribers > Private Lists page, though the subscriber is the only person who can send voice messages to the list.
    Maximum Members Per List
    Enter a number between one and 999 to specify the maximum number of members that subscribers can add to a private list when they use the Cisco Unity conversation or the Cisco Unity Assistant. (There is no limit imposed on the number of members that can be added to a private list when you use the Subscribers > Subscribers > Private Lists page to add members to a list.)

  • AutoComplete not working properly in Outlook 2013

    The AutoComplete List is a feature which displays suggestions for names and e-mail addresses as you begin to type them. These suggestions are possible matches from a list of names and e-mail addresses from the e-mail messages that you have
    sent.
    AutoComplete is a convenient feature when we send an email message, if it suddenly stops working, it becomes a real pain to the sender. If you encountered this problem, you can use the steps below to troubleshoot it and make it work again.
    1. Check if the AutoComplete feature is turned on.
    By default, the AutoComplete feature is enabled. If it isn’t working, of course the first thing to check is whether the feature is enabled. To check it, go to
    File tab> Options > Mail, scroll down to the
    Send Messages section and make sure the “Use Auto-Complete List to suggest names when typing in the To, CC, and Bcc lines” option is selected.
    2. Check if AutoComplete works in OWA
    Since Outlook 2010 and Outlook 2013 doesn’t store nicknames in .NK2 file, it stores the autocomplete cache in the user’s mailbox and caches to a local cache file. So, the OWA uses the same autocomplete list, we can log into OWA and check if AutoComplete
    works.
    If it works in OWA, it means the autocomplete list is OK. The problem lies in the Outlook client side. If the autocomplete doesn’t even work in OWA, the autocomplete list could be corrupt.
    3. An Add-in may cause AutoComplete to not work correctly.
    Problematic add-in may cause a number of issues in Outlook. If an add-in cause Outlook to crash, the AutoComplete lists could be affected and become corrupt.
    To determine if a problematic add-in is the culprit, go to File > Options > Add-ins, disable all add-ins and then check if the problem continues. If the problem is gone with all add-in disabled, we can try re-enabling add-ins one-by-one to isolate
    the problematic add-in:
    (1) Start Outlook.
    (2) On the File tab, click Options,
    then click Add-Ins.
    (3) In the bottom of the Outlook Options dialog box, make sure the
    Manage drop-down shows COM Add-ins, and then click
    Go.
    (4) In the COM Add-Ins dialog box, select to enable an add-in and then click
    OK.
    (5) Repeat step 4 until you have all of the required Outlook functionality and Outlook remains stable.
    If Outlook becomes unstable after re-enabling a particular COM add-in, disable that COM add-in and then contact the add-in vendor to see if they have an updated version that is more stable with Outlook.
    For detailed steps about this, you can refer to the following KB article and look at the “Re-enabling COM add-ins one-by-one” section.
    http://support.microsoft.com/kb/2934538
    4. Reset the AutoComplete list.
    If AutoComplete is enabled but still not working in OWA, it could be that the corruption within the AutoComplete list is causing auto-complete not to work correctly. You’ll need to manually delete the AutoComplete list to fix the issue.
    Note: You will lose all addresses stored in AutoComplete.
    If there is only one or several AutoComplete entries are corrupt, we can remove them by clicking ‘X’ or pressing
    Delete key.
    If all entries are corrupt, we can use one of the following two methods to delete the AutoComplete lists:
    Method 1: Use the Empty Auto-complete List button.
    1. Open Outlook.
    2. On the File tab, click Options > Mail
    tab.
    3. Under Send Messages, click Empty Auto-Complete List.
    It’s also recommended to untick the “Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines”.
    4.  Restart Outlook and tick the “Use Auto-Complete List to suggest names when typing in the To, Cc, and Bcc lines” box again.
    Test if the issue persists.
    Method 2: Use the /CleanAutoCompleteCache switch.
    1. Exit Outlook.
    2. Press Windows key + R to open the Run command.
    3. Type Outlook.exe /CleanAutoCompleteCache in the Run box and press
    Enter.
    5. Reach the maximum number of AutoComplete entries
    Outlook limits the number of entries that you can save in the AutoComplete list. If you find some names unexpectedly removed from your autocomplete list, you may consider this situation.
    Outlook 2013 has a limit of 1000 entries for the AutoComplete list. After you reach this limit, Outlook uses an internal algorithm to determine the best names to remove from the list. It does this based on a usage weighting. To avoid
    this situation, you can use one of the following two methods:
    Method 1: You can manually remove some AutoComplete entries that you no longer use. We can remove them by clicking ‘X’ or pressing
    Delete key as we mentioned in portion 4.
    Method 2: You can change the limit for the AutoComplete list by modifying the registry.
    Because this configuration is untested, we do not recommended it. If you have a larger AutoComplete list, you could also lose a larger number of cached entries if your AutoComplete cache becomes unusable because of corruption. Given this disclaimer,
    you can use the following registry data to increase the AutoComplete list limit in Outlook.
    Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these
    steps carefully. For added protection, back up the registry before you modify it.
    1. Exit Outlook.
    2. Start Registry Editor. Press the Windows key, type regedit and then press
    Enter.
    3. Add the following value:
    HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\AutoNameCheck
    DWORD: MaxNickNames
    Value: Type the number in
    decimal form.
    Note: Try increasing the limit by only a marginal amount to test the new limit. For example, to create a 20 percent increase in the limit in Outlook 2013, you would specify 1200 for the
    MaxNickNames value.
    4. Exit Registry Editor and restart Outlook.
    More information
    To avoid the risk of losing your AutoComplete list entries, it’s recommended to back up them regularly. In Outlook 2013, the AutoComplete list entries are stored in a hidden message in your default message store. To back up the entries, please follow
    these steps:
    1. Exit Outlook, and then close Outlook Web Access or Outlook Web App (OWA) on all workstations that are connected to your mailbox.
    2. Download and install MFCMAPI here:
    http://mfcmapi.codeplex.com
    3. Run mfcmapi.exe.
    4. Click Session > Logon.
    5. Select your profile, and then click OK.
    6. Select the data file that use your email address as the filename, and then double-click it.
    7. Expand Root Mailbox, and then expand IPM_SUBTREE.
    8. Find Inbox and right-click on it, and then click Open Associated Content Table.
    9. In the newly opened MFCMAPI window, under the Subject column, right-click the item that has the subject
    IPM.Configuration.Autocomplete, and then click Export Message.
    10. In the Save Message To File window, select
    MSG file (UNICODE) from the drop-down list, and then click
    OK.
    11. Select a folder location to which you want to save the message, and then click
    Save.

  • How can I tell what album a photo is in.

    Hi, Is it possible to be in my library and tell what album or albums a selected photo is in?
    Also does anyone know the limit to the number of albums you can have?
    Thanks

    Travis:
    Welcome to the Apple Discussions. Not really. You can create a smart albums that will show you which photos are not in any album, but I don't know of any way to do what you want to without some extra effort, i.e. create a keyword for each album and have those shown in the thumbnail view.
    There's no listed limit to the number of albums that can be used. There may be a practical limit in regards to scrolling, etc.

  • EA4500 only displays maximum of 9 connected devices?

    My EA4500 with the latest firmware will only display nine connected devices at a time. It also seems to randomly shuffle which devices to show as connected, even though several more than nine are connected and online. Does anyone else's device list limit itself to displaying only nine devices? The Linksys phone apps also display a maximum of nine devices. I like the routers new user interface and understand that it has received a lot of praise, however this is the second bug I've experienced in as many months (the first being a failure of the device list to update once devices are upgraded to Windows 8, requiring a reset to default settings in order to fix).

    Still no luck.  And incidentally, my Win8 computers have dropped off the device list again, along with my Win7 desktop connected via ethernet.  That makes all 4 computers now missing from the device list, plus a network attached storage device also missing.  All of these devices initially appeared on the device list, but have now disappeared. TV, Blu-ray and cellphones connect and update normally.  Everything connects and operates normally, they just don't appear in the device list.
    Linksys can't expect people to go through a device reset time and time again for what I know now to be just a temporary fix for this issue.  At this price point especially. 

  • How to limit the number of items in a KPI Status list web part?

    How to limit the number of items in a KPI Status list web part? There is no paging option for Business Category Status list or any limit can be made by changing the Item limit in default view unlike other SharePoint List web parts. So How to achieve it?

    Hi,
    According your post, I know you would like to set the item display limit in Status List web part.
    In the web part, the number of items to display is based on the view which you selected when configuring the web part. The default view for status list is status list view.
    However, I am not able to limit the items’ display number of the status list view. After changing the items limit, the list item displayed would not match the number specified by Item Limit. Thus, it is not possible to limit the number
    of items in the Status list web part.
    It could be a potential issue in SharePoint 2010.
    We will log this issue to our suggestion box. As after the submission, we may not have any time guarantee when the fix may be released, but it may come out on next cumulative update.
    Appreciate your time and efforts.
