Oracle SQL Developer - tables cannot be seen

Question

I was using SQL Developer 1 1  I have recently upgraded to SQL Developer 3  After the upgrade  I noticed that some of my connections do not show their tables  I can do a select on the tables and the data is shown  I can see other objects like views etc  I can still use my older version and can see all the tables listed fine for the same schemas  There are other connections that show up fine though   Cannot seem to find information on this  I tried removing the filter but it didn t work   Did anybody run into this  Please help

I have tried both the options suggested by Michael Munsey and works for me    I wanted to provide another option to view the filtered tables  Mouse Right Click your table trees node and Select  Apply Filter  and check  Include Synonyms  check box and click Okay  That s it  you should be able to view the tables right there  It works for me    Courtesy  http   www thatjeffsmith com archive 2013 03 why-cant-i-see-my-tables-in-oracle-sql-developer

I have the same problem in sqlDeveloper64-3 0 4 34 and sqlDeveloper64-3 1 07 42   According to https   forums oracle com forums thread jspa threadID 2202388 it appears there is a bug in the JDBC driver having to do with  Out Of Band Breaks  - basically a low level TCP issue    The workaround is launch sql developer with JVM property -Doracle net disableOob true I tried this solutions for 3 0 and 3 1 and it works   So I just quote here the solution from forum        I believe I have identified what is causing these issues for some users and not others  It appears there is a bug in the JDBC driver having to do with  Out Of Band Breaks  - basically a low level TCP issue  The bug seems to manifest itself in a number of ways  So far I ve identified using shared connections  particularly with Vista or Windows 7  and connecting over VPN  any OS  as common scenarios  In all cases  not having DBA access is also an issue       First  let me explain why DBA access makes a difference  When we first access any particular data dictionary view  we first try to see if we can get access to the DBA version of the view  or is some cases tab   etc   These views are much more efficient than the ordinary USER versions  so we want to use them if we can  We only check each DBA view once per session  and only when needed   but we can end up checking for access to a bunch of views       The OOB bug seems to rear its head when we do this check  We should get a nice  simple response back from the database  However  in the scenarios where the bug is occurring  this low level network bug is instead causing an error to occur that puts the connection into an unusable state  This then results in all the Connection Closed errors    There does appear to be a workaround - the JDBC driver supports disabling OOB  However  doing so will affect the ability to cancel an executing statement  So I wouldn t recommend using the workaround in general  but it should solve the issue for the situations where users are running into this specific problem       To enable the workaround  a Java system property needs to be set - oracle net disableOob true  You can set this in two ways  The first is to pass it in on the command line as sqldeveloper -J-Doracle net disableOob true  Of course  that only works if you are normally running from the command line  You can also add a line to the sqldeveloper conf file  located under  sqldeveloper bin    There the line would be AddVMOption -Doracle net disableOob true      We are looking into additional resolutions  but for now the workaround should enable you to work with SQL Developer       - John      SQL Developer Team

You probably don t have access to one of the meta tables that SQL Developer 3 is querying  If I picked the right query  it runs the following SELECT statement   select   from     SELECT o OBJECT NAME  o OBJECT ID     short name  decode bitand t property  32   32   YES    NO   partitioned                  decode bitand t property  64   64   IOT                  decode bitand t property  512   512   IOT OVERFLOW                  decode bitand t flags  536870912   536870912   IOT MAPPING   null    iot type            o OWNER OBJECT OWNER  o CREATED  o LAST DDL TIME  O GENERATED  O TEMPORARY  case when xt obj  is null then  N  else  Y  end EXTERNAL     FROM SYS Dba OBJECTS O  sys tab  t  sys external tab  xt     WHERE O OWNER    SCHEMA     and   o object id   t obj         and   o object id   xt obj         AND O OBJECT TYPE    TABLE   union all SELECT OBJECT NAME  OBJECT ID   syn SYNONYM NAME short NAME  decode bitand t property  32   32   YES    NO   partitioned                  decode bitand t property  64   64   IOT                  decode bitand t property  512   512   IOT OVERFLOW                  decode bitand t flags  536870912   536870912   IOT MAPPING   null    iot type          SYN TABLE OWNER OBJECT OWNER  o CREATED  o LAST DDL TIME  O GENERATED  O TEMPORARY  case when xt obj  is null then  N  else  Y  end EXTERNAL               FROM SYS Dba OBJECTS O  sys user synonyms syn sys tab  t  sys external tab  xt               WHERE  syn table owner   o owner               and    syn TABLE NAME   o object NAME               and    o object id   t obj                and   o object id   xt obj                   and    o object type    TABLE                and     INCLUDE SYNS   1    where     object name not in  select object name from recyclebin                           AND not object name like  BIN      Try to run this statement to get a full error messages indicating which table doesn t exists  which is equivalent to  is not visible due to missing access rights    SQL Developer will ask for values for SCHEMA and INCLUDE SYNS  Set SCHEMA to your username and INCLUDE SYNS to 0   SQL Developer 1 1 probably used a simpler query that worked with your access rights

For me  this wound up being a permissions issue    I solved the problem by creating a superuser role  CREATE ROLE root WITH SUPERUSER LOGIN PASSWORD  XXXXX    and then using that superuser account to connect to the database   This obviously won t be a viable solution in all situations

The answer about going under  Other Users  was close  but not nearly explicit enough  so I felt the need to add this answer  below    In Oracle  it will only show you tables that belong to schemas  databases in MS SQL Server  that are owned by the account you are logged in with   If the account owns has created nothing  you will see nothing  even if you have rights permissions to everything in the database    This is contrary to MS SQL Server Management Studio  where you can see anything you have rights on and the owner is always  dbo   barring some admin going in and changing it for some unforeseeable reason     The owner will be the only one who will see those tables under  Tables  in the tree  If you do not see them because you are not their owner  you will have to go under  Other Users  and expand each user until you find out who created owns that schema  if you do not know it  already   It will not matter if your account has permissions to the tables or not  you still have to go under  Other Users  and find that user that owns it to see it  under  Tables    One thing that can help you   when you write queries  you actually specify in the nomenclature who that owner is  ex   Select   from admin mytable   indicates that  admin  is the user that owns it  so you go under  Other Users   Admin  and expand  Tables  and there it is

I had this problem on my Mac  Fixed it by uninstalling it AND removing the  Users aa77686  sqldeveloper folder  Uninstalling without deleting that folder did not fix it  Then redownloaded and reinstalled  Started it up  added connections and it worked fine  Quit it  restarted it several times and it shows the tables  etc  correctly each time so far

The identity used to create the connection defines what tables you can see in Oracle  Did you provide different credentials when setting up the connection for the new version

User · Answer

3 1 didn t matter for me   It took  me a while  but I managed to find the 2 1 release to try that out here  http   www oracle com technetwork testcontent index21-ea1-095147 html  1 2 http   www oracle com technetwork testcontent index-archive12-101280 html  That doesn t work either though  still no tables so it looks like something with permission

User · Answer

The tables you are looking for are probably in a different schema   There are a couple of options   You can either click on Other Users in the tree under your connection  or right click on the connection and select Schema Browser and then select the desired schema
