ODP.NET :: Connection Open But No Tables Views Or Procedures?
Oct 5, 2012
Going through my first attempt ever to connect to a Oracle database with a .Net application. Using Visual Studio 2012, I have downloaded and installed the latest version of odp.net, actually both the 32 and 64bit versions.
Application is targeting the 4.5 Framework, Latest version of Entity Framework installed (but not important I think at this point) Added a reference in my project to the Oracle Data Provider ( tried with both 2.0 and 4.0 )
Created a connection string with EZ Connect, stored in web.config file. I have tried 2 different projects to use EF and one without. Trying to create a edmx or using a datasource adapter brings up the connection wizard or prompts to use the existing one, but no matter what I try, there are no tables, views or procedures listed.
From Server Explorer, I can open the Data Connections and verify that the connection to the Oracle database is Open. During the Connection Wizard, there were no errors, and all the databases available were listed. Yet, connecting to and opening the connection to this specific database or anyone for that matter no tables, views or procedures are listed.
Our Oracle Application & Database 10.2.0.4 is installed on Windows 2003 R2 32 bit and our development team trying to access this database from windows 2008 64 bit.where we have the Oracle client 10g installed for 64bit but when they are trying to access the instance they are getting below error
I have Oracle 11g XE and Toad installed on Windows 7 64-bit machine. I am able to connect to database from Oracle's SQLPLUS. But when connecting from TOAD i am getting ora-06413 connection not open error.
Let us say there is an oracle table A. How do i find out what stored procedures/packages/views are using this table A.
Reason to know: When some DDL changes happen on table A, how do i know what are the impacted sp/pkg/views which should also be modified. Is there any query with which i can find this?
I am in the task of clean up of tables. I need to find the list unused tables and procedures. Is there any way where i can find when was the last time the table queried?
Give sql query to find the list of unused tables and procedures.
"Create a view named vuPassFailRate that will show the pass rate and fail rates of each test."
I have a table named Test_ID containing the following columns:
TEST_ID TEST_NAME PASSING_GRADE
And another table named Test_History containing the following columns:
TEST_ID STUDENT_ID SCORE
I'm assuming i have to create an inline view, and to work out the pass/fail rates i need to do something along the lines of (For pass rate) Where SCORE is greater than or equal to PASSING_GRADE, and TEST_ID equals TEST_ID, divide by a count of SCORE and multiply by 100. I just cant work out the nested select statements, and work out the formula using two columns in two tables.
I have been staring at this problem for so long now i cant see the wood for the trees.

i just posted another topic where i heard about external table and i had a few questions concerning them. I thought it was best to create a new topic than to continue on the other one...
I noticed that to create an external table the CTL is like this: CREATE TABLE emp_load (FIELDS description) ORGANIZATION EXTERNAL (TYPE ORACLE_LOADER DEFAULT DIRECTORY ext_tab_dir ACCESS PARAMETERS (RECORDS FIXED 62 FIELDS (employee_number CHAR(2),
[Code]...
1) This creates an external table, but, is it possible to Create a normal table in a CTL file? For physical tables, the table has to exist right?
2) if you create a view linked to 2 external tables and if the CSV files are updated each day, the external tables will be updated automatically, and the view will be updated as well?
3) Can't there be any synchronisation problems?
4) What happens if a select request (or someone requests on the view) while the CSV file is being updated?
5) Is there anyway you can protect the accesses from those tables/views when the CSVs are being updated?
6) Is it possible to create an index on these sort of tables?
7) Is it possible to index a view?
8) Are external tables visible on a tool like sql developper?
Is it possible to create trigger on the various tables and views exists (i.e. dynamic performance views) in data dictionary, when ever any DML operations performs by Oracle it self?
I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name AS SELECT EMPLID, EMPL_NAME FROM VEMPDATA@REMOTEDB WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
I am removing sal column from table tab_emp; i want to check whether any materialized view or view using this column by querying using data dictionary :- if i use like condition against query column of all_mviews it is throwing error sicne it is long data type. is there a way to search it without creating any function and use it in a query.
I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication 1) create interim tables with similar structure as the materialized views 2) transfer all data from the materialized views to the interim tables 4) script out the materialized views structure and add in on prebuilt table option in the scripts 5) drop the materialized views 6) rename the interim tables with the same name as the materialized views 7) run the scripts to create the materialized views with on prebuilt table option 8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?
I want to create a wallet on RAC setup.I have two node setup.I have created the wallet directory under shared folder /u01/oradata/$ORACLE_SID/wallet
I am Unable to open wallet.I tried this using the below command
SQL> alter system set encryption key identified by "aryabhat"; alter system set encryption key identified by "aryabhat" * ERROR at line 1: ORA-28353: failed to open wallet
I could execute a package for eg if i had a package with procedures related to statistics and i run them each night, could i just do an exec on the package and it would run all those procedures??
Its not possible but i could call each procedure from ONE procedure
whats the best way to modify a table via a procedure for example if i have a table with records: id, fn, ln, address, tel, dob
how would i go about creating a procedure that modifies a record. The problem is what param needs to go in? i could certainly have different procedures that modify different things like one for modifying tel, one for modifying address, but is there a way to combine it all into ONE procedure so that if user wanted he could put in exec modifyTable(2, 099898787) to modify tel and then modifyTable(2, 'a new address') to modify address... ?
we are doing a performance tuning on a large database. Our main aim is to capture all the packages/procedures/view that are running on database. Below given is the format we have prepared
Eg: SPIdSP_Name CPU TimeI/OLine Executed 1Emp_AllDetails221 1Emp_AllDetails582 1Emp_AllDetails25103
[code]...
Requirement:Write an Procedure that captures the above given information in the background of database and stores the information in a table.write the procedure to capture the above given information.
I come from a Microsoft SQL background and am having trouble adjusting to the PL/SQL syntax. I'd like to build this up to pass back a certain value back into a web form.
IF (SELECT COUNT(*) FROM EXCURSION WHERE EXCURSION_ID = 75)= 1 THEN DBMS_OUTPUT.PUT_LINE 'True'; ELSE DBMS_OUTPUT.PUT_LINE 'False'; END IF;
I'm having trouble writing values out at the moment
I am using for writing text files data to database. The problem here is let us assume there are 6 records in text file and if there is a problem at 2nd record, the later records are not getting inserted.
CREATE OR REPLACE PROCEDURE PROC1 IS temp varchar2(500); tmp_name varchar2(5); tmp_no varchar2(4); . BEGIN WHILE NOT end_of_file LOOP
IF i = 18 THEN tmp_no := temp; END IF;
IF i = 21 THEN tmp_name := temp; END IF;
END LOOP; END; /If i=18 and temp = '12345' here, then tmp_no := temp; won't work (tmp_no varchar2(4);) Similarly, If i=21 and temp = 'ABCDEFG' here, then tmp_name := temp; won't work (tmp_name varchar2(5));
how to handle this through EXCEPTIONS so that even if there is a problem with 1 record, while loop remain working for further records..
By referring through net I have written the following PCK file. I have installed my Oracle 11g database in VirtualBox(Win XP). I can able to select the tables using query from the host(Windows 7)
CREATE OR REPLACE PACKAGE APEX_SYS_PCK AS TYPE refcursortype IS REF cursor PROCEDURE GET_USER_DETAILS( D1 OUT refcursortype, P_USER IN VARCHAR2, P_PASS IN VARCHAR2);END APEX_SYS_PCK; / CREATE OR REPLACE PACKAGE BODY APEX_SYS_PCKAS PROCEDURE GET_USER_DETAILS( D1 OUT refcursortype, P_USER IN VARCHAR2, P_PASS IN VARCHAR2) IS BEGIN OPEN D1 FOR SELECT * FROM APEX.PERSONS; END GET_USER_DETAILS; END APEX_SYS_PCK;/
When I try to run the script I am getting the following error. How to solve this problem?
Project: sqldev.temp:/IdeConnections%23vAPEX.jprF:PACKAGESAPEX_SYS_PCK.sqlError: PL/SQL: Compilation unit analysis terminatedError(1,14): PLS-00905: object APEX.APEX_SYS_PCK is invalidError(1,14): PLS-00304: cannot compile body of 'APEX_SYS_PCK' without its specification
