Optimizing an SQL Query using Oracle SQL Developer

Hi ,
Currently i am using Oracle SQL Developer as my Database IDE .
Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
For example assume i am having a query as :
Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
Please share your ideas , thanks in advance .

1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.

  • Parameter passing to custom SQL query using PL/SQL FUNCTION

    Hi
    In order to pass a parameter to the query in custom folder of a business area I created a function and mapped it to the Custome query using Discoverer Desktop. There is no error in mapping as the system does not throw any error. When I am inputting the Parameter for the input values everytime the query doesnot return any rows.
    Can anybody help in this regard

    Hi,
    I need to take the request Id as input from the user and then fetch only the data pertaining to that requet Id. As a lot of complex joins are involved I need to pass request id as parameter to the custome folder.
    The package i greated:
    CREATE OR REPLACE PACKAGE SETPARAM
    AS
    param1 varchar2(25);
    param2 varchar2(25);
    FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER ;
    FUNCTION GET_PARAM1 RETURN varchar2;
    END SETPARAM;
    CREATE OR REPLACE PACKAGE BODY SETPARAM AS
    FUNCTION SET_PARAM1(p1 IN varchar2) RETURN NUMBER IS
    BEGIN
    fnd_client_info.set_org_context('138');

    RETURN 1;
    END;
    FUNCTION GET_PARAM1 RETURN varchar2 AS
    BEGIN
    RETURN param1;
    END;
    END SETPARAM;
    I registered the set_param1 function as a pl/sql function in discoverer admin.
    This function is called on the condition associated with the parameter in Discoverer Desktop when i run the report.
    In the custom folder query i have this piece in the where clause
    WHERE tnfo.request_id = NVL(APPS.SETPARAM.GET_PARAM1,7383588)
    And everytime i get the data pertaining to request id =7383588,
    Please suggest where i went wrong

  • Getting the schema using Oracle SQL Developer 1.5.1

    I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
    in the below format.
    Table Name: XXXXXXXXX
    Table Space Name: XXXXXXXXXXXXXXX
    Structure :
    Field Name Data Type Size
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx

    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Sequence Number:
    Xxxxxxxxxxxxxxxx
    Triggers:
    Xxxxxxxxxxxxxxxxxx
    I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
    I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
    In the Create Report Dialog, I chose the option Script for Value of Style.
    In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
    00933. 00000 - SQL command not properly ended" Cause:    Action: "
    I end the first query with a semi colon, but it does not work.
    The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
    Am I doing something wrong? Can someone please advise on how to get the information I need?
    Thanks a lot.

    You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
    Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.

  • Accessing MySQL InnoDB tables via JDBC using Oracle SQL Developer

    I had posted a problem in the Oracle SQL Developer forum with how that application (v1.1) accesses MySQL InnoDB tables and someone replied that the "[data migration] team created the integration with MySQL", so I am posting here in hopes of learning more about the problem.
    Here's a summary:
    When I use Oracle SQL Developer to query MySQL InnoDB tables, I need to issue a "commit" before I do each query to ensure that I am getting current results. Otherwise, it appears to be using a snapshot as-of the last commit. Is this a problem with SQL Developer, or a JDBC configuration, or MySQL problem even?

  • How to use Oracle SQL Developer 4.0 to connect to Ms Access file with .accdb extension

    Hi all,

    Thank you very much in advance

    That MS Access driver is 64-bit, I think.  If SQL Developer, or JDK is 32-bit you need to use the 32-bit driver.   You can see if you have a 32-bit driver installed using  c:\windows\system32\odbcadm32.exe

  • Issues using Oracle SQL server Developer migration work bench

    Hi all,
    We are trying to migrate the application databases from SQL server 2000 to Oracle 10g using Oracle SQL Developer 1.2.1.32.13:
    Following is the list of issues that we faced while trying out this migration on dev environment.
    1. The data migration was successful for only around 90 tables out of the total 166 tables present. No error message was logged for the rest of the tables but still it was completed.
    2. Some of the tables which had got the data inserted did not have the full data. Only some of the rows were inserted for these tables. Error message was logged only for few of the rows and not all.
    3. Few error messages were logged which said problems about “Inserting ' ' into column <tablename>.<columnname>”. There was no such constraint in the target database that the particular column can not be null or can not have only a space. Please check the logs for the same error messages.
    4. The status box at the end of migration had shown only 3 errors.
    5. The total data for migration was around 500MB. The time taken for migration was around 75 minutes. Are there any optimization techniques that will improve the performance?
    Please note that there were no Foreign Key references for the source schema or target schema.
    Any pointers/info/resolutions related to above mentioned issues will be much useful for us.
    Thanks,

    Hi Adam,
    There are 2 sets of scripts created for you.
    1) For SQL Servers BCP to dump out the data to dat files
    2) For Oracles SQL*Loader to load the dat files
    You run the SQL Server BCP scripts on the machine with SQL Server.
    The dat files will be dumped out on that server.
    You can then move the dat files to your Oracle server.
    Then run the Oracle SQL*Loader scripts to load the dat files into Oracle.
    Give it a go and follow the doc and viewlets.
    Your Questions:
    So the datadump from the source location would be saved on my local disk?it will be saved on the same machine you run the bcp scripts from. Usually the same machine SQL Server is on, because you require SQL Server BCP tool.
    So once it is migrated to the destination database will that dump be created automatically? Or do I need to modify the script to take care of this?I dont know what you mean by this, hopefully above clears things up.
    The only modifications you need to make to the scripts are adding in the databasename username password servername. These are outlined in the scripts themselves. I would want to do something fancy like dump the dat files to a different directory, then you can modify the scripts, but you should understand what they do first.
    Most people would have 500MB of space on their discs , so I can see the problem creating these dat files . The same goes for your 30 GB database.
    I hope this helps, but as always you wont get a good idea of how it works until you give it a go.
    Regards,
    Dermot.

    There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
    #SetJavaHome ../../jdk

    C:\> imp user/password@connectionB file=mytable.dmp full=y

  • How to insert data from *.dmp file to  oracle 11g using Oracle SQL Develope

    hi
    i backup my database using PL/SQL developer and made *.dmp file
    how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer 2.1.1.64
    and how to make *.dmp file from sql*plus ?
    thanks in advance

    Pl/Sql developer has a config window, there you choose the exec to do the import/export.
    Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
    Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer 2.1.1.64. If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.

  • How to Suppress The Output of a SQL Query In Oracle 11gR2

    Hi Friends,
    I am using oracle version 11.2.0.1, I have set a cronjob which will run on every 15 minutes and give us a log file mentioning the execution time taken for that SQL query:-
    For example:
    SQL> set timing on;
    SQL> SELECT objProp FROM aradmin.arschema WHERE (schemaId = 175);
    OBJPROP+

    Elapsed: 00:00:00.00
    The above query will return the output as well as the time taken for execution of the query. I want to suppress the output of the query and only want the time taken to be printed. Is it possible by set commands. I have marked the output as bold and made it Italic.
    Please help me at the earliest.

    How would that even be useful?
    A query from a tool such as sql*plus is STILL going to send the output to the client and the client. You can keep sql*plus from actually displaying the data by setting autotrace to trace only.
    But that TIME TAKEN is still going to include the network time it takes to send ALL rows that the query returns across the network.
    That time is NOT the same as the actual execution time of the query. So unless you are trying to determine how long it takes to send the data over the network your 'timing' method is rather flawed.
    Why don't you tell us WHAT PROBLEM you are trying to solve so we can help you solve it?
