How to test the select statement.

Hi All,
How to test the select statement.
Is there any Oracle sqlplus  or toad kind of tool to  test the query.
thanks
siva

Use SQL Trace (ST05) and choose 'Explain one SQL Request'. Enter your SQL command as it should be executed in the underlying database. e.g. if the db is Oracle, the statement should be entered as:
SELECT matnr,werks,lvorm,dispo
FROM marc
WHERE mandt = :a AND
             matnr = :b AND
             werks = :c
In the above :a, :b and :c are place holders for the actual comparison values. You dont have to enter those values. When you choose 'Explain' button, you will find the 'Execution Plan'. The important parameter which denotes the efficiency of the SQL statement is the 'Cost'. The cost should be as low as possible. The table access should be through INDEX UNIQUE SCAN. If you get a FULL TABLE SCAN and higher cost, you need to fine-tune your statement by modifying the where clause.
If you dont know Oracle SQL statements, execute the program in trace mode and go to the trace and you will find the underlying SQL statements issued to the database.

  • How to find the select statement has written all selected values into text

    Hi,
    I am using form6i. i am selecting a set of values from database tables based upon some user parameters and writing into the text file using Text_io.put_line . In this case how we can make sure that the text fille contains all the data what we are selected from selected statement. somebody told that there might be chances of aborting of data while writing into the text file. is there any way to fild out the selected statements has written all the selected fields and corresponding output into the .txt file.
    Please suggest me.

    somebody told that there might be chances of aborting of data while writing into the text fileWhat kind of "chance" does that somebody refer to?
    If you want to verify if the number of records (lines) in the file matches the number of records from the cursor, you could re-open the written file in read-mode and count the number of lines by reading one by one, then compare the number of lines with the number of records from the cursor.

  • How to test the update statement in SQLJ - Im lost and cant figure it out!

    Hi Im wondering on the sytax of this logic.
    //Execute an update on a table
    #sql {update mytable set name = :test where today = sysdate };
    //This is where im lost. how to test if the record is not found
    if (record not found for update){
    #sql {insert mytable set name = :test where today = sysdate };
    I dont want to do a select count(*) and based on the value go to update or insert.
    Does anyone know how to do it?
    Thanks so much

    If Software Update is offering the update then it would be compatible with your model.  Unfortunately, you haven't provided us with any information on your hardware that would enable us to determine if it really is too old.
    If you really wish to disable the update alert then the next time Software Update opens, select the update in the list then select "Ignore update" from SU's Update menu.

    Hi,
    SELECT KUNNR

               PSTLZ
               LAND1

    Here I am getting records only when WHERE KUNNR = IT_LIKP-KUNNR AND

    But I need the records for both when KUNNR = IT_LIKP-KUNNR
                                 And     KUNNR = IT_LIKP-KUNAG.
    Can you suggest me the best logic.
    Thanks.

    Hi Suresh,
    Use the following code.
    Loop at it_likp.
    if it_likp-kunnr <> ' '.
    select name1 stras ort01 pstlz land1 into corresponing field of table it_kna1
             from kna1

    select name1 stras ort01 pstlz land1 into corresponing field of table it_kna1

             where kunnr = IT_LIKP-KUNNR

    endloop.
    hOPE THIS WILL WORK FINE.

  • How to speed a select statement with the NOT EXISTS where condition ?

    Hi all,
    I created a view : create or replace view view_name as select * from table_1,table_2 where join_condition and some conditions.
    Now I have added in the view "where" clause two NOT EXISTS conditions based on one another different table respectively.
    Before I added these two conditions the response time was fast ; but after I added these two conditions then the response time deteriorated.
    So how to optimize the select statement ? Hints and so on ...

  • Restricting records in the select statement

    Hi,
    I have one requirement where in i need to restrict my select statement to get only 250 records in the output table.

    Could anyone let me know how to write the select statement.
    Regards,

    restric the first select using up to 250.
    sort the i_ekko by vendor name.
    ex: sort i_ekko by lifnr.
    use second select statement here.

  • How can I call a Page Process from the Select statement for Report Page

    I'm able to call a javascript using the below:
    img src="#IMAGE_PREFIX#add2.gif" border="0" alt="Icon 4" onClick="javascript:add_connect1('||CPORT.ID||')"
    But Now,
    I'd like to accomplish (2) New things:
    1. instead of using,....... onClick="javascript:add_connect1,
    I'd like to call a Page Process, onClick=
    2. I'd like to be able to call two different processes onClick.
    a. onClick="javascript:passBack('||ID||')"
    b. onClick= <Please see my question #1 above>
    Can someone please help me with the syntax for this,
    If indeed it can even be done?
    Thanks- Gary

    Greg.
    It seems that my situation is the one you describe in you second paragraph, where you mention:
    you could then add the ID column value as a parameter to the javascript functionBut,
    I do not know how to reference the variable in my javascript nor how to use it in my on-demand process.
    If you can hellp me past this last little bump, then I think I will be able to use these skills in Sooo many different areas of my design.
    Here's what I've got so far:
    A. In the select statement I identify the javascript as:
    onClick="javascript:connect_port('<font color=blue>''||ID||''</font>')";
    B. In my javascript I have this:
    <script language="JavaScript" type="text/javascript">
    function connect_port(ID)
    var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=CONNECT_PORT',0);
    gReturn = get.get();
    get = null;
    </script>
    C. In my on demand function I have this:
    BEGIN
    INSERT INTO CCONNECTIONS_B
    BLDG_ID,CLST_ID,PORT_ID,STRAND_ID
    ) VALUES
    :P2004_BLDG_ID,:P2004_CLST_ID,:P2004_PORT_ID,:P2004_STRAND_ID1
    END;
    You can see that I dont know how to use the value for 'ID' in either the javascript or the On-Process function.
    If you can help me out with this one, Then I can imitate it for the rest.

  • Case sensitive statement in the select-statement

    Hi All,
    i have a table in the abap-dictionary filled with names...when i try to select them with the select-statement with condition:
    table-name_column like 'some_name'
    I have encountered some problems...the inquiry is case-sensitive. What i want to do is to read the value from the abap-dictionary table uppercase or lowercase and compare it with the needed value also translated in uppercase or lowercase.
    The only idea i have is to select all values of the dictionary table into an internal table and to translate the values there in uppercase or lowercase and then to loop trough it. But this approach would cost a lot of performance.
    Do someone has an other proposal?

    check...
    Select statement
    It would be difficult , because it is based on how data is stored in the data base , now consider the scenario of the system i am using , we can material description as 'test' or 'TEST' , 'Test' .
    If in your system there are only stored in either caps or small the you can perform the select twice .
    But i myself dont find it to be such a good solution , but you can give it a try
    There is one more solution specific to material description ,and that is in the table MAKT there is a field MAKTG , which stored the description in uppercase , so for this you can first convert the description to uppercase and then perform select on this field

  • In BI how to filter the selection options based on inputs on top field

    Hi Friends,
    In BI, How to filter the selection options based on inputs on top field.
    The system should automatically filter the lower level drop downs based on the selection of a higher level.
    For e.g. :
    If a user selects a Country then the States drop down should only display the State's belongs to the Country. Similarly when a State is selected, the District drop down should display only those District's belongs to the State.
    Thanks in Advance.

  • How to execute a SELECT statement  in java??

    Hello !!
    In my java program , i need to delete a record of number X, so
    i accept the number X from the keyboard
    Then before deleting it
    i want the program to show me the name, age of the record which has the number X
    How to do this

    hello kylas
    actually i didnt get why this program example?? wats
    its executing ??? Look at reply #3 in your other thread:
    http://forum.java.sun.com/thread.jspa?threadID=713289&messageID=4126346
    Notice the similarity? You've now asked "How to delete a record in Java" and "how to execute a select statement in java". You may have noticed that, aside from the SQL and the call to execute and executeUpdate (for delete) it's the same code. This is because you don't so much do these things in Java, you do them in SQL. The Java code simply asks the Driver to execute whatever SQL you write. So, I really hope your next post isn't "how do I execute an UPDATE statement in Java".
