Is that something that can be done in Oracle in the same way?
Do you use another approach?
please advice

How to write this sql query to oracle

Hi sir,
i am using one query in my sql stored procedure that is:
select @maxtime=CONVERT(Time,Out_Time+DATEADD(n,60,0)) from shift where Shift_Code = @ShiftCode
so here i am getting this value 01/01/1900 12:00 AM
the same i used in oracle my query is :
to_char(Out_Time,'1900-01-01' + 0/(24*60),'DD/MM/YYYY HH:MI AM')
INTO v_maxtime
FROM shift
WHERE Shift_Code = v_ShiftCode;
but getting error that is: Encountered the symbol INTO when expecting one of the following :=(%;
am i doing any thing wrong.
thanks

The error you're getting is a syntax error. In this case because you've mangled the TO_CHAR syntax. Alas I cannot give you the correct version because I cannot unpick what you're trying to do with that statement.
It would be easier if you expalined what business logic you're trying to implement instead of asking us to interpret a piece of shonky SQL.It's yet another of the OP's questions about how to do DATEs in Oracle (so many threads it can get very confusing - even though the OP has been asked to stick to one thread!).
The code looks like it's based on the answer I gave here:

but clearly he doesn't understand the basic syntax of Oracle or the datatypes he's using. Sometimes you just have to give up... (I know I have)

How can I write this SQL?

the statement have the question:
     stxh-tdname length 70
     itab-vbeln       length 10
select tdobject into table it_stxh
    from stxh
    for all entries in itab
    where ( tdid = 'Z006' and tdspras = 'E'      and tdname+0(10) = itab-vbeln and tdobject = 'VBBK' ).
tdname+0(10) = itab-vbeln ???

When you define the first Internal Table ITAB, define vbeln as the same type of stxh-tdname.
Eg.
data: begin of itab occurs 0,
          vbeln like STXH-TDNAME,
          erdat like vbak-erdat,
          end of itab.
START-OF-SELECTION.
Select VBELN
          ERDAT
from vbak
into CORRSPONDING FIELDS of table itab.
Then you can directly use this ITAB in the next query
select tdobject into table it_stxh
from stxh
for all entries in itab
where ( tdid = 'Z006' and tdspras = 'E' and tdname = itab-vbeln
and tdobject = 'VBBK' ).
Pls reward it if it is useful.

How to get the correct sql command in oracle?

Hi sir,
i am using this query in sql that is :
SELECT C.*,ISNULL(P.Comp_Name,'') + ' (' + ISNULL(P.Comp_ID,'') + ')' Parent FROM Comp_Master C LEFT JOIN Comp_Master P ON C.Parent_ID = P.Comp_ID Where C.Comp_ID='004'
so i am getting in parent column value like this: "PARIS GROUP (001)"
but the same command i converted in sql developer that is:
SELECT C.* ,NVL(P.Comp_Name, ' ') || ' (' || NVL(P.Comp_ID, ' ') || ')' as Parent FROM Comp_Master C LEFT JOIN Comp_Master P ON C.Parent_ID = P.Comp_ID WHERE C.Comp_ID ='004'
but not getting in parent column value its coming only ( )
help me.

Welcome to Oracle.
It has manuals.
http://tahiti.oracle.com/
Choose your version, which you continue to keep a mystery
E.g.
http://www.oracle.com/pls/db112/homepage
Including Oracle SQL syntax
http://docs.oracle.com/cd/E11882_01/server.112/e26088/toc.htm
Which you will find useful since Oracle does not run Microsoft SQL as you continue to find over and over again.
And there is a 2 day getting started as a developer guide, which you appear to desperately need,
http://docs.oracle.com/cd/E11882_01/appdev.112/e10766/toc.htm
If you have any specific questions about anything you read in there, come back in a couple of days after you have finished reading them.

How to write this SQL query

We have a table, the structure as below: (I put a blank row in the middle to make it clear)
Product_ID     Retailer     Retail_Price
1001          A          1.2
1001          B          1.5
1001          C          1.4
1002          B          2.0
1002          C          2.1
1002          E          1.8
1002          F          2.0
1003          A          1.7
1003          C          1.5
Basically we use the table to compare the retail price for different retailers in terms of different products. My customer asked me to give a report based on above table but only shows the retail prices which contain retailer A.
For example, on above table I need to give a report like below:
Product_ID     Retailer     Retail_Price
1001          A          1.2
1001          B          1.5
1001          C          1.4
1003          A          1.7
1003          C          1.5
Can anybody give some ideas on how I should write a SQL to achieve this.
Many thanks!

How execute pl/sql command from Oracle ADF Business Components

can't find examples for how execute pl/sql command from Oracle ADF Business Components and how call pl/sql package procedure from ADF Business Components.
insert,update,delete rows in view object instance cache is good but if i must do some complex operations while insert,update,delete rows..it's more better for me to call
pl/sql procedure from oracle db.Am i wrong ????

Roman,
this should be similar to how it worked in JDeveloper 9.0.3. hava a look at <JDev903 Home>\BC4J\samples\StoredProc for a code example.

How can I write a SQL statement which checks if a table exists?

How can I write a SQL statement which tells me whether a table exists?

execute an sql query: select * from <tablename>
catch the exception n check whether the erroe code
matches the one that occurs for table doesn't exist
that's itHow is your answer any different from the one given in the first reply?
It isn't.
As WorkForFood says DatabaseMetaData has a bunch of methods for getting information about tables but this is more useful when you don't know the names of any of the tables.. it sounds like you do so I would concur SELECT from table is probably the quickest way to go. If it helps the Xopen error should be either S1000 or 42S01 (I think) but I would try and see if there is a specific vendor code for table not found/not exists error and check for that.

List v = new Vector() how can i write this ?

List v = new Vector() how can i write this ?
vector does not 'extends' List rather it 'implements' only ......so how can write this way ? ( polymorphism applies only for 'extends' ).

my question in a simple way is :
List some_list extends Vector
No, List is an interface; Vector is a concrete class. Read the javadocs.
Vector implements List
>
AND
List some_list implements Vector
are these two same in behaviour
our apart from theoretical differences ?thanks
Interfaces don't have any implementation; they're pure method signatures. When a concrete class implements an interface, it makes a promise that says "I will provide implementations for exactly these methods. Any client can call a method from the interface and I will do something 'sensible' if I'm written correctly."
From the point of view of static and dynamic types, there's no difference between interfaces and classes.
C++ has interfaces, too - they're classes with all pure virtual methods. If you understand how C++ works, the concept shouldn't be hard.
ArrayList is preferred precisely because it isn't synchronized by default. (You can always make it so using java.util.Collections if you wish later on.) If you don't need synchronization, why pay the performance penalty?

How do I write this as a loop?

How do I write this code to function as follows.
When btn1 is clicked, SenderLoad should be "clay" AND when btn2 is clicked, SenderLoad should be "iron", etc...
var mgB:Array = [btn1, btn2, btn3, btn4];
var mgBW:Array = ["clay", "iron", "cotton", "leather"];
var SenderLoad:LoadVars = new LoadVars();
var ReceLoad:LoadVars = new LoadVars();
var mgNum:Number=0;
for (i=0; i<mgBW.length ; i++){
mgBW[i].onRelease = function () {
mgNum++
SenderLoad.word = mgB[mgNum];
SenderLoad.sendAndLoad("http://www.web.com/my.php",ReceLoad,"POST");
ReceLoad.onData = function(src) {
var messageA:Array = src.split(",,,");
ldrB2.html=true;
for(var i:Number=0; i<messageA.length; i++){
           var a:Array=messageA[i].split(",,");
   ldrB1.htmlText +=a[0];
   ldrB2.htmlText +=a[1];

if you want different words in different colors you can use:
ldrB1.html=true;
ldrB1.text = formatF("REJECT",0xff0000,ldrB1)
ldrB1.text = formatF("ACCEPT",0x000000,ldrB1);
ldrB1.text = "formatF("BANNED",0xc0c0c0,ldrB1);
function formatF(s:String, col:Number, tf:TextField):Void {
if(tf.text.indexOf(s)==-1){
return;
    tfor.color = col;
    var startindex:Number = 0;
    while (startindex>-1 && startindex<tf.text.length-1) {
        var bindex:Number = tf.text.indexOf(s, startindex);
        var eindex:Number = bindex+s.length;
        tf.setTextFormat(bindex,eindex,tfor);
        startindex = eindex;
var tfor:TextFormat = new TextFormat();

Well, at least you tried and got some of it right.
I think this should do what you want, but my C is rusty. Is the increment performed before or after the loop executes? If it's after, then I believe the loop should iterate 11 times, not 10.
In any case, you should note that for a literal translation, you would need to add a sequence structure to guarantee that Y was written to only after the inner loop finished because of the way data-flow works.. Also, note that controls and indicators in LabVIEW are not equivalent to variables. They can be used as such, but they usually should not be.
Another point about this is that you probably want to use the correct data type - the orange terminals are floating point indicators (of double precision, in this case) and you want integers.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.
Try to take over the world!

How to connect to a Sql server from Oracle using db link

Hi All,
Does anybody have any idea about how to connect to a sql server from oracle database using db link to syncronize the data? I need to pull the data from Sql server table to Oracle tables and relay messages back to the sql server.
Thank you,
Praveen.

we have 2 products - DG4MSQL and DG4ODBC.
DG4ODBC is for free and requires a 3rd party ODBC driver and it can connect to any 3rd party database as long as you use a suitable ODBC driver
DG4MSQL is more powerfull as it is designed for MS SQL Server databases and it supports many functions it can directly map to SQL Server equivalents - it can also call remote procedures or participtae in distributed transactions. Please be aware DG4MSQL requires a license - it is not for free.
Check out Metalink and you'll find notes how to configure both products.
