Want to write sql queries online

Hi,
I want to write and test sql queries online. Because oracle database is too large I do not want to install it on my system. Is there any virtual environment where I can learn sql queries and test without installing it on my local machine?

SQL Fiddle apparently offers a test bed for various databases including Oracle 11gR2.
I haven't used it myself but it was highly recommended by SQL Indexing Tutorial | Use The Index, Luke! which is a good SQL performance tutorial.

Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database"

Hi, Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database" ?
When I use Connect Object Explorer, the "Connect to Server" dialog box which pops up has only 4 selections in the Server Type Drop Down List. They are Database Engine, Analysis Services, Reporting Services & Integration Services. I have read
somewhere that there should be a compact database option. but I do not see it.
What I would like to do is use free form SQL Queries against the tables in "SQL Server Compact 4.0 Local Database" .
Once I have validated these queries, then I will use them in my Visual Studio 2012 C#, ASP.NET application. I created the Local Database using Visual Studio 2012 for use by my application.
Thank you for your help..

Hello,
With SSMS 2005 we have had the Option to work with SQL CE database files, but not with higher Version of SSMS.
You can use the free SQL CE Toolbax instead; see

Want to practice SQL queries, do I need to download SQL editor

Hi All,
I have a doubt..
I want to practice SQL queries. for this, do I need to download SQL editor and Intall or If I download any Oracle version, does it will have SQL editor? please anyone answer my question.

I'm not sure how is it related to Peoplesoft, but if you installed an Oracle client on your client machine, then you have SQL*Plus or SQL Developer.

Want to execute SQL Queries from Textfile

I have a text file full of a bunch of sql queries, of the format:
select something1, something2
from someplace
select something3, something4
from someplace2
select something5, something6
from someplace3
I want to execute these queries one at a time and then after each one executes, I will do something with the resultset. Question is, how do I pull each query from the text file one at a time and execute? I was doing this by using java.util.Scanner and java.lang.StringBuilder where I would scan one line at a time and then check to see if the line is empty, otherwise I append the line to the StringBuilder. If the line is empty, I process whatever is stored in the StringBuilder. The problem with doing this is that it does not preserve the newline from the text file, so I get queries that look like:
"select something5, something6from someplace3"
which of course are invalid. Does anyone know a better way to build SQL queries / statements from a text file? How do I get the newline or carriage return character?

Just replace newline by space?

I want the list sql queries performed someone in one session based

V$SESSION V$SQLTEXT and audsid (taken from sys_context('USERENV','SESSIONID') ) are great .. session_id be generated by a trigger when the application logs on) but then uploading the list of sql queries made by that user (application) until they log off seems impossible.
I've tried creating triggers that check if V$SESSION changes with respect to an audsid number and sql_hash_value but it didn't work. I'm trying to work out why.
In the meantime I thought I'd post this to see if anyone else foudn another way.
I don't want to use sql trace that just gives load of info, I just want simple sql queries.
Auditting seemed a bit complicated, can that list ALL DML and DDL commands made by a user? if so how?
thanks
Bobby

quite right.
Oracle enterprise dedicated server 9.2.0.8 on solaris 10.
I just want to log all command DML and DDL, without stats or anything like that, simply a list, in a chronological order would be nice.
I found something called dbms_fga package but not sure if thats what I want. Seems I have to implement it on specific tables. which is not good if the application hasn't created the tables yet.
Thanks in advance.

SQL Queries in BO

Hi,
I'm working with Business Objects 3.1 Desktop and Webi. I want to type SQL Queries but I don't know how to do it. Is it possible to create queries in BO Desktop and Webi? If so, how can I do it? I'm not Administrator, I'm only a user.
Thanks in advance.

Hi,
Yes you can do by deski report.Create new report by based on Free hand SQL editor,create a connection for a database then paste sql in the editor and run.For more help login on the deski and go to the help tab and in the help you can find how to create report based on the Free hand SQL Editor.
In webi you can achieve this thing by to create one universe and insert derived table and paste the sql.Then create classes and objects and then create webi report based on the universe.You can not create webi report direct on the Free hand SQL.
In both of cases you have to rights to create report on Free Hand SQL editor or create universe.
Thanks,

Storing SQL queries in database itself.

I want to store SQL queries in 9i database itself so that I just need to pass the parameters from VB.NET front end and the query will execute. How can I do this?

Possibly make use of Stored packages/procedures/functions?
Back in 97/98 I had worked with VB (version 6 at that time) application for which I had written stored procedures to do exactly that... (except for select) VB application would pass parameter values to these procedures for doing inserts/updates/deletes. No application user was given direct insert/update/delete privileges.
Also I had triggers written for each of the table involved to keep footprint (user id and date/time) for last update/insert for each of the row.
I don't remember for sure if the application deleted rows from the DB. I think the application handled delete by actually updating a flag (active/inactive) again with a foot print so that you can track back the "deletes".

SQL queries inside html region

Hi,
I have html page in my application and i need to display result of the sql query inside this page. I would like to know if i can use the sql queries in html and if yes how can do that.
My query is select count(*) from Quote Letter master where service = 'Premier Support'
And i have similar queries like this which i would like to use in the html region.
Thank you,

My query is select count(*) from Quote Letter master where service = 'Premier Support'.For this you better use a page item and compute the items value using a page computation on on-load before header point. Then you can place the page items in a APEX region and also add any styling

Hi,
I dont know sql server 2005. But by observing it I feel you are generating sql dynamically based on condition inside the proc.
DECLARE
   TYPE EmpCurTyp IS REF CURSOR;
   emp_cv   EmpCurTyp;
   emp_rec employees%ROWTYPE;
   sql_stmt VARCHAR2(200);
   v_job   VARCHAR2(10) := 'ST_CLERK';
BEGIN
   sql_stmt := 'SELECT * FROM employees WHERE job_id = :j';
   OPEN emp_cv FOR sql_stmt USING v_job;
   LOOP
     FETCH emp_cv INTO emp_rec;
     EXIT WHEN emp_cv%NOTFOUND;
     DBMS_OUTPUT.PUT_LINE('Name: ' || emp_rec.last_name || ' Job Id: ' ||
                           emp_rec.job_id);
   END LOOP;
   CLOSE emp_cv;
END;something like this it will be. it is in oracle documentaion

The best place to store the queries, and HOW to store them depends on your architecture and on how your application is being used.
Is this a single-user application on a user's pc? Or is your application located on an application server in the middle-tier?
The queries should be stored where they will be used. Your queries should be stored in the tier where your application code will reside. On the client PC for a single-user app, on the application server for a 3-tier app and incorporated into stored procedures/functions/packages if part of a database app.
If your application is totally external to the database (e.g. a reporting app) then it doesn't make sense for you to become part of the database architecture. An org isn't going to let you create objects in the database to store your queries when your queries are not part of the database application. That puts the burden on them to backup your objects, restore them for your and provide support to you and your application.
What format to store the queries in is a different issue. A major criteria is the type of queries you are using and how they are used. Many apps that query the database cannot just use hard-coded queries that are never modified. Users need to be able to provide parameters (e.g. name, ID, state, etc) to select just the data that they want.
That means the base query itself may not even be valid syntax but needs to have a WHERE clause added. Prepared statements and queries that use bind variables ('WHERE ID = ?') are typically used for these.
One method of storage is to use Java property files that use name=value pairs. Using property files makes it easy to use Java to find a query by name and load it for you. Then your code would have functionality to modify the query to provide the parameter 'bind' values and execute it.
There are also frameworks available for handling database related functionality. There is no need for you to write your own libraries for this. I suggest you locate a suitable framework to use.

Generating XML from SQL queries and saving to a xml file?

Hi there,
I was wondering if somebody could help with regards to the following:
Generating XML from SQL queries and saving to a xml file?
We want to have a stored procedure(PL/SQL) that accepts an order number as an input parameter(the procedure
is accessed by our software on the client machine).
Using this order number we do a couple of SQL queries.
My first question: What would be our best option to convert the result of the
queries to xml?
Second Question: Once the XML has been generated, how do we save that XML to a file?
(The XML file is going to be saved on the file system of the server that
the database is running on.)
Now our procedure will also have a output parameter which returns the filename to us. eg. Order1001.xml
Our software on the client machine will then ftp this XML file(based on the output parameter[filename]) to
the client hard drive.
Any information would be greatly appreciated.
Thanking you,
Francois

BSP Application connection to SQL Express DB to execute SQL Queries

Hi There everyone,
I am not sure if I am posting this discussion in the correct section, but please try and help me out.
I have been tasked to write a BSP Application in the ABAP Workbench. The purpose of this application is to enable our Weighbridge operators to execute pre-defined SQL Queries by selecting certain criteria from the Application. The application is based on an HTML frontend which includes the Web Form (Input Fields, Submit buttons). We have 6 Weighbridges, each has its own HTML page in this application.
What I need to achieve is the following;
I need to know how I must setup the connection between the BSP Application and the SQL Express DB. Each Weighbridge has its own dedicated SQL Express instance + DB. These SQL Instances are not on the same host as where the BSP Application is located, I think the correct term is "External SQL Instances". Everything is on the same domain though.
What code would I need to add to the "OnInitialize" section in the BSP Application, to be able to establish the connection to the SQL Express database using Windows Authentication?
And what code would I need to attach to my submit buttons in the "OnInputProcessing" in the BSP Application, to execute a SQL Query to that DB and display the results in .CSV format back to the user?
I have attached 2 screenshots of what the BSP Application interface looks like. (This is what the user sees)
I am very new to creating BSP's, and I have never had to link to SQL from HTML / PHP before, so I basically have no knowledge of this.
Any help will be greatly appreciated.

Sorry for the late reply.
Yes, database is always available and online, not involved in Log Shipping or other things.
At the time of the connection failure I can find the following in the log of the application:
