Conversion of SQL worksheet.

Hello

If I sent someone a microsoft excel spreadsheet, the chances that you would be able to convert in SQL if I named a few tables and columns that were to be used are there?

Please let me know,

Thank you SM.

If your excel workbook is formatted so that you have a 'table' by the worksheet contained in it and the first row on the worksheet defines column names and the following lines are the data, then you can treat the workbook as an external database using the ODBC Excel driver.

Set up:

1- Go to Control Panel>Administrative Tools>Data Sources (ODBC)>System DSN and create a data source with appropriate driver. Name it EXCL. 

2- In %ORACLE_HOME%\Network\Admin\Tnsnames.ora fie add entry:

EXCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.12.0.24)(PORT = 1521))
)
(CONNECT_DATA =
(SID = EXCL)
)
(HS = OK)
)

Here SID is the name of data source that you have just created.

3- In %ORACLE_HOME%\Network\Admin\Listener.ora file add:

(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = )
(ORACLE_HOME = )
)

under SID_LIST_LISTENER like:

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\ORA9DB)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORA9DB)
(ORACLE_HOME = d:\ORA9DB)
(SID_NAME = ORA9DB)
)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = EXCL)
(ORACLE_HOME = D:\ora9db)
) ) 

Dont forget to reload the listener 

c:\> lsnrctl reload

4- In %ORACLE_HOME%\hs\admin create init.ora. For our sid EXCL we create file initexcl.ora.

In this file set following two parameters:

HS_FDS_CONNECT_INFO = excl
HS_FDS_TRACE_LEVEL = 0

5- Now connect to Oracle database and create database link with following command:

SQL> CREATE DATABASE LINK excl
2 USING 'excl'
3 /

Database link created.

Now you can perform query against this database like you would for any remote database.
SQL> SELECT table_name FROM all_tables@excl;

TABLE_NAME
------------------------------
DEPT
EMP

  • How to get line numbers to display on the SQL worksheet?

    Dear Forum,

    I learn the SQL Developer.  I use it in my work and school.  At school, when I enter a query in the SQL worksheet, line numbers show in a column to the left of the editing area.  In my work, no line number.  I'm working on a fairly long query at my work, and the line numbers would be useful.

    I looked at tools / preferences / settings for the Code Editor, but do not find a setting for line numbers.  I looked at the other tabs in preferences and found nothing that looked useful.

    I have looked at all of the choices on the display list, but can't find anything on line numbers.

    Am I missing something obvious?  Line numbers is also available?  If so, how?

    I looked at various hits "line number" in this forum, but I've not found anything exactly the point.

  • How to perform the procedure in the SQL worksheet?

    Hi, anyone knows, how I can execute procedure here?

    I try to EXEC sec_roles, EXEC security_admin.sec_roles, EXECUTE - there's a SQL statement error. When I use the CALL - there is no such procedure (I have execute privileges).

    Although in SQLPlus EXEC works, but there are problems with the standard SQL commands (each of them '2' returns any content is).

    Any ideas?

    Concerning
    Krzysztof

    EXEC procedure (parameters) is a plu sql (and some others) shortcut for

    BEGIN
   procedure(parameters);
END;

    So try that and then pressing / on anything in the sql worksheet that makes a statement in execution.

    Note that if your procedure has defined parameters as OUT or IN OUT, you need to provide a variable to accept the returned values.

  • Formatting characters in the SQL worksheet in the version 2.1.1.64

    Hello

    Using the version 2.1.1.64

    When I type SQL in the SQL worksheet calculation is to show formatting characters - for example all the spaces display as a light gray and a newline character appears at the end of each line.

    Formatting characters displayed not initially when I started to use this version. I don't know how this setting is enabled, but there doesn't seem to be a preferences setting to turn it off. Any ideas?

  • 1Z0-146 and SQL worksheet

    I picked up a practical test of uCertify (the test of practice only legitimate 1z0-146 so far), and he has questions on the use of SQL worksheet.
    Must I dismiss these, since they appear nowhere on the requirements for the test (or maybe they fit under "Introduction to PL/SQL"? ""), or should I start using it because of the test?
    I never use sheet SQL calculation, but always on a SQL * the command-line with my files in a trainer Plus project.

    I've glanced through the cover of uCertify page previously and noted some serious inaccuracies... in fact my current visit was to show a little less. These things could be in my imagination. For 1z0 - 047 they go on iSQLPLUS orders...

    I'm sure that 1z0-146 is PL/SQL tool independent, so these questions are probably not relevant.

    UCertify generally seem to be fast on the market, generally of lower quality and posibly coverage is not comprehensive but perhaps useful for a guarantee an a were in the areas, it is useful to go.

    It seems however allowed. (See http://www.certguard.com/).

    I think that if you get uCertify as an aid to cross check that you have not missed student/understand all areas, then it has some use, but be aware that they can have full coverage and they could cover some areas that you don't really need to cover. Little useful overall, but do not count too much on it.

    (I never bought uCertify tests myself).

    What I have said here are my personal opinions.

  • SQL worksheet tabs automatically gel in 2.1

    Hello:

    I just do a fresh install of Oracle SQL Developer version 2.1 (63,73). Operating system is Linux.

    I open a new sql worksheet and write two queries, say «select sysdate double», then on a second line 'sysdate + 1 double'.

    I select the first query and run with F9
    I select the second query and run with F9

    I re - select the first query and the sql worksheet automatically gets frozen. Each new run open a new tab of query result.

    It's very annoying.

    I checked in tools-> Preferences-> database-> spreadsheet and "Freeze automatically result tabs" is not checked.



    This behavior has not exposed in previous versions (EA1, ai2 and RC).

  • SQL Dev 1.5.3: No "feedback" in the SQL worksheet? for example "1,000 rows deleted.

    In SQL Developer 1.5.3 seems no "feedback" in the SQL worksheet when you insert, update, and delete records. So I like the timer, it is more important for users to get comments for the UPDATE and DELETE statements; for example, it is essential to know if 0, 1 or 1,000 files have been updated by a particular SQL statement - also for DELETE queries (for example when users forget the WHERE clause, feedback is an important mechanism to realize the error).

    Is it possible to turn on your comments? ("set feedback we" seems not be honored). What is this fixed point 1.5.4? Should be presented as a feature request?

    Thank you.

  • TopLink grid 11g: conversion of SQL queries to the filters of consistency

    I would like to know how efficient the conversion of SQL queries for filters of coherence is wen search an object in the cache coherence. TopLink does something as instruction cache cache filters consistency as well? In this regard, you have number of performance?

    Thank you very much!

    Ming-Wen

    TopLink grid currently has a rudimentary filter cache that allows TopLink to only translate NamedQuery once. This allows TopLink grid to reuse the same filter on subsequent runs of this NamedQuery.

  • SQL worksheet does not scroll properly

    I am running SQL Developer v.1.5.1 on a Thinkpad T60 with Windows XP SP2 and Sun Java 6 Update 7. My problem is that when I have a large script in the SQL worksheet and want to scroll upwards or downwards, it doesn't scroll. Only the top and bottom of lines on the screen changes. If you click anywhere in the worksheet code jumps and appears garbled. The only way to scroll without interference of the display is to click on the elevator.

    I tried to update my drivers and uninstalling and re - install the JAVA virtual machine and SQL Developer without result. The problem is consistent. Everyone knows this?

    It is rare to see this kind of problems with Java 6, and you have updated graphics driver you, so the only thin left is to add the following lines to \bin\sqldeveloper.conf

    AddVMOption - Dsun.java2d.ddoffscreen = false
    AddVMOption - Dsun.java2d.noddraw = true

    I think that the other makes the first redundant (IE if you use not directdraw, then it's okay if you do on or off the screen.
