How To Connect To Oracle To Retrieve Data Using SQL Language
Jan 9, 2012
how to connect to Oracle to retrieve data using SQL language. I've started with a new company which is pretty much a sink or swim type of environment meaning you're an idiot if you don't figure it out on your own. I was told that we use Toad for Oracle 10g. I was given a server name; location and an .ora file named tnsnames that was given to me but I have no clue what to do with. I've come from companies where this was already setup. You just go into access to retrieve the data.
II have totally hit a brick wall with all the other roadblocks I encounter and all researched out. Where I can get step by step instructions on how to connect to start sql in Toad/Oracle?
My company already work with Oracle 10g, I developed an application using this database and asp.NET. It allows the management of BD and exploitation of these data by clients via ASP pages.
Now I must use Microsoft Exchange (especially the calendar) to retrieve data from the Oracle database and embed links to setup my ASP pages to the calendar.
Being new to Exchange, my questions are:
- It can be done? - Should I use a particular driver? - Some idea ?
I'm developing a new batch program retrieve data from oracle to excel.Normally i insert those data into single sheet. Is it possible if I want do this into multiple sheet.
Eg: I need to insert data base on branch category. different sheet for different branch but still in a single workbook?
I installed timesten server and client on different machines in LAN, but with the same user and group - ttadmin:ttgroup When I tried to connect to server with ttisqlcs -connStr "DSN=sampleCS"The output gave me error messages as below connect "DSN=sampleCS";S1000: Failed to retrieve IP address of the system. System error: -2The command failed.Done. The related part in sys.ttconnect.ini is set as below
sys.odbc.ini [ODBC Data Sources]sampleCS=TimesTen 11.2.2 Client Driver [sampleCS]TTC_SERVER=192.168.0.206TTC_SERVER_DSN=nredb_ds
What does it mean by "retrieve IP" ?Does it try to resolve IP by the hostname even when I already gave it the ip address?By the way I can ping 192.168.0.206 and telnet at port 53397 with no problem.
I've recently been asked to replace certain English text fields with their French translation. I thought I could do this with the replace function: line_desc_reformed := replace(l.Line_Description,'Labor Item for Regular Hours','Main d uvres pour les heures rgulire');
The special characters do not get translated. So I tried the CONVERT function: line_desc_reformed := CONVERT(line_desc_reformed, 'WE8MSWIN1252', 'WE8DEC').
All gets translated except for the tick mark after the d. It gets replaced by an upside down? I have tried several different language sets and can not get that to convert.
also when using the dbms_xmldom to convert this to xml, the also gets replaced by an upside down ?. I don't belive you can change the charset when using this package.
When I transfer the data from Oracle to MS SQL I have one column in a table which is of Arabic Language.The data is fine in Oracle but when I transfer it to MS SQL Server I see that the text in MS SQL server appears as junk.
I have an Oracle DB's charset configured for Korean language and things in there are English and Korean and they are working fine. If i try to import a txt file with Chinese characters into the DB. It doesn't show correctly on query.
Is there any way I can solve this ? Since I find that there are many charset / NLS language options througout DB. I read from others that they have the following response. Any alternative beside changing the whole DB charset ?
Recreate the database with the correct character set Convert the database to AL32UTF8. Documentation link Change the databases National Character Set to AL32UTF8 & change your application to use NVARCHAR2()/NCHAR() datatypes instead of VARCHAR2() (documented at the same link as above)
My colleague sent me a sql script to copy and execute in Toad for Data Analysts (see attached). Once I execute I get error messages on the date and a few other lines. My question is should I completely rewrite the script?
I would rather have this in a grid format anyway with the same data instead of how this script is pulling. I'm very green when it comes to this (if you didn't notice) and need some insight esp. on the date format considering the date column has 10 digits i.e. 1209105576.
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit) Delphi 2010 Professional Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator. - Data source name: bt_user - TNS Server Name: localhost/xe - user bt_user - Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC) - Set database name to "bt_user". - Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form. - Select "connection string" and open the dialog. - Click "build string". - Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection. - In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1) - Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
I downloaded Oracle Database 11g Express Edition R2 to test Apex (I've never used). I want to know how to change the language of the version of Apex (integrated with Oracle Database 11g XE)? I would apex in French.
I tried more to write Bangla in Oracle 10gR1, or 10gR2 or Express but failed. When I write bangla in the "emp_name" field for employee name this can be save, But when I execute to see the data again then the data comes with a big change like some symbol for some character.
I am writing a SQL inside an application to retrieve data from a table for certain IDs or for All employees based on the user's input. I create a variable :SELECTION for the where clause. When I run the SQL, I receive the error of missing right parenthesis. There is no error if I hard code the IDs.
If the input is 'All' -> the variable :SELECTION is blank so if the SQL :
select name, address, ID from employee :SELECTION
will be
select name, address, ID from employee
If the input of users ID as '1234','9999' - > the :SELECTION = ' where ID in (:VARIABLEID)' :VARIABLEID = '1234','9999'
so the SQL: select name, address, ID from employee :SELECTION
should be
select name, address, ID from employee where ID in ('1234','9999')
However, I got the missing right parenthesis error. I suspect it is something with the single quote, so I tried different ways, but it is still not working.
I am interested about the fast way to access all data in physical block. what is the quick way to bring data blocks using the rowid, I found this script but soon as I can have faster access:
select * from table_name t WHERE ROWID between 'AAAUaOAAEAAHkJiAAA' and 'AAAUaOAAEAAHkJiAA8'; where 'AAAUaOAAEAAHkJiAAA' is the last element in the block and 'AAAUaOAAEAAHkJiAA8' is the first one
my question is can retrieve all the data in one block more quick than this query.
I want to insert 1st two rows into Hierarchy table, then I would like to update Supervisor_2 to Supervisor_4. Here I don't want to use 'CONNECT BY PRIOR', as it take more time to execute (there are millions of records).SQL code for same.
1. For each of the Filename, if originating_site is not the same as receiving_site, it means that the file has been sent to receiving_site but has not been acknowledged received yet.
2. For each of the Filename, if originating_site is the same as receiving_site, it means the file has been sent and received by the receiving_site.
My task is to list out all the Filename per receiving_site that has been sent, but not received yet by the receiving_site. For example from the sample data above, I am expecting to see that siteA, fileB has not been received yet.
How can I do that? I had tried MINUS and NOT EXISTS command, but I am just not able to get the result that I want.
CREATE TABLE MAT (matrl varchar2(100), date_man date, weight number(10) );
INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat1','12-DEC-10',100); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat2','13-DEC-10',200); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat3','21-DEC-10',300); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat4','26-DEC-10',400); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat5','22-DEC-10',500); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat6','02-DEC-10',600); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat7','23-DEC-10',700); INSERT INTO MAT(Matrl,DATE_MAN,WEIGHT) VALUES ('mat8','07-DEC-10',800);
I am using LOV on some field to retrieve data, but sometimes it does not retrieve anything cause of unavailability of date its fine but i want to put N/A in that field when such condition is occurring .
select * from testing Quote: ID NAME REDATA -------------------- -------------------- -------------------- 1 ABC,DEF,GHI,LKJ 000001 2 MNC,GHI,CTF 000002
2 rows selected
select * from testing where name like ('GHI,TCF');
now my output should be as above because GHI is common in both the names.if any of the where condition string matches the Name field then I need that record to be retrieved.
