SELECT tab1.column1 FROM DB2.Schema.table1 tab1;
I try to execute this above query from Database 1. The table1 exist in DB2 database. It showing following error.
ORA-00933: SQL command not properly ended
00933. 00000 - "SQL command not properly ended"
No need to mention database name in your select statment. See below:
SELECT tab1.column1 FROM Schema.table1 tab1;
DB Link Usage:
CREATE DATABASE LINK sales.hq.acme.com
CONNECT TO scott IDENTIFIED BY tiger
USING 'sales';
Once this database link is created, you can query tables in the schema SCOTT on the remote database in this manner:
SELECT *
FROM emp#sales.hq.acme.com;
You can also use DML statements to modify data on the remote database:
INSERT INTO accounts#sales.hq.acme.com(acc_no, acc_name, balance)
VALUES (5001, 'BOWER', 2000);
UPDATE accounts#sales.hq.acme.com
SET balance = balance + 500;
DELETE FROM accounts#sales.hq.acme.com
WHERE acc_name = 'BOWER';
You can also access tables owned by other users on the same database. This statement assumes SCOTT has access to ADAM's DEPT table:
SELECT *
FROM adams.dept#sales.hq.acme.com;
The previous statement connects to the user SCOTT on the remote database and then queries ADAM's DEPT table.
Note: Dblinks are used using '#' symbol.
You don't need to prefix the db. Just make sure you are in the right schema using:
ALTER SESSION SET current_schema = schemaname;

I want to select data from SQL Server to Oracle (Toad Apps).
If from Oracle to SQL Server its done like this
Insert Into M_CLASSIFICATION_ORACLE
SELECT * From OPENQUERY ([B1APPS], 'select * from V_Classification_Asset' ) AS derivedtbl_1
How about in Oracle (Toad apps)?
You can able to do it by using CREATE DATABASE LINK:
Create a Database Link to connect to SQL Server:
CREATE DATABASE LINK link-name ...
Query SQL Server using the Database Link:
SELECT * FROM sqlserver-table-name#link-name;

Since a couple of days I can't execute CREATE and TRUNCATE SQL statement using Oracle 12 and Toad 12, ONLY if I terminate my statements with a semicolumn. I've always used the same connections, user and tables, but now I receive these errors while querying:
CREATE TABLE W_TEST_01
AS SELECT *
FROM CFG_FLOW
WHERE 1 = 2;
ORA-00933: SQL command not properly ended
CREATE TABLE W_TEST_01 (PIPPO NUMBER);
ORA-00922: missing or invalid option
TRUNCATE TABLE W_TEST_01;
ORA-03291: Invalid truncate option - missing STORAGE keyword
Can someone please help me?
Try with parentheses, like this:
CREATE TABLE W_TEST_01
AS (SELECT * FROM CFG_FLOW WHERE 1 = 2);
And if it still does not work, try to see the CTAS Tips
I advise you to take a look at the following link
Hope this can help!
How can rows be inserted into a table from a table in a remote database?
We currently have a stored procedure which does this using a database link. However, we are having to delete the link because our company policy doesn't allow their usage.
begin
...
execute immediate 'insert into '|| table_name
|| ' (select * from schema_name.'|| table_name ||'#link)';
...
end;
I'm unable to use the COPY command as it appears to be not recognized.
COPY FROM username/pwd#SID
insert into table_name using (select *
from table_name);
Error report:
SQL Error: ORA-00926: missing VALUES keyword
00926. 00000 - "missing VALUES keyword"
*Cause:
*Action:
According to this SQL Plus page, COPY command is now obsolete.
Your Query syntax is slightly wrong, and you just need to specify INSERT/REPLACE/CREATE .. and INTO is NOT needed.
COPY is not obsolete, but it ends up with some encoding issues.
You would use the line continuation character to get around that.
COPY
FROM username/pwd#SID
TO username/pass#SID2
insert
table_name
using
select * from schema_name.table_name;
You can also, download the table data into a text file, and use SQL*Loader to load the data into the another Database.
I prefer the SQL*Loader option! Since maintenance is easy!
For download,
- you can either use SPOOL with delimiter option as mentioned Here
- Write a ProC/PLSQL to output the data into a File (Method 4 in ProC, OR select column names from dba_columns))
I created a sql server database with name of abc-123, in that I created a table Emp, when I run likeselect * from abc-123.emp; I am getting the results.
But when I am trying to grant some privilege to the user I unable to do that, getting syntax error near hyphen .
will any one help me?
Make sure you are escaping the names with [] (T-SQL) or "" (ANSI SQL). You are using non-standard naming.
-- Sample select
SELECT * FROM [abc-123].[dbo].[emp];
SELECT * FROM "abc-123"."dbo"."emp";
1 - Can you send me an example of the grant TSQL? If you are doing the action from SSMS, right click and script the code.
2 - Here is the link to the GRANT TSQL command. I do not see any syntax like you are trying.
http://technet.microsoft.com/en-us/library/ms188371.aspx
TO 'drupal'#'localhost' IDENTIFIED BY 'Drup#l';
First, it should be [drupal#localhost]. Second, I never seen the IDENTIFIED BY clause. Where are you getting that information from?
3 - Here is a quick TSQL script that creates a badly named database and user. If possible, change the name of the database and user.
Also, if you are granting permissions at the table level other than db_owner (very granular and a-lot of maintenance), then create an user defined database role. Add securables to the role and add your user to the role.
http://technet.microsoft.com/en-us/library/ms187936.aspx
Sample code.
-- Create new database
create database [abc-123]
go
-- Use new database
use [abc-123];
go
-- Create table from sample data
select
[BusinessEntityID]
,[PersonType]
,[NameStyle]
,[Title]
,[FirstName]
,[MiddleName]
,[LastName]
,[Suffix]
,[EmailPromotion]
, cast([AdditionalContactInfo] as varchar(max))
as [AdditionalContactInfoTxt]
, cast([Demographics] as varchar(max))
as [DemographicsTxt]
,[rowguid]
,[ModifiedDate]
into
[abc-123].[dbo].[emp]
from
AdventureWorks2012.Person.Person;
-- Create a login
CREATE LOGIN [drupal#localhost] WITH PASSWORD=N'Ja08n13$', DEFAULT_DATABASE=[abc-123]
GO
-- Create a user
CREATE USER [drupal#localhost] FOR LOGIN [drupal#localhost] WITH DEFAULT_SCHEMA=[dbo]
GO
-- Add to database owner role
EXEC sp_addrolemember 'db_owner', [drupal#localhost]
GO
Output with user in db_owner group.
Use Back Quote for the DB name
select * from `abc-123`.emp;
or, select the existing database with a USE statement and run the query.
USE `abc-123`;
select * from emp;
Use [] round the database name:
SELECT * FROM [abc-123].[dbo].emp;
OR
SELECT * FROM [abc-123].dbo.emp;
if you are using databasename with table name then suppose to specify the schema name also.select * from [abc-123].dbo.emp
Is there an Oracle SQL tool that builds insert statements from a result set? We are currently only allowed to use a tool called SQL Station. I'd like to either suggest a tool, like Rapid SQL or CrazySQuirrell, or build my own re-usable chunk of sql.
Where is this result set coming from? If you mean that you want to execute a SELECT, then insert the resulting data into another table, you can do that in a single SQL statement:
INSERT INTO table2 (columnA, columnB)
SELECT columnA, columnB
FROM table1;
PL/SQL Developer will do this as well. I've used both PL/SQL Developer as well as Oracle's SQL Developer, and in my opinion PL/SQL Developer has a smoother and more consistent interface. Not sure about SQL Developer, but PL/SQL Dev. also lets you export result sets as CSV,XML, and HTML.
It also behaves OK under WINE if you're running Linux.
If you want command line tools, the free cx_OracleTools will do this, and some other nice things as well.

Yes look at Oracle sql developer.Its free can be downloaded from otn.oracle.com
I found this solution, which is what I'm using now. Thanks for all of the help.
It turns out we can use SQL+ too. For some reason I can't run it in SQL Station.
COPY FROM userid/password#from_DB TO userid/password>#to_DB INSERT toDB_tablename USING SELECT * FROM fromDB_tablename where ....;
commit;
In a pinch, using string contatenation works great for smaller statements you want to build:
Select
'Insert Into MyOtherTableTable Values(''' || MyMainTableColumn1 || ''' and ''' || MyMainTableColumn2 || ''')'
From MyMainTable
Right click on the result set of the query, you will get a pop up. select export data and insert. it will ask you for the location to save the file in which insert statements are generated. give file name and the path to save it.
I know it is too late but It could be helpfull for somebody.
If you go to the table, you can "export" the data. The second step is "Specify Data" where you can add some filters.
This only works for a table data.
Cheers
With Oracle SQL-Developer type and execute as script (F5):
select /*insert*/
* from dual;
output:
Insert into "dual" (DUMMY) values ('X');
you can try also /*csv*/" or /*html*/
