I have a linked server (SQL Server 2008 to Oracle) and would like to know how to execute this statement before I query the data:
MO_GLOBAL.SET_POLICY_CONTEXT('S', 83);
I can query the data using this:
Select * from OPENQUERY (linkedservername, 'Select * from tablename')
But I'm not sure how to incorporate the set_policy_context statement. Appreciate any feedback.
Here's the correct statement:
EXECUTE('BEGIN apps.MO_GLOBAL.SET_POLICY_CONTEXT(''S'', 83); END;') at tablename;

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;

Is there any option to use not exists in openquery from SQL Server and prevent insert of values which already exist in DB2, from table.
I want to insert data from a table located in SQL Server into a table located in an IBM DB2 server, but I want to check if the value already exists or not.
This works for me actually,
if not exists (select * from openquery(puskarkc, 'select * from puskarlib.castatus'))
begin
insert openquery (puskarkc, 'select * from puskarlib.castatus')
select * from castatus
end
Is it possible to to extract SQL queries that are saved in a table?
For example
select * from saved_queries
name | statement
queryname | 'select * from mytable where myfield = 'somevalue'
I would like to be able to do something like
select * from ( extractsomehow( 'select Statement from saved_queries where name = 'queryname') ).
Unfortunately I cannot use Java so I am restricted to SQL and XML there.
I am using Oracle 11g
If you can write a stored procedure, you could use execute immediate, something like this:
select statement into v_statement from saved_queries where ... ;
execute immediate v_statement;
Before you use dynamic SQL, think carefully about whether or not you actually need it.
I have a linked Firebird database on my SQL Server 2008 via ODBC.
I can execute a query like this and I get the wanted results:
SELECT * FROM OPENQUERY(LINKED_SERVER_NAME, 'SELECT * FROM TABLE_NAME')
Now i wonder how can I execute stored procedure with one parameter input.
I have tried:
SELECT * FROM OPENQUERY(LINKED_SERVER_NAME, 'STORED_PROCEDURE_NAME 00001')
and
EXEC LINKED_SERVER_NAME.STORED_PROCEDURE_NAME '00001'
with no success...
Any tip would be appreciated !
I dont know in MSSQL but you can try
SELECT * FROM OPENQUERY(LINKED_SERVER_NAME, 'SELECT * FROM STORED_PROCEDURE_NAME(00001)')
is there any Query syntax (predefined )in SQL Server can show a function/procedure body-script?
sth like:
Select * from ShowScript('MyFunctionOrProcedureName')
I think you want
exec sp_helptext 'MyFunctionOrProcedureName'
