How to execute the sql statement in the file beats?
I want to execute after the statement
C:\ > sqlplus/nolog
SQL > conn scott/tiger
SQL > select * from tab;
I know I can achieve it following test.bat and testdb.sql file
test.bat is:
sqlplus/nolog @testdb.sql
TestDB.SQL is:
Conn scott/tiger
Select * from tab;
Now I don't want to use the sql file, I want only use bat file, as follows:
test.bat is:
sqlplus/nolog
Conn scott/tiger
Select * from tab;
When I run test.bat, I find only one sqlplus /nolog execute statement, do not execute other statements.
(1) I want to know if there is a method to run the SQL file by fighting without a sql file? How to make it happen?
(2) if I call the sql file, how to hide the password of user? Because I don't want other people to know scott password, if I use conn scott/tiger in testdb.sql, other person can see testdb.sql and the password. Is there a good way to avoid?
Thank you!It works a bit different in Windows. Create a file is like this:
( echo conn scott/tiger@orcl echo spool c:\temp\list.txt echo select sysdate from dual; echo spool off echo exit ) | sqlplus -s -l /nolog

Thank you.
GooGyumThere are two problems with your variable declaration:
1. the name of the variable and type are thew misplacement autour.
2. you may not use a host variable type.
If you change this to:
EXEC SQL BEGIN DECLARE SECTION;
int num1;
EXEC SQL END DECLARE SECTION;Then it will work very well.

How to get the SQL if I get exception
I get this exception and do not know what was the actual sql with the variables of liaison who was executed.
sqlmesg = error in the select query to retrieve the segment associated with a pair of cables: ORA-01006: there is no bind variable
y at - it a way to get the real sql executed so I know what mistake I did.I thought your question was about how to view the SQL statement and bind variables in the exception. The answer to that is to put variables in the exception message.
The root cause of the problem seems to be that your dynamic SQL statement may require 3 or4 variable bind but your USING clause specifies always 4 values if the underlying SQL statement has 3 positions, it will lead to an error.

How to create the logical tables &; how to give joints according to obiee 11g?
Hello
I have again to obiee 11g. I want to create the logical tables in MDB layer.
After that I want to give joins according to MDB.
I don't know, how to create the logical tables and how to give joints according to obiee 11g?
Please help me.
Thanks in advance,
A.Kavya
Hello
The new logical table is right click on the MDB itself, for the join you generally in the business model diagram (again right click on objects).
Maybe it's better if you start from a kind of tutorial to at least have an overview of what is happening where (layer business and physical layer etc.).
Take a look at what Oracle has available: Oracle BI EE 11 g
And no doubt, it can be a good start: https://apexapps.oracle.com/pls/apex/f?p=44785:24:0:NO:P24_CONTENT_ID, P24_PREV_PAGE:9787, 2
