Hi
I am getting Error 302: Component "..." must be declared error whenever i qualify a schema name with table, functions, procedure etc. eg if i declare a variable as:

v_temp SCHEMA_NAME.TABLE_NAME.FIELD_NAME%TYPE;
and compile it i get
Error 302: Component "..." must be declared error

however if i remove the scehma name and do it as:
v_temp TABLE_NAME.FIELD_NAME%TYPE;
then it complies fine.

Please note that this problem is occuring in only one user/schema.
Any help

No enough data to compute.

Where do you get this error?

From where do you get the error? Which client?
"Error 302: Component " is not a database error.

Without the actual code the only thing we can say is
Quote:
PLS-00302: component "string" must be declared
Cause: In a reference to a component (for example, in the name "A.B", "B" is a component of "A"), the component has not been declared. The component might be misspelled, its declaration might be faulty, or the declaration might be placed incorrectly in the block structure.
Action: Check the spelling and declaration of the component. Also confirm that the declaration is placed correctly in the block structure.

Michel

1) do you have a schema called EMPIRE?
2) does the user you're trying to compile the function as have permissions to see empires objects?

Maybe the error is not there you think it is.
Use SQL*Plus and copy and paste your session.

If you say so.
But why don't you post it?

Before please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter), use code tags and align the columns in result.
Use the "Preview Message" button to verify.

what should i post?

I already told you that i m getting this error where ever i qualify the schema with any object (table, procedure, function...) and the error is only occuring in this particular user.
And by the way i've already read the guide.

A complete copy and paste of the procedure creation and the output from show errors. That way we could see exactly which component it's complaining about. I'm guessing it's the table name but haven't actually stated that.

I still think you've got an object called EMPIRE, becuase I can't think of any other explaination for this error.
e.g.:
Connected to:
Oracle Database 10g Release 10.2.0.2.0 - 64bit Production

SQL> sho user
USER is "LIVE"

SQL> create table test (a number);

Table created.

SQL> create table live (b number);

Table created.

SQL> create or replace procedure testproc as
  2  
  3  l live.test.a%TYPE;
  4  
  5  begin
  6  
  7  null;
  8  
  9  end;
 10  /

Warning: Procedure created with compilation errors.

SQL> sho errors procedure testproc
Errors for PROCEDURE TESTPROC:

LINE/COL ERROR
-------- -----------------------------------------------------------------
3/3      PL/SQL: Item ignored
3/8      PLS-00302: component 'TEST' must be declared
SQL> 
SQL> drop table live;

Table dropped.

SQL> alter procedure testproc compile;

Procedure altered.

SQL> sho errors procedure testproc
No errors.
SQL> 


Run the following to be sure:
SELECT * from all_objects where object_name = 'EMPIRE';

Now you know why we want you to copy and paste what you have and not just tell us.
You think you're right in your interpretation byt you were wrong.

Does not compute, who are "don" and "u"?
About 1 word out of 2 is not in the dictionary.
Please read OraFAQ Forum Guide and do not use IM speak and format your query.
