Tables not recognised post conversion

Question

I recently performed a migration from MS Access to Oracle SQL via the Oracle SQL Developer Application. There were a number of conversion errors, many due to spaces in table names and alike.
Despite the reported errors, I can see Views for all the tables in from the original MS Access file in the converted SQL file. However, when I try to run a continual script containing excerpts (copied + pasted) from each individual Views in the converted model, I get fundamental errors such as:
ORA-00942: table or view does not existThe Tables are visible in the Views sections, but I am wondering if the above error could arise solely because of incomplete conversion due to spaces appearing in Table names. The converter has attempted to replace spaces with underscores in the Table names, but looking within the SQL code under individual Views, I can see that underscores have not been inserted.
On another matter, how would one deal with the use of reserved names when Table column names have to use certain names such as Date and Value because they are linked to data feeds that use these terms?
Any suggestions on these problems would be gratefully received.
Many thanks

Answer 1

I've now re-run the migration, converted the captured XML file and then finally generated the converted file to create continuous script with translated code extracted from MS Access.
I get the same translation errors as before in the migration log, following the conversion. Following generation, some of the code in Views is greyed-out, with comments stating:
/*TODO: Cannot convert to viewLooking through the code, it seems that INSERT INTO statements from MS Access are not converting properly, for example:
INSERT INTO [Table A] ( Column_1 )
SELECT [Table B].Column_1
FROM [Table B] LEFT JOIN [Table A] ON [Table B].Column_1 = [Table A].Column_1
WHERE ((([Table A].Column_1) Is Null) AND (([Table B].Column_1) Is Not Null))
GROUP BY [Table B].Column_1;
generates to:
CREATE OR REPLACE VIEW Append_Column_1 AS
/*TODO: Cannot convert to view
INSERT INTO Table A
( Column_1 )
( SELECT Table B.Column_1
FROM Table B
LEFT JOIN Table A
ON Table B.Column_1 = Table A.Column_1
WHERE ( ( (Table A.Column_1) IS NULL )
AND ( (Table B.Column_1) IS NOT NULL ) )
GROUP BY Table B.Column_1 );
-- intentional generation error
SELECT NULL FROM DUAL;
But on a more simple note, I cannot seem to even perform a simple select * from Table_Name as the tables are not found, even though I can see them. This looks like it is most likely a problem with the schema: SELECT * FROM schema_name.Table_name should work, but the schema I think I have applied is clearly not what is present in the original Access file.
Before I am able to capture the XML file IN SQL dev, I need to create a repository in the user area of the database to which I am migrating. This process seems to apply some structure to the user area, and I think this is the source of the inability to perform SELECT queries.
