Oracle Bug

Rails
1

I’m using 2 database. The first wrote in MySQL and the second in Oracle.
If i use the command “SET_TABLE_NAME” to forge the model to use another
table, there isn’t no error with MySQL, while with Oracle if i ask the
view “_Form.rhtml” The compiler tell me “No sequence in SELECT
TableName_seq.nextval id from dual”(???).
Could someone tell me where is the bug?.
Could it be a problem into the oci8 library?

You need to create an oracle sequence that is named TableName_seq, that
should do it.

This is how to create a sequence:

CREATE SEQUENCE TABLENAME_SEQ INCREMENT BY 1 START WITH 100

Thanks Chris,
But now the compiler tell me it:

invalid column name: INSERT INTO ago.prova_stats (cognome, nome, id,
telefono) VALUES(‘Medda’, ‘Ivan’, :id, 70565611)

where ago.prova_stats is the table used by me and that have only the
columns ‘cognome’,‘nome’ and ‘telefono’.
My table hasn’t the column ‘id’(???).Why Rails search it?

Ok,
Now the compiler search the ‘id’ column into the table. But tell me it:

invalid column name: select * from (select raw_sql_.*, rownum raw_rnum_
from (SELECT * FROM ago.prova_stats WHERE (ago.prova_stats.id = ‘1.0’) )
raw_sql_ where rownum <= 1) where raw_rnum_ > 0

The problem is a bad ‘id’ type? I say Oracle to ALTER the Prova_stats
table,to contain the column ‘id’ and i give it the ‘NUMBER’ TYPE.
Is it correct? I think no.
