Select LONG column from remote table
Hi to all.
I have the following problem: I can't select a LONG column from remote database, when there are Join operation in the query. Example:
SELECT long_column FROM remote_table@DB
-> that's OK, but:
SELECT long_column FROM remote_table@DB INNER JOIN remote_table2@DB ON ...
-> returns: "ORA-00997: Illegal use of LONG datatype"
I cannot even perform (because there a LONG column in the joined table):
SELECT nonlong_column FROM remote_table@DB INNER JOIN remote_table2@DB ON ...
That's very strange to me because:
SELECT long_column FROM local_table INNER JOIN local_table2 ON ...
-> is OK!
Can someone help me to SELECT a long column from remote in query with JOIN clause (the LONG column is onlu in the SELECT list not in the join clause)!
Thanks a lot!
Why don't you use CLOB/BLOB instead of LONG data type?
