Actually, two questions here:
1. I have a dynamicly-built query that will be
executed using dynamic sql:
select Z, (select y from tableA t1 where
t1.id=t2.id) X
from tableA t2;
To get the value from the query, I use:
dbms_sql.column_value( theCursor, 1,columnValue);
dbms_sql.column_value( theCursor, 2,columnValue);
Now, how can I get the column name (i.e. X) using
dynamic sql?
2. I tried to use a group function in the above query
as following:
select countZ) A, (select y from tableA t1 where
t1.id=t2.id) X
from tableA t2
group by X;
The query failed and the error message was:
ORA-00904: invalid column name (i.e. Oracle says
that X is not a valid column name)
Is ther a way to work around this problem?
Thanks a lot.
