In Oracle SQL, I can create a dummy table thanks to the code shown below:
select crca.*
from my_real_table real_table,
table(ntde.ENCRYPT_ALL(:inputParam)) enc
where
...
I would like to be able to do same thing without using ntde.ENCRYPT_ALL
, I would like to do something like that:
select crca.*
from my_real_table real_table,
table(:inputParam) enc
where
...
It does not work and I get this error:
- 00000 - "cannot access rows from a non-nested table item"
*Cause: attempt to access rows of an item whose type is not known at
parse time or that is not of a nested table type
*Action: use CAST to cast the item to a nested table type
Do you know how to do that please?
As the exception says, use CAST
:
SELECT c.*
FROM my_real_table r
CROSS JOIN TABLE( CAST(:inputParam AS your_collection_type) ) c
This assumes that:
the bind variable contains an collection (and not a string); and
the bind variable is being passed from an application (this is a Java example ); and
you have created an SQL collection type to cast the bind variable to. For example:
CREATE TYPE your_collection_type AS TABLE OF NUMBER;
Or, instead of creating your own collection type, you could use a built in collection (or VARRAY
) such as SYS.ODCIVARCHAR2LIST
.
