Hello.

I'm trying to use CONTAINS function in PL/SQL. But it break out with some errors.
Please tell me that reason?
(Oracle 7.3.2, PL/SQL 2.3.2.2 on HPUX 10.20)

This is simple example:

declare

key varchar2(16);
begin

    select text_key into key
    from text_view
    where CONTAINS(text, 'wine')>0;
end;
/

ERROR at line 6:

ORA-06550: line 6, column 7:
PLS-00201: identifier 'CONTAINS' must be declared
ORA-06550: line 4, column 1:

PL/SQL: SQL Statement ignored
