Lisa,
How about this:
declare
EmpRec Emp%ROWTYPE;
type EmpTable is table of EmpRec%type index by binary_integer;
emp EmpTable;
begin
emp(1).ename := 'xx';
emp(1).ssn := 896767097;
emp(2).ename := 'yy';
end;

Good morning everyone,
well I finally have something to work on. Not being one to whip out shoddy
code, I want to write my load scripts utilizing pl/sql tables and caching as
much as I can, along with utilizing FORALL and BULK COLLECT.
The last time I did this, I was creating table rows in pl/sql INDEX-BY
tables. I had one pl/sql table for each column in the target table (that I
was going to insert modified rows to) and it worked fine, very fast in fact.
However, it was an awful mess because I ended up maintaining many many
INDEX-BY tables with one index to refer to each record.
What I'm talking about is this
table in the db is emp : enum number, ename varchar
To represent this table in memory and assemble the records I created the
following index-by tables at the module (package) level
mtab_ename
mtab_enum
and inserted values like so
mtab_enum(idx) := var1;
mtab_ename(idx) := var2;
and when it came time to insert, this is what I did
FORALL i IN mtab_enum.FIRST..mtab_enum.LAST
INSERT INTO emp (enum, ename) VALUES mtab_enum(i), mtab_ename(i);
My question is, is there a way I can have one object that represents the
structure of the entire emp table? I tried this
TYPE emptabtype IS TABLE OF emp%ROWTYPE INDEX BY BINARY_INTEGER;
mtab_emp emptabtype;
But this doesn't seem to work. I can't pull the values out (var :=
mtab_emp.ename(i)). I also don't want to use varrays just because I have
to explicitly set the size.
I also want to be able to use BULK COLLECT and FORALL. Otherwise this kind
of stuff is a waste of time. I then read in the documentation that
"Collections can have only one dimension and must be indexed by integers".
It sounds like what I want to do isn't possible.
Any suggestions or comments are appreciated. Thanks
