Hallo,
I have a table, A: IMPEXCEL_EANNR
which contains the field IMP_PRIS(= price)
It looks like this:

rather update the other table ) in other table called VARUKORGEANREL, but field in
which

Maybe this sounds simple for all of you, but I have a table with the field PRICE and

table with field PRICE, but that field has the datatype NUMBER. How can I

Hej Roland (Sverige?),
I doubt that. If all the data is number in the varchar2 column, well, you
don't need it to be varchar2.
The easiest solution seems to be:
INSERT INTO newtable SELECT TO_NUMBER(col) FROM oldtable;
Premise: all your data in that column IS number. If you're not sure,
do

What's the data like in the varchar field? Is it in number format? A quick
sample would be good.

Trigger using TO_NUMBER function would be the first thing that comes to mind.
I have designs like that, which are used for parsing so calld Bloomberg
files. Those files contain strings like N.A., -,|| ('|' is the field
delimiter) and all of those strings mean NULL. Also, stock split ratio can

Hi,
i have a column set to number(3). However this needs
to be changed to number (3,2). But i cannot do a
straight alter table as there is data in the column.
how can i get round this?

what I do is the following:
create table temp_table as select primary_key_column, number_column from
table_to_be_changed;
update table_to_be_changed
set number_column=null;
alter table_to_be_changed modify(number_column(3,2));

Welcome to the next installment of 9i new features, topic for today is:
DateTime datatypes and the functions that support them.
Here are the 4 new data types that will be covered:
TIMESTAMP
TIMESTAMP WITH [LOCAL]TIME ZONE
INTERVAL YEAR TO MONTH
INTERVAL DAY
But it will be worthwhile since i'm learning ALOT about the new datatypes for dealign
with dates/time/timezone/fractional seconds, etc.
anyways in the meantime, i had quite a few people ask about back issues :)
they are up on my website

There is a column of datatype RAW in a table.
it contains 4 numbers (4 bytes each) and a string of 54 bytes , that are
concatenated and then converted to RAW by an external C++ application.
I need to convert it back in a PL/SQL trigger.

Andrey,
You should first do a utl_raw.cast_to_varchar2 and then split the varchar2
string into individual numbers, using substr().

Any opinion
It may be better to name it specifically as INTEGER etc. but good practice
would dictate using the %TYPE option..

What is better performance-wise - to declare a variable inside a pl/sql

From a pure performance direction,
pls_integer or binary_integer is probably
the fastest.
If you declare a variable to be of
table_name.column_name%type
there are implicit constraints on the
variable and any pl/sql assignments
(in particular arithmetic operations)
have to check that the
