Re: CREATE TABLE AS ... WITH DATA

I see that documented everywhere but haven't found an explanation as to
why. It's not like I'm trying create a table with a host variable in the
table. I'm just trying to select records. But doesn't matter anyway. It
can be dropped. I've changed it to create the table first and then do a
insert into.

Michael, I think the answer is simply that host variables are not
allowed on a CREATE statement.

Is this suppose to answer my question? Because I'm not following you. I
understand that host variables are used in prepared statements but why

are

they not permitted in this prepared statement?

Exec SQL
Create table qtemp/tmptable as (
select * from myfile
where company = :hostcpy) with data;

I'm wanting this run multiple times in the program, so reuse and
performance is needed.

What I don't get is that this is okay.

Exec SQL
Create table qtemp/tmptable as (
select * from myfile
where company = '001') with data;

Host variables are used in 'Prepared' statements. The reason for that

is

as

the name suggests, they are prepared. ie they are created before they

are

run, and when run, the host variables are passed to the already

prepared

statement as input values.
This is basically for performance reasons, as the prepared statement

can

then be reused multiple times efficiently

Okay, I've found where is says that it's not allowed.

The select-statement must not refer to variables or include

parameter

markers.


But why, I dont see the explaination why? I'm not seeing why the

compiler

would care if I use a hard coded value or a host variable to select
records.
