Re: Convert a substring to a decimal

I suspect the issue is that the data is actually looks like

000100220309--First line of source..

The problem is that
cast(substr(1,6) as dec(6,2)
isn't going to work since there's no decimal point in the string.

Old school solution would be
cast((cast(substr(1,6) as num(6,0) / 100) as num(6,2))

But the new Interpret should work quicker
interpret(substr(1,6) as num(6,2))

True, which I also mentioned in my post yesterday as to the automatic
conversion.

But maybe he is at an earlier release - I thought this automatic cast
was done a long time ago, but .....

The error is a cast error, so who knows? Running knows!

That's not the problem...

The Db is perfectly happy loading a zoned column from a packed value or
vice versa...

Heck you can use a plain old integer also.

Sure there's an extra conversion behind the scenes, but it has always
worked as long as the value is compatible.

The file he is writing to is a source physical, those fields are zoned -
see my reply from yesterday.

Cheers and see you next week in Wisconsin!

Question: The first 6 characters (you try to convert) are really

digits.

Can you pleas show (a few rows) what is in your file.
We need to know if it is really decimal/Packed or numeric.

Subject: Convert a substring to a decimal

I am battling to get this to work.

I have a PC file with source from another system. The file is a basic

text

file with no delimiters.

I need to import it into a source file and preserve the SRCSEQ, SRCDAT

and

SRCDTA.

I have tried to use a SQL IMPORT as follows.

I have tried

INSERT into Lib/File
(select
cast(substr(1,6) as dec(6,2),
cast(substr(7,6) as dec(6,0),
substr(13,100)
from QTEMP.File);

I keep getting CAST errors SQL0420.

How could I achieve this?

TIA, DArryl Freinkel.
