Re: Making the most, or over-thinking it - SQL for uploads

On IBM i you could use OmniFind (5733OMF) to perform text searches like you
are suggesting on unstructured data. You do have to set up the indexes in
OmniFind but they are very simple to do.

IBM i does have a solution, just almost no one uses it.

LOL

Duane - it's not due to any lack on your part - as Buck is sayin, text files
are unstructured things.

Now if you have SQL Server, or MySQL, it is probably possible to have a link
or some such that can pull stuff out of the text fiel - assuming it is
either delimited or fixed-length data.

This just doesn't feel "convenient"! Have the text file saved or otherwise
delivered to an IFS directory and have a regular job that imports it to a
holding file, then run SQL on the i that does does the WHERE stuff for you.

Easy? Yep! At least IMHO

Vern - Not necessarily a one-time task as importing data from PC to DB2 is

done constantly, and there are many ways to do so. However, using SQL is my
FIRST thought over most of the tools that we have access to, simply because
of its convenience. At least perceived convenience. As to the method that
I used to get the data this time, I used Access Client Solutions Data
Transfer. But doing so forced me to load the entire record to a DB2 data
file from which I used interactive SQL from an IBM i ACS emulation session
to INSERT my selected fields. Note: my first transfer using ACS was not
exactly easy until I figured out how different it was from the old Client
Access. But I endured and achieved the success I needed to "get 'er done".

Buck - I figured as much since I couldn't find much in the way of

assistance through Google or WDSCI-L. But I wasn't sure I had used the
correct terminology in my search. I am fairly certain that I have access
to MySQL or SQL server, because I've toyed with it on non-IBM i projects.
Very briefly. And the files I used were already structured for use with the
access. But I'm not familiar with setting up the PC to interact. Thus the
request for a primer, which was basically a shot in the dark. I think I
understand what you are saying about it being a part of a MySQL schema
already set up, which it is not.

I really just figured that I could access text files similar to accessing

them as done on IBM i. I also figured that it was my own lack of experience
and knowledge of setting up the PC that caused the inability to just find
the file and open it up.

figured out the set up to access text files on a PC (using SQL).

Generally speaking, you can't.
Think of SQL as a client-server relationship.
There's a client, which accepts SQL statements like SELECT COLUMN FROM

TABLE, and there's a server which the client connects to, and acts upon that
statement.

On a typical Windows PC, there's no server to handle the SQL statement.
So if you're talking about a regular .txt file which you can edit with

Notepad, you aren't going to use SQL to do anything with it.

On the other hand, if you have DB2 or MySQL or SQL Server loaded and

running on that PC, and the file is part of a schema inside the database,
you can connect to it if you have the appropriate JDBC driver.

What's the setup on the PC?
