Re: Weird COMMIT <> *NONE required in query

https://www.ibm.com/docs/en/i/7.4?topic=objects-large-object-locators

A large object (LOB) locator is a small, easily managed value that is used
to refer to a much larger value.

Specifically, a LOB locator is a 4-byte value stored in a host variable
that a program uses to refer to a LOB value held in the database server.
Using a LOB locator, a program can manipulate the LOB value as if it were
stored in a regular host variable. When you use the LOB locator, there is
no need to transport the LOB value from the server to the application (and
possibly back again).

The LOB locator is associated with a LOB value, not a row or physical
storage location in the database. Therefore, after selecting a LOB value
into a locator, you cannot perform an operation on the original row(s) or
table(s) that have any effect on the value referenced by the locator. The
value associated with the locator is valid until the unit of work ends, or
the locator is explicitly freed, whichever comes first. The FREE LOCATOR
statement releases a locator from its associated value. In a similar way, a
commit or rollback operation frees all LOB locators associated with the
transaction.

LOB locators can also be passed to and returned from UDFs. Within the UDF,
those functions that work on LOB data can be used to manipulate the LOB
values using LOB locators.

https://www.ibm.com/docs/en/i/7.4?topic=functions-get-clob-from-file

The function will read the file specified by the argument, convert the data
to the default job CCSID, and return it as a CLOB locator. The function
must be run under commitment control. The locator will be freed when a
COMMIT or ROLLBACK is performed.

I am trying to run this query using iACS:

With x as (
*-- Split IFS File into Rows (at CRLF)* Select Ordinal_Position
as
RowKey, Element as RowInfo
from Table(SysTools.Split(*Get_Clob_From_File*(
'/myfolder/EmailReceived.csv'), x'0D25')) a
Where *Trim*(Element) > '|'),
y as (
*-- Split IFS File Rows into Columns (and remove leading/trailing
double quotes ")*
Select x.*, Ordinal_Position ColKey,
*Trim*(B '"' from Element) as ColInfo
from x cross join Table(SysTools.Split(RowInfo, '|')) a)

*-- Return the Result as Table*Select RowKey,
*Min*(Case When ColKey = *1* Then ColInfo End) as From,
*Min*(Case When ColKey = *2* Then ColInfo End) as To,
*Min*(Case When ColKey = *3* Then ColInfo End) as CC,
*Min*(Case When ColKey = *4* Then ColInfo End) as Reply,
*Min*(Case When ColKey = *5* Then ColInfo End) as Subject,
*Min*(Case When ColKey = *6* Then ColInfo End) as SendDate,
*Min*(Case When ColKey = *7* Then ColInfo End) as Content,
*Min*(Case When ColKey = *7* Then ColInfo End) as Body
From y
Where RowKey > *1*
*-- Remove header*Group By RowKey;

The .csv file has the pipe character as field separator, and the header
line is as follows:

From|To|CC|ReplyTo|Subject|SentDate|ContentType|Body

There is sample contents in the .csv that I won't need to show.
The thing is that I am getting this SQL error:

<error>
Message: [SQL0443] LOB and XML locators are not allowed with

COMMIT(*NONE).

Cause . . . . . : Either a trigger program, external procedure, or
external function detected and returned an error to SQL. If the error
occurred in a trigger program, the trigger was on table QDBSSUDF2 in

schema

QSYS. If the error occurred in an external procedure or function, the
external name is QDBSSUDF2 in schema QSYS. The associated text is LOB

and

XML locators are not allowed with COMMIT(*NONE).. If the error occurred

in

a trigger program, the associated text is the type of trigger program.

If

the error occurred in an external function, the associated text is the

text

of the error message returned from the external function. Recovery . .

. :

Refer to the joblog for more information regarding the detected error.
Correct the error and try the request again.
</error>

Can someone please explain why is this? I am not using updates or

deletes.

LOB and XML locators are not allowed with COMMIT(*NONE)????

What is that? FCS!

Thanks in advance.
