subject: Error handing field CLOB

Hi,

I have a file with 38000 records, the record has only one field char(900).
I need to join these fields in a single field type CLOB (1G). The file size
exceeds 30 megabytes . I use the following instruction:

SELECT CAST ( LISTAGG ( CAST ( TRIM ( FIELD ) AS CLOB ( 1 K ) ) ) AS CLOB
( 1 G ) )
INTO VARIABLE
FROM LIBRARY.FILE ;

Where VARIABLE is CLOB ( 1 G)

When I execute this sentence, I obtain an error, because the result is
greater than one mega then I change the instruction by:

SELECT GET_CLOB_FROM_FILE ( 'LIBRARY/FILE(MEMBER)' , 0 )
INTO VARIABLE
FROM SYSIBM . SYSDUMMY1
WITH CHG ;

This instruction run ok, but the content of the variable is incomplete
because it cuts information from the records that it unites.

Example:

-First records of the file:
<ARInvoiceDataSet>
<InvcDtl>
<Company>81</Company>
<InvoiceNum>10771</InvoiceNum>
<InvoiceLine>1</InvoiceLine>
<PartNum>E12720-60-999</PartNum>
.....
.....

- Expected string:

<ARInvoiceDataSet><InvcDtl><Company>81</Company><InvoiceNum>10771</InvoiceNum><InvoiceLine>1</InvoiceLine><PartNum>E12720-60-999</PartNum>.........


- Obtained string:

Dtl><Company>81</Company><InvoiceNum>10771</InvoiceNum><InvoiceLine>1</InvoiceLine><PartNum>E12720-60-</PartN>....


This process is in iSeries V7.3 in a store procedure sql pure.

Does anybody have an idea?

Thank you.
