Informix - Problem description

Problem IT13243 Status: Closed

INSERTING A BLOB VIA A STORED PROCEDURE CAN CORRUPT BLOB CONTENT

product:
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
When using a stored procedure which is taking a blob argument
and storing this blob into a table with the blob being stored in
a separate blobspace can corrupt the blob content.

The stored procedure scheme is

CREATE PROCEDURE p1(col1_byte references byte)
...
INSERT INTO tab1(col1) VALUES(col1_byte);

with a table containing a blob column col1 like this

   col1 BYTE in blob1

This happens when the blob inserted is larger than a certain
threshold. One observed threshold was 32 KB.
