About us

the CURSOR Service Distribution

  • High-Value Service Provider for IBM Informix.

  • Distribution for IBM Data-Management Software (OEM/ASL/ESA licensing for ISVs).

CURSOR Service Distribution is a business unit of CURSOR Software AG, resulting from the acquisition of the Informix and development tool specialist "Nonne & Schneider" at the end of 2005.

We offer extensive technical services for IBM Informix, and as a high-value service provider we are the direct contact for all our customers' service needs for these databases.

Our services are independent from licensing through our company. Well-known customers rely on our monitoring and use our tools, while licensing and update maintenance are contracted directly with IBM.

Informix - Problem description

Problem IC57243 Status: Closed

AF SELECTING FROM A VIEW WHICH CONTAINS A SELECT WITH A SUBQUERY USING SPL
UDR

product:
IBM IDS ENTRP E / 5724L2304 / B15 - IDS 11.50
Problem description:
For clarity, a demonstration of the problem follows: 
DROP DATABASE db1; 
CREATE DATABASE db1; 
CREATE TABLE t1 (t1_c1 int, t1_c2 int, t1_c3 int); 
CREATE TABLE t2 (t2_c1 int, t2_c2 int); 
CREATE TABLE t3 (t3_c1 int); 
CREATE FUNCTION udr1 (param_1 int) RETURNING int 
   RETURN 1; 
END FUNCTION; 
CREATE VIEW v2 (v2_c1) AS 
SELECT 
   ( 
   SELECT t1_c3 
   FROM OUTER (t2, t1), t3 
   WHERE t2_c1 == t1_c3 AND t1_c1 == t3_c1 AND 
  udr1(t1_c2) BETWEEN t2_c2 AND 2 
   ) 
FROM t1; 
SELECT 1 FROM v2 WHERE v2_c1 = 3; 
This will cause an assert failure similar to the following
