DB2 - Problem description

Problem IC61794 Status: Closed

ST_PERPPOINTS RETURNS INCORRECT VALUES

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
When using the ST_PerpPoints spatial function on an 
ST_MultiLinestring geometry that contains multiple line 
segments, 
sometimes the values returned are incorrect. 
 
The following is an example of a query that returns an incorrect 
result: 
 
 values( 
  db2gse.ST_AsText ( 
     db2gse.ST_PerpPoints ( 
           db2gse.ST_MultiLineString('MULTILINESTRING ( 
                                           (-94 37.8, -93 37.8), 
                                           (-94 37.7, -94 37.3) 
                                    )',1), 
           db2gse.ST_Point('POINT (-94.5 37.5)',1) 
 
     ) 
  ) 
) 
 
Returns: 
MULTIPOINT (-94.248676 37.330745) 
 
The correct result is: 
MULTIPOINT (-94.000000 37.500000)
