DB2 - Problembeschreibung

Problem IC64986 Status: Geschlossen

GENERATING AN EXPLAIN OF A QUERY MIGHT RETURN EXP0021W IN SPATIAL ENABLED
ENVIRONMENT.

Produkt:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problembeschreibung:
Generating an EXPLAIN of a query might return the following 
warning messages in spatial enabled environment. 
 
 
EXP0021W  Table column has no statistics.  The column <column 
name of spatial coumn> of table 
"<schema>  "."<table name>" has not had runstats run on it. 
This can lead to poor cardinality and predicate filtering 
estimates. 
 
This is due to  DB2 doesn't  collect the statistics for the 
spatial extender column. DB2 optimizer should block above 
warning message for spatial extender column
