Posted by perallis at May 11. 2009Example, for table staff and for query "select * from staff where id=10"
Before you run the db2expln, you have to enable the explain tables, see the commands below:
cd <instance directory>/sqllib/misc
db2 -tvf EXPLAIN.DDL
db2expln -d sample -g -q "select * from staff where id" -t
The option -t means: Terminal Output, if you use the option -o <fileoutput>, your results will be saved in a file
and the option -g means: graphic output.
