How to generate dynamic RUNSTATS statements

Here is a handy trick to dynamically generate RUNSTATS STMTS using the SQL CONCAT and STRIP functions.

Run this SQL in SPUFI, cut and paste the generated output for subsequent processing by DSNUTILB. 

-- THIS SQL STATEMENT WILL DYNAMICALLY GENERATE 
-- RUNSTATS STATEMENTS 
-- FOR ALL TABLESPACES MATCHING THE SEARCH CRITERIA 
------------------------------------------------------------------------ 
SELECT DISTINCT 'RUNSTATS TABLESPACE ' 
CONCAT STRIP(DBNAME,TRAILING) 
CONCAT '.' 
CONCAT NAME 
CONCAT ' TABLE ALL INDEX ALL UPDATE ALL' 
FROM SYSIBM.SYSTABLESPACE 
WHERE DBNAME = 'DSQDBCTL' 
;
