idea about "make Context.getConnection() method public"

[ningpp]

i write a mysql charset and collation validate plugin which need do a sql query . but getConnection() method is private.
to do this i copy Context source code , and make it public.

sql :

select count(*) from information_schema.COLUMNS 
WHERE table_name = ? AND (character_set_name <> ? or collation_name <> ?)

SELECT count(*) 
FROM information_schema.TABLES s 
LEFT JOIN information_schema.COLLATION_CHARACTER_SET_APPLICABILITY ccsa
ON ccsa.collation_name = s.table_collation
WHERE s.table_name = ? and (ccsa.CHARACTER_SET_NAME <> ? or s.TABLE_COLLATION <> ?)
