This is also the type of results that I have observed in the past in testing.
The tableMetaData.getColumnName(i) will also return back the correct mixed
case result. Ex. from table below.
1 Host
2 Db
3 Username
4 select_priv
Not only does this apply to columns but also to table names that are quoted
Normally I use the following table to test such occurrences in my code.
DROP TABLE IF EXISTS "keY_tAble2";
CREATE TABLE "keY_tAble2" (
"Host" char(60) NOT NULL default '',
"Db" char(64) NOT NULL default '',
"Username" char(16) NOT NULL default '',
Select_priv boolean NOT NULL default TRUE,
PRIMARY KEY ("Host","Db","Username")
);
