support CASE

SELECT
	this_.person_id AS person_i1_2_0_,
	this_.version AS version2_2_0_,
	this_.name AS name3_2_0_,
	this_.sex AS sex4_2_0_,
	this_.height_centimeters / 2.54E0 AS height_c5_2_0_,
	this_.address AS address6_2_0_,
	this_.zip AS zip7_2_0_,
	this_.country AS country8_2_0_,
	this_1_.title AS title2_0_0_,
	this_1_.salary AS salary3_0_0_,
	this_1_.pwd_expiry_weeks * 7.0E0 AS pwd_expi4_0_0_,
	this_1_.manager AS manager5_0_0_,
	this_2_.comments AS comments2_1_0_,
	this_2_.salesperson AS salesper3_1_0_,
	CASE WHEN this_1_.person_id IS NOT NULL THEN 1 WHEN this_2_.person_id IS NOT NULL THEN 2 WHEN this_.person_id IS NOT NULL THEN 0 END
		AS clazz_0_
FROM
	jperson AS this_ LEFT JOIN jemployee AS this_1_ ON this_.person_id = this_1_.person_id
		LEFT JOIN jmanager AS this_2_ ON this_.person_id = this_2_.person_id
WHERE (this_.address, this_.zip, this_.country) IN (($1, $2, $3), ($4, $5, $6));

Obviously the case looks bad, but did that cause the first LEFT JOIN to not be on the next line?
