我有以下查询：
Select DISTINCT * From
(
SELECT "WORK_CENTER"."EQNO" AS E1,
"WORK_CENTER"."CNTR_TYPE",
"WORK_CENTER"."CNTR_DESC",
"WORK_CENTER"."MFGCELL",
"WORK_CENTER"."MFG_TYPE",
"WORK_CENTER"."CUSER1",
"WORK_CENTER"."CUSER2",
"WORK_CENTER"."CUSER3",
"WORK_CENTER"."CUSER4",
"WORK_CENTER"."CUSER5",
"WORK_CENTER"."NUSER1",
"WORK_CENTER"."NUSER2",
"WORK_CENTER"."NUSER3",
"WORK_CENTER"."NUSER4",
"WORK_CENTER"."NUSER5",
"UD_DATA"."CUSER"
FROM "IQMS"."UD_DATA" "UD_DATA"
FULL OUTER JOIN "IQMS"."WORK_CENTER" "WORK_CENTER" ON "UD_DATA"."PARENT_ID"="WORK_CENTER"."ID"
LEFT OUTER JOIN "IQMS"."UD_COLS" "UD_COLS" ON "UD_DATA"."UD_COLS_ID" = "UD_COLS"."ID"
WHERE "WORK_CENTER"."MFG_TYPE"='INJECTION' AND "UD_COLS"."ID"='16'),
(SELECT
"WORK_CENTER"."EQNO" AS E2,
"UD_DATA"."CUSER" AS "U2"
FROM "IQMS"."UD_DATA" "UD_DATA"
FULL OUTER JOIN "IQMS"."WORK_CENTER" "WORK_CENTER" ON "UD_DATA"."PARENT_ID"="WORK_CENTER"."ID"
LEFT OUTER JOIN "IQMS"."UD_COLS" "UD_COLS" ON "UD_DATA"."UD_COLS_ID" = "UD_COLS"."ID"
WHERE "UD_COLS"."ID"='17') ORDER BY E1,E2
E2 是我试图用来组织数据的东西，我不希望显示此列。这是期望的结果（不显示空白列，并对格式错误的表格表示歉意）：
EQNO | CNTR_TYPE | CNTR_DESC | MFGCELL | MFG_TYPE | CUSER | U2
001 | 110T-40MM | DEMAG SYSTEM 110-430 | MOLDING | INJECTION | 1000 | test1
002 | 150T-25MM | DEMAG SYSTEM 150-320 | MOLDING | INJECTION | 2000 | test2
003 | 150T-45MM | DEMAG SYSTEM 150-610 | MOLDING | INJECTION | 3000 | test3
005 | 150T-45MM | DEMAG EXTRA 500-610 | MOLDING | INJECTION | 4000 | test4
但我得到的是：
EQNO | CNTR_TYPE | CNTR_DESC | MFGCELL | MFG_TYPE | CUSER | U2 | E2
001 | 110T-40MM | DEMAG SYSTEM 110-430 | MOLDING | INJECTION | 1000 | test1 | 001
001 | 110T-40MM | DEMAG SYSTEM 110-430 | MOLDING | INJECTION | 1000 | test2 | 002
001 | 110T-40MM | DEMAG SYSTEM 110-430 | MOLDING | INJECTION | 1000 | test3 | 003
001 | 110T-40MM | DEMAG SYSTEM 110-430 | MOLDING | INJECTION | 1000 | test4 | 005
002 | 150T-25MM | DEMAG SYSTEM 150-320 | MOLDING | INJECTION | 2000 | test1 | 001
002 | 150T-25MM | DEMAG SYSTEM 150-320 | MOLDING | INJECTION | 2000 | test2 | 002
002 | 150T-25MM | DEMAG SYSTEM 150-320 | MOLDING | INJECTION | 2000 | test3 | 003
002 | 150T-25MM | DEMAG SYSTEM 150-320 | MOLDING | INJECTION | 2000 | test4 | 005
003 | 150T-45MM | DEMAG SYSTEM 150-610 | MOLDING | INJECTION | 3000 | test1 | 001
003 | 150T-45MM | DEMAG SYSTEM 150-610 | MOLDING | INJECTION | 3000 | test2 | 002
003 | 150T-45MM | DEMAG SYSTEM 150-610 | MOLDING | INJECTION | 3000 | test3 | 003
003 | 150T-45MM | DEMAG SYSTEM 150-610 | MOLDING | INJECTION | 3000 | test4 | 005
005 | 150T-45MM | DEMAG EXTRA 500-610 | MOLDING | INJECTION | 4000 | test1 | 001
005 | 150T-45MM | DEMAG EXTRA 500-610 | MOLDING | INJECTION | 4000 | test2 | 002
005 | 150T-45MM | DEMAG EXTRA 500-610 | MOLDING | INJECTION | 4000 | test3 | 003
005 | 150T-45MM | DEMAG EXTRA 500-610 | MOLDING | INJECTION | 4000 | test4 | 005
Union 并没有真正起作用，因为它只是将“CUSER”和“CUSER AS U2”两列放在一起，因为它们实际上是同一列。
我能做些什么来解决这个问题和/或我做错了什么？（我想这很可能）
即使只是被告知要看什么也会非常有帮助。我已经为此工作了几天，但没有取得太大进展。
