The problem of case inconsistency between the view fields created in Dameng database and the sql

1. There is a view table creation statement as follows:

CREATE OR REPLACE VIEW "ASSET"."ip_area_view"
AS
SELECT
bbb."ID" as id,
bbb."IP" as ip ,
bbb."SECURITY_DOMAIN_NAME" as security_domain_name
,
bbb."COUNTRY" as country,
bbb."AREA" as area,
SUBSTRING(SUBSTRING(bbb."LONGITUDE_LATITUDE" FROM 1 FOR POSITION(' ' IN bbb."LONGITUDE_LATITUDE") - 1) FROM POSITION('经' IN SUBSTRING(bbb."LONGITUDE_LATITUDE" FROM 1 FOR POSITION(' ' IN bbb."LONGITUDE_LATITUDE") - 1)) + 1
) AS longitude,
SUBSTRING(
SUBSTRING(bbb."LONGITUDE_LATITUDE" FROM POSITION(' ' IN bbb."LONGITUDE_LATITUDE") + 1)
FROM POSITION('纬' IN SUBSTRING(bbb."LONGITUDE_LATITUDE" FROM POSITION(' ' IN bbb."LONGITUDE_LATITUDE") + 1)) + 1
) AS latitude,
bbb."IS_INTRANET" as is_intranet,
bbb."res_domain_id" AS res_domain_id
FROM
(
SELECT
md5( concat ( dev."dev_core_ipv4", sec."safe_name" ) ) AS id,
dev."dev_core_ipv4" AS ip,
CASE
WHEN sec."safe_name" IS NULL THEN
'未知安全域' ELSE sec."safe_name"
END AS security_domain_name,
'中国' AS country,
dev."dev_owner_area" AS area,
CASE
            WHEN org."longitude_latitude" IS NOT NULL THEN
                org."longitude_latitude"
            WHEN org."longitude_latitude" IS NULL AND dev."dev_owner_area" IS NOT NULL THEN
                ( SELECT bbb_1."longitude_latitude" FROM "ASSET"."asset_device" aaa INNER JOIN "ASSET"."dmss_area" bbb_1 ON aaa."dev_owner_area"  = bbb_1."area"  LIMIT 1 ) ELSE NULL
END AS longitude_latitude,
CASE

Copy
			WHEN sec."safe_type" = 1 THEN 1
			WHEN sec."safe_type" = 2 THEN	0 ELSE 2
END AS is_intranet,
sec."res_domain_id"
FROM
"ASSET"."asset_device" dev
LEFT JOIN "ASSET"."asset_organization" org ON dev."org_id" = org."id"
LEFT JOIN "A

2. To view the field names in the corresponding view, use sql as follows:

 SELECT COLUMN_NAME
FROM USER_TAB_COLUMNS
WHERE TABLE_NAME = 'ip_area_view'

The result is as follows:

 all in uppercase

3. Use "" to adjust the field output as follows:

CREATE OR REPLACE VIEW "ASSET"."ip_area_view"
AS
SELECT
	bbb."id" ,
	bbb."ip",
	bbb."security_domain_name",
	bbb."country",
	bbb."area",
	SUBSTRING (
		SUBSTRING ( bbb."longitude_latitude" FROM 1 FOR POSITION ( ' ' IN bbb."longitude_latitude" ) - 1 ) 
	FROM
		POSITION ( '经' IN SUBSTRING ( bbb."longitude_latitude" FROM 1 FOR POSITION ( ' ' IN bbb."longitude_latitude" ) - 1 ) ) + 1 
	) AS "longitude",
	SUBSTRING (
		SUBSTRING ( bbb."longitude_latitude" FROM POSITION ( ' ' IN bbb."longitude_latitude" ) + 1 ) 
	FROM
		POSITION ( '纬' IN SUBSTRING ( bbb."longitude_latitude" FROM POSITION ( ' ' IN bbb."longitude_latitude" ) + 1 ) ) + 1 
	) AS "latitude",
	bbb."is_intranet",
	bbb."res_domain_id" 
FROM
	(
	SELECT
		md5( concat ( dev."dev_core_ipv4", sec."safe_name" ) ) AS "id",
		dev."dev_core_ipv4" AS "ip",
	CASE
			
			WHEN sec."safe_name" IS NULL THEN
			'未知安全域' ELSE sec."safe_name" 
		END AS "security_domain_name",
		'中国' AS "country",
		dev."dev_owner_area" AS "area",
	CASE
			
			WHEN org."longitude_latitude" IS NOT NULL THEN
			org."longitude_latitude" 
			WHEN org."longitude_latitude" IS NULL 
			AND dev."dev_owner_area" IS NOT NULL THEN
				( SELECT bbb_1."longitude_latitude" FROM "ASSET"."asset_device" aaa INNER JOIN "ASSET"."dmss_area" bbb_1 ON aaa."dev_owner_area" = bbb_1."area" LIMIT 1 ) ELSE NULL 
				END AS "longitude_latitude",
		CASE
				
				WHEN sec."safe_type" = 1 THEN
				1 
				WHEN sec."safe_type" = 2 THEN
				0 ELSE 2 
			END AS "is_intranet",
			sec."res_domain_id" AS "res_domain_id"
			
		FROM
			"ASSET"."asset_device" dev
			LEFT JOIN "ASSET"."asset_organization" org ON dev."org_id" = org."id"
		LEFT JOIN "ASSET"."asset_safety_margin" sec ON dev."safety_margin_id" = sec."id" 
	) bbb;
