Case Study

컬럼 크기 변경(TOTAL_SIZE, USED_SIZE, NAME)

ALTER TABLE T_LOG_SYSTEM ALTER COLUMN TOTAL_SIZE VARCHAR(32) NOT NULL;
ALTER TABLE T_LOG_SYSTEM ALTER COLUMN USED_SIZE VARCHAR(32) NOT NULL;
ALTER TABLE T_LOG_SYSTEM ALTER COLUMN NAME VARCHAR(64);

컬럼 추가(INFLOW)

ALTER TABLE T_ADDON_TOPKEYWORD ADD COLUMN INFLOW VARCHAR(64) DEFAULT '';
UPDATE T_ADDON_TOPKEYWORD SET INFLOW='inflow' WHERE INFLOW IS NULL;
 
ALTER TABLE T_ADDON_TOPKEYWORD_EXCEPT ADD COLUMN INFLOW VARCHAR(64) DEFAULT '';
UPDATE T_ADDON_TOPKEYWORD_EXCEPT SET INFLOW='inflow' WHERE INFLOW IS NULL;

인덱스(INDEX) 추가, 조회

CREATE INDEX {인덱스명} ON {테이블명} ({컬럼명})
-- 예시(온나라) --
CREATE INDEX TB_BMS_DCT_ENF_2021_IDX ON PUBLIC.TB_BMS_DCT_ENF_2021 (DOCID,ENFDOCID);
CREATE INDEX TB_BMS_DCT_ENF_2021_DOCID_IDX ON PUBLIC.TB_BMS_DCT_ENF_2021 (DOCID);
CREATE INDEX TB_BMS_DCT_ENF_2021_ENFDOCID_IDX ON PUBLIC.TB_BMS_DCT_ENF_2021 (ENFDOCID)
 
-- 인덱스 조회
SELECT * FROM information_schema.CONSTRAINTS c WHERE TABLE_SCHEMA = 'PUBLIC' AND TABLE_NAME='{테이블명}'
OR
SELECT * FROM INFORMATION_SCHEMA.INDEXES WHERE TABLE_NAME ='{테이블명}';
