#. 동일한 구조의 테이블 또는 다른 구조의 테이블에 select 한 내용을 insert 하는 방법

\n

1. select 한 내용의 전체 컬럼 insert

\n\n

2. 원하는 컬럼만 select 해서 insert

\n\n

#. 조건에 따라 값을 지정해주는 Case 문

\n

1. 여러 조건 비교

\n
//Case\n//    WHEN 조건1 THEN 출력1 \n//    WHEN 조건2 THEN 출력2\n//    ELSE 출력3\n//END\n\nSELECT \n    case \n        when sal >=0 and sal <= 1000 then 'E'\n        when sal > 1000 and sal <= 2000 then 'D'\n        when sal > 2000 and sal <= 3000 then 'C'\n        when sal > 3000 and sal <= 4000 then 'B'\n        when sal > 4000 and sal <= 5000 then 'A'\n    end as sal_rank \nFROM table_name;
\n
\n

2. 특정 컬럼의 값으로 비교

\n
//Case 컬럼명\n//    WHEN 값1 THEN 출력1 \n//    WHEN 값2 THEN 출력2\n//    ELSE 출력3\n//END\n\nSELECT \n    case department\n        when 'back-end' then 'BE'\n        when 'front-end' then 'FE'\n        when 'user-interface' then 'UI'\n        else 'ETC'\n    end as department_alias \nFROM table_name;
\n

#. 작업내용

변경사항이 없는 테이블의 경우

\n
insert into autocrypt_v2g_prod.table_name \nselect * from autocrypt_v2g_1208.table_name order by created\n;
\n
\n

CA_CERT 테이블 Migration

\n\n
insert into autocrypt_v2g_prod.ca_cert\n\t(created, created_by, updated, updated_by,\n\tactor, cert, not_after, not_before, serial, subject_dn, ak_id, sk_id, path_length, provider_id, \n\t\n\twca_id,\n\t\n\tvalid,\n\tlast_issued,\n\t\n\tissuer_id )\nselect\n\ts.created, '' as created_by, s.updated, '' as updated_by,\n\ts.actor, s.cert, s.not_after, s.not_before, s.serial, s.subject_dn, s.ak_id, s.sk_id, s.path_length, s.provider_id,\n\t\n    s.id as wca_id,\n\t\n\tcase s.status when 'VALID' then true else false end as valid ,\n\tcase s.last_issued when '1' then true else false end as last_issued,\t\n\t\n    NULL as issuer_id\nfrom autocrypt_v2g_1208.ca_cert s order by s.created\n;\n\nupdate \nautocrypt_v2g_prod.ca_cert target,\n(select\n\ts.id as id,\n\t(select t.id from autocrypt_v2g_prod.ca_cert t where t.wca_id = s.issuer_id) as issuer_id\nfrom autocrypt_v2g_1208.ca_cert s order by s.created) result\nset target.issuer_id = result.issuer_id\nwhere target.wca_id = result.id\n;
\n
\n

값이 잘못 들어 갔을 경우 id의 sequence 까지 (autoincrement) 초기화 하기 위해 truncate문 사용

\n
truncate autocrypt_v2g_prod.tableName;
