mysql的查询sql中使用case的例子

SELECT AC.ACCOUNT_CODE,

CASE

WHEN AC.ACCOUNT_TYPE = 1 THEN 'ASSETS'

WHEN AC.ACCOUNT_TYPE = 2 THEN 'LIABILITIES'

WHEN AC.ACCOUNT_TYPE = 4 THEN 'EQUITY'

ELSE 'GAIN/LOSS'

END ACCOUNT_TYPE,

IF(AC.CODE_TYPE = 0,'HEADER','DETAIL') AS CODE_TYPE,

IF(AC2.NAME IS NULL, 'NONE', AC2.NAME) PARENT_ID_NAME, AC.`NAME`, AC.OTHER_NAME

FROM T_FIN_ACCOUNTING_CODE AC

LEFT JOIN T_FIN_ACCOUNTING_CODE AC2 ON AC2.ACCOUNT_ID = AC.PARENT_ID

ORDER BY AC.ACCOUNT_CODE, AC.`NAME` ;
