将oracle表字段json字符串分解提取并返回单列表

oracle 版本

11gR2(11.2.0.4.0)

原始表字段内容


{"FRAME_INFO": ["0,0,-1,1800,1800,5992,191,20","1,0,-1,2000,1800,5992,188,20","2,0,-1,1800,1800,5992,182,20","3,0,-1,1800,1800,5992,177,20","4,0,-1,3700,1800,6005,171,20","5,0,-1,19200,1800,5992,167,20","6,0,-1,12000,1800,6005,163,20","7,0,-1,6200,1800,6005,159,20","8,0,-1,4700,1800,6005,154,20","9,0,-1,9900,1800,6005,150,20","10,0,-1,6500,1800,5992,147,20"],"PLAY_IDX": ["0,4,6,4","1,4,6,4","2,5,6,5","3,5,6,5","4,5,7,5","5,5,7,5","6,6,7,5","7,6,8,5","8,6,8,5","9,6,8,6","10,7,8,6","5,5,7,5"],"IRV_NUM": 11,"VI_NUM": 13,"OVA_NUM": 15,"OVB_NUM": 0,"IRV_DIR": "20250708000540_1_CRH2A-2229_720_0_B","VI_DIR": "20250708000540_2_CRH2A-2229_720_0_B_M","OVA_DIR": "20250708000540_3_CRH2A-2229_720_0_B","OVB_DIR": "20250708000540_4_CRH2A-2229_720_0_B","START_IDX": 1,"FAULT_IDX": 5,"VI_IDX": 5,"OVA_IDX": 7,"OVB_IDX": 5,"FLAG": [0,0,0,0]
}

需求是将FRAME_INFO部分每行提取出来

提取FRAME_INFO部分


regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'

提取每一行


TABLE( --CAST( --  MULTISET --(SELECT regexp_substr(regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'), '\d[^"]+', 1, LEVEL)FROM dualCONNECT BY regexp_substr(regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'), '\d[^"]+', 1, LEVEL) IS NOT NULL --   ) --AS SYS.ODCIVARCHAR2LIST)) t

实现完整SQL


SELECT ID, t.* --regexp_substr(regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'), '\d[^"]+', 1, 3)   FROM alarm a,TABLE( --CAST( --  MULTISET --(SELECT regexp_substr(regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'), '\d[^"]+', 1, LEVEL)FROM dualCONNECT BY regexp_substr(regexp_substr(a.svalue3, '"FRAME_INFO":[^]]+'), '\d[^"]+', 1, LEVEL) IS NOT NULL --   ) --AS SYS.ODCIVARCHAR2LIST)) tWHERE a.raised_time > TRUNC(SYSDATE)AND a.status = 'AFSTATUS03'AND a.id = 'F060ee2f14b7942d88b01832551a457d2';

验证查询结果
