我有table

Name           Null?    Type         
-------------- -------- ------------ 
PONO           NOT NULL NUMBER(5)    
REQUESTOR               VARCHAR2(50) 
COSTCENTER              VARCHAR2(5)  
ADDRESSSTREET           VARCHAR2(50) 
ADDRESSCITY             VARCHAR2(50) 
ADDRESSSTATE            VARCHAR2(2)  
ADDRESSZIP              VARCHAR2(10) 
ADDRESSCOUNTRY          VARCHAR2(50) 
AD_INFO                 VARCHAR2(50)

以及此类插入

INSERT INTO purchaseorder
      SELECT * FROM json_table(L_PO  FORMAT JSON, '$'
         COLUMNS (
           PONo            Number    PATH '$.PONumber',
           Requestor       VARCHAR2  PATH '$.Requestor',
           CostCenter      VARCHAR2  PATH '$.CostCenter',
           AddressStreet   VARCHAR2  PATH '$.Address.street',
           AddressCity     VARCHAR2  PATH '$.Address.city',
           AddressState    VARCHAR2  PATH '$.Address.state',
           AddressZip      VARCHAR2  PATH '$.Address.zipCode',
           AddressCountry  VARCHAR2  PATH '$.Address.country'));

如果您的表源\u表包含l\u po（json文件），那么您可以使用：

INSERT INTO purchaseorder
      SELECT sc.AD_INFO,jtbl.* FROM source_table sc,json_table(L_PO  FORMAT JSON, '$'
         COLUMNS (
           PONo            Number    PATH '$.PONumber',
           Requestor       VARCHAR2  PATH '$.Requestor',
           CostCenter      VARCHAR2  PATH '$.CostCenter',
           AddressStreet   VARCHAR2  PATH '$.Address.street',
           AddressCity     VARCHAR2  PATH '$.Address.city',
           AddressState    VARCHAR2  PATH '$.Address.state',
           AddressZip      VARCHAR2  PATH '$.Address.zipCode',
           AddressCountry  VARCHAR2  PATH '$.Address.country')) jtbl;
