在PostgreSQL數據庫中有一列為JSON,要獲取JSON中得數據可以用下面sql：

select orderno as OrderNo
,amount as Amount
,ordertime as OrderTime
, recordtype as RecordType
from jsonb_to_recordset(( –特定方法
select array_to_json(array_agg(data)) –轉換成一個數組
from wallet_details
where id = @id
)::jsonb) as x(orderno text, amount numeric(16, 6), ordertime text, recordtype varchar(32));
