下面是我的数据，只有一行数据，我需要将其上传到上表中。
1015826235-[{"product_id":220003038067,"timestamps":"1340321132000"},{"product_id":300003861266,"timestamps":"1340271857000"},{"product_id":140002997245,"timestamps":"1339694926000"},{"product_id":200002448035,"timestamps":"1339172659000"},{"product_id":260003553381,"timestamps":"1339072514000"}]-
在我选择查询时上传数据后，我看不到正确的数据。我应该只得到如下一行，但我没有在表中得到下面的结果
**USER_ID** **PURCHASED_ITEM**
1015826235 [{"product_id":220003038067,"timestamps":"1340321132000"}, {"product_id":300003861266,"timestamps":"1340271857000"}, {"product_id":140002997245,"timestamps":"1339694926000"}, {"product_id":200002448035,"timestamps":"1339172659000"}, {"product_id":260003553381,"timestamps":"1339072514000"}]
在我执行选择查询后，我的表数据中得到的不是上面的数据，而是类似这样的数据。分隔符有什么问题吗？
1015826235 [{"product_id":null,"timestamps":" 220003038067"},{"product_id":null,"timestamps":" \"1340321132000\"}"},{"product_id":null,"timestamps":"
300003861266"},{"product_id":null,"timestamps":" \"1340271857000\"}"},{"product_id":null,"timestamps":" 140002997245"},
{"product_id":null,"timestamps":" \"1339694926000\"}"},{"product_id":null,"timestamps":" 200002448035"},
{"product_id":null,"timestamps":" \"1339172659000\"}"},{"product_id":null,"timestamps":" 260003553381"},
{"product_id":null,"timestamps":" \"1339072514000\"}]"}]
谁能指出我做错了什么？
最佳答案
给产品id加上双引号
