我的意思是说我希望属性名称作为列名后跟值数据就像这样（小部分）

<row _id="1" _uuid="0BEBAB70-5985-4A1C-862F-A842BF7F293C" _position="1" _address="http://data.montgomerycountymd.gov/resource/_6rqk-pdub/1">

我需要输出为第一行，作为一列全名为一列

Answer 1

CREATE PROCEDURE dynamic(IN xml_data varchar)
BEGIN
    /* Put your logic and set your sql dynamic from xml_data */
    SET @sql = ...

    PREPARE statement FROM @sql;
    EXECUTE statement;
    DEALLOCATE PREPARE statement;
END

是否可以从xml数据动态生成我的SQL表的列名？
