mysql error code '1064' 排查过程
下午自测代码，在这个update上卡了一个半小时，大大的降低了开发的生产力，把排查过程发出来，好的士兵不会掉进同一个陷阱。先把异常堆栈打出来。

还有我的Ibatis的SQL
<update id="updateById" parameterClass="Org"> UPDATE org SET name = #name:VARCHAR#, <isNotNull property="tree_level">tree_level = #tree_level#, </isNotNull> <isNotNull property="yn">yn = #yn#, </isNotNull> <isNotNull property="route">route = #route:VARCHAR#, </isNotNull> `version` = `version` + 1, <isNotNull property="editor">editor = #editor:VARCHAR# </isNotNull> WHERE id = #id# </update>
像这种堆栈没有明确指明原因的sql问题，排查问题肯定是根据error code去查。百度了下这个1064 error code。说是表的列名跟Mysql的关键字重叠了。OK，我把这个sql贴近mysql客户端的查询界面，发现name字段变成了关键字的颜色。我以为找到问题了，于是把name前后加反引号。再跑下单元测试，依然报1064错误。
没辙，只能把ibatis的执行的sql打出来，放进mysql客户端看看。OK，log4j加日志，把ibatis的执行sql打出来。再跑一遍单元测试，sql并没有打出来。
有种叫天天不应叫地地不灵的沮丧感！
没办法，只能肉眼看sql。如果editor字段为null，那么where前面就多个多余的逗号了。调整下sql。
<update id="updateById" parameterClass="Org"> UPDATE org SET id = #id# , <isNotNull property="name">`name` = #name:VARCHAR#, </isNotNull> <isNotNull property="tree_level">tree_level = #tree_level#, </isNotNull> <isNotNull property="yn">yn = #yn#, </isNotNull> <isNotNull property="route">route = #route:VARCHAR#, </isNotNull> <isNotNull property="editor">editor = #editor:VARCHAR# , </isNotNull> `version` = `version` + 1 WHERE id = #id# </update>
在跑下单元测试，sql成功的执行。mysql的error code一点都不靠谱！明明是sql语法有问题，却报1064的code。
把name和version字段上的反引号去掉，sql依然可以正常的执行。吐槽！
