mysql error code '1064' 排查過程

標籤：

     下午自測代碼，在這個update上卡了一個半小時，大大的降低了開發的生產力，把排查過程發出來，好計程車兵不會掉進同一個陷阱。先把異常堆棧打出來。

    還有我的Ibatis的SQL

<update id="updateById"  parameterClass="Org">UPDATE orgSETname = #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>

    像這種堆棧沒有明確指明原因的sql問題，排查問題肯定是根據error code去查。百度了下這個1064 error code。說是表的列名跟Mysql的關鍵字重疊了。OK，我把這個sql貼近mysql用戶端的查詢介面，發現name欄位變成了關鍵字的顏色。我以為找到問題了，於是把name前後加反引號。再跑下單元測試，依然報1064錯誤。

    沒轍，只能把ibatis的執行的sql打出來，放進mysql用戶端看看。OK，log4j加日誌，把ibatis的執行sql打出來。再跑一遍單元測試，sql並沒有打出來。

    有種叫天天不應叫地地不靈的沮喪感！

    沒辦法，只能肉眼看sql。如果editor欄位為null，那麼where前面就多個多餘的逗號了。調整下sql。

<update id="updateById"  parameterClass="Org">UPDATE orgSET 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` + 1WHERE id = #id#</update>

    在跑下單元測試，sql成功的執行。mysql的error code一點都不靠譜！明明是sql文法有問題，卻報1064的code。

    把name和version欄位上的反引號去掉，sql依然可以正常的執行。吐槽！
