異常排查

XML中是這樣寫的

<sql id="failureRequestValue">
        #{ID, jdbcType=NUMBER},
        #{CURRENT_DATE, jdbcType=VARCHAR},
        #{CURRENT_HOUR, jdbcType=NUMBER},
        #{CURRENT_MIN, jdbcType=NUMBER},
        #{ERROR_MESSAGE, jdbcType=VARCHAR}      
</sql>

但是查閱官方文件，發現Mybatis中jdbcType整形應該為NUMERIC，並沒有所謂的oracle中的整形NUMBER，所以這點應該記住。

<sql id="failureRequestValue">
        #{id, jdbcType=NUMERIC},
        #{current_date, jdbcType=VARCHAR},
        #{current_hour, jdbcType=NUMERIC},
        #{current_min, jdbcType=NUMERIC},
        #{error_message, jdbcType=VARCHAR}      
</sql>

上述錯誤導致的原因在於Mybatis的jdbcType型別沒有弄清楚，Mybatis中數值用NUMERIC，而不是oracle中的NUMBER。
