你能看到這個查詢有什麼問題嗎？

Question

林開發Grails的2.2.4應用程序和使用Groovy，和我有這部分代碼：

def str2= """select to_number(to_date(NEXTRUNTIME,'DD-MON-YYYY') - to_date(LASTRUNTIME,'DD-MON-YYYY')) as DAYS, SUBSTR(to_CHAR(NEXTRUNTIME,'DD-MON-YYYY HH24:MI:SS'),13,8)as Hour from v8_recurtimeevent WHERE to_date(NEXTRUNTIME,'DD-MON-YYYY') != to_date(LASTRUNTIME,'DD-MON-YYYY') AND EVENT_UUID='000001112eae40e3-0000-b517-0a40246b';""" 

  sql.eachRow(str2) 
      { 
         x.date="Days:"+"${it.Days}".toString()+" and hour: "+"${it.Hour}" 
      } 

當我執行它，我得到這個錯誤...能你看到什麼是metter？

Answer 1

def str2= "select to_number(TRUNC(NEXTRUNTIME) - 
          TRUNC(LASTRUNTIME)) as DAYS, 
        SUBSTR(to_CHAR(NEXTRUNTIME,'DD-MON-YYYY HH24:MI:SS'),13,8)as Hour 
      from v8_recurtimeevent 
      WHERE TRUNC(NEXTRUNTIME) != TRUNC(LASTRUNTIME) 
      AND EVENT_UUID='000001112eae40e3-0000-b517-0a40246b'" 

此外，TRUNC（）是你需要什麼！忽略日期中的時間元素！
