我需要在結果打印變量設置

我需要能夠輸入變量轉換爲datetime或標記 - 然後將其發送回設置爲select語句的一部分結果。我已經準備好下面這當然不工作的代碼 - 它向我發送1970-01-01不管UNIX是什麼時候了。這些都是我想發送到結果集的作品：我需要在結果打印變量設置

FROM_UNIXTIME（的startDate，「％Y-％間％d」）AS STARTINGDATE， FROM_UNIXTIME（結束日期，「％Y-％間％d 「）作爲ENDINGDATE

      DECLARE endDate varchar (50); 


      SET startDate = FROM_UNIXTIME(fromDate/1000); 
      SET endDate = FROM_UNIXTIME(toDate/1000);

您必須刪除

SET startDate = FROM_UNIXTIME(fromDate/1000); 
SET endDate = FROM_UNIXTIME(toDate/1000);

因爲Unix時間戳和毫秒的工作，並在您選擇使用作爲

FROM_UNIXTIME(fromDate,"%Y-%m-%d") AS startingDate, 
FROM_UNIXTIME(toDate,"%Y-%m-%d") AS endingDate

這實際上做的工作 - 事實上，原來的查詢工作 - 我將它添加到錯誤的數據庫。

（CONVERT_TZ（（FROM_UNIXTIME（FROM日期/ 1000））， 'UTC'，的timeZone））AS STARTINGDATE，（CONVERT_TZ（（FROM_UNIXTIME（TODATE/1000））， 'UTC'，的timeZone））AS日期ENDINGDATE，
