创建临时表后缺少“结束”错误答案

【问题标题】：Missing 'end' error after create temporary table创建临时表后缺少“结束”错误
【发布时间】：2018-04-24 05:15:37
【问题描述】：

我正在创建一个存储过程，我应该在其中创建一个临时表来插入数据并在最后显示（这是一个作业，所以我必须按照说明创建临时表）。

我应该在这个存储过程中使用游标。我正在创建临时表，然后我正在创建一个游标。但我在创建表后收到错误missing 'end'。

CREATE DEFINER=`root`@`localhost` PROCEDURE `walkerMasterSummary`()

开始

DECLARE rowCount INT Default 0;
DECLARE counter INT Default 0;
DECLARE WID char(6);
DECLARE WType_WTID varchar(15);
DECLARE WUID char(6);
DECLARE BattleGroup char(5);
DECLARE CubicAreaWeight decimal(10,2);
DECLARE FuelCapacity decimal(10,2);
DECLARE FuelExpenditure_Mile decimal(10,2);
DECLARE ArmorWeight decimal(10,2);
DECLARE StructureWeight decimal(10,2);
DECLARE Status VARCHAR(20);
DECLARE CostToRepair int(10);


DROP temporary table walker_master;

CREATE temporary table walker_master(
    WID char(6),
WType_WTID varchar(15),
WUID char(6),
BattleGroup char(5),
CubicAreaWeight decimal(10,2),

FuelExpenditure_Mile decimal(10,2),
ArmorWeight decimal(10,2),

);

 DECLARE walkerMaster CURSOR FOR
 SELECT IWA.WID, concat(IWA.WalkerType, " - ", IWT.WTypeID) AS WType_WTID

  * IWT.Weight 
    WHEN IWA.Status = 'Damaged' AND IWA.WalkerType = 'AT-ST' THEN 89 * 
  IWT.Weight
        ELSE 0 END AS CostToRepair
 FROM imperial_walkers_assign IWA
 LEFT JOIN imperial_walker_type IWT ON IWA.WalkerType = IWT.WType
 LEFT JOIN walker_units WU ON IWA.WUID=WU.WUID
ORDER BY IWA.WID;

OPEN walkerMaster;
  BEGIN
SELECT Found_Rows() INTO rowCount;
process_loop : loop
 IF counter < rowCount THEN
 FETCH walkerMaster INTO WID ,WType_WTID, WUID, BattleGroup,

/* DROP temporary table walker_summary;
CREATE temporary table walker_summary AS SELECT WID ,WType_WTID,WUID,

 SELECT WID ,WType_WTID, WUID, BattleGroup, CubicAreaWeight, FuelCapacity,
 FuelExpenditure_Mile, ArmorWeight, StructureWeight,Status, CostToRepair;
 SET counter = counter +1;
 ELSE
 leave process_loop;
END IF;
END loop process_loop;
END;
CLOSE walkerMaster;

END

我没有删除临时表或游标的选项。我应该如何解决这个错误？

【问题讨论】：

交换游标的声明和临时表的删除和创建。声明通常出现在任何代码之前。

标签： mysql stored-procedures cursor temp-tables

【解决方案1】：

游标的声明应该在创建临时表之前

我也取消了插入临时表的代码
