Question

任何人都可以帮我解释为什么我无法在存储过程中创建临时表。

这是我的存储过程脚本

DELIMITER $$

DROP PROCEDURE IF EXISTS getProductionItem$$
CREATE DEFINER=pvtuser@`%` PROCEDURE getProductionItem(projectID BIGINT(20))


BEGIN

  CREATE TEMPORARY TABLE tempProdItem(
    prodType SET('JOB','BATCH','DOCGROUP'),
    taskQueueId BIGINT(20),
    jobBatchDocId BIGINT(20),
    jobBatchDocName VARCHAR(255),
    lockStatus SET('LOCKED','OPEN')
  );


  DECLARE done INT DEFAULT 0;


  DECLARE prodType VARCHAR(10);
  DECLARE taskQueueId BIGINT(20);
  DECLARE jobBatchDocId BIGINT(20);
  DECLARE jobBatchDocName VARCHAR(255);
  DECLARE lockStatus VARCHAR(10);


  DECLARE docCursor CURSOR
      FOR SELECT 'DOCGROUP',
                 jq.taskqueueid,
                 jq.documentgroupid,
                 dgd.documentGroupName,
                 COALESCE(jql.lockStatus,'OPEN')
