Question

我已经研究了几个小时了（如何从Workbench）在存储的proc内创建一个简单的MySQL游标，但是无论我尝试什么，我总是会收到此错误：

命令不同步；您现在不能运行此命令

这是我存储的proc：

DELIMITER //
DROP PROCEDURE IF EXISTS ApplyNewFormFieldsToExistingPolicies;
CREATE PROCEDURE ApplyNewFormFieldsToExistingPolicies(argAgencyID int)
BEGIN
  DECLARE done INT DEFAULT FALSE;
  DECLARE t AS INT; -- TruckerID
  DECLARE a AS INT; -- AgentID
  DECLARE cursor1 CURSOR FOR SELECT AgentUserID AS AgentID, ID AS TruckerID from Users where IsTrucker = 1 AND AgencyID = argAgencyID
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

  OPEN cursor1;

  read_loop: LOOP
    FETCH cursor1 INTO t, a;

    -- do something with 't'
    -- do something with 'a'

  END LOOP;
  CLOSE cursor1;
END //
DELIMITER ;

此sql有效，并返回预期数据：

SELECT AgentUserID AS AgentID, ID AS TruckerID from Users where IsTrucker = 1 AND AgencyID = 1

有什么想法我做错了吗？

具有简单游标的简单存储过程将无法编译
