Question

尝试从存储过程中调用存储的函数时出现1064错误。它只发生在我尝试执行此操作的行上：SET account_id = get_account_id(user);。有什么问题，我该如何解决？

帐户ID存储功能：

CREATE DEFINER=`aaron`@`%` FUNCTION `get_account_id`(user VARCHAR(255)) RETURNS int(11)
BEGIN
    DECLARE xaccount_id INT DEFAULT 0;

   #Get Account ID and place into variable used when calling stored procedure that builds the tree structure for the leaf node portfolio id
    SELECT account_id
    FROM rst_sessions.session_data
    WHERE  username = user
    ORDER BY update_date DESC LIMIT 1
    INTO xaccount_id;

    RETURN xaccount_id;
END

尝试调用存储函数的存储过程：

CREATE DEFINER=`aaron`@`%` PROCEDURE `build_report_portfolio_list`(user VARCHAR(255))
    READS SQL DATA
BEGIN

    DECLARE portf_id INT;
    DECLARE portf_name VARCHAR(255);
    DECLARE str_portf_parent_list VARCHAR(455);
    DECLARE done INT DEFAULT 0;
  DECLARE account_id INT;

  SET account_id = get_account_id(user);
END

我甚至不知道我试图做的是否可能，这可能导致错误。但是我找到了一个解决办法，通过调用SF作为参数来调用SP并让它做我需要它做的事情。

代码是：CALL build_report_portfolio_list(get_account_id('username_here'));
