Mysql stored procedure gives unknown column error when executed [duplicate]

问题

I have written a small stored procedure to store redmine issue and timelog entries in my private redmine. The procedure is stored, but when I call it, it gives SQL error (1054): Unknown column 'uid' in 'field list' error. The column that the error message mention is exists, the type matches.

Rewrite code, redeploy db

When the second insert removed from SP, it works great.

delimiter $$
DROP PROCEDURE if exists redmine.insert_fingerprint_workday_and_hour $$

CREATE DEFINER=`root`@`%` PROCEDURE `insert_fingerprint_workday_and_hour`(
    IN `userid` INT(11) )

set @uid=userid;

INSERT INTO issues (

  );

  set @ujissue=LAST_INSERT_ID();

  insert into time_entries 
  (project_id,user_id,issue_id,hours,activity_id,spent_on,tyear,tmonth,tweek,created_on,updated_on)
  values
  (
  "1",                      -- project_id

  week(now()),              -- tweek
  now(),                        -- created_on
  now()
  );

  END $$

  DELIMITER ;

SQL> CALL redmine.insert_fingerprint_workday_and_hour('7');
/* SQL error (1054): Unknown column 'uid' in 'field list' */

The only input is a number, a user_id. The code should add an issue to a project and log 8 workhours. The first insert adds the issue to the project and a second logs the hours.

After hours of debugging I cannot figure out what can be the problem.

All advice is welcome!

Thanks, Peter

In MySQL, variables with the @ sigil are session variables, not local variables. Session variables are different from local variables, even if they have the same name other than the @ sigil.
