mysql 创建程序时出错

Question

create procedure temp (in empId int)
begin
 declare emptype varchar;
    select emptype = qoute(emptype) from dms_document where id =  empid;
    select emptype

 case  
when emptype = 'P' then
    select doctype from dms_report where pilot = 1
else
select 'No Documents required'
end case
end;

这是我在 MySQL 中创建过程的查询，我在 case 语句中收到错误请帮助我为什么会出现此错误如何声明 case 语句为什么会在 workbench 中出现错误创建过程

Answer 1

你漏了逗号。

    CREATE PROCEDURE temp (IN empId INT)
        BEGIN
         DECLARE emptype VARCHAR;
            SELECT emptype = qoute(emptype) FROM dms_document WHERE id =  empid;
                SELECT emptype,

     CASE  
    WHEN emptype = 'P' THEN doctype;

    ELSE 'No Documents required';
    END CASE ;
    FROM dms_report WHERE pilot = 1
End;

Answer 2

这里我格式化了你的程序使用delimiter

DELIMITER //
CREATE PROCEDURE temp ( empId INT)
    BEGIN
     DECLARE var_etype VARCHAR(36);

SELECT 
    emptype = QOUTE(emptype)
FROM
    dms_document
WHERE
    id = empid;
SELECT 
    emptype,
    CASE
        WHEN emptype = 'P' THEN doctype
        ELSE 'No Documents required'
    END
FROM
    dms_report
WHERE
    pilot = 1;
End//
DELIMITER ;
