mysql - mysql创建过程时出错

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

这是我的查询，我正在 MySQL 中创建过程，我在 case 语句中遇到错误，请帮助我为什么会出现此错误如何声明 case 语句为什么在创建过程的工作台中出现错误

你漏掉了逗号。

    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;
