php - 存储过程 phpmyadmin

Question

我想在mysql phpmyadmin中写一个程序。 程序如下:

create procedure insert_villa (IN $mtid int,IN $ctid 
int,IN $pro varchar(100),IN $city 
   varchar(100))
   begin

  //variable declare here
   declare $mtid int;
   declare $ctid int;
   declare $pro varchar(100);
   declare $city varchar(100);

   //setting variables
   set @mtid = ($mtid);
   set @ctid   = ($ctid );
   set @pro      = ($pro) ;
   set @city    = ( $city);

 // insert statement 
"INSERT INTO `melk`(`melktypeid`, `contracttypeid`,`province`,`city`)
 VALUES (mtid,ctid,pro,city)";
END//  

它显示如下错误: SQL查询:

CREATE PROCEDURE insert_villa( IN $mtid int, IN $ctidint, IN $pro varchar( 100 ) , IN $cityvarchar( 100 ) ) BEGIN //

MySQL 说:文档

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4

这是我第一次使用程序。我对此不太了解。请帮助我。

Answer 1

您的程序可以归结为这样

CREATE PROCEDURE insert_villa (IN _mtid INT, IN _ctid INT,  IN _pro VARCHAR(100), IN _city VARCHAR(100))
  INSERT INTO melk (melktypeid, contracttypeid, province, city)
  VALUES (_mtid, _ctid, _pro, _city);

使用示例:

CALL insert_villa(1, 1, 'Province1', 'City2');
