Php mysqli适用于sql但不适用于存储过程

Question

$table = "alabama";

$sql = "SELECT distinct zip FROM {$table} where zip is not null order by zip;";
$sql .= "SELECT distinct city FROM {$table} where city is not null order by city;";
$sql .= "SELECT distinct county FROM {$table} where county is not null order by county;";

$mysqli = new MySQLI('host','user','pass','db');
if ($mysqli->multi_query($sql)) {
       do {
        if ($result = $mysqli->store_result()) {
            while ($row = $result->fetch_row()) {
                 echo($row[0]);
            }
            $result->close();
        }
        if ($mysqli->more_results()) {
            echo ("next result");
        }
    } while ($mysqli->next_result());
}
$mysqli->close();

上面的工作原理很好，现在的问题是在存储过程中使用了相同的sql（经过测试的存储过程在命令行中运行良好）。 如果我将sql字符串替换为

$sql = "CALL {$table}_zip();";
$sql .= "CALL {$table}_city();";
$sql .= "CALL {$table}_county();";

则以上脚本不会给出结果。

我什至用单个存储过程调用它都没有给出结果的测试。

检查在mysql数据库中为procs_priv列授予的特权-> http://dev.mysql.com/doc/refman/5.1/en/grant-table-structure.html

Answer 2

我已经敲了一个简单但功能丰富的示例（不包括参照完整性），您可能会发现...

PHP

调用单个存储过程将返回多个结果集。 您当然可以只调用3个独立的存储过程。

<?php

$conn = new Mysqli("localhost", "foo_dbo", "pass", "foo_db");

$result = $conn->query(sprintf("call list_state_counties_cities(%d)", 1));
$row = $result->fetch_assoc();
echo $row["name"], "<br/>";

$conn->next_result();
$result = $conn->use_result();

while($row = $result->fetch_assoc()) echo $row["county_id"], "<br/>";

$conn->next_result();
$result = $conn->use_result();

while($row = $result->fetch_assoc()) echo $row["city_id"], "<br/>";

$result->close();   
$conn->close();

?>

SQL脚本

-- TABLES

drop table if exists states;
create table states
(
state_id tinyint unsigned not null auto_increment primary key,
name varchar(255) unique not null,

drop table if exists counties;
create table counties

drop table if exists cities;
create table cities

-- TRIGGERS

delimiter #

for each row
begin
  update states set county_counter = county_counter+1 where state_id = new.state_id;
end#

create trigger cities_before_ins_trig before insert on cities

  select state_id into v_state_id from counties where county_id = new.county_id;
  set new.state_id = v_state_id;

    update counties set city_counter = city_counter+1 where county_id = new.county_id;
end#

delimiter ;

-- STORED PROCEDURES

drop procedure if exists list_state_counties_cities;
delimiter #

create procedure list_state_counties_cities
(
in p_state_id tinyint unsigned
)
begin
    -- return multiple resultsets !!
    select * from states where state_id = p_state_id;
    select * from counties where state_id = p_state_id order by name;
    select * from cities where state_id = p_state_id order by name;
end #

delimiter ;

-- TEST DATA

insert into states (name) values ('state1'),('state2');

insert into counties (state_id, name) values 
(1,'county1'),(1,'county2'),(1,'county3'),
(2,'county4'),(2,'county5');

insert into cities (county_id, name) values
(1,'city1'),(1,'city2'),(1,'city3'),
(2,'city4'),(2,'city5'),
(3,'city6'),(3,'city7'),(3,'city8'),
(4,'city9'),(4,'city10'),
(5,'city11');

-- TESTING

select * from states;
select * from counties;
select * from cities;

call list_state_counties_cities(1);

希望这可以帮助您指出正确的方向:)
