正確的語法爲MySQL 5存儲過程？

Question

這是MySQL 5.x存儲過程的正確語法嗎？

DELIMITER $$ 

CREATE PROCEDURE GetNearbyPhotogsByMapCenter(
    lat1 decimal (7,3), 
    long1 decimal (7,3), 
    range numeric (15) 
) 
BEGIN 
DECLARE rangeFactor decimal (7,6); 
SET rangeFactor = 0.014457; 
select * from (
    SELECT B.cb_plug_lat, B.cb_plug_lng, B.cb_photostudio , B.city, B.State, 
    B.country, B.website, B.cb_basesserved, B.phone, 
    B.cb_isrc,B.cb_isavailableforsessions 
    FROM jos_comprofiler AS B, jos_users as JU 
    WHERE 
    B.cb_plug_lat BETWEEN lat1-(range*rangeFactor) AND 
    lat1+(range*rangeFactor) 
    AND B.cb_plug_lng BETWEEN long1-(range*rangeFactor) AND 
    long1+(range*rangeFactor) 
    AND GetDistance(lat1,long1,B.cb_plug_lat,B.cb_plug_lng) <= range 
    AND B.approved = 1 
    AND B.confirmed = 1 
    AND B.user_id = JU.id 
    ORDER BY B.cb_isrc desc) as D 
    WHERE D.cb_isavailableforsessions = 'Yes' or D.cb_isavailableforsessions is null; 
END

我想這個存儲過程加載到使用我的phpMyAdmin的SQL選項卡，我的MySQL數據庫。我沒有設置分隔符在該選項卡底部的$$按照這個帖子： How do I write an SP in phpMyAdmin (MySQL)?

所以我只是好奇，爲什麼我不斷收到此錯誤：

#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 'lat1 decimal (7,3), long1 decimal (7,3), range numeric (15) BEGIN ' at line 2 

Answer 1

不要把程序標識符插入引號。另外range是一個MySQL保留字（自5.1開始），因此您每次使用它時都需要反引號（`），或者將其更改爲非保留字。

下面是沒有註冊我的MySQL 5.2服務器上的程序

CREATE PROCEDURE GetNearbyPhotogsByMapCenter(
    lat1 decimal (7,3), 
    long1 decimal (7,3), 
    `range` numeric (15) 
) 
BEGIN 
DECLARE rangeFactor decimal (7,6); 
SET rangeFactor = 0.014457; 
select * from (
    SELECT B.cb_plug_lat, B.cb_plug_lng, B.cb_photostudio , B.city, B.State, 
    B.country, B.website, B.cb_basesserved, B.phone, 
    B.cb_isrc,B.cb_isavailableforsessions 
    FROM jos_comprofiler AS B, jos_users as JU 
    WHERE 
    B.cb_plug_lat BETWEEN lat1-(`range`*rangeFactor) AND 
    lat1+(`range`*rangeFactor) 
    AND B.cb_plug_lng BETWEEN long1-(`range`*rangeFactor) AND 
    long1+(`range`*rangeFactor) 
    AND GetDistance(lat1,long1,B.cb_plug_lat,B.cb_plug_lng) <= `range` 
    AND B.approved = 1 
    AND B.confirmed = 1 
    AND B.user_id = JU.id 
    ORDER BY B.cb_isrc desc) as D 
    WHERE D.cb_isavailableforsessions = 'Yes' or D.cb_isavailableforsessions is null; 
END
