mysqlのストアドプロシージャ

Question

私は、テーブルpanel_userに行を挿入するには、以下のストアドプロシージャを作成しました：

CREATE PROCEDURE panel_users() 
BEGIN 
DECLARE i INTEGER; 
DECLARE user_id BIGINT(20); 
DECLARE panel_id BIGINT(20); 
DECLARE wt DECIMAL(10,6); 
DECLARE level DECIMAL(6,2); 
DECLARE total INTEGER; 
SET i=1; 
SELECT COUNT(*) INTO total FROM smartmeter_usage.users_reporting; 
WHILE i<=total DO 
    SELECT u.userId INTO user_id, p.panelId INTO panel_id, ur.usage_percent INTO level, ipr.wt_base INTO wt 
    FROM mondrainusage.user_d u 
    INNER JOIN smartmeter_usage.imei_phone_reporting ipr ON u.imeiNumber = ipr.IMEI 
    INNER JOIN smartmeter_usage.users_reporting ur ON ur.mobile_number = ipr.mobile_number 
    INNER JOIN smartmeter_usage.panel pn ON pn.panel_id = ur.panel_id 
    INNER JOIN mondrainusage.panel p ON p.panelName = pn.panel_name 
    WHERE u.userId = i; 
    INSERT INTO mondrainusage.panel_user (panelId, userId, userWeight, usageLevel) VALUES(panel_id, user_id, wt, level); 
    SET i = i+1; 
END WHILE 
END 

私は、次のようなエラーになっています：

Undeclared variable: p 

を私がここで間違っているものを得るわけではありません私の質問。そこから道がありますか？

EDIT：

K Iは、上記の問題の解決策を得ました。

CREATE PROCEDURE panel_users() 
BEGIN 
DECLARE i INTEGER; 
DECLARE user_id BIGINT(20); 
DECLARE panel_id BIGINT(20); 
DECLARE wt DECIMAL(10,6); 
DECLARE level DECIMAL(6,2); 
DECLARE total INTEGER; 
SET i=1; 
SELECT COUNT(*) INTO total FROM smartmeter_usage.users_reporting; 
WHILE i<=total DO 
    SELECT u.userId, p.panelId, ur.usage_percent, ipr.wt_base INTO user_id, panel_id, level, wt 
    FROM mondrainusage.user_d u 
    INNER JOIN smartmeter_usage.imei_phone_reporting ipr ON u.imeiNumber = ipr.IMEI 
    INNER JOIN smartmeter_usage.users_reporting ur ON ur.mobile_number = ipr.mobile_number 
    INNER JOIN smartmeter_usage.panel pn ON pn.panel_id = ur.panel_id 
    INNER JOIN mondrainusage.panel p ON p.panelName = pn.panel_name 
    WHERE u.userId = i; 
    INSERT INTO mondrainusage.panel_user (panelId, userId, userWeight, usageLevel) VALUES(panel_id, user_id, wt, level); 
    SET i = i+1; 
END WHILE 
END 

ビットは、今ではライン21

で私に「終了」の近くに構文エラーを与えているのはなぜこれがそうである：ここでの解決策はありますか？

EDIT：

ソリューションを手に入れた：ここ

END WHILE; 

Answer 1

が働いたソリューションです。

CREATE PROCEDURE panel_users() 
BEGIN 
DECLARE i INTEGER; 
DECLARE user_id BIGINT(20); 
DECLARE panel_id BIGINT(20); 
DECLARE wt DECIMAL(10,6); 
DECLARE level DECIMAL(6,2); 
DECLARE total INTEGER; 
SET i=1; 
SELECT COUNT(*) INTO total FROM smartmeter_usage.users_reporting; 
WHILE i<=total DO 
    SELECT u.userId, p.panelId, ur.usage_percent, ipr.wt_base INTO user_id, panel_id, level, wt 
    FROM mondrainusage.user_d u 
    INNER JOIN smartmeter_usage.imei_phone_reporting ipr ON u.imeiNumber = ipr.IMEI 
    INNER JOIN smartmeter_usage.users_reporting ur ON ur.mobile_number = ipr.mobile_number 
    INNER JOIN smartmeter_usage.panel pn ON pn.panel_id = ur.panel_id 
    INNER JOIN mondrainusage.panel p ON p.panelName = pn.panel_name 
    WHERE u.userId = i; 
    INSERT INTO mondrainusage.panel_user (panelId, userId, userWeight, usageLevel) VALUES(panel_id, user_id, wt, level); 
    SET i = i+1; 
END WHILE; 
END
