在MySQL中1行

Question

創建功能我已經創建功能：

CREATE FUNCTION `push_admin`(`p_messenger` text, `p_admin_id` int(20), `p_client_id` int(20)) 
RETURNS INTEGER 
BEGIN 
    INSERT INTO messenger(admin_id, client_id, messenger) 
     VALUES (p_admin_id, p_client_id, p_messenger); 
    INSERT INTO messenger(ref_id) 
     SELECT id FROM messenger WHERE client_id = p_client_id; 
    RETURN LAST_INSERT_ID();  
END$$ 

我怎能捨棄admin_id，client_id，messenger，ref_id爲1行？

Answer 1

在你的phpmyadmin例程中你已經添加了這個函數，你將會找到一個添加參數的選項。見下圖 -

Answer 2

此選項會適合你？

INSERT INTO messenger(admin_id, client_id, messenger, ref_id) 
VALUES (p_admin_id, p_client_id, p_messenger, (SELECT id FROM messenger WHERE client_id = p_client_id)); 

Answer 3

在圖像 爲2行。我需要1行中的admin_id，client_id，messenger，ref_id。韓國社交協會。

Answer 4

在第二個查詢替換INSERT到REPLACE

CREATE FUNCTION `push_admin`(`p_messenger` text, `p_admin_id` int(20), `p_client_id` int(20)) 
RETURNS INTEGER 
BEGIN 
    INSERT INTO messenger(admin_id, client_id, messenger) 
     VALUES (p_admin_id, p_client_id, p_messenger); 
    REPLACE INTO messenger(ref_id) 
     SELECT id FROM messenger WHERE client_id = p_client_id; 
    RETURN LAST_INSERT_ID();  
END$$ 

這將幫助你？

REPLACE與INSERT完全相同，只是如果表中的舊行與PRIMARY KEY或UNIQUE索引的新行具有相同的值，則在插入新行之前刪除舊行。

事實上，他想這樣：

CREATE FUNCTION `push_client`(`p_email` text, `p_messenger` text, `p_phone` text, `p_domain` text, `p_ip` text, `p_browser` text, `p_admin_id` int(20), `p_client_id` int(20)) 
RETURNS INTEGER 
BEGIN 
    SET @id = 0; 

    SELECT id INTO @id FROM messenger WHERE client_id = p_client_id AND admin_id = p_admin_id; 

    INSERT INTO client(ref_id, email, phone, ip, browser) 
     VALUES(@id, p_email, p_phone, p_ip, p_browser); 

    UPDATE client SET domain_id = (SELECT id FROM domain WHERE name = p_domain); 

    INSERT INTO messenger(client_id) 
     SELECT id FROM client WHERE id = p_client_id; 

    UPDATE messenger 
    SET admin_id = p_admin_id, browser = p_browser, messenger = p_messenger 
    WHERE client_id = p_client_id; 

    RETURN LAST_INSERT_ID();  
END$$
