在MySQL亚马逊rds中超出锁超时
我有一个存储过程，这是在一个表中进行保存操作。 在这个存储过程中，我在表中插入多个logging。
这是我的表结构
Table : InviteMst ~~~~~~~~~~~~~~~~~ Name DataType Description -------- ------------ ---------------------- InviteID Int PrimaryKey (Auto Incr) Date Date UserID Int (ForignKey) EMailID varchar(50) Guid varchar(36) store procedure : usp_InviteMst ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ CREATE PROCEDURE `usp_InviteMst`( IN n_UserID INT, IN EmailList MEDIUMTEXT ) BEGIN DECLARE d_Date DATETIME DEFAULT NOW(); IF LENGTH(EmailList) > 0 THEN SET @sqlQuery = ""; SET nPos = INSTR(EmailList, ","); WHILE (nPos <> 0) DO SET c_EmailID = TRIM(SUBSTRING(EmailList, 1,nPos - 1)); IF c_EmailID <> "" THEN SET c_Guid = ""; //Here I am checking that If User already exists with same emailid in same date or note. SELECT Guid INTO c_Guid FROM InviteMst WHERE UserID = n_UserID AND Date = DATE(d_Date) AND Guid IS NOT NULL AND EMailID = c_EmailID ORDER BY Date DESC LIMIT 0, 1; SET c_Guid = COALESCEc_Guid ,""); IF (c_Guid = "") THEN SET c_Guid = UUID(); //Here I am preparing statement/query for insert SET @sqlQuery = CONCAT(@sqlQuery, IF(LENGTH(@sqlQuery) > 0,",",""), "(", n_UserID, ", '", d_Date, "','", c_EmailID, "', c_GuID, "') "); END IF; END IF; SET EmailList = SUBSTRING(EmailList, nPos +1, LENGTH(EmailList)); SET nPos = INSTR(EmailList, ","); END WHILE; IF (LENGTH(@sqlQuery) > 0) THEN //Finally here I am inserting in table SET @sqlQuery = CONCAT("INSERT INTO InviteMst ( UserID, Date, EmailID, Guid ) VALUES ", @sqlQuery); PREPARE stmt FROM @sqlQuery; EXECUTE stmt; SET @sqlQuery = ""; END IF; END IF; END 我打电话给这样的商店程序：
call usp_InviteMst( 1, 'a@a.com,b@b.com,c@c.co.in,g@yahoo.com' );
它正在工作完善，在可能的情况下，但有一段时间（在我的现场项目）它打折错误“锁超时超时”。 我的'innodb_lock_wait_timeout'被设置为100。
如果有更好的办法做到这一点。 或者如何在单个请求中插入多个logging。
我正在使用node.js，现在正在使用事务。
