Question

I’m running a stored procedure that involves more tables placed in joins.
My stored procedure do read operations on INNODB tables, writing to a temporary table created in this way

CREATE TEMPORARY TABLE IF NOT EXISTS tmpDate
(
dates TIMESTAMP,
values INT,
ids INT
);

and finally UPDATE operations on a column of a table (INNODB) in which surely there are no conflicting operations because i do on it only INSERT operations (SELECT and UPDATE just in that StoredProcedure).

Every time I run it I get the following error message:

Lock wait timeout exceeded; try restarting transaction

I immediately thought to be due to a hold to an exclusive lock.
Do you know a way to carry out NO LOCK table for a stored procedure or something that will allow me to execute my SP?

Answer 1

This error: "Lock wait timeout exceeded; try restarting transaction"
it’s a problem with MySQL database. I’ve restarted it and my stored procedure work fine. I don’t have found answer how to no lock table for full store procedure….
