1615 MySQL error | Resolved

by | Nov 21, 2021

1615 MySQL error making life difficult?

At Bobcares, we are devoted to coming up with solutions for every query, big and small, as a part of our Server Management Service.

Here is a recent example of how our Support Techs helped a customer overcome the dreaded MySQL error due to a MariaDB bug.

How to resolve the 1615 MySQL error

Has a MySQL error been causing trouble recently? This is a general error that seems to be a common problem.

Error code 1615 prepared statement needs to be re-prepared mysql

This error pops up due to a MariaDB bug.

According to our Support Engineers, we can resolve this error by adding the following section of mysqlconf file:

table_definition_cache = 1024

After that, we will restart MariaDB with this command:

systemctl restart mariadb.service

This will resolve the prepared statement needs to be re-prepared error. Furthermore, upping the table cache helps resolve the 1615 error. For instance:

[email protected]:/etc/mysql/mariadb.conf.d# mariadb
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 40
Server version: 10.3.31-MariaDB-0ubuntu0.20.04.1 Ubuntu 20.04


Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.


Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.


MariaDB [(none)]> show variables like 'table_definition_cache';
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| table_definition_cache | 1024  |
+------------------------+-------+
1 row in set (0.001 sec)


MariaDB [(none)]> \q
Bye
[email protected]:/etc/mysql/mariadb.conf.d#

Interestingly, error 1615 seems to be an ongoing issue. Increasing the table cache size is one of resolving the error. However, sometimes this solution may also backfire.

In such cases, our Support Engineers recommend using the SQL of view in a subquery rather than relying on the view in the prepared statement option.
