InnoDB: Error: Table "mysql"."innodb_table_stats" not found after upgrade to mysql 5.6

I previously addressed this issue in: Cannot open table mysql/innodb_index_stats

These tables are created for you when you install MySQL 5.6. However, upgrading from MySQL 5.5 does not invoke the creation of these tables. Here are the scripts to create them manually:

ALTERNATIVE

Another workaround would be to create the script from a MySQL 5.6 instance.

Step 01 : Goto a DB Server running MySQL 5.6, or install MySQL 5.6 on a test machine.

Step 02 : mysqldump these 5 tables to a text file

INNODB_TABLES="innodb_index_stats"
INNODB_TABLES="${INNODB_TABLES} innodb_table_stats"
INNODB_TABLES="${INNODB_TABLES} slave_master_info"
INNODB_TABLES="${INNODB_TABLES} slave_relay_log_info"
INNODB_TABLES="${INNODB_TABLES} slave_worker_info"
mysqldump -uroot mysql ${INNODB_TABLES} > InnoDB_MySQL_Tables.sql

Then, you can run InnoDB_MySQL_Tables.sql on any DB Server running MySQL 5.5 before upgrading.

Rolando's answer worked for me with some additions. I had the same problem, with these 5 tables showing via SHOW TABLES, but SELECT or other operations on the table resulted in table not found.

To resolve the issue, using Rolando's answer, I needed to:

• DROP TABLE <tablename> -- all 5 tables

• In the file system, delete the remaining .ibd files (the .frm files were removed by DROP TABLE)

• I then stopped and started the mysqld instance (don't know if it was needed - made me happy)

• The CREATE TABLE statements Rolando provided then ran without issue.
