MySQL database is a relational database system which contains tables, these tables are formally described and they contain data within them. The data could be accessed and modify with various ways and there is no need for changing the order of tables for it. Pretty cool, Isn’t it? But sometimes corruption or mishandling of the data can lead us to errors. SQL Error 1146 Table doesn’t exist is also one of those common errors which can take place during MySQL handling.
So, in this handout, I’ll elaborate Error 1146 a.k.a. Table doesn’t exist, the reason behind this error and how to resolve MySQL code 1146. So without wasting time, let’s get started.
Why Error 1146 Takes Place?
There are multiple reasons and catalyst to this error. Some of the causes to error 1146 are stated below:
InnoDB crash and missing data files:
As we all know that InnoDB is the transaction-safe (ACID compliant) storage engine for MySQL database, it offers multiple capabilities like Rollback, Commit and crash recovery for data of MySQL database. The InnoDB is also prone to corruption, so if it is not handled correctly there is a chance of crash of InnoDB. InnoDB is functional because of ibdata file and log file. It acts as a data dictionary to it. If by any reason these files go missing, there will be no chance of working InnoDB and MySQL will show you error 1146.
Improper directory accessing permissions:
MySQL has a data storage directory where it stores all the database. Most of the time path is ‘/var/lib/mysql’. If the ownership and access permissions are not right and MySQL is not able to access this directory path then the MySQL code 1146 will be thrown.
Corruption in data tables:
Tables of MySQL database can get corrupt due to several reasons like improper server shutdown, incomplete queries, user abuse, wrong formats etc. So if the table got corrupt the database can show error ‘table doesn’t exist’.
.frm file missing
.frm file contains the format and structure of the database. If anyhow this file is not copied to the database directory or it gets deleted then there will be an error message for error code a.k.a. Table doesn’t exist.
