MySQL 1194: Table needs repair.

To address the error "1194: Table needs repair" in a MySQL database, you can follow these steps:

  1. Identify the corrupted table that needs repair. The error message typically specifies which table is affected.



  1. Use the MySQL command line tool to log in to your MySQL server:


mysql -u your_username -p
Replace `your_username` with your MySQL username.

  1. Select the database containing the corrupted table:


USE yourdatabasename;
Replace `yourdatabasename` with the name of your database.

  1. Attempt to repair the table with the following SQL command:


REPAIR TABLE table_name;
Replace `table_name` with the name of the corrupted table. This command works for MyISAM and ARCHIVE tables.

If your table is of the InnoDB type, which doesn't support the `REPAIR TABLE` command, you might need to use the following approach:
- Dump the table:
mysqldump -u yourusername -p yourdatabasename tablename > table_name.sql
- Drop the table:
DROP TABLE table_name;
- Recreate the table from the dump:
mysql -u yourusername -p yourdatabasename < tablename.sql

  1. After running the repair command or restoring the table for InnoDB, verify that the table is accessible and the data is intact.



  1. It's also advisable to check MySQL's error log for any underlying issues that caused the table corruption, such as disk errors or crashes. The location of the log file depends on your MySQL configuration, but it can often be found in `/var/log/mysql/error.log` on Linux systems.



By following these steps, you should be able to repair the corrupted table and address the "1194: Table needs repair" error.

MORE ISSUES

MySQL Replication Lag
In a replication setup, a noticeable delay between master and slave, leading to outdated data on replicas.
MySQL Query Timeouts
Queries failing due to exceeding the configured timeout limits, often caused by complex or inefficient queries.
MySQL Frequent Crashes or Restarts
The MySQL server crashing unexpectedly or restarting often, possibly due to hardware issues, configuration problems, or resource exhaustion.
MySQL Frequent Deadlocks
Frequent deadlocks occurring during transactions, causing failed queries and rollback operations.
MySQL Full Disk/Storage Issues
Running out of disk space due to large logs, binary logs, or unoptimized data storage, leading to service disruptions.
MySQL InnoDB Buffer Pool Issues
Inefficient use of the InnoDB buffer pool, leading to high disk I/O because of frequent page swapping.
MySQL Table/Index Fragmentation
Fragmented tables or indexes leading to slower performance due to inefficient data access paths. This can often be mitigated by running OPTIMIZE TABLE.
MySQL Disk I/O Bottlenecks
Slow disk performance, often caused by poorly optimized queries, large temporary tables, or inadequate indexing.
MySQL High CPU/Memory Usage
The MySQL server consuming excessive CPU or memory resources, leading to system performance degradation.
MySQL Connection Issues
Hitting the maximum number of connections or connection timeouts due to poor connection pool management or high concurrency.
MySQL Lock Contention
Queries getting stuck due to high contention for row or table-level locks, causing delays or timeouts.
MySQL Slow Queries
Queries taking much longer than expected, especially under load or during complex operations like joins or large scans.
