MySQL Error codes 126, 127, 134, 144, 145
Example
When you try access the records from MySQL database, you may get these error messages. These error messages occurred due to corruption in MySQL database. Following are the types
MySQL error code 126 = Index file is crashed
MySQL error code 127 = Record-file is crashed
MySQL error code 134 = Record was already deleted (or record file crashed)
MySQL error code 144 = Table is crashed and last repair failed
MySQL error code 145 = Table was marked as crashed and should be repaired
MySQL bug, virus attack, server crash, improper shutdown, damaged table are the reason behind this corruption. When it gets corrupted, it becomes inaccessible and you cannot access them anymore. In order to get accessibility, the best way to retrieve data from an updated backup. However, if you do not have updated or any valid backup then you can go for MySQL Repair.
If the table engine type is MyISAM, apply CHECK TABLE, then REPAIR TABLE to it.
Then think seriously about converting to InnoDB, so this error won't happen again.
Syntax
CHECK TABLE <table name> ////To check the extent of database corruption
REPAIR TABLE <table name> ////To repair table
