How to lock a MySQL datasheet

When you perform a datasheet check or patch, you can lock the datasheet to ensure that the data table is secure:
Mysql>lock TABLE tbl_name READ;
Mysql>flush TABLES;
The task of checking or patching a data table before it is locked. Complete and then unlock:
Mysql>unlock TABLES;
Lock TABLE Tbl_name read indicates that you want to lock into a read-only state where the user can only read the data table and not write to it.
Lock TABLE Tbl_name Write is a more restrictive lock that the user cannot read or write to.
