If you get either of the following errors, it usually means that no table exists in the default database with the given name:
Table 'tbl_name' doesn't exist
Can't find file: 'tbl_name' (errno: 2)
In some cases, it may be that the table does exist but that you are referring to it incorrectly:
Because MySQL uses directories and files to store databases and tables, database and table names are case-sensitive if they are located on a file system that has case-sensitive file names.
Even for file systems that are not case-sensitive, such as on Windows, all references to a given table within a query must use the same lettercase.
