Why Do Hyphens Cause Errors in MySQL Table Names?

Using Hyphens (-) in MySQL Table Names

MySQL users sometimes encounter an error when trying to backup a database containing table names with hyphens. The error message typically indicates a syntax error related to the hyphenated table name.

To resolve this issue, it is necessary to enclose the table name in backticks (`) in the SQL query. This is also known as escaping the table name. When a table name contains special characters, numbers, or reserved keywords, it must be quoted for MySQL to correctly interpret it.

For example, consider the following query:

SELECT * FROM temp_01-01-000001

This query will result in the error mentioned above because the table name contains a dash (-). To correct this, the table name can be escaped using backticks:

SELECT * FROM `temp_01-01-000001`

With the table name enclosed in backticks, the query will execute successfully. This technique can be applied to any table name that contains special characters or reserved keywords.
