When Can I Use Special Characters in MySQL Table Names?

Using Special Characters in MySQL Table Names

When creating tables in MySQL, it is generally not advisable to use special characters in the table names. However, if you need to do so, there are ways to handle it.

Consider the example provided:

CREATE TABLE IF NOT EXISTS 'e!' (...);

This table name contains an exclamation mark (!), which is considered a special character in MySQL. To insert data into this table, you would need to quote the table name, as in:

INSERT INTO `e!` ...;

The backticks (`) serve to quote the ambiguous or "special" table name.

Alternatively, to avoid such quoting issues, it is recommended to simply avoid using special characters in table names altogether. This ensures compatibility with various database operations and eliminates the need for quoting or encoding.
