Special Characters in MySQL Table Name

Question

I created a table as follows:

CREATE TABLE IF NOT EXISTS \'e!\' (
`aa` int(11) unsigned NOT NULL auto_increment,
`showName` TEXT NOT NULL default \'\',
`star         


        

Answer 1

Permitted characters in unquoted identifiers:

ASCII: [0-9,a-z,A-Z$_] (basic Latin letters, digits 0-9, dollar, underscore)

Extended: U+0080 .. U+FFFF

Permitted characters in quoted identifiers include the full Unicode Basic Multilingual Plane (BMP), except U+0000:

ASCII: U+0001 .. U+007F

Extended: U+0080 .. U+FFFF

ASCII NUL (U+0000) and supplementary characters (U+10000 and higher) are not permitted in quoted or unquoted identifiers.

Identifiers may begin with a digit but unless quoted may not consist solely of digits.

Database, table, and column names cannot end with space characters.
